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

Achieving initial implant stability at a molar extraction site can be challenging due to the bone width and quality, as well as 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 postextraction alveolar ridge preservation/regeneration with bone grafting. Immediate nonocclusal crown placement aids peri-implant tissue maturation for the desired outcome. This retrospective series introduces guidelines for treating sockets based on alveolar septum types. The approach involves immediate dentoalveolar restoration (IDR) and osseodensification (OD) with an autogenous graft for bone preservation. 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 CBCT examinations were performed. Socket width was measured and compared between timepoints. At the follow-up (mean: 23.58 ± 9.70 months), the mean preoperative and postoperative socket widths were 9.51 ± 0.40 mm and 11.16 ± 0.30 mm, respectively (17.35% increase; P < .05). IDR with OD is a predictable approach to treat molar sockets during implant placement.
