Vat Photopolymerization 3D Printing in Dentistry: A Comprehensive Review of Actual Popular Technologies

Abstract

In this comprehensive review, the current state of the art and recent advances in 3D printing in dentistry are explored. This article provides an overview of the fundamental principles of 3D printing with a focus on vat photopolymerization (VP), the most commonly used technological principle in dental practice, which includes SLA, DLP, and LCD (or mSLA) technologies. The advantages, disadvantages, and shortcomings of these technologies are also discussed. This article delves into the key stages of the dental 3D printing process, from computer-aided design (CAD) to postprocessing, emphasizing the importance of postrinsing and postcuring to ensure the biocompatibility of custom-made medical devices. Legal considerations and regulatory obligations related to the production of custom medical devices through 3D printing are also addressed. This article serves as a valuable resource for dental practitioners, researchers, and health care professionals interested in applying this innovative technology in clinical practice.

Effect of Dietary Simulating Solvents on the CAD-CAM Provisional Restorative Materials’ Microhardness and Color Stability Properties: An in vitro Study

“…17,26 While in-use of provisional restorations exposure may be more intermittent, factors like poorly finished restorations or trapped debris at the margins can lead to prolonged contact with these dietary components, potentially amplifying their effects. 16,27 Microhardness is a property used for definite indentation penetration prevention by predicting the material's resistance to wear and abrasion of dental structures opposing them. Strength, Ductility, and proportional limit are properties related to hardness.…”

Mechanical and Material Analysis of 3D-Printed Temporary Materials for Implant Reconstructions—A Pilot Study

“…As a result, the Sonic Mighty 8k offers even faster printing times, which is important for those who require high productivity and short production times. In addition, it maintains a high 8K resolution, guaranteeing precise and aesthetically pleasing prints, which is extremely important for dental prostheses and other medical applications [28].…”

Effects of washing agents on the mechanical and biocompatibility properties of water-washable 3D printing crown and bridge resin

“…The workflow of producing dental restorations with a 3D printer using photopolymerizable resin can be summarized into printing, postwashing, and postcuring 12 . After finishing the printing process, the object must undergo postwashing to remove any residual uncured resin that may adhere to its surface 13 .…”
