Özet

Objective: The objective of this study is to investigate the flexural strength and modulus of elasticity values of temporary fixed prosthetic materials produced with different orientation angles (0°, 45°, 90°). Methods: In this study, bar-shaped specimens (25 mm × 2 mm × 2 mm) with 0°-45°-90° orientation angles were prepared by 3D printing using a temporary restoration resin (Ackuretta Qura Crown Temporary Crown Photopolymer Resin), totaling thirty-nine specimens (n=13). The specimens underwent a twenty-four-hour storage period in distilled water at 37°C, after which their flexural strength and their modulus of elasticity values were measured and subsequently compared. Results: The flexural strength and modulus of the elasticity values of the temporary fixed prostheses produced with different orientation angles (0°, 45°, 90°) exhibited no statistically significant difference (P>.05). Conclusion: The different production angles did not affect the flexural and modulus of the elasticity values of the test specimens produced by the 3D printing. According to the ISO 10477 standards, the flexural strength values meet the criteria (fifty MPa value).
