Buccal bone thickness at dental implants in the aesthetic zone: a 1-year follow-up cone beam computed tomography study

Sufficient buccal bone thickness (BBT) is important for an optimal aesthetic outcome of implant treatment in the aesthetic zone. The aim of the study was to assess BBT at dental implants placed in the aesthetic zone (incisor, canine or first premolar in the maxilla) (immediate or delayed, with or without immediate provisionalization) with cone beam computer tomography (CBCT) as a function of time.Eighty patients were divided into 4 groups according to size of the buccal bony defect (<5 or ≥5 mm) after removal of the tooth, and timing of implant placement and provisionalization.
