Changes in Outcome Evaluation before and after Wearing New Complete Dentures

目的：随着日本老龄人口的增加，临床医生期望提供高质量的治疗以改善患者的生活质量。本研究的目的是评估新义齿植入前后的结果变化，并阐明其原因。方法：选择35例患者，在征得知情同意后戴全口义齿。以咀嚼功能评分、满意度评分、支持组织评分为评价因素。在全口义齿治疗的三个阶段进行评估：新义齿植入前(旧义齿)、新义齿植入后首次就诊(首次就诊)和就诊后1个月(1个月)。得分变化采用单因素方差分析、t检验和相关系数分析。对影响患者咀嚼功能和满意度的因素进行了详细分析。结果：在咀嚼功能方面，当“旧义齿”的得分较高时，戴入后的得分下降较大。从戴旧义齿到第一次戴义齿，满意度逐渐提高，到1个月时满意度进一步提高。满意度的变化与满意度因子“上颌义齿的适合性”和“下颌义齿的舒适性”之间存在显著的相关性。咀嚼功能的变化与满意度的变化也有显著的相关性。结论：对新义齿植入前后的结果变化进行了评估，并明确了原因。在旧义齿效果良好的情况下，新义齿的效果有下降的趋势。满意度因素“上颌义齿的适合性”和“下颌义齿的舒适性”被认为是新义齿植入后的关键因素。

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.
