    ABSTRACT: This preliminary study investigated the influence of different oral prosthodontic interventions on quality of life related to voice and oral health in elderly people and the relation between these conditions. Forty-five elderly people who had completed prosthodontic rehabilitation treatments were divided into three groups according to dental conditions and answered two protocols: voice-related quality of life and oral health impact profile. Despite the small sample size, the elderly people in this study presented no differences between the groups and showed a relationship between oral and vocal health aspects.

    ABSTRACT: A preliminary tensile test was performed to evaluate the mechanical properties of cobalt-chromium (Co-Cr) alloys fabricated by three new manufacturing processes: metal milling, milling for soft metal, and rapid prototyping (n = 6). For comparison, the three alloy materials were also used to fabricate specimens by a casting procedure. In all groups tested, the proof strength and elongation were over 500 MPa and 2%, respectively. The milled soft alloy in particular showed a substantially greater elongation, whereas the alloy fabricated by rapid prototyping exhibited a higher proof strength.

    ABSTRACT: This study analyzed the shear strength and fracture characteristics of the interface between zirconia samples and their veneering ceramic compared with a metal-ceramic and a lithium disilicate glass-ceramic control group together with an assessment of the possible relationship between the fracture characteristics and the recorded shear strength. The greatest shear strengths corresponded to the lithium disilicate glass-ceramic control group followed by the metal-ceramic control group, with lesser strengths in the zirconia groups. Since the fractographic study showed cohesive-type failure to predominate in the zirconia samples, it is concluded that improvements are needed in the veneering ceramic and liner used in zirconia restorations.

    ABSTRACT: Ultrasonography has been extensively explored in dentistry because of its several diagnostic advantages. The purpose of this study was to determine the thickness of the maxillary attached gingiva with the use of a high-frequency ultrasound in subjects with sex-, age- and smoking-related differences. A total of 100 healthy subjects (70 women and 30 men, age range: 18 to 55 years) were included. A special B-scan unit was used to measure the soft tissue thickness in the buccal and palatal attached gingiva in the maxillary arch. Aquasonic 100 Ultrasound Gel (Parker Laboratories) was used as coupling medium. Student t test was used for statistical analysis of the subgroups with different parameters with significance set at P < .05. A total of 2,734 measurements showed that male nonsmokers have a significantly thicker fixed gingiva than nonsmoking women and that age does not seem to have great influence on the thickness of the gingiva. Smoking had a significant effect, but only on the oral maxillary gingival tissues of women. The palatal gingiva was found to be significantly thicker in female smokers than in nonsmoking females. Measurement of gingival thickness for different purposes using a B-scan ultrasonic device appears to be a reliable method. Sex- and smoking-related differences in the gingival thickness exist only on the palatal side among women.

    ABSTRACT: This survey of German dental schools sought to gain insight into the present prosthetic treatment concepts and their application in student and postgraduate education, as well as to compare the results to those from an identical 2002 survey. A questionnaire, based on this issue, was sent via email to the chairpersons of all prosthetic departments of the German dental schools, and 93.1% of the departments completed the questionnaire. Within the limitations of this survey, almost all treatment concepts for the reduced dentition are taught intensively at dental schools in Germany while some therapy forms are preferred.

    ABSTRACT: This study compared the distribution of forces in relation to the area covered by the denture base. Seven participants were fitted with a loading device on the maxilla and were guided to bite on an experimental mandibular denture. The denture base was progressively shortened from full coverage of the retromolar pad. One-way analysis of variance (P < .05) was performed, and no significant difference was found among the four denture base lengths in relation to force distribution. Within the limitations of this study, the authors conclude that the area covered by the retromolar pad has little influence on force distribution during loading.

