A 3-Year Prospective Clinical Study to Evaluate the Outcome of Single-Piece Implant-Prosthetic Complex after Immediate NonFunctional Loading in the Maxillary Anterior and Mandibular Posterior Areas in Varied Bone Densities.

Context: There is limited evidence on the outcome of single-piece implant-prosthetic complex after immediate nonfunctional loading in varied bone densities. Aim: The aim of this study was to report the outcome of single-piece implant-prosthetic complex with a novel cervical platform design in the anterior and posterior jaws 3 years after loading. Setting and Design: Prospective clinical study. Materials and Methods: The present study included placement of 90 single-piece implants in the anterior and the posterior jaws in varied bone densities. After immediate loading, survival and marginal bone loss was recorded at regular intervals. Statistical Analysis: Independent sample t-test and paired t-test were done (P = 0.05). Results: Group I, annual marginal bone loss at the end of one, 2 and 3 years was 0.21, respectively, in both bone densities. Group II, annual marginal bone loss in D2 regions was 0.75,0.38 and 0.18; 0.64, 0.28 and 0.18 in D3 regions at the end of 1, 2, and 3 years, respectively. Group I showed no statistically significant difference in marginal bone loss between D2 and D3 bone annually in contrast to Group II. Intragroup comparisons of mean between baseline and various time intervals showed statistically significant bone loss in both bone densities. Conclusion: Three years after loading, single-piece implants with the novel cervical platform design provided survival rates of 93% in the maxillary anteriors and 91% in the mandibular posteriors. D3 bone showed more marginal bone loss than D2 bone.

A 3-year prospective cohort study on mandibular anterior cantilever restorations associated with screw-retained implant-supported prosthesis: An in vivo study.

Aim: The aim of this study is to evaluate the survival of single implant supported cantilever prosthesis (ISCP) replacing missing two adjacent natural teeth in the anterior mandible. Settings and Design: In vivo - Prospective cohort study. Materials and Methods: Thirty patients with missing both mandibular central incisors were selected. A single implant was used to replace the missing teeth and restored with cantilever screw-retained prosthesis. Twenty-two patients were followed for 3 years for the implant and prosthetic success. Statistical Analysis Used: Weibull test for survival probability. Results: Survival probability of the ISCP for the first 100 days was found to be 97.55%, for 200 days, it was 71.4%, for 250 days, it was 46%, and for 365 days, it was 3.9%, i.e., 20 prosthesis had screw loosening after prosthetic loading. However, it increased to 95.2% at the end of 3 years. Conclusion: Screw-retained ISCP developed early technical complications. After prosthetic loading, the survival probability of the screw-retained ISCP was very low (3.9%) at one year, which increased to 95.2% after retightening and retorquing of the abutment screw, porcelain repair and conformation of the tongue to the prosthesis. The most common prosthetic failure was screw loosening (81%), followed by porcelain fracture (14.3%), and implant survival of 95% at the end of three years.

Awareness and management of peri-implantitis and peri-mucositis among private dental Practitioners in Hyderabad - A cross-sectional study.

BACKGROUND: Implant therapy, in India, has flourished in recent years and is being practiced widely by many dental practitioners today. Along with the increasing number of implants being placed today, there has also been a constant rise in the number of complications associated with it. OBJECTIVES: The aim of this study is to evaluate the knowledge and awareness of implant placement and management of peri-implant diseases among dental professionals. MATERIALS AND METHODS: A total of 568 dental practitioners were approached with a questionnaire for collecting data related to demographic details, experience, and knowledge about implant placement and management of its complications. Of these, only 262 were included as part of the statistical analysis. This data collected were compiled and analyzed using descriptive statistics. RESULTS: Results showed that most dentists who participated in this study have adequate knowledge about etiological factors and its management. Those who acquired implant skills through sources that are not in accordance with accepted standards had unsatisfactory knowledge and practice behavior. CONCLUSION: The awareness and knowledge regarding the implant procedures and their complications such as peri-implant mucositis and peri-implantitis were higher in self-trained dentists and by dentists who are practicing for >10 years and calls for updating of knowledge.
