Abstract

A method for preserving the alveolar ridge surrounding a presently extracted root socket by backfilling the socket with bone graft material and installing an implant in the root socket area either immediately before backfilling or after backfilling and a delay in which new bone is allowed to grow into the bone graft material. In one embodiment, the dental implant is installed apically into the root socket immediately following root extraction. The open area of the root socket surrounding the implant is then backfilled with bone graft material immediately after implant placement. The implant is preferably a threaded implant (but it can be a cylinder-type) which is placed approximately three to six millimeters apically to said root socket. The bone graft material comprises synthetic bone alloplast such as Bioplant.RTM. HTR.RTM. and is hydrated using the patient's own blood obtained from the patient's bleeding extraction socket after penetration but prior to insertion of the bone graft material and the implant into said root socket. As an alternate embodiment, the presently extracted root socket is filled with bone graft material and primary or non-primary closure of the extraction site is performed. Bone-growth is promoted in the root socket by the bone graft material for 2-12 months. Then, after sufficient bone growth has been promoted, an implant is installed in the extraction site area in the normal manner.
