Mucosal Thickness
The measured vertical dimension of the soft tissue overlying the alveolar bone at a proposed or existing implant site, a parameter that significantly influences peri-implant health and aesthetic outcomes.
Full Definition
Mucosal thickness refers to the distance between the surface of the peri-implant or alveolar mucosa and the underlying bone, typically measured in millimetres using an ultrasonic device, periodontal probe, or CBCT analysis. Thicker mucosa (generally ≥2 mm) is associated with greater stability of the peri-implant soft-tissue margin and reduced crestal bone loss. The parameter is particularly relevant when selecting transmucosal component heights and designing the emergence profile. In clinical documentation, editors frequently encounter this term in the context of pre-surgical planning records and outcomes reporting. It should not be confused with keratinised mucosa width, which describes horizontal soft-tissue dimension rather than vertical depth.
Usage
Usage note: Distinguish carefully from 'keratinised mucosa' (a tissue quality descriptor) and 'tissue biotype' (a classification rather than a direct measurement). Always specify the unit of measurement (mm) in clinical documents.
In Context
- "A mucosal thickness of less than 2 mm was recorded at the implant site, prompting a connective tissue graft prior to final restoration." — Clinical case report
- "The operative note incorrectly recorded 'mucosal width' where 'mucosal thickness' was the intended measurement; the editor queried the discrepancy." — Editorial query log
