摘要
目的评价软衬材料在一侧上颌骨缺损修复中的应用及临床效果。方法6例一侧上颌骨缺损患者,每例患者同时制作软衬式阻塞器修复体和传统硬质树脂阻塞器修复体各1副,分别作为试验组和对照组。比较两组在修复体的固位稳定性、口鼻腔封闭作用及语音清晰度等方面有无差别。结果试验组修复体在固位稳定性、口鼻腔封闭作用方面均优于对照组修复体,试验组和对照组的语音清晰度分别为(90.4±6.7)%和(84.2±5.1)%,差异有统计学意义(P<0.01)。结论软衬材料应用于一侧上颌骨缺损早期修复,能在术后早期恢复患者的生理功能,增加修复体的固位稳定性,改善语音清晰程度。
Objetive To evaluate the effect of soft lining material used in early maxillary obturator prostheses, Methods Six patients with maxillary defect were included in this study, Each patient was provided with a resilient obturator prosthesis and with a hard obturator prosthesis as an in self-paired control, The retention and stability, oro-nasal seal, speech intelligibility （SI） of the two kinds of prosthesis were compared. Results The retention and stability, Oronasal seal of the resilient obturator prostheses were better than those of the hard obturator prostheses. The mean SI score with a resilient obturator prosthesis was 90.4% ± 6.7% and was 84.2% ± 5.1% with hard obturator prosthesis （ P 〈 0.01 ）. Conclusion The use of soft lining material in the early restoration of maxillary defects can improve retention and stability, oro-nasal seal, speech intelligibility.
