New Guidelines for the Treatment of the Alveolar Septum in Immediate Dentoalveolar Restoration Technique Associated with Osseodensification: A Case Series.

Background: Achieving initial implant stability at the molar extraction site can be challenging due to bone width, quality, and anatomical limitations like the maxillary sinus and inferior alveolar nerve. The implant placement should achieve precise centralization with the interradicular septum to facilitate implant stabilization and preservation/regeneration of the alveolar ridge post-extraction with bone grafting. Immediate non-occlusal crown placement aids peri-implant tissue maturation for the desired outcome. This retrospective series introduces guidelines for treating sockets with alveolar septum types. The approach involves immediate dentoalveolar restoration (IDR) and osseodensification (OD) with an autogenous graft for bone preservation.

Methods: A new protocol for the treatment of the molar interradicular septum during immediate implant placement and/or alveolar ridge preservation/reconstruction was applied in 12 cases. Preoperative and postoperative cone-beam computed tomographic examinations were performed. Socket width was measured and compared between timepoints.

Results: The mean preoperative and postoperative (mean, 23.58 ± 9.70 months) socket widths were 9.51 ± 0.40 and 11.16 ± 0.30 mm, respectively (17.35% increase; p <0.05).

Conclusion: IDR with OD is a predictable approach to the treatment of molar sockets during implant placement.
