下颌牙槽嵴重度吸收的帕金森无牙颌患者修复一例

A case of restoration of Parkinson's edentulous jaw patient with severe absorption of mandibular alveolar ridge

目的:通过生物功能性修复系统(下文简称为吸附性义齿,Biofunctional Prosthetic System,BPS)结合种植体辅助固位修复下颌牙槽嵴重度吸收的帕金森无牙颌患者。方法:通过种植导板辅助33、43位点种植体植入,利用电子面弓的Jaw Relation功能、Articulator功能以及肌电功能,辅助获取帕金森无牙颌患者准确的颌位关系,完成上颌吸附性义齿修复+下颌locator基台辅助固位的种植覆盖义齿修复。结果:上下颌全口义齿戴入后,口内检查、咬合力测试和电子面弓肌电测试均显示出,在面型恢复等美观方面及发音、固位、咬合等功能方面获得良好的修复效果。结论:通过电子面弓Jaw Relation功能、Articulator功能、肌电功能的使用有助于获得帕金森无牙颌患者准确的颌位信息;种植体与BPS相结合的方法有助于牙槽嵴重度吸收的无牙颌患者获得兼具美观和功能的全口义齿。

Objective:To use a Biofunctional Prosthetic System(BPS)combined with implant assisted retention to repair severely absorbed mandibular alveolar ridge in Parkinson's edentulous patients.MethodsMethods:Implantation at positions 33 and 43 was assisted by implant guide plates.The Jaw Relationship function,Articulator function,and electromyography function of electronic facial arch were used as assistance to obtain accurate mandibular position of Parkinson's edentulous patients,then to complete maxillary BPS repair and implant overdenture restoration with mandibular locator base assisted retention.Result:After the denture was inserted,intraoral examination,bite force test,and electronic facial arch electromyography test all showed good repair results in terms of facial restoration and other aesthetic aspects,as well as pronunciation,retention,and bite functions.Conclusion:The use of electronic facial arch Jaw Relationship function,Articulator function,and electromyographic function can help to obtain accurate jaw position information for Parkinson's edentulous patients.The combination of implants and BPS can help edentulous patients with severe alveolar ridge resorption obtain a complete denture with both aesthetics and functionality.
