To investigate the factors influencing patients' willingness to replace removable dentures using structural equation modeling (SEM).
A total of 153 patients who sought consultations for removable dentures self-evaluated denture quality using a visual analog scale (VAS); health-related quality of life using the 36-item Short-Form Health Survey; and oral health-related quality of life using the Oral Health Impact Profile. Dental clinicians evaluated denture quality using a VAS and by assessing the presence of defects. After being informed of various treatments, patients were asked whether they would prefer denture replacement. SEM was applied to analyze the relationships and interactive effects among the variables.
The final model showed high goodness-of-fit indices (chi-square/degree of freedom = 1.009, comparative fit index = 1.000, Tucker-Lewis index = 0.999, standardized root mean square residual = 0.421, and root mean square error of approximation = 0.008). SEM demonstrated that two latent constructs indirectly predicted patients' willingness to replace dentures; the standardized total effects of good oral health and poor denture quality were -0.154 and 0.503, respectively.
These findings provide a unified understanding of the shared decision-making process for denture replacement and highlight the pretreatment assessments that play a relevant role in patient treatment preferences.
采用结构方程模型（SEM）探讨影响患者更换可摘义齿意愿的因素。
共 153 名因可摘义齿前来就诊的患者使用视觉模拟评分（VAS）自评义齿质量；使用 36 项简短健康调查评估健康相关生活质量；使用口腔健康影响程度量表评估口腔健康相关生活质量。牙科临床医生使用 VAS 评估义齿质量，并评估缺陷的存在情况。在告知各种治疗方案后，询问患者是否愿意更换义齿。采用 SEM 分析变量之间的关系和相互作用。
最终模型显示出较高的拟合优度指标（卡方/自由度=1.009，比较拟合指数=1.000，Tucker-Lewis 指数=0.999，标准化均方根残差=0.421，均方根误差近似值=0.008）。SEM 显示，两个潜在结构间接预测了患者更换义齿的意愿；良好的口腔健康和较差的义齿质量的标准化总效应分别为-0.154 和 0.503。
这些发现提供了对可摘义齿更换共同决策过程的统一理解，并强调了在患者治疗偏好中起相关作用的预处理评估。
