Abstract: AIM: The aim of this study is to compare and evaluate the marginal fit of CAD-CAM milled PMMA crown fabricated by three different technique Material And Methods:
10 participants were selected who have undergone root canal treatment and mandibular first molar teeth were prepared with a shoulder margin. It was scanned using an intra oral scanner (Dentsply Sirona) of prepared teeth, extraoral scanning of impression and extraoral scanning of casts. The PMMA crown was designed using the scanned STL file with CAD software (Dentsply Sirona).......
