Summary

This study aims to evaluate the periodontal response of teeth prepared with a biologically oriented preparation technique (BOPT) compared to conventional preparation for all-ceramic crowns.

Detailed description

The study aims to evaluate the clinical performance of all-ceramic crowns on teeth prepared with two different types of preparations. This randomized controlled trial will include 60 teeth divided into two groups: 30 teeth will be prepared with BOPT, and 30 teeth will be prepared with shoulder margins. All teeth will receive monolithic or bi-layered ceramic crowns. Patients are planned to attend follow-up visits after 3, 6, 12, and 18 months, respectively, after cementation. Probing depth, gingival recession, bleeding on probing, gingival index, gingival thickness, patient opinion, and mechanical and biological complications are all recorded at check-up appointments.

Conditions

• Crowns
• Tooth Preparation
