Dr. Alejandro Roisentul | Philip Segal MDT

Case Study: Computer guided planning

Implants 45, 46, 47

Digital data collection:

CBCT + Optical scan of plaster models
CBCT taken with open bite

Optical scan of plaster models taken in closed occlusion

Virtual set-up of teeth in accordance with occlusal relationship

Virtual set-up of teeth in accordance with occlusal relationship

Synchronization of model scan to dicom

Perfect alignment
