Abstract

Purpose: This study aimed to compare the marginal adaptation of different framework materials polyetheretherketone (PEEK), zirconia, and cobalt-chromium (Co-Cr) through direct metal laser sintered (DMLS) and conventional casting (CC) in fixed prosthetic restorations. Materials and Methods: A total of 80 stainless steel dies were embedded in silicone molds, and the master models obtained were divided into four groups (n=20): PEEK, zirconia, Co-Cr through DMLS and CC frameworks. The vertical marginal gap was measured by stereomicroscope at ×20 magnification. In addition to descriptive statistics in the evaluation of data, one-way ANOVA was used with the post hoc multiple comparison test Tamhane’s T2, as the data were normally distributed and variances differed according to the Kolmogorov–Smirnov and Shapiro–Wilk tests. Results: There was a statistically significant difference in vertical marginal gap before and after cementation in all groups (p<0.05). Conclusion: Before and after cementation, vertical marginal gap values of laser sintered Co-Cr, zirconia, and PEEK frameworks were clinically acceptable. Keywords: PEEK; Marginal Adaptation; Laser Sintered Co-Cr; Zirconia; Framework
