The practice of dentistry was an early adopter of photopolymerization and notably took on the challenge of reliably photocuring thick, highly light attenuating dental composite restoratives under non-ideal conditions, i.e. in the patient’s mouth. Other photopolymers including polymer-modified hybrid materials spanning a range of dental applications are also now in common place use. More recently, the profession has also embraced the concept of digital dentistry in terms of accurate, high-resolution detailing of the dental morphology of individual patients in electronic data files that can then be used in to produce a wide variety of patient-specific items whether through the subtractive process of milling pre-formed blocks of ceramic and polymer-based materials or via the additive manufacturing approach that encompasses several 3D printing techniques. This presentation will highlight the use of photopolymerization-based 3D printing with SLA/DLP and ink jet processes. The intent is to show what is already in widespread use as well as focusing on the challenges and opportunities associated with new photo-printed polymer application areas poised to significantly reshape the dental profession through ongoing progress in printing platforms, software design and materials development that are being pursued very actively.
