赝复体修复Ⅴ类上颌骨缺损的临床效果

Clinical effect of prosthesis on type Ⅴ maxillary defects

目的探讨金属卡环与弹性卡环联合固位式赝复体在上颌骨肿瘤术后Ⅴ类骨缺损修复的临床效果。方法对2012年1月~2015年12月中山大学孙逸仙纪念医院口腔科23例患者,共24副金属卡环与弹性卡环联合固位式上颌骨赝复体进行6个月~2年的跟踪随访。结果佩戴赝复体后,23例患者颌面外形均明显改善,其中,21例洼田饮水试验从Ⅳ级或Ⅴ级改善至Ⅰ级或Ⅱ级,差异有统计学意义(P<0.05);15例可使用患侧咀嚼软食或中等硬度食物;佩戴赝复体前后语音清晰度分别为(36.6±5.6)%和(83.2±7.3)%,差异有统计学意义(P<0.05);18例口腔及赝复体卫生状况维持良好。结论金属卡环与弹性卡环联合固位式赝复体修复上颌骨肿瘤术后Ⅴ类骨缺损可取得良好临床效果,有利于提高患者术后生活质量和心理健康。

Objective To investigate the clinical efficacy of prosthesis retained by metal clasp and flexible clasp in the repair of typeⅤmaxillary defects after tumor resection.Methods23maxillary tumor surgical patients were selected in this study and restored with maxillofacial prosthesis.Total24prosthesis combined with metal clasp and flexible dentures were followed up for half a year to2years.Results After the application of prosthesis,better maxillofacial appearances are presented in all of the patients,Watian drinking water tests are improved to gradeⅠorⅡfrom gradeⅣorⅤin21patients,there was significant difference(P<0.05);Soft diet can be masticated on affected side in15patients;The mean speech intelligibility score with and without prosthesis were(83.2±7.3)%and(36.6±5.6)%,there was significant difference(P<0.05);Favorable hygienic situations of oral cavity and prosthesis are maintained in18patients.Conclusion Prosthesis combined with metal clasp and flexible denture performed favorable clinical efficacy and contributed to improve the living quality and mental health after tumor resection.
