Abstract

Purpose: The purpose of this study were to evaluate the quality of dental prostheses printed by 3-dimensional printing system.

Methods: Mater model was prepared and ten study models were fabricated. Ten single crowns were printed by 3D-printing system(Resin group) and another ten single crowns using casting method were manufactured(Metal group). The marginal adaptation of single crowns were measured using by silicone replica technique. Silicone replicas were sectioned four times. The marginal adaptations were evaluated using by digital microscope. Statistical analyses were performed with Mann-Whitney test(α=0.05).

Results: Mean ± standard deviations of all marginal adaptations were 92.1(20.0)㎛ for Metal group and 69.7(12.3)㎛ for Resin group. Two groups were no statistically significant differences(p>0.05).

Conclusion: Marginal adaptation of single crowns printed by 3D-printing system were ranged within the clinical recommendation.

3D 프린팅 기술로 제작된 보철물이 주조를 통해 제작된 보철물의 변연 적합도 보다 우수하지 못하였으나 통계적으로 유의하지 않았다.
