Abstract

Background and Aims: One of the most important challenges for dentists is providing a crown with appropriate marginal fit and gap. The 135-degree Tooth preparation found to have some advantages such as technical ease and appropriate finish line record. Despite the advantages of 135-degree Tooth preparation, scant research has been done in this area. Therefore, the aim of this study was to compare 135-degree and deep chamfer Tooth preparation on the marginal fit and marginal gap of posterior metal-ceramic crowns. Materials and Methods: Deep chamfer and 135-degree Tooth preparation were performed on the two first mandibular molars with healthy coronal tissue and similar size. Impression was taken from each tooth and 30 crowns were made on each die. The sample plastered with fit checkers were pressed under the force of 40 N for 3 min in a universal testing machine. They were measured and recorded under a loop with 40x power in three points on each aspect. Data were analyzed by Wilcoxon and Kolmogorov-Smirnov tests using SPSS version 24. Results: The mean marginal fit values in deep chamfer and 135-degree were 48. 5417μ m and 55. 3333 μ m, respectively with no statistically significant difference (P>0. 05). While the mean marginal gap in deep chamfer (2. 4833 μ m) was significantly higher (P<0. 05) than 135-degree (1. 0083). Conclusion: It can be concluded that the marginal gap by 135-degree’ s Tooth preparation was lower than that of deep chamfer in metal-ceramic crowns. However, no significant difference in the marginal fit between the deep chamfer and 135-degree Tooth preparation was found.
