Socket Shield Technique
An immediate implant placement approach in which a portion of the root is intentionally retained within the buccal socket wall to preserve the periodontal ligament and prevent buccal bone resorption.
Full Definition
The socket shield technique (also called root membrane technique or partial extraction therapy) involves retaining the buccal fragment of a tooth root at the time of implant placement, rather than performing a conventional complete extraction. The retained root shield preserves the buccal bundle bone and periodontal ligament, preventing the resorptive changes that normally follow extraction. This technique is particularly significant in the anterior aesthetic zone. Editors should note that 'socket shield' is typically written as two words (not hyphenated) when used as a noun phrase, but hyphenated as a compound modifier ('socket-shield technique'). The term should not be confused with socket preservation, which is a separate augmentation procedure performed after extraction.
Usage
Usage note: Hyphenate as a compound modifier before a noun: 'socket-shield technique'. Do not conflate with socket preservation (a grafting procedure).
