ABSTRACT
Objective To explore the effects of microstructure grinded on the labial face of porcelain fused to metal crown (PFM) in esthetic prosthesis for anterior teeth. Methods 193 patients with single maxillary incisor tooth defects were repaired with 2 crowns for each one. After the crowns being blent colour and molded, the crown A was not grinded particularly on the labial face and the crown B was done according to the records of the microstructure.The patients were allowed to choose the most satisfied one when 2 crowns were cemented temporarily. Results 36 patients chose the crown A and 157 chose B.The difference was significant ( P0.05). Conclusion The crown has great vitality and accordes with the esthetic standards of the patients by way of being grinded microstructure on the labial face.
