摘要

研究目的本研究旨在评估注射成型热塑性聚酰胺 Vertex ThermoSens 义齿基托树脂在 Polident 3 分钟义齿清洁剂中浸泡 3 分钟后的颜色稳定性、表面粗糙度和弯曲性能:处理了 60 个试样(Vertex ThermoSens),并根据测试类型分为两大组(n = 30)。第一组又分为两个亚组(n = 15):浸泡在蒸馏水中的对照组(G1DW)和浸泡在 Polident 洁牙液中的测试组(G1PD)。第 2 组分为三个子组:未浸泡组(G2None)、浸泡在蒸馏水中的试验组(G2DW)和浸泡在 Polident 清洁剂溶液中的试验组(G2PD)。利用 CIE Lab* 公式计算 ∆E。光学三维表面分析仪和三点弯曲测试分别用于评估表面粗糙度和 E。数据采用配对样本 t 检验进行统计分析,以确定浸泡前后各组内的差异。此外,还采用独立样本 t 检验和单因素方差分析来分析组间差异。显著性水平为 P <0.05:结果表明,在蒸馏水中浸泡后,所有颜色成分(L*、a*、b*)的∆E 都有轻微的统计学差异(P > 0.05)。然而,在义齿清洁剂中浸泡后,只有 L* 组分显示出统计学意义上的显著 ∆E (P = 0.002),但程度轻微。此外,G1DW 和 G1PD 的 ∆E 也有显著差异,G1PD 的变化更大(P = 0.007)。在 G1PD 中观察到浸泡后表面粗糙度明显增加(P = 0.017),G1DW 和 G1PD 之间差异明显。结论:义齿清洁剂对义齿表面的清洁具有重要作用:结论:义齿清洁剂有可能改变热塑性聚酰胺树脂的特性。结论:义齿清洁剂有可能改变热塑性聚酰胺树脂的特性,需要进一步研究探讨这些观察到的变化对义齿性能的临床影响。

Effect of Denture Cleanser on the Physico-Mechanical Properties of Injection-Molded Thermoplastic Polyamides Denture Base Material: A preliminary Study.

Objectives: This study aimed to assess the color stability, surface roughness, and flexural properties of the injection-molded thermoplastic polyamide Vertex ThermoSens denture base resin following a 3-minute immersion in Polident 3-minute denture cleanser.

Methods: Sixty specimens (Vertex ThermoSens) were processed and divided into two main groups (n = 30) based on the type of test. Group 1 was further subdivided into two subgroups (n = 15): the control group immersed in distilled water (G1DW) and the test group immersed in Polident cleanser solution (G1PD). Group 2 was divided into three subgroups: a non-immersed group (G2None), a group immersed in distilled water (G2DW), and a group immersed in Polident cleanser solution (G2PD). Color change (∆E) and surface roughness measurements were conducted for group 1, and flexural modulus (E) test was performed for group 2. The CIE Lab* formula was utilized to calculate ∆E. An optical 3D surface analyzer and a three-point bending test were employed for surface roughness and E assessments, respectively. Data were subjected to statistical analysis using a paired-sample t-test for differences within each group before and after immersion. Furthermore, independent-sample t-tests and one-way ANOVA were conducted to analyze differences between groups. A significance level of P < 0.05 was considered.

Results: The results revealed a slight, statistically insignificant (P > 0.05) ∆E in all color components (L*, a*, b*) after immersion in distilled water. However, after immersion in the denture cleanser, only the L* component exhibited a statistically significant ∆E (P = 0.002), which was slight in magnitude. Additionally, a significant difference was found in the ∆E between G1DW and G1PD, with G1PD showing a higher change (P = 0.007). A significant increase in surface roughness after immersion was observed in G1PD (P = 0.017), with a notable difference between G1DW and G1PD. However, the E remained unaffected (P = 0.537).

Conclusion: Denture cleansers have the potential to modify the properties of thermoplastic polyamide resin. Further research is needed to explore the clinical implications of these observed changes on denture performance.
