Conditions
Summary
The objectives of the present prospective randomized clinical study are to evaluate and to compare the survival and success rates, possible biological and technical complications, and the clinical performance of metal-ceramic, monolithic zirconia and resin-matrix posterior crowns. The null hypothesis is that no differences would be found between the parameters studied for each type of restoration.
Eligibility
Inclusion Criteria6
- One posterior tooth (molar or premolar) to be crowned,
- Vital abutments or abutments with sufficient endodontic treatment
- Abutment not crowned previously
- Periodontally healthy abutments with no signs of bone resorption or periapical disease --
- Adequate occlusogingival height
- Stable occlusion, and the presence of natural dentition in the antagonist arch.
Exclusion Criteria2
- Patients who present reduced crown length (less than 3 mm occlusogingival height
- Poor oral hygiene, high caries activity, active periodontal disease or bruxism.
