Maintaining Bone and Soft Tissue Morphology in Full Arch Cases. The Partial Extraction Therapy Paradigm – Richard Martin, DDS

Richard Martin, DDS
Collapse of the buccopalatal dimension of an extraction socket in implant dentistry 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 1 year in function. Ultimately this can lead the hygiene compromise and periimplantitis. Partial extraction therapy (PET) (socket shield, pontic shield and root submergence), specifically the socket shield is a technique aimed at addressing this collapse. The success of the procedure is due to intentional retention of small fragment of buccal root attached the bone. This root attachment has been shown to maintain the periodontal ligament (PDL)j and blood supply and as result the thin bundle bone. Utilization if the PET in full arch implant reconstruction has shown to be effective.
