Abstract
Implant dentistry has evolved into the mainstream of restorative practices all over the world. Maintenance of bone after tooth loss to improve or maintain facial esthetics and improved retention, function, and performance of removable restorations are only some of the advantages for the edentulous patient. No longer are implants considered only when traditional restorations cannot be fabricated. Evidence-based reports indicate implant restorations last longer than those on teeth and the abutment teeth are at less risk of loss or complication.
... Moreover, removable prosthesis is not able to be satisfactory for the patient in terms of stability and function as fixed prosthesis. This situation dictates the need for dental implants, which is one of the successful and predictable treatment procedures to replace the lost teeth [28]. ...
... In the original techniques, a controlled fracture was done then implants were placed and submerged during the healing phase [32]. Summers proposed a procedure in 1994 that allowed for implant insertion and elevation of the sinus floor from a crestal approach using an osteotome [28]. ...
Purpose
The present study was conducted to evaluate the effect of using ozone gel with transcrestal sinus elevation using osteotomes, on the bone width and the buccal plate of bone thickness around the implants placed simultaneously.
Materials and methods
A total of 30 sinuses with an average residual alveolar bone height ranging from 4–7 mm participated in this randomized controlled clinical trial. Following a closed sinus lift procedure, patients were randomized into two groups: one for the ozone gel recipient group and the other for control group. Cone beam computed tomography was carried out both immediately and four months postoperatively. Radiographic evaluations were performed to assess bone width and labial plate thickness at both crestal and midcrestal levels.
Results
Radiographic analysis revealed that the mean bone width of the control group after four months postoperative was (8.54 ± 1.46 mm) compared to (8.96 ± 1.66 mm) in the study group, which was statistically insignificant (P ≤ .0.05). The mean labial plate of bone thickness value of the control group after four months postoperative was (1.86 ± 0.63 mm) compared to (1.89 ± 0.51 mm) in the study group. Although the bone dimensions in the study group was higher than the control group, it was statistically insignificant (P ≤ .0.05).
Conclusion
When compared to the graftless group, the ozone gel recipient group showed non-significant difference in the results in terms of bone width and thickness. Both methods, nevertheless, produced outcomes that were acceptable.
Trial registration
This study protocol was retrospectively registered on the trial registry “Clinical trials.gov PRS”. ClinicalTrials.gov ID is: NCT06604819 and the registration date is 20/9/2024.
... Devido ao rebordo alveolar superior ser favorável e sem necessidade de osteotomia para espaço protético, foi indicada cirurgia guiada para prótese do tipo protocolo fixa sobre implantes na maxila. A reabertura dos implantes foi realizada após 6 meses de osseointegração dos implantes, sendo selecionados 4 minipilares cônicos (Neondent) de 2,5 mm de transmucoso (12,14, 22 e 26), 1 minipilar de 1,5 mm (16) e 1 de 3,5 mm (24). Os pilares foram instala-dos com torque de 32N e os transferentes (Neodent) acoplados com parafusos de fixação curtos. ...
... Ciente disso, a associação de informações clínicas com exames de imagens de alta qualidade, como as TCCBs, é o ponto chave para o aperfeiçoamento de um planejamento reverso e, consequentemente, uma reabilitação final previsível e precisa. Isso pôde ser validado comparando a tomografia inicial com a tomografia realizada após a instalação dos implantes por esse e outros estudos 12,14 . ...
A reabilitação oral de pacientes totalmente desdentados vem evoluindo com o avanço das técnicas cirúrgicas em Implantodontia. A realização de procedimentos para instalação de implantes osseointegrados com auxílio de tomografia computadorizada cone beam possibilita a conversão de imagens através de softwares especializados, o que permite a confecção de protótipos e guias cirúrgicos previamente planejados virtualmente. Associado a isso, os procedimentos cirúrgicos tornam-se previsíveis e com trauma reduzido, aumentando o conforto trans e pós-operatório para o paciente. Este estudo teve por objetivo descrever um caso clínico de reabilitação total em maxila edêntula por meio de cirurgia guiada e carga tardia. A paciente em questão foi criteriosamente avaliada e todas as possibilidades de tratamento foram descritas. Uma prótese do tipo protocolo All-on-4 inferior e uma prótese total mucossuportada superior foram realizadas em uma primeira etapa de tratamento, seguida de planejamento virtual tomográfico por software Dental Wings para cirurgia guiada de implantes superiores e posterior instalação de prótese protocolo superior. O plano de tratamento, sobretudo por conta da cirurgia guiada sem retalho, proporcionou menor tempo e trauma operatório e, principalmente, uma excelente previsibilidade ao posicionamento tridimensional dos implantes, favorecendo a obtenção de uma prótese adequada em termos de distribuição de forças.
