Background: Implant site development can be effective in minimizing postextraction alveolar ridge resorption in the esthetic region. Microsurgical approach has demonstrated substantial improvement in soft-tissue architecture. Aim and Objectives: The aim of the present study was to evaluate and compare the efficacy of microsurgical technique with conventional one for implant site development utilizing biphasic hydroxyapatite/beta-tricalcium phosphate bone graft substitute and collagen membrane. Materials and Methods: Thirty extraction sites were planned for implant placement and randomly divided into control (macrosurgical/conventional) and test (microsurgery) sites. Clinical measurements were recorded at four different points of extraction socket, i.e., mesiobuccal, midbuccal, distobuccal, and midlingual/palatal at baseline, 3, 6, and 9 months. Postoperative neovascularization at control and test site was evaluated by ultrasound Doppler flowmetry at baseline, 10th day, and 1 month. Radiological assessment of bone density (Hounsfield units) was measured at control and test sites at baseline, 6 and 9 months by computed tomography. Data was subjected to statistical analysis. Results: Significant socket fill at all the four different sites was observed and found to be statistically significant at test as compared to control group with better tissue contour after 3, 6, and 9 months. Test group demonstrated better neovascularization (P < 0.05) with significantly higher bone density (P = 0.000) at different time intervals. Conclusions: The results indicate that the augmentation of extraction sockets, not only improved the quality of bone in both the techniques but the utilization of microsurgical instruments and microsutures under magnification definitely enhanced the quality of soft tissues which is imperative for successful implant placement and its survival.
