Abstract

This case report presents a closed hollow bulb obturator made by 3D printing for a maxillectomy patient. Final impression was taken according to the instructions and impression trays provided by the Magic $denture^{TM}$ system. Vertical dimension, facial appearance, and retention had been checked with the try-in denture. The try-in denture was corrected and adjusted to fulfill the demand of the patients, then these were reflected to the final design of the denture. The defect area was designed as a closed hollow bulb shape to reduce the weight and to provide uniform thickness of the denture. The patient satisfied with the esthetics and function of the denture.

본 증례는 상악골 결손이 있는 무치악 환자에서 3D printing을 이용해 closed hollow bulb obturator로 수복한 증례이다. Magic $denture^{TM}$ 시스템(Cozahn, Seoul, Korea)에서 제공하는 트레이와 인상법을 이용하여 구내 인상을 채득하였고, 시적의치상에서 수직고경과 안모, 유지력 등을 확인하였다. 환자가 요구하는 바와 오차를 시적의치에서 수정한 후 이를 반영하였다. 의치의 무게를 줄이고 균일한 두께를 부여하기 위해 상악골 결손부위를 closed hollow bulb로 디자인하여 최종의치상을 프린팅하였다. 치료 후 심미적 및 기능적으로 만족스러운 결과를 얻었기에 이를 보고하는 바이다.
