Evaluation of patterns in mandibular fractures among South Indian patients.

The objective of this study is to evaluate the predicted mandibular fracture pattern among a sample of patients visiting a dental hospital in Chennai, India based on patient demographics. This retrospective analysis involved 46 patients out of which 39 were male and 7 were female who were referred to the Oral Surgery Clinic, Chennai. The medical records and orthopantograms for these 46 patients who received treatment for fractures of the mandible from June 2019- March 2020 were reviewed. Parameters such as age, gender, pattern of distribution, type of mandibular fracture, combination of the fracture and treatment done, were evaluated and assessed by one examiner and reviewed by 2 independent investigators. Data shows that the angle region to be the most common area to be affected (31.67%), accompanied by parasymphyseal region (28.33%), condylar region (13.33%), dento-alveolar region ( 10%), body (8.33%), symphyseal region ( 6.67%) and finally the coronoid region ( 1.67%). Data analysis also revealed that 84.78% of all patients with fractures of the mandible were male and 34.78% of all patients were in the age group of 21-30 years. Most fractures presented with a single fracture site (60.87%), and among combinations of fractures, fractures of parasymphyseal region along with angle region (41.67%) were seen more commonly. Pearson's Chi Square Test was used to determine the association linking the type of mandibular fracture and treatment modality used and p value was < 0.05, which was considered statistically significant. Thus, the patterns of mandibular fractures delineate a significant occurrence of angle fractures among mandibular fractures, commonly seen along with fractures of parasymphyseal region and occurring with a significant male predilection.

Commonly Used Implant Dimensions in the Posterior Maxilla - A Retrospective Study.

Implant therapy is a treatment option to ensure prosthesis survival rate and it is also done as a fixed dental prosthesis for replacing single and multiunit gaps. Posterior maxilla often has insufficient bone quality and quantity; for this reason it makes implant placement challenging in the site. Posterior edentulous maxilla presents special challenges to implant surgeons that are unique to this region compared to other regions of the maxilla. Thus, the aim of this study is to determine the common implant dimensions used in posterior maxilla. Completed case sheets were collected from a private dental hospital software system. Case sheets were taken from June 2019 to March 2020. Data was retrieved and evaluated by two reviewers. The parameters taken were patients, age groups, gender, teeth indicated for implants (maxillary premolars and molars), implant height, and implant width. Two-hundred fifty-four implants have been placed on the posterior maxilla of which 139 were premolars and 115 were molars. There was no statistical significance between the implants placed in both males and females (p value: 0.274). Between the age groups, the highest number of implants was seen in 41-60 years (n = 146) followed by 17-40 years (n = 78) and finally > 61 years (n = 30). The p value was 0.000, which was statistically significant. Various implant sizes for posterior maxilla have been introduced due to its challenging site. Thus in our study, we can see there is a difference in sizes for premolars and molars. Implant dimensions with increased height are used in the premolars compared to the molars. Implant dimensions with increased width are used in the molars compared to the premolars. In general, implant width and implant height can range from 3.6 to 4.5 mm and implant height ranging from 9.50 to 12.00 mm.

Survival of Implant-Supported Full-Mouth Rehabilitation among Patients Reporting to a Private Dental Institution.

Full-mouth rehabilitation (FMR) is of increasing importance, as it is through this procedure that patients with dentitions which are in different stages of degeneration or loss can be restored to functional dental health. To identify the survival of implant supported fmr among Chennai population. The participants were the patients who reported for FMR procedure between June 2019 and March 2020 to Saveetha Dental College and Hospital Chennai, the patients were recalled at regular intervals and the survival of the treatment was assessed. The periodontal status was good among 42.3% the occlusion was satisfactory among 69.23% and the esthetics was good in 34.86% of patients on evaluation of the FMR. From the present study we can conclude that the overall survival rate of implant supported among south Indian population is found to be satisfactory and further research must be done in this field to increase the survival rate.

Requirement of Osteoplasty in Dental Implant Surgery-A Retrospective Analysis.

Osteoplasty is a surgical procedure for reshaping or recontouring bone. As dental implants are the most commonly preferred treatment for prosthetic rehabilitation, adequate bone height and width are important prerequisites for a successful implant. There is continuous resorption of the alveolar crestal region after extraction of the tooth, which may form sharp edges or sharp bony margins. Osteoplasty is required in such cases to remove the sharp bony margins and flatten the alveolar bone so as to provide increased stability of the implant in the socket. The aim of this retrospective, university-based study was to assess the requirement of osteoplasty in dental implant surgery. Data of patients who underwent implant surgery were collected. A total of 554 patients (331 males and 223 females) with 1,044 implant sites were included. The data were further sorted with respect to age, gender, implant site, and requirement of osteoplasty, and analyzed using SPSS software. The mean age of the patients was 42.70 ± 13.03. A chi-square test assessed association and correlation. The requirement of osteoplasty was higher in the mandibular posterior region (42.2%) than in any other clinical site. In comparison with gender, the requirement was significantly higher in males than in females.

Implant Dimensions Commonly Used for the Posterior Mandibular Region among Patients Visiting a Dental Institution in Chennai: Retrospective Study.

Rehabilitation with dental implants is, without doubt, an ordained technique. The clinical utilization of dental implants has accelerated in recent years, and new applications continue to emerge. This retrospective study aims to report the implant dimensions commonly used for the posterior mandibular region. It was done at Saveetha Dental College and Hospitals. A total of 391 patients with 670 implant sites within the 20-80 age group who had undergone implant placement were included in the study. The case sheets of patients were obtained from patient information archives. The data on each patient were obtained and tabulated. Out of the 391 patients, 52.2% were males and 47.8%% were females; 33.3% belonged to the < 35 age group, 34.5% belonged to the 35-46 age group, and 32.2% belonged to the > 46 age group. The prevalence rate of replacement for mandibular molars was 85.2%; for mandibular premolars, 14.8%. Implant dimensions for posterior mandibles were found to differ based on gender and age group. Males had a greater mean implant width compared to females. Implant dimensions with increased height were used in premolars compared to molars. Implant dimensions with increased width were used in molars compared to premolars. In general, implant width ranged from 3.3 to 5 mm and implant height ranged from 9.5 to 13 mm in the mandibular molar region.
