Overview

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
