To evaluate overdentures with regard to artificial restoration of oral function following mandibular cancer.
We examined 32 patients who had undergone mandibular bone resection as treatment for malignancy and were using implant-supported overdentures. The patients were aged 55-87 years (mean=68.6) with a male to female ratio of 23:9. Marginal resection was performed in 29 patients and segmentectomy in 3.
Before and after using the attachment for overdenture, oral function differed significantly. After the setting of implant-retained overdentures, maximum bite force increased on average by 362% (average, from 16.2 N to 58.8 N; p<0.01). Xylitol gum examination showed a 363% increase in masticatory performance (average, 3.1 to 8.0 points; p<0.01).
Implant-retained overdenture resulted in improved oral function, that was lost after treatment for mandibular cancer.
评估下颌骨癌后采用覆盖义齿进行口腔功能人工修复的效果。
我们检查了32例因恶性肿瘤接受下颌骨切除并使用种植体支持覆盖义齿的患者。患者年龄在55 - 87岁之间（平均68.6岁），男女比例为23:9。29例行边缘性切除，3例行节段性切除。
使用覆盖义齿附着体前后，口腔功能有显著差异。种植体固位覆盖义齿安装后，最大咬合力平均增加362%（平均从16.2 N增至58.8 N；p<0.01）。木糖醇口香糖咀嚼测试显示咀嚼性能提高了363%（平均从3.1分提高到8.0分；p<0.01）。
种植体固位覆盖义齿可改善下颌骨癌治疗后丧失的口腔功能。
