摘要
背景:目前,硅橡胶作为颌面部缺损常用的修复材料在临床修复中得到广泛应用,然而,赝复体硅橡胶的色彩不稳定性是造成其使用寿命缩短的主要因素。目的:对影响赝复体硅橡胶色彩稳定性的因素进行总结,为临床应用提供参考依据。方法:分别以"硅橡胶;赝复体","siliastic;prosthesis"为检索词,应用计算机检索重庆维普(VIP)期刊全文数据库及Pubmed数据库1987-09/2009-12有关文章。纳入有关硅橡胶变色的文献。排除与研究目的无关和内容重复者。保留38篇文献做进一步分析。结果与结论:总结了赝复体硅橡胶变色的多种影响因素,其中,光学性质、着色、以及材料的老化与赝复体硅橡胶色彩的稳定性密切相关。针对上述因素,研究利用其相关预防措施延缓赝复体的变色,增加赝复体的使用寿命是当前面临的重要课题。对于从分子水平探索赝复体色彩不稳定性的机制,尚需进一步研究。
BACKGROUND：Currently,silicone elastomer has been widely used as an ideal material of repairing maxillofacial defects.However,instable color of elastomer prosthesis is the key factor of influencing the serve life.OBJECTIVE：To summarize the influencing factors on the color stability of silicone elastomer prosthesis,and to provide evidence for clinical instruction.METHODS：Using＂silicone elastomer,prosthesis＂in Chinese and in English,a computer search was performed among VIP Periodical Full-text Database and PubMed database from September 1987 to December 2009 to retrieve articles on chromatology instability.Literatures about silicone tube colors were included.Literatures of irrelevant purpose and repetitive content were excluded.Thirty-eight literatures were involved in analysis.RESULTS AND CONCLUSION：The influencing factors of the color stability of maxillofacial elastomer were summarized.The optical qualities,coloration,and the aging of materials are closely relative to the color stability of silicone elastomer prosthesis.Therefore,how to prevent the elastomer from fading and to prolong the serve life of the prosthesis is a prospective topic of current studies.However,the mechanism of the color instability of the prosthesis needs to be further explored on the molecule level.
