Evaluation of Marginal and Internal Fit of Metal Crowns
Conditions
Brief summary
The goal of this in vitro study is to compare the marginal fit and internal adaptation of all-metal crowns in polished crown preparations and non-polished crown preparations The main question it aims to answer is: are the non polished tooth preparations comparable to polished preparations? We will compare polish and non polish groups and see their effects on marginal fit and internal adaptation of all metal crown

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| marginal fit | six months | The margins of fixed restorations refers to the junction between the prepared tooth structure and the crown restoration |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Internal fit | six months | Internal fit is defined as the perpendicular distance between the framework and abutment teeth and the misfit is measured from occlusal/incisal and axial surfaces to the coping |
