在口腔修复临床工作中制取印模是必不可少的操作程序,在制取的过程中印模会直接接触到患者的唾液、龈沟液、牙菌斑甚至血液,其中含有病原微生物,因此对于口腔印模的消毒应该受到重视。但目前对于各种口腔印模的消毒研究尚未形成一个公认的标准方案,况且口腔印模易受温度、湿度的影响,其精确性又会影响到修复体的精准性。本文对近几年来关于口腔印模的消毒方法与消毒对印模精确性的影响做一综述,希望对口腔临床医生的工作有所帮助,也期望将来出现更精准的、耐消毒的口腔印模材料。
Implants in the clinical work of the oral reparation is essential to the operation of the process, the impression in the process of preparation will be in direct contact with the patient’s saliva, gingival crevicular fluid, plaque and even blood, which contains pathogenic microorganisms, therefore Disinfection of the dental impression should be taken seriously. However, at present, there is not a recognized standard scheme for disinfecting all kinds of dental impressions. Besides, oral impressions are easily affected by temperature and humidity, and their accuracy will affect the accuracy of the prosthesis. This article reviews the impact of sterilization methods and sterilization on impression accuracy in recent years, and hopes to help the oral clinicians. It also expects more accurate and sterilizable oral impressions in the future material.
