To determine how patients and dentists in Japan value the outcomes of different treatment options for missing molars.
Elderly removable-denture wearers and dentate persons (senior group), preclinical dental students (young group), and prosthodontists were presented with five possible treatment options for missing lower bilateral first and second molars. The participants indicated on a visual analogue scale how they would value the treatment (utility value: UV), if they had received each of the treatments. Two-way repeated measures anova was used for statistical analyses.
The UV for the shortened dental arch (SDA) without replacement was the lowest in every group. The young group rated the value of cantilever fixed partial dentures (FPD) and implants significantly higher than removable partial dentures (RPD), while the senior group rated the value of FPD and RPD significantly higher than implants. Those having experience with removable dentures were likely to place a higher value on the acrylic RPD. The prosthodontists rated the value of implants significantly higher than any other options.
The participants in every group placed the lowest value on the outcome from the SDA in Japan. The denture wearers preferred the RPD, while prosthodontists preferred implants.
确定日本的患者和牙医如何看待缺失磨牙的不同治疗方案的结果。
为老年可摘义齿佩戴者和有牙列者（老年组）、口腔临床前学生（青年组）和修复科医生提供了五种治疗缺失双侧下颌第一和第二磨牙的可能方案。参与者在视觉模拟量表上表示，如果接受了每种治疗，他们将如何重视治疗（效用值：UV）。采用双向重复测量方差分析进行统计分析。
在每个组中，不修复的缩短牙弓（SDA）的 UV 最低。青年组对悬臂固定局部义齿（FPD）和种植体的价值评价明显高于可摘局部义齿（RPD），而老年组对 FPD 和 RPD 的价值评价明显高于种植体。有可摘义齿经验的人可能会对丙烯酸 RPD 给予更高的评价。修复科医生对种植体的评价明显高于其他任何选择。
每个组的参与者对日本 SDA 的结果给予的评价最低。义齿佩戴者更喜欢 RPD，而修复科医生则更喜欢种植体。
