A Prospective Study of Bone Augmentation Techniques in Extraction Sockets and Implant Surface Textures

Tooth extraction is often associated with resorption of the alveolar ridge height and width and with compromised soft tissue contours. A variety of methods have been proposed to overcome varied patterns of post-extraction healing.

An increasingly common practice combines skilled surgical technique with post-extraction site grafting utilizing both natural and synthetic bone-graft materials. These procedures are thought to retard resorption of the socket volume while lending some control over bone-fill - thereby preserving the integrity of the alveolar ridge for future reconstruction with dental implants.

Limited evidence-based data exist to support a variety of bone-graft materials including grafts enriched with autologous platelet-rich plasma(PRP)and grafts enriched with recombinant human platelet-derived growth factors(PDGF). Despite emerging clinical acceptance the most efficacious intervention remains undetermined.

In an effort to establish clinical evidence, this study will assess the efficacy of ridge preservation using three different bone grafting applications in post-extraction sockets compared to extraction alone.

The study will also asses longitudinal success of restoring the study sites with dental implants. Two innovative dental implant designs will be used in the study; an implant with a resorbable blast textured(RBT)surface and an implant with a laser thread-textured (LTT)surface.
