In vivo Comparison of Crestal Bone Heights Following Implant Placement with “Flapless” and “Flap” Techniques in the Sites of Early Loaded Implants

PURPOSE: The purpose was to evaluate the difference in crestal bone loss (CBL) around implants with flap and flapless methods followed by early loading. MATERIALS AND METHODS: Twenty implants were placed in twenty patients – ten using flap and ten using flapless techniques. The difference in CBL was measured on standardized digital periapical radiograph taken at 0 week, 6 weeks, 12 weeks, and 6 months. RESULTS: The present study showed the mean CBL on proximal surfaces when evaluated at intervals of 0 week, 6 weeks, 12 weeks, and 6 months for flapless method was significantly lower than with flap method the values of which were +0.07 mm against +0.26 mm on mesial side and +0.15 mm against +0.33 mm on distal side at 6 months. CONCLUSION: The flapless approach is a predictable procedure when patient selection and surgical technique are appropriate, and results in lesser CBL.
