Comparison of Osteoblastic Activity Around Endosseous Implants Placed with Osseodensification and Adaptive Osteotomy Techniques--A Split-Mouth Prospective Case-Control Study

Abstract

Purpose: To compare the osteoblastic activity around dental implants placed via adaptive osteotomy and osseodensification techniques using bone scintigraphy in human subjects. Materials and Methods: A single-blinded, split-mouth design was conducted on two sites in each of the 10 subjects, with the adaptive osteotomy (n = 10) and osseodensification (n = 10) techniques for implant placement performed on either side of the D3-type bone in the posterior mandible. All participants were subjected to a multiphase bone scintigraphy test on the 15th, 45th, and 90th days after implant placement to evaluate the osteoblastic activity. Results: The mean values obtained on the 15th, 45th, and 90th days in the adaptive osteotomy group were 51.14% ± 3.93%, 51.40% ± 3.41%, and 50.73% ± 1.51%, respectively, while the osseodensification group values were 48.88% ± 3.94%, 48.78% ± 3.38%, and 49.29% ± 1.56%, respectively. The intragroup and intergroup analyses revealed no significant difference between the mean values of the adaptive osteotomy and osseodensification groups on the tested days (P > .05). Conclusions: Osseodensification and adaptive osteotomy techniques improved primary stability of D3-type bone and accelerated the osteoblastic activity after implant placement, with no superiority of one method over the other.
