摘　　要：目的:探讨上颌翼状导板在上下颌骨联合切除术后早期赝复治疗中的应用价值。方法:收集10例因口腔癌根治而切除上下颌骨而未进行同期功能性重建的患者,其中2例术前获得口内牙列印模,8例因术前开口受限而在术后2周获得口内印模。在初步印模基础上制作个别托盘后,取工作模型、咬合记录并上架。利用上颌余留牙设计固位卡环,制作带有翼状导板的腭护板。患者于术后1周开始佩戴。结果:10例患者在术后1～3个月的康复训练后,无饮水返流及鼻漏气,腭咽闭合功能良好,上下颌余留牙咬合关系良好。去除翼状导板后,能够自主咬合,达到最大咬合面积。结论:腭护板联合翼状导板不仅能够保护上颌骨切除术区创口,早期分隔口鼻瘘,而且能够尽早纠正上下颌骨联合切除后的错。为二期永久赝复体制作提供了条件。PURPOSE：To evaluate the role of maxillary wings guiding plate in rehabilitation of combined defects of maxilla and mandible in convalescent stage. METHODS：Combined resection of maxilla and mandible without reconstruction were performed in 10 patients with oral cancers. The impressions were got in 2 patients preoperatively and 8 patients postoperatively because of preoperative limited mouth opening. The clasps were designed to provide the retentive force according to the remained teeth. The plastic palate baseboard with wings guiding plate was made. The patients wore the plate 1 week after surgery. RESULTS：All the patients get good velopharyngeal competence and occlusion without leakage from nose after using this prosthesis for 1 to 3 months. CONCLUSIONS：Palate baseboard combined with wings guiding plate can not only obstruct the nasal-oral fistula but also correct malocclusion. It＇s convenient for taking dental prosthesis in late stage and improving patient＇s quality of life.
