IObjective: The aim of this study was to assess the influence of surgical flaps over bone formation around implants. Methods: Seven mongrel dogs had four mandibular pre-molars extracted and four immediate implants placed. The experimental groups were divided into G1 (flapless) and G2 (full-thickness flap), totaling 14 implants in each group. After four months, samples were collected and histomorphometric analysis was carried out with a view to assessing buccal bone-to-implant contact (BIC), total BIC, buccal area, and total area of all implants. For intergroup statistical analysis, Mann-Whitney test was applied (p < 0.05). Results: The group comprising implants without flap elevation had better BIC rates, both buccal and total BIC, than the flap elevation group. Additionally, data yielded better results in favor of the group without flap, which was statistically significant, particularly with regard to bone formation on the buccal surface of implants. Conclusion: The flapless surgical technique produces favorable eŠects on bone formation around implants.
