Abstract
Immediate implant placement is the current modality to provide implant placement following tooth extraction. Immediate implants in posterior multirooted teeth pose challenges in terms of proper angulation and parallelism. Engaging the inter-radicular septal bone provides the advantage of primary stability. Osteotomy site preparation through the septal bone with roots of the natural teeth as a guide provides a precise osteotomy procedure with minimal collateral damage to the adjacent area. This case series aimed to assess the success of immediate implant placement in posterior multirooted teeth using the residual roots as anatomical guides. Three cases of grossly decayed posterior teeth were treated with immediate implant placement. The osteotomy site was prepared using the roots as surgical guides. Implant stability was assessed by resonance frequency analysis (RFA) immediately after placement and 6 months post-op. Healing was uneventful in all cases. Optimal implant stability quotient (ISQ) values of above 70 were achieved, which are suggestive of good primary stability. The desired angulation and parallelism were obtained by utilizing the residual roots as anatomical guides. Six months post-surgically, the patient presented with healthy peri-implant tissue and successful osseointegration. Root-guided implant placement is a novel technique wherein residual roots provide a surgical guide for the placement of immediate implants in multirooted posterior teeth.
