Dental implants are expanding their use among partially edentulous patients. However, whether implants can promote the quality of life (QOL) of these patients has not been sufficiently examined.
This study compared the QOL level among implant denture, removable partial denture, and no restoration patients with distal extension type unilateral mandibular edentulism.
Three groups (n = 12 each) of subjects with unilateral mandibular distal-extension edentulism who were matched for age, sex, and missing teeth were studied. The groups were (1) implant denture, (2) removable partial denture, and (3) no restoration. QOL levels of these 3 groups were compared using a self-administered questionnaire with 3 major subscales: oral condition, general condition, and dental treatment.
The implant denture group showed higher oral condition related QOL score than the other groups. There was no significant difference in oral condition-related QOL scores between the removable partial denture and no restoration groups. There was no significant difference in the general condition related QOL score and dental treatment-related score among the 3 groups.
In unilateral mandibular distal extension edentulous patients, oral-condition-related QOL levels for dental implant patients were higher than those of removable partial denture or no restoration patients. The QOL levels of the removable partial denture patients were almost identical to those of no restoration patients.
牙种植体在部分牙列缺损患者中的应用正在扩大。然而，种植体是否能提高这些患者的生活质量（QOL）尚未得到充分研究。
本研究比较了种植义齿、可摘局部义齿和未修复的单侧下颌远中延伸型牙列缺损患者的生活质量水平。
研究了三组（每组n = 12）单侧下颌远中延伸型牙列缺损的受试者，他们在年龄、性别和缺失牙方面相匹配。这三组分别为：（1）种植义齿组，（2）可摘局部义齿组，（3）未修复组。使用一份自我管理的问卷比较这三组的生活质量水平，该问卷有三个主要子量表：口腔状况、一般状况和牙科治疗。
种植义齿组在与口腔状况相关的生活质量得分上高于其他组。可摘局部义齿组和未修复组在与口腔状况相关的生活质量得分上没有显著差异。三组在与一般状况相关的生活质量得分和与牙科治疗相关的得分上没有显著差异。
在单侧下颌远中延伸型牙列缺损患者中，种植牙患者与口腔状况相关的生活质量水平高于可摘局部义齿患者或未修复患者。可摘局部义齿患者的生活质量水平与未修复患者几乎相同。
