Effect of axial height and palatal wall on the resistance form of a maxillary anterior metal-ceramic crown preparation.
The effect of palatal wall modifications and height of a maxillary central incisor on the resistance form of metal-ceramic crowns are compared. Dies with adequate preparation height show no crown dislodgement in groups with a palatal wall, palatal wall/groove, and no palatal wall. This study suggests the use of a palatal groove improves the resistance to dislodgement in short maxillary anterior tooth preparations.
