Transgingival Height
The vertical dimension of an abutment or implant collar that passes through the gingival tissue, connecting the subgingival fixture to the supragingival prosthetic component.
Full Definition
Transgingival height, also called gingival height or mucosal height, describes the portion of an implant component that traverses the soft tissue from the crestal bone level to the gingival margin. Selecting the correct transgingival height is essential for establishing an appropriate emergence profile and avoiding compression or tension on the peri-implant soft tissues. In prosthetic documentation and implant manufacturer catalogues, transgingival height values are expressed in millimetres and must correspond to the measured tissue thickness at the implant site. Editors should not conflate this with implant depth or crown height.
Usage
Usage note: Do not confuse with 'crown height space', which measures the total vertical distance available for the prosthetic crown.
