[Application of maxillary wings guiding plate in rehabilitation of combined defects of maxilla and mandible].
OBJECTIVE
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.
