Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults over 18 with stable occlusion and good oral hygiene who require at least two full crowns.

Probably not a fit

Patients with active periodontal disease, poor oral hygiene, or systemic conditions affecting periodontal health may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial evaluates the periodontal response of teeth prepared using a biologically oriented preparation technique (BOPT) compared to conventional preparation methods for all-ceramic crowns. A total of 60 teeth will be randomly assigned to either BOPT or shoulder margin preparation, with all receiving ceramic crowns. Patients will undergo follow-up visits at 3, 6, 12, and 18 months post-cementation to assess various clinical outcomes, including probing depth and gingival health. The study aims to determine which preparation method yields better clinical performance and patient satisfaction.

Why it matters

Potential benefit: If successful, this study could lead to improved periodontal health outcomes for patients receiving all-ceramic crowns.

How similar studies have gone: While similar studies have explored various preparation techniques, the specific biologically oriented preparation technique in this context is relatively novel.
