EVALUATION OF THE STABILITY OF IMMEDIATE IMPLANT PLACEMENT IN MANDIBULAR MOLAR INTER-RADICULAR SEPTUM USING OSSEODENSIFICATION TECHNIQUE (CLINICAL TRIAL)

Abstract

BACKGROUND: Immediate implant placement (IIP) is a valid technique for replacement of badly destructed teeth with fewer surgical procedures and increased levels of patient comfort. OBJECTIVES: To evaluate the stability of immediate implant inserted in mandibular molar inter-radicular septum using osseodensification technique. MATERIALS AND METHODS: Ten patients with ten lower molars to be extracted were chosen according to a list of inclusion and exclusion criteria. The participants undergone atraumatic tooth extraction, then the inter-radicular septum was densified using densah burs, immediate implants were installed, followed by bone graft placement in the gap between the implant and the socket walls, and a healing abutment was placed. Interrupted sutures were then placed around the healing abutment. Assessment included measurements of implant stability using the Osstell device immediatel after implant placement and after 3 months post-operatively. Also, bone density surrounding the implant was measured pre-operatively, immediately post-operatively and after 3 months post-operatively. RESULTS: The results revealed that Secondary Stability (ISQ) three months postoperatively with a mean±SD. of 76.20±5.43 was statistically significantly increased compared to Primary Stability (ISQ) immediately after implant insertion with a mean±SD. of 65.20±4.96( p <0.001). The bone density was significantly increased immediately postoperatively and three months postoperatively compared with preoperatively ( p <0.001, p =0.002; respectively). CONCLUSION: Osseodensification using densah burs was found to be an efficient procedure in increasing stability of immediately placed dental implants in molar inter-radicular septum.
