项目摘要

・ObjectiveVarious types of implant-supported overdentures have been developed as prosthetic treatments for edentulous patients. However, comparison of the treatment outcomes among the complete dentures has not been sufficiently examined, because oral conditions such as denture-supporting tissues differ markedly. Previously, these differences were assessed using X-ray CT and cast measurements, but these techniques are complicated and not widely used.This study compared treatment outcomes of implant-supported overdentures using magnetic and bar attachment with complete dentures using chair-side functional evaluation charts by matching of age, sex, duration of denture usage, and denture-supporting tissues.・MethodsTen patients with implant-supported overdentures (IOD group, mean age : 60.8, sex : 3 men and 7 women, duration of denture usage : 27.0 months) and 35 patients with complete dentures (mean age : 71.7, sex : 15 men and 20 women, duration of denture usage : 38.1 months) participate … More d in this study. First, in both groups, the chair-side functional evaluation charts were used to compare treatment outcomes in relation to (1) complete denture quality, (2) chewing function, and (3) overall satisfaction. Next, ten subjects (CD Group) out of the 35 complete denture patients were selected who were matched for the four items (age, sex, duration of denture usage, and denture-supporting tissues) to the IOD Group. Denture-supporting tissues were quantitatively assessed (0-100) with an examination protocol. Lastly, these scores of CD and IOD groups were compared using the Student's t-test and chi-squared test.・ResultsDenture supporting tissue scores of the 35 complete denture patients and IOD Group were 36.6 vs. 20.0 points. The average fit for the above four items of the 35 complete denture patients and IOD Group was 70.1%.The average fit for the above four items of CD group selected from the 35 complete denture patients (mean age : 65.3, sex : 3 men and 7 women, duration of denture usage : 24.2 months and denture supporting tissue score : 20.1 points) and IOD Group was very good (95.4%).Overall satisfaction scores of the 35 complete denture patients and IOD Group indicated no difference. However, complete denture quality score (93.9), chewing function score (77.0), and overall satisfaction score (80.8) of the IOD Group were higher than those of the CD Group (67.3, 38.5, 54.7) (P<0.05).・ConclusionIn this study, the matching test including an assessment of denture supporting tissue made it possible to compare treatment outcomes of implant-supported overdentures using magnetic and bar attachment with complete dentures. Furthermore, it was clarified that treatment outcomes of the IOD Group were higher than those of the CD Group. Less

各种类型的种植体支持覆盖义齿已被开发作为无牙患者的修复治疗。然而，全口义齿之间的治疗效果的比较尚未得到充分的研究，因为口腔条件，如义齿支持组织显着不同。以前，这些差异是通过X线CT和石膏测量来评估的，但这些技术很复杂，没有广泛使用。本研究通过匹配年龄、性别、义齿使用时间和义齿支持组织，使用椅旁功能评估表比较了磁性附着体和杆式附着体种植覆盖义齿与全口义齿的治疗效果。·方法选择10例种植覆盖义齿患者（IOD组，平均年龄60.8岁，性别3男7女，义齿使用时间27.0个月）和35例全口义齿患者（平均年龄71.7岁，性别15男20女，义齿使用时间38.1个月）作为研究对象 ...更多信息 d。首先，在两组中，使用椅旁功能评价表比较治疗结果与（1）全口义齿质量，（2）咀嚼功能和（3）总体满意度的关系。接下来，从35名全口义齿患者中选择10名受试者（CD组），他们在四个项目（年龄，性别，义齿使用时间和义齿支持组织）上与IOD组相匹配。使用检查方案对义齿支持组织进行定量评估（0-100）。最后，使用Student t检验和卡方检验比较CD组和IOD组的得分。·结果35例全口义齿患者和IOD组的义齿支持组织评分分别为36.6分和20.0分。35例全口义齿患者和IOD组上述4项的平均拟合度为70.1%，CD组35例全口义齿患者上述4项的平均拟合度为70.1%，CD组35例全口义齿患者上述4项的平均拟合度为70.1%，CD组35例全口义齿患者上述4项的平均拟合度为70.1（平均年龄：65.3岁，性别：3名男性和7名女性，假牙使用时间：24.2个月，假牙支持组织评分：35例全口义齿患者的总体满意度与IOD组无显著性差异。但IOD组的全口义齿质量评分（93.9）、咀嚼功能评分（77.0）和总体满意度评分（80.8）均高于CD组（67.3，38.5，54.7）（P<0.05）。结论在这项研究中，匹配测试，包括义齿支持组织的评估，有可能比较种植覆盖义齿使用磁性和杆式附着体与全口义齿的治疗效果。此外，阐明了IOD组的治疗结局高于CD组。少
