摘　　要：目的对热压膜材料和自凝塑料这两种不同材质的磁力矫治器表面细菌粘附及矫治器的卫生情况进行临床对比研究，为临床使用热压膜材料提供依据。方法早期反袷畸形患者18例随机分为两组，每组9例。A组戴用自凝塑料制作的磁力矫治器，B组戴用热压膜材料为主制作的磁力矫治器。对矫治器表面细菌附着情况，矫治器异味、色素沉着、软垢的效果进行研究。结果A、B两组菌落计数在矫治前比较差异无统计学意义（P〉0．05）。在矫治后6个月及1年后A组菌落计数、异味、色素沉着情况明显大于B组，差异有统计学意义（P〈0．05）。A、B两组菌落计数、异味、色素沉着情况随着矫治时间的增加而增加，差异有统计学意义（P〈0．05）。结论热压膜材料的卫生情况明显好于聚甲基丙烯酸甲酯，建议临床使用热压膜材料代替。但要达到良好的卫生效果，采取正确的口腔清洁措施，良好的饮食习惯，按医嘱维护和清洗矫治器都是十分必要的。Objective To investigate the bacterial adhesion and oral hygiene of magnetic appli- ance with the thermoplastic materials and polymethyl methacrylate plastics, in order to provide reference for clinics. Methods Eighteen patients with crossbite were selected and divided into polymethyl methac- rylate plastics group（ group A）and thermoplastic materials （group B ）, with 9 cases in each group. The two groups were observed with the indexes as follows： colony counting, peculiar smell, pigmentation, soft scale. Results Before treatment, there was no significant difference in colony counting between the two groups（P 〉0. 05）. After treatment for 6 months and 1 years, there were significant differences in colony counting, peculiar smell and pigmentation between the two groups （ P 〈 0. 05 ）, and increased with time. Conclusions The thermoplastic materials are superior to polymethyl methacrylate plastics in oral hy- giene. But to achieve good hygiene effect, it is important to have oral health, healthy eating behaviors, maintenance and cleaning appliance.
