摘要： 目的: 探究3种不同消毒方式对蜡牙合堤形变程度的影响。方法: 采用硅橡胶模具制备36个标准规格为10 mm×10 mm×28 mm长方体蜡堤试件,固定于20 mm×20 mm×20 mm超硬石膏底座。使用3Shape-D2000扫描仪获取蜡堤扫描数据作为对照组(0组)。试件随机分为臭氧消毒组(A)、紫外线消毒组(B)及酸性氧化电位水消毒组(C),每组随机分为2个亚组分别接受30 min和60 min消毒(30组和60组,n=6)。对消毒后的试件再次扫描。使用通过Geomagic Studio软件将对照组与实验组数据拟合后进行三维偏差分析,采用多因素方差分析进行比较。结果: 与对照组相比,A30、A60组平均尺寸偏差为(21±6) μm、(43±21) μm;B30、B60组为(30±10) μm、(374±16) μm;C30、C60组为(36±20) μm、(56±35) μm。B60组的形变量显著高于其他组(P<0.001),超出临床可接受阈值(300 μm)。A30和A60组之间、B30和B60组之间存在显著差异(P<0.001),C30和C60组之间比较无统计学差异。结论: 在消毒效能与尺寸稳定性方面,酸性氧化电位水消毒更具综合优势,建议优先采用。

Abstract: Objective: To explore the effects of three different disinfection methods on the deformation extent of wax occlusal rims. Methods: Thirty-six rectangular wax occlusal rim specimens with standard dimensions of 10 mm×10 mm×28 mm were prepared using silicone rubber molds and fixed onto 20 mm×20 mm×20 mm ultra-hard gypsum bases. The specimens were scanned using a 3Shape D2000 scanner to obtain baseline data for the control group (Group 0). The specimens were then randomly divided into three experimental groups: ozone disinfection (Group A), ultraviolet disinfection (Group B), and acidic electrolyzed water disinfection (Group C). Each group was further divided into two subgroups receiving 30-minute (30 Group) and 60-minute (60 Group) disinfection treatments (n=6 per subgroup). Post-disinfection scans were performed on all specimens. Three-dimensional deviation analysis was conducted by fitting the experimental group data to the control group data using Geomagic Studio software. Results: Compared with the control group, the average dimensional deviations of groups A30 and A60 were (21±6) μm and (43±21) μm, respectively; those of groups B30 and B60 were (30±10) μm and (374±16) μm; and those of groups C30 and C60 were (36±20) μm and (56±35) μm. The deformation of group B60 was significantly higher than that of other groups (P<0.001), exceeding the clinically acceptable threshold (300 μm). There were significant differences between groups A30 and A60, and between groups B30 and B60 (P<0.001), while there was no significant difference between groups C30 and C60. Conclusion: In terms of disinfection efficiency and dimensional stability, acidic electrolyzed water disinfection has more comprehensive advantages and is recommended as the preferred method.
