Abstract
Purpose: The purpose this study was to evaluate the marginal fitness of metal copings fabricated using rapid
prototyping method and to compare the fitness with copings by conventional method. Then clinical availability of fixed dental prostheses (FDPs) fabricated using rapid prototyping method shall be confirmed based on marginal fitness.
Methods: Ten same cases of3 unit FDPs epoxy models (abutment teeth 14 and 16) were manufactured. Each of
ten epoxy models were scanned by 3shape D-700 scanner to be designed by experienced technician, and photopolymer 3 unit FDPs were fabricated using rapid prototyping methodand fabricated using Lost wax technique (LW) with same models. Marginal fitness of 3 unit FDPs were measured by silicone replica technique. T-test of independent sample for statistical analysis was executed with SPSS 12.0K for Windows.
Results: Significantly higher mean (SD) marginal fitness (P<.000) were observed in the RP group (95.9 (18.0)
compared to the conventionally LW group (80.1 (13.8).
Conclusion: Marginal fitness of LW group showed excellent rather than RP group. However marginal fitness of 3
unit FDPs fabricated by RP method did not get out of clinical allowance value range significantly to allow clinical application.
