About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • adult patients (aged over 18 years).
  • non-smokers.
  • periodontally healthy or periodontally managed.
  • patients who had undergone restoration with fixed prostheses (one-piece crowns or fixed partial dentures FPDs) in the aesthetic zone (incisors, canines, premolars, first molars), which needed to be replaced due to biological, esthetic or some other type of problem.

Exclusion criteria

  • patients who were smokers.
  • patients who presented unmanaged parafunctional habits.
  • patients with severe systemic diseases.

Treatment and study plan

Retreatment of teeth prepared without finish line

Procedure

Retreatment of 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).

Primary outcomes

  1. A possible periodontal complications

    Time frame: Through study completion, an average of 15 years.

    Analyze periodontal outcome on teeth prepared with biologically oriented preparation technique

  2. biological or mechanical prosthetic complications

    Time frame: Through study completion, an average of 15 years.

    Analyze prosthetic outcome on teeth prepared with biologically oriented preparation technique

Secondary outcomes

  1. Patient's level of satisfaction with treatment assessed by means of a visual analogue scale (VAS).

    Time frame: 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.
