Brief Summary

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.

Detailed Description

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.

Arm && Interventions

Group	Intervention	Description
Clinical behaviour on teeth prepared without finish line	Retreatment of teeth prepared without finish line	Evaluate the clinical behavior of restorations placed on teeth prepared without finish line, monitoring periodontal status as well as the prostheses to assess stability and treatment predictability.

Primary Outcome Measures

Name	Time	Method
A possible periodontal complications	Through study completion, an average of 15 years.	Analyze periodontal outcome on teeth prepared with biologically oriented preparation technique
biological or mechanical prosthetic complications	Through study completion, an average of 15 years.	Analyze prosthetic outcome on teeth prepared with biologically oriented preparation technique

Secondary Outcome Measures

Name	Time	Method
Patient's level of satisfaction with treatment assessed by means of a visual analogue scale (VAS).	Through study completion, an average of 15 years.	Patient's satisfaction was assesed using a ''Visual Analogue Scale'' (VAS). In wich 0 is the the minimum and 10 de maximum value, and whether higher scores mean a better outcome.