... INTRODUCTION Implant dentistry has evolved into the mainstream of restorative practices all over the world. 1 It has mainly two phases; a surgical phase and a prosthodontic phase. For centuries, there were ways to replace the crown but not the root but root replacement is now possible. ...
... Literature shows that the main advantage of dental implants as compared to other tooth-replacement modalities is they are more conservative as there is no need of preparing natural teeth as in conventional partial dentures. 1,15,17 Duration of longitudinal studies on survival of implants in the literature is upto 20 years. [18][19][20] So, the expected answer for the longevity of dental implants was 10-20 years. ...
Introduction
Awareness about dental implants is increasing among dental patients, which demands a higher level of competence for dental students. So, the objective of this study was to assess the knowledge and perception of undergraduate dental students about dental implants.
Materials and methods
This cross-sectional questionnaire-based survey was conducted after taking ethical clearance and approval from the Institutional Review Committee of B.P. Koirala Institute of Health Sciences and informed consent from each dental college of Nepal. The sample included all those students who were present at the time of survey. Data collection were carried out during the academic schedules of the colleges, supervised, and monitored by the investigators themselves. Collected data were coded, entered in Microsoft excel 2013 and descriptive analysis was carried out.
Results
A majority of the total (54.6%) and 59.2% of 5th year respondents perceived to be moderately well-informed about dental implants. The main advantage of dental implants was thought to be longevity by 53.1% of total and 48.4% of 5th year students; only 27.6% of the total and 42.2% of 5th year students said the main advantage of dental implants is they are more conservative than other tooth-replacement modalities. Highest percentage of the total respondents (31.9%) said most important factor for implant success to be implant type and material, whereas 59.8% of 5th year students said case selection. Those who felt dental implants require additional oral hygiene maintenance and care by the patient and dentist were 58.4% of total and 75.1% of 5th year students. Over two-thirds (67.5%) of total thought that economic feasibility will limit use of dental implants in Nepal. The difficulty encountered to place implants was perceived to be average by 56.8% of total and 58.1% of 5th year. There were differences in the perception and knowledge at different academic levels, but not as expected.
Conclusions
It could not be concluded that knowledge about dental implants increased with increase in academic level. Even at the late-clinical year a majority of students gave unsatisfactory responses.
... Dental implants are another viable treatment option for the management of missing teeth in the mandibular region. Fixed dental implant-supported prosthetics (FPD) have many advantages over conventional crowns and bridges or RPDs (removable partial dentures) [6]. Using dental implants offers numerous benefits, including the maintenance of residual bone, increased longevity, non-involvement of adjacent teeth, and ease of oral hygiene. ...
The most frequent reasons why people lose their teeth are trauma, dental caries, developmental defects, and genetic abnormalities. Dental implants have become a popular alternative to traditional dentures and bridges due to their ability to restore function through osseointegration. This case report presents a 35-year-old male with a two-year history of a missing lower right molar due to caries. With no systemic health issues or harmful habits, the patient underwent dental implant placement after a thorough evaluation and cone-beam computed tomography (CBCT) analysis. A parallel-sided, threaded implant was placed in the 46 region. Postoperative care included antibiotics, analgesics, and follow-up visits. Second-stage surgery was done, which was followed by impression-making and healing abutment placement. The final crown was cemented with careful occlusion verification. The patient exhibited excellent healing and was scheduled for regular follow-ups to ensure successful implant integration and function restoration.
