Foundation of the osseointergrated prosthesis on the compromised remaining alveolar bone

Tooth loss is inevitably followed by relevant bone loss. Careful volumetric evaluation of the residual bone is the initial step in treatment planning the implant supported reconstruction. Utilizing the existing limited volume of the remaining bone for supporting the osseointegrated prosthesis, may reduce the need for additional preparatory bone augmentation surgical procedures.

As long as the preoperative soft-tissue architecture of a periodontally or endodontically terminal tooth in the esthetic zone is considered acceptable, the flapless immediate extraction implant placement can result to the preservation of the original immergence architecture. The primary stability is secured by inserting the implant in the remaining sound bone by avoiding the defect area.  Additional osseo-conductive inorganic substance is applied in the defect area to provide adequate mechanical and biologic soft-tissue support.

Rehabilitation of the atrophic posterior maxilla can be accomplished by implant insertion simultaneously with closed or opened sinus floor elevation. Moreover, tuberosity/pterygoid Implants have also been applied as a successful alternative approach. On the other hand, reconstruction of the posterior atrophic mandible can be achieved by avoiding the mandibular nerve by deviating the implant insertion lingually or buccally on the cortical bone of the internal or external oblique line.