    ABSTRACT: The aim was to report on oral rehabilitation of a boy with X-linked hypohidrotic ectodermal dysplasia (XLHED) and anodontia of the mandible between ages 3 and 33 years where treatment involved dental implants and oral care management by a multidisciplinary team of specialists. This case history report describes the clinical management of a boy born in 1979 with XLHED and anodontia of the mandible. Two implants were successfully placed in the anterior region of the mandible in 1985. Genetic analysis later verified the diagnosis by confirming a mutation in the EDA gene. The case description was based on review of the patient records and assessment of orofacial function. The patient had satisfactory orofacial appearance and function throughout his youth. He is still caries-free at age 33 and has experienced only minor oral complications. Dental management began at age 3, when he received a maxillary removable dental prosthesis. At age 7, he received a mandibular implant-supported overdenture. After two more implants in the mandible and orthodontic treatment in the maxilla, his oral rehabilitation was completed at age 22 with maxillary tooth-supported and mandibular implant-supported fixed dental prostheses. Regular follow-ups provided supervision of oral hygiene, caries prevention, and prosthetic maintenance. This long-term follow-up of a child with XLHED and anodontia in the mandible supports the use of dental implants, with consideration given to the dense bone quality associated with the diagnosis, to establish good orofacial function and appearance from childhood onward.

    ABSTRACT: This study assessed the use of the commercial artificial teeth setup device Staub Cranial System (Neu-Ulm) in Asian subjects. Fourteen completely dentate Thai volunteers were randomly recruited. Study casts (control group) and duplicated casts (experimental group) of all subjects were prepared. Artificial teeth were replaced on duplicated casts according to the manual. Computed tomography scans of all casts were performed. Intercanine width, intermolar width, incisocervical length, and occlusal plane were investigated. The length of the natural mandibular left central incisor was smaller than the reconstructed one. The reconstructed occlusal plane was more parallel to the hamular-incisive papilla plane than that of the control group.

    ABSTRACT: The purpose of this noninferiority study was to determine whether removable or implant-supported fixed dental prostheses restored patients' abilities to preoperative levels after cancer removal in the mandible. Ten patients who had undergone mandibular resection to remove cancer and subsequent reconstruction with microvascularized free fibula flaps were examined in this study. Five patients were rehabilitated with removable prostheses and five received implant-supported fixed prostheses. Health-related quality of life was evaluated using the Head and Neck (H&N30) questionnaire. Kruskal-Wallis nonparametric analysis of variance and Tamhane's T2 test were used to analyze results in comparison with a control group composed of 10 subjects with Class I natural dentition. Masticatory efficiency among the three groups of patients differed significantly (P = .003); in particular, that of the patients who received removable prostheses was not inferior to that of the control subjects (P = .019). Analysis of responses to the Head and Neck module of the Quality of Life Questionnaire showed no significant difference between patients with fixed dentures and patients with removable dentures. There is no apparent difference in quality of life between patients using implant-supported fixed prostheses and those using removable prostheses. Regarding masticatory efficiency, when feasible, the use of implantsupported fixed prostheses is recommended in patients who have undergone free fibula flap surgery, although the removable prostheses also were not inferior in patients who underwent no surgery.

    ABSTRACT: The objective of this preliminary study was to determine if the occlusal contact surface registered with an articulating paper during fixed prosthodontic treatment was contained within the area marked on a thicker articulating paper. This information would optimize any necessary occlusal adjustment of a prosthesis' veneering material. A convenience sample of 15 patients who were being treated with an implant-supported fixed singleunit dental prosthesis was selected. Occlusal registrations were obtained from each patient using 12-μm, 40-μm, 80-μm, and 200-μm articulating paper. Photographs of the occlusal registrations were obtained, and pixel measurements of the surfaces were taken and overlapped for comparison. The results showed that the thicker the articulating paper, the larger the occlusal contact area obtained. The differences were statistically significant. In all cases, the occlusal registrations obtained with the thinnest articulating paper were contained within the area marked on the thickest articulating paper. The results suggested that the use of thin articulating papers (12-μm or 40-μm) can avoid unnecessary grinding of veneering material or teeth during occlusal adjustment.

