Effect of CMR With Different Restorative Materials on Clinical Performance of Indirect Onlay Restorations
Study Details
Study Description
Brief Summary
The current study intends to evaluate the effect of cervical margin relocation with different restorative materials on three-year clinical performance of indirect CAD/CAM onlay restorations. This study is designed to test the null hypothesis that the three-year clinical performance of onlay restorations is significantly affected by cervical margin relocation with different restorative materials.

Outcome Measures
Primary Outcome Measures
- Gingival health [three year follow up]
Gingival Index Scale from 0 to 3 will be used for evaluation considering that score 0 represents normal gigiva while score 3 represents severely inflamed gingiva
- modified FDI (International Dental Federation) clinical Criteria [three year follow up]
Functional Properties of restorations: Fracture of material and retention Marginal adaptation Radiographic examination Biological Properties of restorations Postoperative (hyper-sensitivity and tooth vitality Recurrence of caries Tooth integrity (enamel cracks, tooth fractures) Periodontal Response Adjacent mucosa Descriptive scale from 1 to 5. Note: 1 is clinically excellent 5 is clinically poor. Scores(1-3) are considered sufficient The overall cumulative success rate of restorations will be evaluated
