To investigate the relationship between mandibular ridge form, stability and retention of mandibular complete denture, accuracy of jaw relation recording, patients' perception of chewing ability, satisfaction with dentures and oral health-related quality of life (OHRQoL) in complete denture wearers.
A total of 183 edentulous patients, who visited the Dental Hospital of Tokyo Medical and Dental University for new complete dentures, were recruited. Oral examination was performed. Cawood and Howell's method was used to grade the mandibular ridge form. The stability and retention of the mandibular complete denture were assessed using Kapur method. Accuracy of jaw relation recording was evaluated using a newly developed jaw relation index. Patients' perception of chewing ability was rated using a food intake questionnaire. Patients' satisfaction with complete dentures was assessed on a 100-mm visual analogue scale. OHRQoL was measured using the Japanese version of the Oral Health Impact Profile for edentulous subjects. A structural equation model was constructed based on the hypothesis that oral condition and denture quality would be related to chewing ability, satisfaction and OHRQoL.
Significant relationships were found between mandibular ridge form, stability of mandibular complete denture, accuracy of jaw relation recording, perceived chewing ability, satisfaction and OHRQoL. Various fit indices were within acceptable limits.
Oral condition and denture quality were related to patients' perception of chewing ability, satisfaction with dentures and OHRQoL in complete denture wearers.
A favourable oral condition and denture quality are important for successful complete denture therapy.
探讨全口义齿佩戴者下颌牙槽嵴形态、下颌全口义齿的稳定性和固位力、颌位关系记录的准确性、患者对咀嚼能力的感知、对义齿的满意度以及与口腔健康相关的生活质量（OHRQoL）之间的关系。
共招募了183名无牙颌患者，他们前往东京医科齿科大学牙科医院制作新的全口义齿。进行了口腔检查。采用Cawood和Howell方法对下颌牙槽嵴形态进行分级。使用Kapur方法评估下颌全口义齿的稳定性和固位力。使用新开发的颌位关系指数评估颌位关系记录的准确性。使用食物摄入问卷对患者的咀嚼能力感知进行评分。在100毫米视觉模拟量表上评估患者对全口义齿的满意度。使用无牙颌受试者口腔健康影响概况的日语版本测量OHRQoL。基于口腔状况和义齿质量与咀嚼能力、满意度和OHRQoL相关的假设构建了结构方程模型。
发现下颌牙槽嵴形态、下颌全口义齿的稳定性、颌位关系记录的准确性、感知的咀嚼能力、满意度和OHRQoL之间存在显著关系。各种拟合指数在可接受范围内。
口腔状况和义齿质量与全口义齿佩戴者对咀嚼能力的感知、对义齿的满意度和OHRQoL相关。
良好的口腔状况和义齿质量对于成功的全口义齿治疗很重要。
