Outline of Final Research Achievements

It prescribed the capacity of the required balloon for impression of maxillary defect by measuring the change of the intraoral capacity of the maxillary defect.The experiment model was modeled with 3D printer using the intraoral 3-D data and CT DICOM data. The expansion method of the balloon inserted the basket catheter using the guide wire in the balloon inside and tried a method to expand the balloon by support from the inside of the basket catheter. It was possible to expand or shrink the balloon easily and quickly.
This study was able to contribute to development by the novel maxillofacial impression system that it was possible for with a nasal cavity and maxillary sinus safely by reducing a balloon again, and removing it after having recorded the complicated intraoral form of the maxillary defect patient.
