ABSTRACT
Objective:
The aim of this study was to evaluate the cervical fit of full metal crowns using four different elastomers.Methods:
A stainless steel metallic die similar to a prepared first upper molar was obtained. Four di-fferent elastomeric impression materials were utilized polysulfide (A), polyether (B), condensation silicone (C) and addition silicone (D). Forty molds were created, 10 for each group. It was obtained 40 gypsum abutments. After the end of this stage, it was performed complete metal crowns on all specimens. Crown displacement was measured through a comparative microscope, obtaining diametrically opposite points.Results:
The re-sults were the following Group D (31.97 um), Group B (49.57 um), Group A (51.12 um), Group C (61.12 um). The analysis of variance (ANOVA) test and a Tukey test for multiple comparisons were used to analyze the results.Conclusions:
There were significant differences among all groups, except for Groups A and B. The major result of displacement was Group C. The best results were shown by Group D (p < 0.05).
