Changes in Outcome Evaluation before and after Wearing New Complete Dentures

目的：随着日本老年人口的增加，临床医生有望提供高质量的治疗，以提高患者的生活质量。本研究的目的是评估结果的变化之前和之后，安装新的义齿，并澄清causes.Methods：35例患者佩戴全口义齿后，获得知情同意。以咀嚼功能评分、满意度评分和支持组织评分作为评价因素。在全口义齿治疗的三个阶段进行评估：插入新义齿（旧义齿）之前，插入新义齿后的第一次访问（第一次访问）和插入后一个月（1个月）。采用方差分析、t检验和相关系数分析评分变化。结果：在咀嚼功能方面，当“旧义齿”评分较高时，戴入后评分下降幅度较大。从旧义齿到第一次就诊，满意度增加，并在1个月时进一步增加。此外，满意度的变化与满意度因素“上颌义齿适合度”及“下颌义齿舒适度”有显著相关。咀嚼功能的变化与患者满意度的变化也有显著相关性。结论：通过对患者戴用新义齿前后咀嚼功能的变化进行评价，明确了其原因。在旧义齿效果良好的情况下，新义齿的效果有下降的趋势。结论：上颌义齿的适合度和下颌义齿的舒适度是影响患者戴用新义齿后满意度的主要因素。

Purpose : As the aged population in Japan increases, clinicians are expected to provide high-quality treatment to improve patients' QOL. The purpose of this study was to evaluate the change of outcome before and after insertion of new dentures and to clarify the causes.Methods : Thirty-five patients wearing complete dentures were selected after obtaining informed consent. Chewing function score, satisfaction score and supporting tissue score were used as the assessment factors. These were evaluated at three stages in complete denture treatment : before insertion of new dentures (old denture), first visit after insertion of new dentures (1st visit), and one month after insertion (1 month). Changes in scores were analyzed with ANOVA, t-test and correlation coefficient. Factors for evaluating chewing function and satisfaction were analyzed in detail.Results : In chewing function, when the score of "old denture" was high, the score after insertion decreased greatly. Satisfaction increased from old denture to 1st visit, and increased further at 1 month. In addition, there were significant relationships between the changes in satisfaction and the satisfaction factor "fit of the maxillary denture" and "comfort of the mandibular denture". There was also a significant correlation between the changes in chewing function and the changes in satisfaction.Conclusion : The changes in outcome were evaluated before and after inserting new dentures and the causes were clarified. In case of the good outcome of old denture, the outcome of new denture tended to decrease. The satisfaction factors "fit of the maxillary denture" and "comfort of the mandibular denture" were suggested to be the key factors after insertion of new dentures.
