“…Arguably, one of the procedures that can benefit the most from the recent developments in 3D printing technologies is the fabrication of provisional crowns and bridges. Different from 3D printing of complex, large scale, full-arch structures, like orthodontic appliances 20 , surgical guides 16–18 , and dentals casts 14 , 3D printing of single unit crowns may be done in as little 10–20 min. Therefore, it is not hard to imagine a clinical situation where the clinician could prepare a tooth, scan it, send it to a chair-side 3D printer, and proceed with other procedures in the same patient while the crown is being printed.…”

“…However, despite the relatively large number of recent review papers discussing the use 3D printing in dentistry 1,3,5,6,14 , examples in the literature actually addressing questions pertaining to parameters defining the characteristics and properties of 3D printed restorative dental materials is strikingly low 12,15 . Fabrication of surgical guides 16–18 , diagnostic models 19 , occlusal splints 20 , and a myriad of other applications that are not targeted at printing of direct or indirect intraoral restorative materials are already a clinical reality. These examples, however, have generally used polymers that have little potential for intraoral clinical application due to lack of regulatory approval, and incompatibility of their properties with medium to long-term dental applications.…”

“…Denture teeth are mainly composed of polymethylmethacrylate (PMMA) or urethane dimethacrylate (UDMA) resins. The minor components of each type of denture tooth and the size and amount of the filler vary [ 45 ]. There have been few other studies on the biomechanical aspects of 3D printed resin teeth.…”

3D Printing of Resin Material for Denture Artificial Teeth: Chipping and Indirect Tensile Fracture Resistance

et al. 2018

3D printing of denture artificial teeth with resin materials is worthy of study in a novel way. This study evaluated chipping and indirect tensile fracture resistance of 3D printing resin material (Dentca 3D printing denture teeth resin) compared with conventionally prefabricated resin denture teeth (Premium-8, Surpass, SR-Orthosit-PE, and Preference). One hundred tooth specimens were prepared for testing. The 3D printed tooth specimens were printed at a 50 µm layer thickness with methacrylate-based photopolymerized resin by stereolithography 3D printing. Chipping and indirect tensile fracture tests were conducted at a speed of 1 mm/min until fracture. The indirect tensile fracture loads of the 3D printed resin teeth were higher than those of Premium-8, Surpass, and SR-Orthosit-PE, and lower than those of Preference teeth. Regarding chipping resistance, the 3D printed resin teeth were not different from Surpass and SR-Orthosit-PE, and were lower than Premium-8 and Preference teeth. The 3D printed resin teeth exhibited vertical fracture of the loaded cusp without deformation in chipping. The 3D printed resin teeth showed simultaneous fracture of two cusps in indirect tensile fracture, unlike other teeth. The results of this study suggest that 3D printing technology using resin materials provides adequate fracture resistance for denture artificial tooth use.

Purpose The purpose of this paper is to establish a chair-side design and production method for a tooth-supported fixed implant guide and to evaluate its accuracy. Design/methodology/approach Three-dimensional (3D) data of the alveolar ridge, adjacent teeth and antagonistic teeth were acquired from models of the edentulous area of 30 patients. The implant guides were then constructed using self-developed computer-aided design software and chair-side fused deposition modelling 3D-printing and positioned on a dental model. A model scanner was used to acquire 3D data of the positioned implant guides, and the overall error was then evaluated. Findings The overall error was 0.599 ± 0.146 mm (n = 30). One-way ANOVA revealed no statistical differences among the 30 implant guides. The gap between the occlusal surface of the teeth covering and the tissue surface of the implant guide was measured. The maximum gap after positioning of the implant guide was 0.341 mm (mean, 0.179 ± 0.019 mm). The implanted axes of the printed implant guide and designed guide were compared in terms of overall, lateral and angular error, which were 0.104 ± 0.004 mm, 0.097 ± 0.003 mm, and 2.053° ± 0.017°, respectively. Originality/value The results of this study demonstrated that the accuracy of a new chair-side tooth-supported fixed implant guide can satisfy clinical requirements.
