In restorative treatment using fixed dental prostheses, dentists should select appropriate restoration material among various types of dental materials. The strength, marginal fit, esthetics, wear resistance, biocompatibility, and cost are important factors in the choice of restoration materials. The present case showed a surface stain on a monolithic zirconia restoration that was due to wear between the monolithic zirconia restoration and the base metal alloy restoration. This phenomenon was confirmed by surface roughness measurement and electron probe micro-analysis.
在使用固定义齿的修复治疗中，牙医应在各种牙科材料中选择合适的修复材料。强度、边缘适合性、美观性、耐磨性、生物相容性和成本是选择修复材料时的重要因素。本病例显示，整体式氧化锆修复体上出现表面污渍，这是由于整体式氧化锆修复体与贱金属合金修复体之间的磨损所致。通过表面粗糙度测量和电子探针微分析证实了这一现象。
