About

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.

Full 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.

Enrollment: 60 estimated patients

Sex: All

Ages: 19 to 80 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Patients older than 18.
• Two teeth at least needed to be restored with full crowns (each patient needs at least two single crowns).
• Stable occlusion.
• Good oral hygiene.
• Periodontally healthy teeth.
• Nonsmoking or smoking less than ten cigarettes/day.
• Probing depth between 1 and 3 mm.

Exclusion criteria

• Patients younger than 18.
• Parafunctional habits.
• Active periodontal disease.
• Poor oral hygiene.
• Systemic disease that may affect the periodontal health.
• Pregnancy.
• Radiation or chemotherapy.
• Treatment by Bisphosphonates medication.
• Patients who are unable or unwilling to attend follow-up visits
