A review on Vat Photopolymerization 3D-printing processes for dental application

To give a critical and realistic state-of-the-art overview of research conducted in the field of Vat Photopolymerization for use in the dental field, with recommendations for further research.

The search of articles published for the period 2005-2022 was performed using Scopus and PubMed databases using keywords. Apart from that, a search for patents in the Patentscope database for the period 2000-2021 was also conducted.

Based on the found articles, insight on the publication's activity and discussion of some possible areas of future examination, on the mechanical properties of 3D-printed resin-based dental parts, their biocompatibility, antimicrobial properties, accuracy, and surface properties are presented. After reviewing all relevant articles, it was found that there is a need for more research in order to elevate this field to the next level.

Vat Photopolymerization technologies are evidently more or less incorporated into everyday dental practice. In the future, a complete transition to digital workflow is expected. To enable this, it is necessary to examine in detail the materials used in this field, in order not only to ensure patient safety, but also to reduce the cost of dental services. However, not many studies have been published in the searched databases, and more research is needed, the results of which can be compared with previously conducted studies.
