To examine the effect of mandibular ridge form and denture quality on oral health-related quality of life (OHRQoL) in complete denture wearers by using structural equation modeling (SEM) analysis of data before and after new complete denture insertion.
Four hundred thirty-two edentulous patients who visited the Dental Hospital of Tokyo Medical and Dental University for new complete dentures were recruited. An intervention study design was conducted, including complete denture fabrication with SEM analysis. Mandibular ridge form, mandibular denture stability, accuracy of jaw relation record, and the Oral Health Impact Profile for edentulous subjects (OHIP-EDENT-J) total score before and after new complete denture insertion were used in the hypothesized model.
Two hundred and thirty-seven participants completed the research. SEM analysis demonstrated adequate model fit. Path coefficients of mandibular ridge form to OHIP-EDENT-J before and after insertion, and mandibular denture stability to OHIP-EDENT-J before insertion, were significant.
This study demonstrated that mandibular denture stability and mandibular ridge form are important to ensure successful complete denture therapy.
通过对新全口义齿植入前后数据的结构方程模型（SEM）分析，研究下颌牙槽嵴形态和义齿质量对全口义齿佩戴者口腔健康相关生活质量（OHRQoL）的影响。
招募了 432 名前往东京医科齿科大学牙科医院就诊的无牙颌患者。采用全口义齿制作的干预研究设计，包括 SEM 分析。在下颌牙槽嵴形态、下颌义齿稳定性、颌位记录准确性和无牙颌患者口腔健康影响简表（OHIP-EDENT-J）总分等假设模型中使用了新全口义齿插入前后的指标。
237 名参与者完成了研究。SEM 分析表明模型拟合度良好。下颌牙槽嵴形态对植入前后 OHIP-EDENT-J 以及下颌义齿稳定性对植入前 OHIP-EDENT-J 的路径系数具有显著意义。
本研究表明，下颌义齿稳定性和下颌牙槽嵴形态对于确保全口义齿治疗的成功至关重要。
