- 主要终点
- Restorations will be evaluated at recall intervals of 3 months, 6 months and 9 months using Modified Ryge’s criteria for anatomical form, restoration staining, marginal discoloration, color match, surface roughness, marginal adaptation and periodontal status. Comparison of proportion of success between groups will be done by chi-square test; p value less than 0.05 will be considered as statistically significant.

简要总结
· Objectives:
- To clinically evaluatethe performance of two 3D printed resin crowns as long-term definitiverestorations
· 2. Toclinically evaluate the performance of 3D printed resin crowns as compared topressed lithium disilicate crowns as long-term definitive restorations withrespect to anatomic form, restoration staining, marginal discoloration, colormatch, surface roughness, marginal adaptation, and periodontal status of theteeth
· *Hypothesis:*There will be no differences between the 3D printed resin crowns and pressedlithium disilicate crowns in terms of longevity of the restorations.
