Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 1.Change from baseline to 12 months regarding Anatomic form | alpha: The general contour of the restorations follows the contour bravo: the general contour of the restoration does not follow the contour of the tooth charlie: The restoration has an overhang does | baseline, 3-month, 6-month,12-month | 
| 2.Change from baseline to 12 months regarding Marginal adaptation | alpha: Explorer does not catch or has one-way catch when drawn across the restoration/tooth interface bravo: explorer falls into crevice drawn across the restoration/tooth interface charlie: Dentin or base is exposed along the margin | baseline, 3-month, 6-month,12-month | 
| 3.Change from baseline to 12 months regarding Surface roughness | alpha: the surface of the restoration does not have any surface defects bravo: the surface of the restoration has minimal surface defects charlie: the surface of the restoration has severe surface defects | baseline, 3-month, 6-month,12-month | 
| 4.Change from baseline to 12 months regarding Marginal staining | alpha: there is no discoloration between the restorations and tooth bravo: there is discoloration on less than half of the circumferential margin charlie: there is discoloration on more than half of the circumferential margin | baseline, 3-month, 6-month,12-month | 
| 5.Change from baseline to 12 months regarding Retention | alpha: intact bravo: chipped/loss of material charlie: complete loss of crown | baseline, 3-month, 6-month,12-month | 
| 6.Change from baseline to 12 months regarding Incisal wear | alpha: intact bravo: wear of occlusal surface without tooth surface exposure charlie: wear of occlusal surface with tooth surface exposure | baseline, 3-month, 6-month,12-month |