... This report highlights the importance of meticulous planning and precise execution in achieving esthetic perfection in maxillary anterior region. 9 Opting for dental implants in this region offers significant benefits, with fixed implant-supported prosthetics showcasing multiple advantages over conventional crown and bridge or removable tooth-supported options. 10 Among the treatment options considered were removable partial dentures, fixed partial dentures, and resin-bonded bridges, each with drawbacks. ...
This case study delves into the complex process of esthetic restoration in the anterior maxilla, highlighting the careful planning and precise execution needed to achieve optimal results. Tarting with a thorough assessment of the patient's dental health, including bone structure and soft tissue condition, a customized treatment plan was crafted through the collaborative efforts of the implant surgeon and restorative dentist. The surgical placement of a single tooth implant was performed with precision, ensuring optimal positioning and angulation to achieve natural-looking results while preserving the surrounding tissues. Prosthetic restoration utilized carefully chosen materials and techniques to integrate seamlessly with the natural teeth. Through interdisciplinary collaboration and precise attention to detail, the anterior maxilla was successfully esthetically rehabilitated, showcasing the transformative capabilities of modern implant dentistry.
... Assessment of surrounding tissue, screw replacement is easy and it required only radiographic verification. According to Misch, the success rate for a single implant is 97% for 10 years [2]. The long-term durability and success of these implant prosthesis depend on the precise fit and maintenance of the prosthesis. ...
... It is not a surprise to find approximately half of dentists questioned have not experience nor idea about ridge augmentation procedures in both atrophic mandible and maxilla as removable prosthesis are annoying to patients and dentists are usually concerned more about implant dentistry than unpredictable results of dentures and also rapid progress of dental implants attract dentists to solve problems of retention, stability and comfort of conventional dentures [8]. ...
Abstract:
Objective: The aim of this study is to evaluate the attitude and awareness of sample of Libyan dentists towards preprosthetic surgery.
Materials and methods: An observational study was undertaken for 150 registered dentists with a Bachelor of Dental Surgery degree, currently practicing in different cities of Libya. Only 109 dentists respond to our questions. Dentists with <5 years in Practice and who have no experience with removable prosthesis were excluded. This study was approved by the research ethical committee of Faculty of Dentistry-Benghazi university. Previous studies were used to prepare a questionnaire which include questions about personal data, awareness and preference of dentist of preprosthetic surgery. Questionnaire was assessed by two expert oral- maxillofacial surgeon and prosthodontist.
Results: Out of 150 dentists to whom the questionnaire was sent, only 109 answered the questions. The study included 64 (58.7%) male and 45 (41.3%) female with male to female ratio 1.4:1. The age range of the participant was 30 to 52 years old. Regarding the years of practice, 18.1% had 5 years, 26.7% had 5-10 years and majority (55.2%) had more than 10 years of experience in practice of removable prosthesis. 41.9 % of participant constructing more than 10 dentures per year, 22.9% of dentists perform 5-10 denture insertion per year and 35.2% perform 3-5 dentures per year.
Conclusion: For surgeons to satisfy the needs of denture providers, it is advisable that oral and maxillofacial surgeons consult with the dentists who will construct the prosthesis rather than relying solely on their own opinion about what should be done for the patient.
... [ GRAPH 12] Literature shows that the main advantage of dental implants as compared to other tooth-replacement modalities is they are more conservative as there is no need of preparing natural teeth as in conventional partial dentures (Misch, 2001)(Chaudharyet al., 2015) (Jivraj and Chee, 2006). Prosthodontic rehabilitation of missing teeth has greatly evolved especially with the introduction of dental implants. ...
... 1 Recently, Implant dentistry has evolved into the mainstream of restorative practices all over the world. 2 It has mainly two phases; a surgical phase and a prosthodontic phase. Endoseous dental implants are alternative tooth roots and implant supported prostheses are considered the best substitute for missing teeth. ...
Background: Dental implant therapy is still considered an evolving field in Nepal, with most dentists favoring implant placement following the delayed loading protocol (>3 months) even in the rehabilitation of missing anterior teeth. There is need to understand the clinical difference between immediate and delayed loading protocols of the dental implants. With advent of immediate loading protocol of dental implants, instant rehabilitation in addition to better esthetics and self-confidence can be obtained.
Aims and Objectives: This study aims to evaluate the knowledge and attitude of general dentist towards immediate loading protocol of dental implants.
