When patients receive 3D-printed dental prostheses, the success of that piece depends on more than just the material. It also depends on how the object is positioned during the printing process. This study looked at how different angles—like vertical or slanted positions—impact the physical properties of these dental pieces.
Researchers found that the orientation significantly affects mechanical strength, especially in vertical or oblique (tilted) positions. While factors like density and hardness were less affected by the angle, accuracy and precision improved when using specific angles like 0, 30, or 45 degrees. These findings suggest that choosing an oblique orientation can offer a good balance between making a piece strong enough to last and accurate enough to fit well.
It is important to note that this research was conducted in a lab setting rather than in patients' mouths. While certain angles improve strength and precision, the study did not find one single perfect angle for every type of dental fit. Because results can vary based on specific conditions, your dentist will still need to determine the best approach for your unique case.