    ABSTRACT: The aim of this study was to evaluate the changes in the masticatory functions of complete dentures before and after the insertion of a LOCATOR attachment. The mixing ability index with a two-colored paraffin wax cube was used to quantify masticatory performance. In addition, degree of satisfaction with the treatment was assessed using a visual analog scale. The mixing ability index for the implant-retained overdentures and the complete dentures were calculated (-0.03 ± 1.38 and -2.10 ± 1.57, respectively), as were the visual analog scales of the implant-retained overdentures and the complete dentures (8.9 ± 1.5 and 4.3 ± 1.7, respectively). The paired t test revealed significant improvements (P < .001).

    ABSTRACT: Prosthodontically driven biomechanical considerations are essential for longterm successful outcomes in dental implant therapy. Correct protocols seek to preclude potential consequences associated with functional and parafunctional occlusal overload such as screw loosening, component fracture, compromised marginal bone maintenance, and the integrity of the induced osseointegration response. Other concerns also need to be addressed, more especially when other implants are selected, for example: bridge insertion torque (BIT) in cases of immediate loading, cantilever length-anteroposterior spread ratio (CL-AP), overall crown-to-implant ratio (oCIR), total bone-to-implant surface area (tBICA), and the status of the opposing dentition. In spite of promising clinical results, evidence-based clinical protocols demand that such biomechanical limits still need to be determined.

    ABSTRACT: This study aimed to investigate the impact of preradiation tooth loss in patients with head and neck cancer. Records of 397 (partially) dentate patients who were referred for preradiation oral screening were included. Number and location of teeth lost and occluding pairs lost were determined for different tumor locations. The majority of patients (54%) were affected by tooth loss. Proportion of teeth lost, their location, and proportion of occluding pairs lost were not evenly distributed across tumor locations. The highest proportions of teeth were removed with oral tumors (maxilla: 25%; mandible: 47%). For preradiation preventive extractions only, ie, not taking into account teeth that were lost due to ablative surgery, tooth loss in the mandible was still not evenly distributed across tumor locations, but tooth loss in the maxilla and occluding pairs lost were. Tumor location affects preradiation tooth loss, though this is primarily a consequence of ablative surgery rather than a consequence of preradiation dental extraction decisions. Since patients with oral cavity tumors are affected most by preradiation tooth loss, treatment planning with regard to functional rehabilitation is desirable for this patient group in particular.

    ABSTRACT: The aim of this retrospective cohort study was to evaluate the clinical performance of zirconia-based implant-supported single crowns and fixed dental prostheses (FDPs) made by 15 members of the Italian Academy of Prosthetic Dentistry (AIOP) over a time period of up to 5 years. One hundred thirty-one patients were treated with a total of 210 zirconia-based single crowns and FDPs on implants in anterior and posterior regions. A cohort group with parafunctional habits was compared with patients without parafunctional habits according to the esthetic, functional, and biologic United States Public Health Service criteria modified by the FDI World Dental Federation. The estimated cumulative survival (ECS) and standard error (SE) of all restorations on implants was 91.95% ± 1.39%, and the estimated cumulative success (ECSs) and SE was 88.37% ± 1.72%. The ECS of single crowns and FDPs was 91.25% ± 3.69% and 95.23% ± 2.28%, respectively, and the estimated cumulative success rates were 88.84% ± 2.05% and 87.96% ± 3.16%, respectively. Mechanical failures, including four zirconia core fractures, three hairline cracks, four chippings, and five delaminations of the ceramic veneering material, were recorded during a 1- to 5-year observation period. The odds ratio of 3.39 (95% confidence interval: 1.18 to 9.73) showed a moderate association between parafunction and failure. Zirconiabased implant-supported restorations showed encouraging clinical results over a period of up to 5 years, but more clinical data are needed before these restorations can be considered a viable treatment alternative. Mechanical failures were primarily observed in patients with parafunctions.

