本研究评估了下颌种植支持的口腔修复对无牙老年人咀嚼和吞咽过程中肌电活动的影响。年龄超过60岁的患者15例，其中女性10例，男性5例。所有患者都是无牙列的，在两个牙弓上都戴上了可拆卸的全口义齿，并用种植支持的修复体替换了下颌义齿。所有患者在术前、术后3个月、6个月和18个月，使用不同质地的食物，进行咬肌、口轮匝肌上肌和颧下肌的肌电检查。采用Kruskal-Wallis非参数检验对不同时期的结果进行统计分析。统计学分析显示，只有咬肌有明显的肌电活动丧失(P
This study evaluated the effect of implant-supported oral rehabilitation in the mandible on the electromyographic activity during mastication and swallowing in edentulous elderly individuals. Fifteen patients aged more than 60 years were evaluated, being 10 females and 5 males. All patients were edentulous, wore removable complete dentures on both dental arches, and had the mandibular dentures replaced by implant-supported prostheses. All patients were submitted to electromyographic evaluation of the masseter, superior orbicularis oris muscles, and the submental muscles, before surgery and 3, 6 and 18 months postoperatively, using foods of different textures. The results obtained at the different periods were analyzed statistically by Kruskal-Wallis non-parametric test. Statistical analysis showed that only the masseter muscle had a significant loss in electromyographic activity (p
