Purpose: The aim of this study is to evaluate bone change around the implant in patients who underwent alveolar ridge preservation for implantation in the posterior teeth using radiographic data measuring changes of mesial, distal crestal bone level according to post-implantation, post-final prosthesis delivery and follow-up periods.

Materials and methods: In total, 36 implants were placed in 32 patients. The mesial and distal crestal bone level of all the areas where alveolar ridge preservation was performed uses panoramic images taken post-implantation, post-final prosthesis delivery, and follow-up period each was measured and evaluated as a vertical value. The following factors were analyzed: associations between changes of crestal bone level and factors (e.g., age, sex, systemic diseases, dentist, implant location, tooth, bone type, membrane). The statistical analysis was performed using the mean, standard deviation and independent t-test, paired t-test (P < .05).

Results: Analysis of crestal bone level differences between periods shows statistically significant differences (P < .05). There was no statistically significant difference when the changes of crestal bone level between post-implantation, post-final prosthesis delivery and follow-up periods were correlated with each factors.

Conclusion: After alveolar ridge preservation, bone around the implant remained stable during the maintenance period without being affected by the patient and surgical factors, and alveolar ridge preservation is considered a clinically usable procedure.
