コンピュータ支援外科と歯科用コーンビームCT

抄録

Computer assisted surgery (CAS) starts from surgical simulation. Then it progressed to surgical navigation system. The major technical components of CAS were registration, tracking, segmentation, and modeling. The volumetric CT image data plays important role in the whole process of CAS. CAS utilized various surgeries including maxillofacial region. While in the field of dentistry, the typical use of CAS was dental implant. There were several unique simulation / navigation systems that specialized to dental implant. The advent of arm-type cone beam CT (CBCT) has paved the way for the general dentists to use CAS. However in compare with medical surgery, CAS based on dental CBCT has several disadvantages. These were in the reproducibility of CT number and standardization of image data.