    ABSTRACT: This study aimed to compare the viscoelastic properties and antimicrobial activity of a soft liner with and without silver zeolite for a period of 4 weeks. Thirty edentulous patients wearing complete dental prostheses were selected. A uniform space was created in the intaglio surface of their maxillary prosthesis, and a soft liner without silver zeolite (control material: S) was applied. After 28 days, the soft liner was replaced with new soft liner containing silver zeolite (test material: SZ) and worn for another period of 28 days. Viscoelastic analysis was conducted on the prostheses using S and SZ materials for newly formed samples (T0) and on samples collected after the 28-day period (T28). Culture tests were performed on both materials at T28. Statistical analysis was done using Student independent t test. The decrease in elasticity from T0 to T28 was found to be 76.49% and 79.11% and the decrease in viscosity was 76.49% and 80.3% for the S and SZ materials, respectively. Hence, the difference was not significant. The mean colony-forming units (CFUs) of Candida albicans and gram-negative bacteria in the S material at T28 days was 3,150 ± 1,251, whereas that of the SZ material was 1,084 ± 662. There was a statistically significant difference in the mean CFUs between the two groups (P < .05). The addition of silver zeolite to the soft liner improved the antimicrobial activity while not affecting significantly its viscoelastic properties.

    ABSTRACT: This study investigated the positional relation of the commissure line of the mouth to the maxillary first molars. Thirty-five volunteers, 20 to 40 years old, with normal natural dentitions were recruited. Maxillary casts with marks locating the commissure were digitally scanned to measure the vertical distance from the tip to the base of the mesiofacial cusp (CO) and from the tip to the mark (CM). There was no significant difference (t test; P > .05) between the CO (1.61 ± 0.41 mm) and CM (1.14 ± 0.68 mm). The mean distance of the commissure mark from the occlusal plane was 0.78 mm.

    ABSTRACT: The effect of renewing removable dentures on masticatory function was evaluated according to the occlusion offered by different types of mandibular arches. Twenty-eight patients with complete maxillary dentures were subdivided into three groups in terms of mandibular dentition type: dentate, partial denture, and complete denture. The participants were observed before and 8 weeks after maxillary denture renewal. The mandibular denture was also renewed in the partial and complete denture groups. The participants masticated carrots, peanuts, and three model foods of different hardnesses. The particle size distribution of the boluses obtained from natural foods was characterized by the median particle size (d50) in relation to the masticatory normative indicator (MNI). Chewing time (CT), number of chewing cycles (CC), and chewing frequency (CF) were video recorded. A self-assessment questionnaire for oral health-related quality of life (Geriatric Oral Health Assessment Index [GOHAI]) was used. Statistical analyses were carried out with a mixed model. Renewal of the dentures decreased d50 (P < .001). The number of participants with d50 values above the MNI cutoff decreased from 12 to 2 after renewal. Renewal induced an increase in mean CF while chewing model foods (P < .001). With all foods, renewal tended to affect CT, CC, and CF differently among the three groups (statistically significant renewal Å~ group interactions). The GOHAI score increased significantly for all groups. Denture renewal improves masticatory function. The complete denture group benefited least from renewal; the dentate group benefited most. This study confirmed the usefulness of denture renewal for improving functions and oral health- related quality of life.

    ABSTRACT: This survey aimed to review how scientific articles were reported and to describe the types of statistical tests that had been recently and commonly used in The International Journal of Prosthodontics. All 174 articles published in 2012 and 2013 were hand-searched to identify scientific articles (n = 151) and those using at least one statistical test to explore results (n = 111). Editorials, letters, comments, erratum, and award proceedings were excluded. The number and type of statistical tests used within articles were collated, and the 10 commonly used methods were identified and described. Of the 151 scientific articles, 76% (n = 111) used at least one statistical test and 24% (n = 40) used qualitative methods. Up to 10 tests were used per article, with 237 in total, of which 36 were unique. The 10 most commonly used tests were analysis of variance (ANOVA; n = 34), survival analyses (n = 29), Student t test (n = 19), chi-square (n = 19), Mann-Whitney U (n = 14), logistic regression (n = 13), Wilcoxon signed rank (n = 12), Fisher exact (n = 11), log-rank (n = 10), and Cox proportional hazards (n = 8), and they accounted for 71% (n = 169) of all tests used. The vast majority of articles published in recent years in The International Journal of Prosthodontics employed statistical analyses. Across 2 years, nearly 250 tests were completed, including 36 unique tests. Statistical test use was common but diverse.
