Transmucosal Collar
The portion of a dental implant or abutment that passes through the soft gingival tissue to emerge into the oral cavity.
Full Definition
The transmucosal collar is the segment of an implant system — which may be part of the implant body itself or a separately attached abutment component — that traverses the peri-implant mucosa and is exposed to the oral environment. Its height, shape, and surface texture are critical editorial considerations because they affect how clinicians describe tissue management protocols. Editors must distinguish between the transmucosal collar of a one-piece implant and that of a two-piece system. Incorrect description of collar height can affect the clinical sense of a surgical protocol document. The term is distinct from the healing abutment, which is a temporary component serving a similar spatial role.
Usage
Usage note: Do not conflate with 'healing abutment'; the transmucosal collar is a structural zone, not a removable component.
In Context
- "The 2 mm transmucosal collar was selected to accommodate the patient's tissue thickness and avoid subcrestal positioning of the polished zone." — Surgical protocol report
- "Authors should specify whether transmucosal collar height measurements are taken from the platform level or the crestal bone." — Journal manuscript editorial note
