“…Several recent studies have reported on clinically applied 3D printed complete dentures and demonstrated benefits such as patient satisfaction, higher retention, and fewer sore spots. 12,14,[25][26][27] Moreover, Dentca 3D printed denture teeth have proven mechanical properties, such as chipping strength and indirect tensile fracture resistance, which are comparable to those of conventionally prefabricated denture teeth. 28 However, since there is no long-term experience and no sufficient data has been accumulated yet, more research is needed.…”

Purpose: This study evaluated color stability of Dentca 3D-printed denture teeth, in comparison to color stabilities of four conventional types of denture teeth, upon being immersed in various colorants. Materials and methods: Four types of conventional prefabricated denture teeth (Surpass, GC, Artic 6, Heraeus Kulzer, Premium 6, Heraeus Kulzer, Preference, Candulor), 3D-printed denture teeth (Dentca); and Z250 (Filtek Z250, 3M ESPE) were prepared for testing. The samples were immersed in erythrosine 3%, coffee, cola, and distilled water (DW) at 37°C. Color change (ΔE) was measured by spectrophotometer before immersion and at 7, 14, and 21 days after immersion. One-way analysis of variance was performed along with Tukey's honestly significant difference multiple comparisons test (P<.05). Results: No great difference was observed between the color change of Dentca denture teeth and that of conventional denture teeth in most cases (P>.05). The color change of Dentca denture teeth immersed in erythrosine 3% was greater than that of Surpass (ΔE = 0.67 ± 0.25) after 1 week; Artic 6 (ΔE = 1.44 ± 0.38) and Premium 6 (ΔE = 1.69 ± 0.35) after 2 weeks; and Surpass (ΔE = 1.79 ± 0.49), Artic 6 (ΔE = 2.07 ± 0.21), Premium 6 (ΔE = 2.03 ± 0.75), and Preference (ΔE = 2.01 ± 0.75) after 3 weeks (P<.05). Conclusion: A color change was observed in Dentca denture teeth when immersed in some colorants; however, the maximum value of ΔE for Dentca denture teeth was within the clinically acceptable range.

“…If this technology is well studied and developed, 3D printed denture enables more efficient clinical adaptation which minimizes patient discomfort and potentially reduces long-term residual bone resorption [ 4 ]. Despite the many advantages of CAD/CAM dentures, if they are not well designed, they may show concerns, such as the short borders of denture bases and a lack of close tissue contact, which reduces retention [ 5 , 6 ]. Additionally, the mechanical properties of 3D printed denture teeth manufactured by CAD/CAM are, so far, unknown.…”

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.

Traditionally, a denture base is manufactured using a heat-cured acrylic resin. This type of resin was first used in dental labs in 1936, being a great step forward. Because of the many disadvantages as increased porosity, high water sorption, polymerization shrinkage, allergenic potential and citotoxicity due to the residual monomer, awkward flasking and packaging, and difficult processing, alternatives were continuously searched. Monomer-free and high-impact acrylics were developed, and gold plating of the denture base was experienced, in order to provide an alternative to allergic patients. Once polymers developed, new types of resins, such as polyamides (nylon), acetal, epoxy resins, styrene, polycarbonate, vinyl, urethane, polyether ether ketone (PEEK), became available on the dental market, accompanied by modern technologies, such as injection. CAD/CAM milled and 3D printed denture bases represent the present state of the art in this domain. Our chapter aims to present these alternative materials, which are safe to use in cases of allergic patients and guarantee a healthy oral environment and a high degree of comfort.
