摘　　要：目的　探讨舌形态及功能运动与下颌总义齿稳定性的关系。方法　总结 15 7例牙槽嵴中、重度萎缩的下颌总义齿修复病例 ,其中正常舌 139例 ,肥大舌 11例 ,巨舌症 2例 ,后缩舌 5例。通过制作带有舌定位柄的个别托盘 ,限定舌运动范围 ,取好合适的舌印模位 ;测定垂直距离时 ,前蜡堤稍有间隙而不接触 ,平面以下颌为基准 ,排牙时先排下颌 ,最后确定下颌牙合平面在正常息止位时 ,位于舌侧缘下 2～ 3mm。结果　初戴和戴后 1月、6月、1a进行复查 ,148例病人均能使用义齿 ,舌活动自如 ,舌与义齿比较协调 ,发音好、讲话清楚 ,义齿在口腔中不移动 ,功能恢复满意。 3例肥大舌、2例巨舌症、2例后缩舌、2例下颌骨牙槽嵴重度萎缩者 ,粘膜薄易破损 ,修复后效果不理想。Objective To explore the relationship between contour and functional movement of tongue and stability of complete mandibular denture. Methods 157 patients with middle to severe alveolar atrophy restored with complete mandibular denture were retrospectively reviewed. Of the patients, 139 cases had normal tongue, 11 had hypertrophic tongue, 2 had macroglossia and 5 had retrusive tongue. An appropriate impression position of tongue was obtained with limitation of lingual movement by individual tray with tongue orientation bar. In measurement of the vertical distance, the anterior wax rim did not contact with a small space. The mandible was used as the standard plane. The mandibular denture was first arranged. The occlusal plane of the mandible was 2 3mm inferior to the lingual margin at rest.Results The patients were reexamined 1 month, 6 months and 1 year after rehabilitation with denture. 148 patients used the denture with satisfactory results. The tongue was mobile freely in accordance with the denture. Unsatisfactory results were present in 3 patients with hypertrophic tongue, 2 patients with macroglossia, 2 patients with retrusive tongue and 2 patients with severe mandibular alveolar atrophy.Conclusion The anatomic morphology and functional movement of tongue play an important role in the stability of the mandibular complete denture.
