颌面硅橡胶赝复体是重建患者容貌、恢复患者自信心最重要的修复治疗方法。颜色仿真是颌面赝复体修复成功的关键因素之一,变色和褪色则是赝复体更换的主要原因。影响颌面硅橡胶赝复体颜色的因素主要有3个方面:首先是着色剂的性质,包括色彩稳定性、固化稳定性以及是否添加了遮色剂;其次为硅橡胶赝复体的配色方法,可分为人工配色和计算机配色2个方面;最后为赝复体使用过程中的环境因素,包括紫外线、微波消毒因素、热因素、臭氧以及外源性染色因素。本文就影响赝复体颜色3个方面的因素作一综述。
Maxillofacial silicone rubber prosthesis is to restore the patient’s appearance, restore the patient’s confidence in the most important repair treatment. Color simulation is one of the key factors in the successful restoration of maxillofacial prostheses, and discoloration and fading are the main reasons for the replacement of prostheses. There are mainly three factors affecting the color of maxillofacial silicone prostheses: first, the properties of the colorant, including color stability, curing stability and whether or not to add opacifying agents; followed by the color matching method of silicone rubber prostheses , Which can be divided into two aspects: artificial color matching and computer color matching. Finally, the environmental factors in the process of prosthesis use include UV, microwave disinfection, heat, ozone and exogenous staining. This article reviews the factors that affect the color of prostheses in three aspects.
