上颌骨缺损伴张口受限的磁性附着体分段式赝复体修复

Magfit-attachment-linked sectional obsturator and prosthesis for maxillary defects and placket restrained

目的探讨上颌骨缺损伴张口受限患者应用磁性附着体连接分段式赝复体修复的临床特点和疗效。方法选择15例上颌骨缺损患者,其中8例伴有张口受限。依据术后修复时间及张口情况分别选择磁附着体连接分段式赝复体和一体式中空赝复体进行修复,测定咀嚼效率、进行语音清晰度评价和临床效果评价。结果使用磁性附着体连接分段式赝复体可使上颌骨缺损伴张口受限病人提前进行修复,而且分段式赝复体摘戴方便,固位稳定,发音得到良好的改善,美观也有一定恢复。磁性附着体连接分段式赝复体咀嚼效率高于一体式中空赝复体(P<0.05),两类赝复体和语音清晰度评价没有差别(P>0.05)。结论上颌骨缺损伴张口受限患者,应用磁性附着体连接分段式赝复体修复能达到比较满意的效果。

Objective To evaluate the clinical effects of rehabilitation with a magfit-attachment-linked sectional obturator prosthesis for maxillary defect and placket restrained. Methods The magfit-attachment-linked sectional obturator prosthesis was applied to treat 8 patients with maxillary defect and placket restrained. The integrative hollow obturator was for other 7 patients with maxillary defect only. The masticatory efficiency and speech intelligibility were measured respectively, and the clinical effect of prosthesis was reflected individually. Results The sectional obsturator joining by dental magnetic attachment could make the patients with maxillary defects and placket restrained rehabilitate. Wear- ing the obsturator improved stabihty and achieved clear pronunciation, the masticatory eficiency and speech intelligibility. Conclusion To apply the magfit-attachment-linked sectional obturator prosthesis in maxillary defects and placket restrained can achieve perfect effect.
