A Technique to Identify and Reconstruct the Cementoenamel Junction Level Using Combined Periodontal and Restorative Treatment of Gingival Recession. A Prospective Clinical Study

Gingival recession is often associated with abrasion in the cervical area with an unidentifiable cementoenamel junction (CEJ). This condition complicates the diagnosis and treatment of gingival recession. The aim of this study was to propose a technique to identify the CEJ level for planning periodontal and restorative treatment of the recession. The CEJ of a contralateral homologous tooth or adjacent teeth was used to replicate the lost CEJ at the treated tooth. Reconstruction of the CEJ using composite resin and a coronally advanced flap, with or without a connective tissue graft, was performed for 25 recessions in 12 patients. After 2 years, 20 defects (80%) showed complete root coverage with a significant recession reduction (2.4 mm, P .0001).
