GPT1 - Have You Heard about Partial Extraction Therapy? Now is the Time!

In implant dentistry, collapse of the buccopalatal dimension of an extraction socket is a known sequela. Multiple ridge preservation techniques to include bone and soft tissue grafting have been utilized over the years. Although these techniques can be successful, loss of buccal contour is a common finding even after one year in function. Partial extraction therapy (socket shield, pontic shield and root submergence) is a technique aimed at addressing this collapse. The success of the procedure is thanks to the planned retention of a small fragment of buccal root attached to the bone. This root attachment has been shown to maintain the periodontal ligament and blood supply and, as a result, the thin bundle bone. A critical factor in prosthetic rehabilitation is the correct management of the emergence profile and the abutment crown complex. This also is paramount in socket shield. The presentation will familiarize the OMS resident and clinicians with this partial extraction therapy technique and when it is necessary. In addition, attendees will learn how to digitally plan and perform the surgical and critical subgingival prosthetic phase.
