Abstract

Background: Artificial tooth wear impacts prosthesis durability and function; understanding material-antagonist interactions guides clinical choices.

Aim: This in-vitro study aimed to assess the wear behavior of isosit and nanohybrid composite resin artificial teeth when opposed to various antagonist materials using 3D volumetric wear analysis.

Materials and methods: Sixty specimens (n = 10 per group) were prepared from two artificial tooth materials and assigned to six antagonist combinations: isosit-isosit, isosit-nanohybrid composite, isosit-porcelain, nanohybrid composite-isosit, nanohybrid composite-nanohybrid composite, and nanohybrid composite-porcelain. Specimens were scanned before and after 600,000 chewing cycles using a structured-light 3D scanner. Volumetric wear was calculated by superimposing pre- and post-test scans. Data were analyzed using two-way ANOVA and Tukey's HSD test (α = 0.05).

Results: Porcelain antagonists produced the highest wear values (p < 0.05). No significant difference was found between isosit and nanohybrid antagonists (p > 0.05). Identical material pairings showed less wear, though differences were not statistically significant.

Conclusions: Porcelain as an antagonist increased wear risk. Using identical materials bilaterally, such as isosit-isosit or nanohybrid-nanohybrid, may help reduce artificial tooth wear in removable prostheses.

利用三维磨损分析体外评估人工牙材料磨损行为。

研究背景：人工牙磨损对修复体耐久性和功能的影响；了解物质拮抗剂相互作用指导临床选择。目的：采用三维体积磨损分析的方法，评估同种异体和纳米杂化复合树脂人工牙相对于各种拮抗剂材料的磨损行为。材料和方法：用两种人工牙材料制备60个标本（每组10个），并分配6种拮抗剂组合：isosit-isosit、isosit-纳米杂化复合材料、isosit-瓷、纳米杂化复合材料-isosit、纳米杂化复合材料-纳米杂化复合材料和纳米杂化复合材料-瓷。使用结构光3D扫描仪扫描600,000个咀嚼循环前后的标本。通过叠加测试前和测试后的扫描来计算体积磨损。数据分析采用双因素方差分析和Tukey’s HSD检验（α = 0.05）。结果：瓷拮抗剂的磨损值最高（p < 0.05）。异糖酸与纳米杂化拮抗剂间无显著差异（p < 0.05）。相同的材料配对显示磨损较少，尽管差异没有统计学意义。结论：瓷作为拮抗剂增加磨损风险。双侧使用相同的材料，如异硅酸-异硅酸或纳米杂化-纳米杂化，可能有助于减少可移动义齿的人工牙磨损。

期刊介绍： Journal of Functional Biomaterials (JFB, ISSN 2079-4983) is an international and interdisciplinary scientific journal that publishes regular research papers (articles), reviews and short communications about applications of materials for biomedical use. JFB covers subjects from chemistry, pharmacy, biology, physics over to engineering. The journal focuses on the preparation, performance and use of functional biomaterials in biomedical devices and their behaviour in physiological environments. Our aim is to encourage scientists to publish their results in as much detail as possible. Therefore, there is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Several topical special issues will be published. Scope: adhesion, adsorption, biocompatibility, biohybrid materials, bio-inert materials, biomaterials, biomedical devices, biomimetic materials, bone repair, cardiovascular devices, ceramics, composite materials, dental implants, dental materials, drug delivery systems, functional biopolymers, glasses, hyper branched polymers, molecularly imprinted polymers (MIPs), nanomedicine, nanoparticles, nanotechnology, natural materials, self-assembly smart materials, stimuli responsive materials, surface modification, tissue devices, tissue engineering, tissue-derived materials, urological devices.
