title: The Octagon Model: a clinical tool for assessing marginal tissue recession.
abstract: The Octagon Model is a clinical assessment tool designed to assess marginal tissue recession (MTR) and estimate the level of difficulty in achieving root coverage. It evaluates eight patient- and siterelated factors: patient's expectations, smoking status, width of keratinized tissue, absence/presence of cervical lesion, interproximal soft tissue/bone level, depth and width of recession defect, and buccal bone thickness. The model is presented in a three-colored diagram to facilitate communication between clinicians and between clinicians and their patients, and to assist clinicians in optimizing treatment plans at both site and patient levels.
