目的评价中空式赝复体修复上颌骨缺损后的咀嚼效率,为赝复体在临床中的应用提供一定的参考依据。方法对14例不同类型上颌骨缺损的患者进行中空式赝复体修复,采用称重法测定患者赝复体修复前后的咀嚼效率,进行统计学分析。结果 14例患者赝复体修复后容貌、语音及咀嚼等功能有不同程度的提高,戴用赝复体前的咀嚼效率为(42.02±12.67)%,戴用赝复体后的咀嚼效率为(55.84±11.03)%,差异有统计学意义(P<0.05)。结论赝复体修复能封闭口、鼻腔通道,良好地重建固有口腔的形态,提高患者的咀嚼效率。
Objective To evaluate the masticatory efficiency of hollow prostheses in the treatment of maxillary defects and provide some references for the application of prostheses in clinical practice. Methods Hollow prostheses were repaired in 14 patients with different types of maxillary defects. The chewing efficiency of prostheses before and after prosthesis restoration was measured by weighing method, and statistical analysis was performed. Results The appearance, speech and chewing function of the prosthesis in 14 patients improved to some extent. The chewing efficiency before wearing prosthesis was (42.02 ± 12.67)%, and the chewing efficiency after wearing prosthesis was ( 55.84 ± 11.03)%, the difference was statistically significant (P <0.05). Conclusion Prosthetic repair can close the mouth and nasal passages and reconstruct the inherent oral morphology and improve the masticatory efficiency.
