Accuracy of full arch models achieved from different 3D printers

This work titled "Accuracy of full arch models achieved from different 3D printers" addresses significant advancements in the field of dentistry thanks to CAD-CAM technology and 3D printing, which have transformed precision and efficiency in dental treatments. The development of stereolithography and other 3D printing methods has revolutionized the creation of dental models, prosthetics, and surgical devices. The study focused on comparing the accuracy of three 3D printers based on a scanned initial model of a dental arch. Using the STL format for digital designs, complete arches were printed with specific resins on each printer. Subsequently, the printed models were evaluated through scanning and digital overlay comparison using Exocad software. The results showed variations in accuracy among the printers, highlighting that the VeriBUILD 79200 was the most precise, followed by the 3D Sonic Mighty 4K and the UV MAX. It was concluded that although 3D printers offer significant advantages in terms of detail reproduction, it is crucial to consider limitations and variability among models and technologies when selecting one for precise clinical applications in dentistry. This study underscores the importance of ongoing research and future standardization of criteria to evaluate the accuracy of 3D printed models in dentistry, aiming to optimize clinical and educational outcomes in the field.
