Radiology in planning

Digital information repair of Maxilla.

• The main planning problem in bone grafting, when we generate the 3D surface from CT pictures and no included the information what we want to see.

• Those patients which have bone atrophy, in their case the cortical bone of maxilla is too thin. This factor is which affects the contrast quality of image.

• In this case the solution is to reduce the value of voxel (resolution increases).

• This causes better image, because more information coming from the bone (voltage signal proportion of filled) and better the process of voltage signal proportion (raw data).
