Abstract

Purpose: This study aimed to evaluate the effect of Osseodensification and conventional ridge splitting techniques on bone density and implant stability in the posterior region of the mandible. Subjects and Methods: Twelve patients, with horizontal ridge deficiency, who required fixed prosthetic rehabilitation via dental implants were included in our study. They were divided into two equal groups; Group1: implants were inserted in edentulous posterior sites that were expanded by Osseodensifing (Densah) burs. Group2: implants were inserted in edentulous posterior regions that had been expanded by ridge splitting technique, followed by the application of PRF membrane. The total numbers of inserted implants were 24. Implant stability quotient (ISQ) was checked by a resonance frequency analysis system (Osstell device), immediately and at 6 months postoperative. In addition, CBCT was used to evaluate bone density, preoperative, immediately, and after 6 months. Results: In each group, there was a significant difference between the immediate and 6-month ISQ records; However, no statistically significant difference was observed between the two groups regarding the ISQ values. In bone density, there was a statistically significant difference between preoperative and immediate measures in each group, but no statistically significant difference was observed between the two groups. Conclusion: Densah burs and ridge splitting techniques provide well-accepted initial stability for immediate implant placement with an increased bone density over time.