Materials and Methods: A descriptive, cross sectional survey was conducted among Nepalese general dentists who have entered their clinical practice in private or government hospital regardless of their years of experience. A self-administered questionnaire adapted from some previous studies was framed and distributed with the primary objective to determine their knowledge and attitude towards immediate loading protocols of dental implants. Data collected were analyzed using the Statistical Packages for the Social Sciences version 22 (IBM Corp, Armonk, NY, USA).
Results: Among the 250 participants included in this study, 94.8% of the respondents completely filled the questionnaire. Nearly 46.4% of participants had good knowledge on the procedure and advantages offered by the immediately loaded dental implants with provisional restorations, whereas 83.1% had negative reservations toward implant placement using the protocol. In addition, this study found a statistically significant association (p
... Implant dentistry has evolved into the mainstream of restorative practices everywhere in the world. (Misch, 2001) The two significant phases are a surgical phase and a prosthodontic phase. For hundreds of years, there have been ways to exchange the crown but not the root but root replacement is now possible. ...
... While various treatment approaches for congenitally missing teeth have been proposed, outcome data pertaining to these treatment options are lacking [2]. Replacement of a missing tooth with a dental implant offers specific advantages over other options for tooth replacement such as removable or fixed dentures [3]. These advantages include preservation of the alveolar crest, elimination of the need to restore adjacent teeth, and improved esthetics and function. ...
The aim of this article is to present the clinical application of immediate implant placement with L-PRF and immediate prosthetic loading in anterior esthetic region. A 24-year-old healthy female patient reported with a chief complaint of poor esthetics in the upper front tooth region with retained deciduous teeth. On oral examination, there were retained deciduous teeth (52, 53, and 63) with congenitally missing permanent successors. The retained deciduous teeth were extracted, and immediate implant placement was done in the extraction sockets along with L-PRF membranes in one surgical session under local anesthesia. Immediate temporization was performed with composite crowns on immediately placed dental implants. After 3 months of the healing period, the final implant-level impressions were made and the temporary composite crowns were replaced with the final zirconia porcelain crowns. A 12-month follow-up was made, and satisfactory esthetic and functional results were obtained.
... There are many benefits of fixed dental implant-supported prosthetics versus traditional crown and bridge or removable toothborne prosthetics. 9 Maintenance of residual bone, ease of oral hygiene, increased longevity, and non-involvement of adjacent teeth are a few advantages of using dental implants. In order to provide successful and aesthetic dental implant treatment, certain clinical parameters must be met. ...
Implant therapy is today widely regarded as a reliable treatment option to replace missing teeth, both for function and esthetics. Dental implants may be used to replace single teeth, replace multiple teeth, or provide abutments for complete dentures or partials. This topic focuses on the placement of single-tooth dental implants. The correct surgical placement of a dental implant is mandatory to obtain the ideal aesthetic result. Only through proper treatment planning can the correct position and number of implants be determined. Before surgical placement of a dental implant, the adequate hard and soft tissue must be available. The clinician must consider the time needed for implant integration and soft-tissue healing, creation of emergence profiles, occlusal forces in relationship to progressive loading, and occlusal forces on the final restoration.
... The benefits of retaining a tooth have been discussed (13,(114)(115)(116)(117). Factors influencing implant choice, prognosis, and management have also been listed (118)(119)(120)(121). However, clinicians tend to disagree on treatment choices (122). ...
Introduction:
Clinicians are regularly confronted with difficult choices. Should a tooth that has not healed through nonsurgical root canal treatment be treated through endodontic microsurgery or be replaced using a single implant? Acquiring complete, unbiased information to help clinicians and their patients make these choices requires a systematic review of the literature on treatment outcomes. The purpose of this systematic review was to compare the outcomes of tooth retention through endodontic microsurgery to tooth replacement using an implant supported single crown.
Methods:
Searches performed in PubMed, Cochrane Library, Web of Science, and EMBASE databases were enriched by citation mining. Inclusion criteria were defined. Sentinel articles were identified and included in the final selection of studies. Weighted survival and success rates for single implants and endodontic microsurgery were calculated.
