Evaluation of marginal fitness of two 3D printed materials using micro-computed tomography approach (µ-CT).

Abstract

Abstract: to assess the marginal fitness of two commercially available 3D printed resins with the aid of micro CT-scan

Material and methods: acrylic tooth was prepared using dental surveyor then its scanned with an intra-oral scanner to convert it to metal, 2 groups of the crown was made by DLP Asiga 3D printer, 6 for each group for Saremco and Senertek respectively. Marginal fit was evaluated at 8 points (2 points for each surface)

Result: µ-ct shows acceptable marginal fitness (126.27µm  (12.71 SD), 79.41µm (6.61 SD)) for senertek and saremco respectively.

Conclusion: According to the study outcomes marginal fitness data obtained of both materials show good marginal adaptation to be used as permanent crown with some preference toward saremco over senertek company.
