중증 근무력증 환자에서 폐구 인상법을 이용한 임플란트 피개의치 수복 증례 = Implant overdenture with closed impression technique for patient with Myasthenia Gravis: A case report

다국어 초록 (Multilingual Abstract)

In patients with myasthenia gravis, it is difficult to manufacture and maintain dentures because the muscles and nervous system in the oral cavity are not properly adjusted. In addition, excessively extended or thick dentures may cause muscle weakness by stimulating the muscles, so dentures should be manufactured in consideration of this. In this case, a denture was fabricated using the closed mouth technique in a patient with myasthenia gravis with mouth opening limitation. Using the closed mouth technique, the patient’s masticatory pressure and muscle movements were reproduced and denture with good retention were manufactured.

국문 초록 (Abstract)

중증 근무력증을 가지고 있는 환자의 경우 구강 내 근육 및 신경계가 적절히 조정되지 않아 의치 제작 및 유지가 어렵다. 또한 과도하게 확장되거나 두꺼운 의치는 근육에 자극을 주어 근무력 증상을 유발할 수 있으므로 이를 고려하여 의치 제작을 해야 한다. 본 증례에서는 개구 제한을 가진 중증 근무력증을 가진 환자에서 폐구 인상법을 이용하여 의치를 제작하였다. 폐구인상법을 이용하여 환자가 가지고 있는 저작압 및 근육의 움직임을 재현하고 이를 통해 구강 기능 운동시 구강 내 근육에 자극이 적고 적절한 유지와 안정을 갖는 임플란트 유지 피개의치를 제작하였다.
