The objective of this study was to use patient-reported outcome to explore patient characteristics that influence the oral health-related quality of life of post-implant patients.
The study design was a nested case-control study. The target population was patients who had undergone implant treatment at the Department of Oral Implantology, Osaka Dental University, with a superstructure fitted ≥ 3 months previously. The survey period was from April 2014 to the end of October 2016. Oral health-related quality of life was evaluated using the General Oral Health Assessment Index (GOHAI). The relationship between patient characteristics and oral health-related quality of life was investigated by binomial logistic regression analysis. The Japanese GOHAI norm for the 50s and 60s age groups was used as the dependent variable for comparison with this study population. Explanatory variables were age, sex, time of survey, implant site, type of superstructure, pre-implant number of molar occlusal support zones, pre-implant deficit status, and number of missing teeth.
Of the total of 1,967 subjects, data were missing for 176 subjects, the time of survey was < 3 months since fitting of the superstructure for 1,021 subjects, and 123 subjects did not meet the inclusion criteria. Therefore, 647 subjects were finally analyzed. As a result of implant treatment, 64.5% of subjects exceeded the Japanese GOHAI norm for the same age group (52.2). From logistic regression analysis, patient characteristics that were extracted as influencing oral health-related quality of life were age < 65 years (odds ratio: 1.8); women (odds ratio: 1.8); and 1 pre-implant molar occlusal support zone (reference value of 4 zones) (odds ratio: 2.5).
This study showed that implant treatment is an effective method for dental prosthetic treatment from the perspective of patient-reported outcome. In addition, patient characteristics that influence the oral health-related quality of life of post-implant patients were shown to be age < 65 years, women, and one pre-implant molar occlusal support zone. This study may help to predict posttreatment oral health-related quality of life and determine treatment plans.
本研究的目的是利用患者报告的结果来探索影响种植术后患者口腔健康相关生活质量的患者特征。
本研究设计为嵌套病例对照研究。目标人群是在大阪齿科大学口腔种植科接受种植治疗且上部结构安装时间≥3个月的患者。调查期为2014年4月至2016年10月底。使用一般口腔健康评估指数（GOHAI）评估口腔健康相关生活质量。通过二项逻辑回归分析研究患者特征与口腔健康相关生活质量之间的关系。将50多岁和60多岁年龄组的日本GOHAI常模用作因变量，与本研究人群进行比较。解释变量包括年龄、性别、调查时间、种植部位、上部结构类型、种植前磨牙咬合支持区数量、种植前缺损状况和缺失牙数量。
在总共1967名受试者中，176名受试者数据缺失，1021名受试者的调查时间距上部结构安装时间<3个月，123名受试者不符合纳入标准。因此，最终分析了647名受试者。种植治疗的结果显示，64.5%的受试者超过了同年龄组的日本GOHAI常模（52.2）。通过逻辑回归分析，被提取为影响口腔健康相关生活质量的患者特征为年龄<65岁（比值比：1.8）；女性（比值比：1.8）；以及种植前1个磨牙咬合支持区（参考值为4个区）（比值比：2.5）。
本研究表明，从患者报告的结果来看，种植治疗是一种有效的牙修复治疗方法。此外，影响种植术后患者口腔健康相关生活质量的患者特征为年龄<65岁、女性和种植前1个磨牙咬合支持区。本研究可能有助于预测治疗后的口腔健康相关生活质量并确定治疗方案。
