The purpose is to evaluate the clinical and biological behavior of full coverage restorations on teeth prepared without finish line.~This prospective study included 149 teeth treated using biologically oriented preparation technique (BOPT). The sample (149 teeth) was divided into two groups: Seventy four teeth restored with crowns, and 75 teeth supporting fixed partial dentures (FPD). Restorations were fabricated with zirconium oxide cores and ceramic coverings. Patients attended regular annual check-ups when probe depth, presence of inflammation with bleeding on probing, presence of plaque, gingival thickness, marginal stability, biological or mechanical complications, and the patient's level of satisfaction were registered.
The aim of this study is to evaluate the clinical and biological behavior of full coverage restorations on teeth prepared without finish line in a prospective clinical study.
