Abstract
Objective: To evaluate the predictability and success rate of implants installed in extraction sites, where the Guided Bone Regeneration (GBR) technique for bone preservation and implant placement was performed. Methods: This is a retrospective study, which included medical records of patients from the clinic of the Specialization in Implantology course from the educational institution, who underwent GBR in the tooth socket with indicated extraction, who delivered the tomographic exams, and had implants installed in these places, from 2007 to 2016. Forty-two participants were included in the research, totaling 55 sites divided into two groups: maxilla and mandible. Results: Two cases (3.7%) of non-bone formation were found after GBR, in the posterior region of the maxilla, with a success rate of 96.3% for predictability of implant placement in GBR sites. Of the 53 implants installed where there was sufficient bone formation, 3 (5.7%) did not return to the clinic and, therefore, 50 were evaluated, with 48 presenting clinical osseointegration with a success rate of 96%. Conclusion: There is predictability of GBR procedures in post-extraction sockets for the installation of osseointegrated implants.
