This article demonstrates the use of an implant insertion method for the posterior region. Following an atraumatic extraction of a posterior tooth, an immediate implant can be placed at the time of the extraction. A surgical technique that involves the insertion of the implant into the interseptal bone of a multirooted posterior tooth extraction socket in a manner to provide initial stabilization of the implant and partial fill of the extraction sockets is described. Bone graft and a membrane are also required to augment the remainder of the extraction socket and provide maximum bone fill around the implant. The advantages, disadvantages, and indications for the procedure are described.