Results:
The quality of the articles reporting on single implants and endodontic microsurgery was moderate. Data for single implants were much more plentiful than for endodontic microsurgery, but the endodontic microsurgery studies had a slightly higher quality rating. Single implants and endodontic microsurgery were not directly compared in the literature. Outcomes criteria were often unclear. At 4-6 years, single implants had higher survival rates than teeth treated with endodontic microsurgery. Qualitatively different success criteria precluded valid comparison of success rates.
Conclusions:
Survival rates for single implants and endodontic microsurgery were both high (higher for single implants). Appraisal was limited by a lack of direct treatment comparisons. Long-term studies with a broad range of carefully defined outcomes criteria are needed.

Hopeless retained primary teeth without permanent successors represent a restorative challenge for clinicians, along with esthetic and functional problems for patients. While various treatment approaches for congenitally missing teeth have been proposed, the replacement of a missing tooth with a dental implant offers specific advantages, such as preservation of the alveolar crest and elimination of the need to restore the adjacent teeth, over other options for tooth replacement. The aim of this article was to illustrate the surgical and prosthetic treatment with implants of a patient with primary teeth without permanent successors.
Dental implants have proven to be one of the most significant advancements in modern dentistry. This technology allows the replacement of one or more artificial teeth with predictable results. Dental implants significantly improve an individual’s ability to eat resulting in improved general health and quality of life. This chapter provides a basic understanding of dental implant science and includes potential risks and complications that may be encountered in a medical practice.
In this chapter we discuss the recent nanomaterials and nanoscaffolds that can deliver drugs, signaling molecules, growth factors, and cells for tissue engineering in managing and treating periodontal and implant diseases.

Odontogenic infections (OI) are a major reason for consultation in dental practice. They affect people of all ages, and most of them respond well to current medical and surgical treatments. The aim of this paper is to emphasize different and rare etiological factors that can play a role in odontogenic abscesses, which can lead to complications. A 54-year-old man complaints of pain and swelling on the upper front-side of his face. Physical examination of the face showed enlargement and swelling in the upper front region. Panoramic radiograph images showed a radiolucent appearance of the canine region. Based on the results of the clinical and radiographic examinations, the patient was diagnosed with a bilateral canine space infection. The treatment performed was FNAC (Fine neddle aspiration cytology) from canine region followed by intraoral drainage incision at the most prominent part of swelling (Modified Hiltons method), 5 ml of pus was removed, postoperative dressing was applied and regular follow-up was done with continued antibiotic therapy. Bilateral canine space abscess is a rare odontogenic infection that can cause life-threatening complications. The success of treatment requires early recognition, determination of etiological factors, and appropriate medical and surgical management. To perform treatment of odontogenic infections, the Oral & Maxillofacial Surgeon should understand the terminology regarding infectious diseases and pathophysiology. The success of treatment requires early recognition, determination of etiological factors, and appropriate medical and surgical management.
Background The surgical placement of implants into maxillary extraction sites in ovariectomized (OVX) rats could mimic implant placement in compromised bone in humans, such as is seen in osteoporosis. Purpose This study was designed to evaluate the effects of osteoporosis on osseo-integration around titanium implants following extraction in the posterior maxilla of OVX rats. Materials and Methods Forty-four 3 month old female Sprague-Dawley rats were used in this study. The rats were randomly divided into two groups: Sham-operated group (SHAM; n = 22) and ovariectomized group (OVX; n = 22). Surface-treated screw-shaped titanium implants were immediately inserted into the mesial extraction sites of the first molar in the posterior maxilla following tooth extraction. The animals were sacrificed at either 28 or 56 days post-surgery, and undecalcified tissue sections were processed for histological analysis. Bone-to-implant contact (BIC) and bone density (BD) were evaluated. Results With a carefully planned and executed surgical implant protocol, implant placement following extraction in the posterior maxilla can produce reproducible results. The BIC and BD in the OVX group were significantly inferior to those in the SHAM group at both 28 and 56 days, which indicated that osteoporosis could reduce the amount of osseo-integration of dental implants in the posterior maxilla. Conclusion This study demonstrated that osseo-integration (BIC and BD) was inferior in implants following extraction in the posterior maxilla of OVX rats, especially in the early healing period, indicating that lower local bone quality in OVX rats can reduce early bone formation on implant surfaces.
