Immediately placed implants using simvastatin and autogenous tooth graft combination in periodontally compromised sites: a randomized controlled clinical trial.

OBJECTIVES

The present study aimed to assess clinically and radiographically the usage of autogenous tooth bone graft (ATBG) combined with and without Simvastatin (SMV) around immediately placed dental implants in periodontally compromised sites.

METHODS

Thirty-nine patients required a single extraction of periodontally compromised tooth were divided into three groups (13 patients each). Group I received immediate implant placement (IIP) without grafting. Group II received IIP with ATBG filling the gap around IIP. Group III received SMV gel mixed with ATBG around IIP. Radiographic changes were reported at the baseline, 6-, and 12-months post-surgery.

RESULTS

All implants achieved the success criteria with no complications. At 6- and 12-months post-surgery, group III showed a statistically lower mean ridge width loss compared to Group I and Group II (P < .001). Group II revealed less reduction in the mean alveolar ridge width compared to group I (P < .001). Group III showed a statistically significantly less MBL loss than group I and group II (P < .001). All groups showed a statistically significant increase in BD gain compared to baseline (P < .001). Group III showed statistically significant high BD compared to group II (P < .001). Group II showed statistically significantly higher mean BD gain than that of group I (P < .001).

CONCLUSION

SMV combined with ATBG boosts the hard tissue parameters around dental implants over ATBG alone. Clinical trial registration was on August 1, 2021 (NCT04992416).

CLINICAL RELEVANCE

ATBG with SMV in periodontally compromised sites could improve implant osseointegration and promote favorable changes in peri-implant tissues.
