A Modified Socket-Shield Technique: Simplifying the Root Sectioning Process.

Abstract

Socket wall resorption leading to a loss of surrounding bone following tooth extraction has been documented in the dental literature. The use of various socket-shield techniques has been suggested as a solution to this issue. In these approaches, the tooth root is sectioned in two, and the coronal two-thirds of the buccal root is preserved in the socket. This allows the periodontium along with the bundle and buccal bone to remain intact, thus preventing or minimizing bone remodeling. According to the literature, this procedure is highly technique sensitive, especially when it comes to sectioning the root. Additionally, the procedure requires significant time, and several complications may occur, such as fenestration or luxation of the remaining root, requiring its complete extraction. This case report presents a modified socket-shield technique using a trephine bur guided by a computer-designed surgical guide to simplify root sectioning, thus reducing surgical time while increasing predictability of the outcome.
