Clinical Trial Summary

The current study intends to evaluate the effect of cervical margin relocation with different restorative materials on three-year clinical performance of indirect Computer-Aided-Design (CAD)/ Computer-Aided-Manufacture (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

Type	Measure	Description	Time frame	Safety issue
Primary	Gingiva	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	three year follow up
Primary	Modified World Dental Federation (FDI) clinical Criteria	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	three year follow up
