Mucosal Margin
In implant dentistry, the soft-tissue border surrounding a dental implant, analogous to the gingival margin around a natural tooth.
Full Definition
The mucosal margin is the apical boundary of the peri-implant mucosa as it contacts the implant or abutment surface. It serves as the reference point for measuring mucosal recession and peri-implant probing depth in clinical studies. Editors working on implant research should verify that authors consistently use 'mucosal margin' for implant sites and 'gingival margin' for natural teeth, as conflating the two terms introduces anatomical imprecision. The mucosal margin position can change over time due to bone remodelling or soft-tissue alterations, and longitudinal changes should be reported with appropriate measurement units. Photographic or digital assessment methods used to record the mucosal margin level should be described in the methods.
Usage
Usage note: Use 'mucosal margin' specifically for implant sites; 'gingival margin' is reserved for natural tooth anatomy. Using the two terms interchangeably is a common and significant editorial error in implant research.
