Aims and Objectives : To assess the efficacy of flapless implant surgery on soft-tissue profile and to compare the clinical outcomes of flapless implant therapy on immediate loading (IL) implants to delayed loading (DL) implants. Materials and Methods : The study sample consisted of 20 patients who were partially edentulous in the anterior maxillary region. They were divided into two groups. In group I (IL) 10 implants were placed and immediately provisionalized and restored with a metal ceramic crown on the 14th day. In group II (DL) 10 implants were placed and loaded after 4 months. Single-piece implants were used for the IL group and two-piece implants were used for the DL group. All soft tissue parameters i.e., modified plaque index (mPI), modified bleeding index (mBI), papillary index (PPI), marginal level of soft tissue (ML) and width of keratinized mucosa (WKM) were recorded at baseline, Day 60, Day 120 and Day 180. Results: The success rate in group I was found to be 80%, which was lower than the success rate in group II which was found to be 90%. On comparison, there is no statistically significant difference in success rate between the two study groups. There was no statistically significant difference between the groups over time in parameters like mPI, mBI, ML and WKM. The mean PPI score in group II showed a significant increase from when compared to group I. Conclusion: The results of this study indicated that flapless implant surgery using either immediately loading implants or DL implants, demonstrate enhancement of implant esthetics.

Introduction: Adjunctive therapy with locally delivered antimicrobials has resulted in improved clinical outcomes. The aim of this study was to evaluate the efficacy and safety of locally administered minocycline microspheres (Arestin TM ) in the treatment of chronic periodontitis. Materials and Methods: A total of 60 sites from 15 patients in the age group of 35-50 years, who had periodontal pockets measuring 5-8mm and had been diagnosed with chronic periodontitis, were selected for the study. The selected groups were randomly assigned to either the control group (group A) or the treatment/test group (group B). Only scaling and root planing were done at the base line visit for the control sites followed by local application of Arestin™ (1mg). Clinical parameters such as plaque index, gingival index, and gingival bleeding index were recorded at baseline, day 30, day 90, and day 180 in the selected sites of both the groups. Probing pocket depth also was recorded at baseline, day 90, and day 180 for both the groups. Results: A statistically significant reduction was observed in both groups. Group B showed better results than Group A and these differences were statistically significant. Conclusion: The results of this study clearly indicate that treatment with scaling and root planing plus minocycline microspheres (Arestin™) is more effective and safer than scaling and root planing alone in reducing the signs of chronic periodontitis.
