Partial Extraction Therapy (Part 2): Complication Management in Full-Arch Dental Implant Therapy

Int J Periodontics Restorative Dent. 2023 Sep-Oct;43(5):570-577. doi: 10.11607/prd.6127.

Abstract

Partial extraction therapy (PET) is a group of surgical techniques that preserve the periodontium and peri-implant tissues during restorative and implant therapy by conserving a portion of the patient's own root structure to maintain the blood supply, derived from the periodontal ligament complex. PET includes the socket shield technique (SST), proximal shield technique (PrST), pontic shield technique (PtST), and root submergence technique (RST). Although their clinical success and benefits have been demonstrated, several studies report possible complications. The focus of this article is to highlight management strategies for the most common complications associated with PET, including internal root fragment exposure, external root fragment exposure, and root fragment mobility.
