Purpose The goal of this study was to evaluate the incidence of postoperative wound infection and timing of mandibular third molar removal in bilateral sagittal split osteotomy (BSSO). Materials and methods This wis a prospective, single-blinded, randomized, split-mouth clinical trial. All patients were divided into two groups: Group I, where pre-operative removal of the third molars were done 6 months prior to BSSO and Group II, where intra-operative removal of contralateral third molars were done for the same patients during the osteotomy. The primary outcome variable studied was postoperative infection rate and the secondary outcome variable was bad split during BSSO. Results Among the seventy five patients (150 sites), one site in group II developed infection whereas none of the sites in group I developed infection (p = 1.000). No sites had bad split in both the groups. Conclusion The results from the present study show that there is no difference between the presence or absence of mandibular third molars on post-operative wound infection following bilateral sagittal split osteotomy, and the authors hence suggest removing third molars during BSSO for patient comfort.

Aim The aim of the current study is to assess and evaluate the effectiveness of concentrated growth factors on wound healing after implant placement procedures. Methodology Twenty-four patients who underwent implant placement were included in the study and were divided into two groups (group 1 = non-CGF group; group 2 = CGF group). Conventional implant placement was done in both the groups followed by placement of CGF membrane and closure using 3-0 silk in the CGF group and only closure using 3-0 silk sutures in the control group. The patients were asked to report on the 3rd and 7th day respectively and the wound healing was assessed using an early wound healing index given by Lorenzo Marini. Statistical analysis Shapiro-Wilk test was used to test the normality of the test, which was found to deviate from normal distribution and hence Mann-Whitney U test was employed to evaluate the statistical significance of the two independent samples. Results The mean ± SD was found to be 6.17 ± 2.04 for the control (group 1) and 5.67 ± 0.51 for CGF group (group 2) on the 3rd day. The mean and SD of control group and test group on the 7th day was 7 ± 1.55 and 9.33 ± 1.63, respectively. The difference between the groups on the 7th day was found to be statistically significant (P value Conclusion Concentrated growth factor application had positive effects on surgical wound healing after implant placement.

Dental implants provide a strong foundation for fixed or removable prosthetic teeth that are made to match natural dentition. It has become an ideal method of oral rehabilitation after missing natural dentition has been recognised as a reliable tool for dental reconstruction and aesthetics. Marginal bone loss is characterized by a reduction in bone loss is characterized by a reduction in bone level both vertically and horizontally. The levels at which dental implants are placed include sub-crystal, equi-crestal, and supra-crestal. The crestal levels affect bone height significantly. Failure to do so will lead to peri-implant bone loss which will affect the implant function and ultimately implant failure. A retrospective study was conducted based on a university setting. 615 patients with 1141 implant sites were reviewed from June 2019 to March 2020. Excel tabulation and SPSS analysis were done for data analysis. There was a statistically significant difference between the variables that included tooth region, crestal relation and site (jaw)—[p-value

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 the35 age group, 34.5% belonged to the 35-46 age group, and 32.2% belonged to the46 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.

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.

The aim of this retrospective study was to identify the significant risk factors that contribute towards postoperative infection in patients recovering from orthognathic surgery. Retrospective records of 522 patients who underwent orthognathic surgery over 9 year period were evaluated for postoperative infection within 3 months of surgery and after 3 months of surgery. The variables of interest included age, gender, habits like smoking and alcohol consumption and incidence of postoperative infection. The overall infection rate was 4.60%. Patients who underwent bilateral sagittal split osteotomy to advance the mandible had an infection rate of 10.4%. Statistically significant predictor variables (P
