Periodontal Outcomes and Digital Volumetric Variation Following BOPT Restorations

Completed

• Conditions: Gingival Recession
• Interventions: Procedure: Biologically Oriented Preparation Technique

• Registration Number: NCT06485999
• Lead Sponsor: University of Valencia

Brief Summary

Technology is becoming increasingly essential in dentistry, and many procedures now require the use of an intraoral scanner. The goal of scanning the oral cavity is to create digital impressions, which are crucial for the fabrication of any dental prosthesis, as three-dimensional models of the dentition are needed.

Alongside technological advancements, new techniques for preparation in fixed dental prosthetics are being developed. An example is the BOPT technique, which involves vertical tooth preparation without a finishing line, associated with gingival sulcus curettage. The technique aims to improve the health and stability of gingival tissues over time.

Since it is a technique still not widely used, there is a need to intensify studies on the subject, justifying the conduct of this observational research aimed at assessing, through scanning and image overlay programs, the volumetric change of gingival tissues after the installation of ceramic prostheses with BOPT-type carving

Detailed Description

The aim of this study was to analyze the behavior of the periodontal tissues around teeth in the anterior region when restored with zirconia single crowns, using a biologically oriented preparation technique (BOPT). The study will investigate tooth-supported single crowns in the anterior region that were fabricated with a full zirconia core, in 18 patients, in the past 3 years. Follow-up analysis will measure periodontal responses by evaluating the following variables: plaque index (PI); probing depth (PD); gingival index (GI); and gingival thickness adjacent to the restoration using intraoral scanning.

The images of the scanning before and after BOPT restoration will be overlap by using a software tool named Geomagic. This program can quantify the changes of gingival thickness in different points defined by the investigator.
