Abstract

Purpose: To evaluate the effect of mechanical, chemical, and mechanical-chemical surface treatment methods on shear bond strength between acrylic denture teeth and thermoplastic nylon denture base.

Materials and methods: Maxillary central incisor teeth were treated with five different surface treatment methods: mechanical (sandblasting, T-shape diatoric holes), chemical (5% acetic acid solution, bonding agent), and mechanical-chemical (sandblasting + bonding agent) were embedded in thermoplastic nylon denture base (n = 10). A universal testing machine with a crosshead speed of 0.5 mm per minute was used to test the shear bond strength. Data obtained were statistically evaluated using one-way ANOVA and followed with Tukey post hoc test (α = 0.05) RESULTS: T-shaped diatoric holes exhibited significantly higher shear bond strength among the surface treatment groups, followed by sandblasting + bonding agent, sandblasting, bonding agent, and the acetic acid group (p < 0.001) CONCLUSION: T-shaped diatoric holes as a mechanical surface treatment showed higher shear bond strength than other methods.

各种表面处理方法对丙烯酸义齿与热塑性尼龙义齿基托之间剪切粘接强度的影响。

目的：评估机械、化学和机械化学表面处理方法对丙烯酸义齿与热塑性尼龙义齿基托之间剪切粘接强度的影响：采用五种不同的表面处理方法对上颌中切牙进行处理：机械法（喷砂、T 型透气孔）、化学法（5% 乙酸溶液、粘接剂）和机械化学法（喷砂 + 粘接剂），并将其嵌入热塑性尼龙义齿基托（n = 10）。使用十字头速度为每分钟 0.5 毫米的万能试验机测试剪切粘接强度。采用单因素方差分析对所得数据进行统计评估，并进行 Tukey 后检验（α = 0.05），结果显示：在各表面处理组中，T 型透气孔的剪切粘接强度明显更高，其次是喷砂+粘接剂组、喷砂组、粘接剂组和醋酸组（P < 0.001），结论是：T 型透气孔作为一种机械表面处理方法，其剪切粘接强度高于其他方法。

期刊介绍： The Journal of Prosthodontics promotes the advanced study and practice of prosthodontics, implant, esthetic, and reconstructive dentistry. It is the official journal of the American College of Prosthodontists, the American Dental Association-recognized voice of the Specialty of Prosthodontics. The journal publishes evidence-based original scientific articles presenting information that is relevant and useful to prosthodontists. Additionally, it publishes reports of innovative techniques, new instructional methodologies, and instructive clinical reports with an interdisciplinary flair. The journal is particularly focused on promoting the study and use of cutting-edge technology and positioning prosthodontists as the early-adopters of new technology in the dental community.
