ABSTRACT The aim of this study was to analyze bone healing and vertical bone remodeling for implants placed immediately after tooth removal without guided bone regeneration techniques.
Twenty patients received 20 implants immediately after the removal of 20 teeth. All implants were placed within the undamaged alveoli confines, and the cervical portion of each implant was positioned at coronal bone level. The distance from implant shoulder and bone crest was measured for each implant at four sites (mesial, buccal, distal, and palatal/lingual). No membranes or filling materials were used. Primary flap closure was performed in all clinical cases.
All peri-implant bone defects had healed completely 6 months after implant placement. The pattern of bone healing around the neck of the implants showed an absence of peri-implant defects. The vertical distance between the implant shoulder and bone crest ranged from 0 to 2 mm.
The bone remodeling of implants placed in fresh extraction sockets showed a healing pattern with new bone apposition around the implant's neck and horizontal and vertical bone reabsorption. The vertical bone reabsorption, which has been observed at buccal sites, was not associated with any negative esthetic implications.

    ABSTRACT: The aim of the study was to evaluate the osseo-integration and soft tissue status of the endosseous implants placed in immediate extraction socket. Seven patients (4 males and 3 females) aged 20-30 years were selected for the study. Nine implants were placed in seven patients in the maxillary arch. All the patients were clinically αnd thoroughly examined. Under local anesthesia, the indicated tooth was extracted. The extracted socket was prepared using standard drills with palatal wall as guide. The longest and widest implants were placed (Hi-Tec Implants). All implants showed good primary stability. The implants used in the study were tapered design endosseous implants with Threaded implants (TI) unit plasma-sprayed surface. Surgical re-entry (secondary surgery) was performed to remove the healing cap after 6 months for supra crestal fabrication. All patients were reviewed periodically at 3(rd) and 6(th) month interval and the following clinical parameters including modified plaque index (mPlI), modified bleeding index (mBI), probing depth (PD), attachment level (AL), and distance between the implant shoulder and mucosal margin (DIM), distance between the implant shoulder and first bone-implant contact, and Clinical Mobility Index were recorded. The results were computed and subjected to statistical evaluation. The mPlI, mBI, PD, AL, and DIM were evaluated around the implants at baseline, 3(rd) and 6(th) month intervals and analyzed statistically by Friedman T-test. The results of the above were shown to be statistically non-significant. The distance between the implant shoulder and first bone implant contact was evaluated around the implants at base line, 3(rd) and 6(th) month intervals. The results proved to be statistically significant (0.01) implying that there was a bone apposition around the implants. During the course of the study, soft tissue status around implants was found to be healthy. Osseointegration as assessed by clinical and radiographic findings was found to be sound.

    ABSTRACT: Implant therapy has become a reliable and predictable treatment alternative for the replacement of missing teeth with conventional removable and fixed partial dentures. Recently though, in the pursuit for improved esthetics, the literature has dedicated a considerable amount of its research on the successful maintenance and regeneration of the surrounding gingiva and bone, which are lost following extraction of a tooth. Thoroughly analyzing the anatomic situation and well-planned treatment has become a requirement, because incorrectly planned and positioned implants may jeopardize long-term esthetic and functional prognosis. In addition, many types of biocompatible materials, autogenous hard and soft tissue grafts, and different surgical techniques have been developed, and their viability has been investigated. As a result, implant specialists have gained a greater understanding of the dynamics and anatomical and biological concepts of the periodontium and peri-implant tissues both at the surgical and prosthetic phases of treatment, which contributes to better soft and hard tissue management (SHTM). This may further contribute to achieving a superior final result which is obtained by having a harmonious soft tissue profile, a correctly placed and contoured final restoration, and the reestablishment of masticatory function and phonetics.

    ABSTRACT: Root fracture is a combined injury of cementum, dentin, and pulp. Many of these traumas remain untreated, mistreated, or overtreated. It leads to a more complicated treatment in case of tooth loss. Many different treatment procedures, with a very changeable success rate, have been proposed for years to treat teeth with root fractures. The objective of the following clinical studies was to evaluate the clinical effectiveness of implants placed in fresh extraction sites to treat teeth with horizontal root fracture. The study group included 25 patients (15 men and 10 women) between the ages of 20 and 65 years. After an initial examination and a treatment planning, all of the patients underwent periodontal treatment, which was deemed necessary to favor wound healing. All the 25 teeth were extracted because of horizontal root fracture located at the level of the middle third. The second-stage surgery was performed 6 months after the initial procedure. The following clinical parameters, presence or absence of mobility, presence or absence of pain, and presence or absence of suppuration, were evaluated in each patient at 6 and 12 months after implant placement. Radiographs were taken using the standard method to evaluate the marginal bone loss. The healing period was uneventful for all patients. All implants had osseointegrated. After 12 months, patients were asymptomatic and showed no signs of infection or bleeding when probed. On the basis of this study, implants placed right after tooth extraction are a valid treatment procedure, which induces predictable results as treatment of fractured teeth.
