Periodontal Phenotype
A combined assessment of gingival tissue characteristics (thickness, width of keratinised tissue) and underlying bone morphology used to predict surgical and restorative outcomes.
Full Definition
Introduced in the 2017 AAP/EFP Classification to replace the earlier concept of 'gingival biotype', periodontal phenotype encompasses gingival tissue thickness, the width of keratinised gingiva, and the thickness of the underlying alveolar plate. The phenotype is categorised as thin-scalloped, thick-flat, or thick-scalloped, with each carrying different clinical implications for implant therapy, orthodontic treatment, and restorative work. The shift from 'biotype' to 'phenotype' is a notable editorial pitfall: manuscripts submitted after 2017 using the old terminology should be flagged.
Usage
Usage note: Preferred over 'gingival biotype' since 2017. Flag manuscripts that use 'biotype' post-2017 for terminology update.
In Context
- "Assessment of the periodontal phenotype prior to implant placement is recommended to anticipate soft-tissue management needs." — Clinical guideline
- "The manuscript repeatedly uses 'biotype'; editors should update this to 'phenotype' in line with the 2017 classification." — Editorial revision note