This article reviews the literature on the outcome of flapless surgery for dental implants in the posterior maxilla. The literature search was carried out in using the keywords: flapless, dental implants and maxilla. A hand search and Medline search were carried out on studies published between 1971 and 2011. The authors included research involving a minimum of 15 dental implants with a follow-up period of 1 year, an outcome measurement of implant survival, but excluded studies involving multiple simultaneous interventions, and studies with missing data. The Cochrane approach for cohort studies and Oxford Centre for Evidence-Based Medicine were applied. Of the 56 published papers selected, 14 papers on the flapless technique showed high overall implant survival rates. The prospective studies yielded 97.01% (95% CI: 90.72-99.0) while retrospective studies or case series illustrated 95.08% (95% CI: 91.0-97.93) survival. The average of intraoperative complications was 6.55% using the flapless procedure. The limited data obtained showed that flapless surgery in posterior maxilla areas could be a viable and predictable treatment method for implant placement. Flapless surgery tends to be more applicable in this area of the mouth. Further long-term clinical controlled studies are needed.

The use of dental implants for single-tooth replacement has been established as a predictable treatment option; yet, limited data are available as to how frequently this option is recommended to patients. The aim of the present study was to examine the frequency of implant recommendation by general dental practitioners after single-tooth extraction and factors influencing their decision to recommend an implant. All single-tooth extractions performed in 26 general dental practice clinics in Kuwait over a 30-day period were examined. Dentists in these centers used the study form to record demographic data, the type of tooth extracted, reason for extraction, and replacement options presented to the patients. Univariate and logistic regression analyses were used to examine associations between background factors and decisions to recommend implant therapy. A total of 1367 patients (mean age, 37.9 +/- 11.8 years) had an extraction of one tooth during the study period. Forty-three patients were offered implants as a replacement option (3.3% of the total sample; 8.6% of patients who were offered tooth replacement options). Factors associated significantly with the recommendation of an implant by Kuwaiti dentists to their patients included younger age, regular dental maintenance visits, and adequate oral hygiene practices (P < 0.05; binary logistic regression). Dental implant recommendation for single-tooth replacement in the present sample of dentists was low. Factors associated significantly with dentist recommendation of an implant for single-tooth replacement included age, history of dental maintenance, and oral hygiene practices.
Hopeless retained deciduous teeth without permanent successors pose a restorative challenge for clinicians as well as certain clinical problems for patients. Compromised aesthetics, shifting of adjacent teeth, altered occlusion, and supereruption of teeth are examples of problems that can arise when a permanent tooth is congenitally missing. Mattheeuws, et al1 reported that the mandibular second premolars are the permanent teeth most often congenitally missing, followed in prevalence by the maxillary lateral incisors and the maxillary second premolars. Larmour, et al2 reported that in Caucasians the mandibular second premolars and maxillary lateral incisors were the teeth most frequently absent, while in Asians the mandibular incisors were the most frequently missing teeth. The condition of having less than 6 congenitally missing teeth is termed hypodontia. Hypodontia is a multifactorial condition and in certain cases has been associated with a number of systemic conditions and dental anomalies.2 The prevalence of hypodontia is reported to range from 2.6% to 11.3%, based mainly on radiographic studies. There is a 3:2 female-to-male ratio for hypodontia.2 If one or a few permanent teeth are congenitally missing without any systemic disorders, this is considered to be an autosomally inherited dominant condition with varying gene expression and incomplete penetrance.3 While various treatment approaches for congenitally missing teeth have been proposed, outcome data pertaining to these treatment options are lacking.4 Replacement of a missing tooth with a dental implant offers specific advantages over other options for tooth replacement such as removable dentures or a fixed bridge.5 These advantages include preservation of the alveolar crest, no need to restore the adjacent teeth, and improved aesthetics and function. By understanding the principles of treatment planning, implant surgery, and implant restoration, a clinician can successfully replace a hopeless retained deciduous tooth with a dental implant. This article will discuss the treatment planning and surgical and prosthetic principles for the replacement with implants of hopeless retained deciduous teeth. A case presentation will be used for illustration.
