I.e. the input stage can include CT scans, panoramic X-rays and Status X-rays. In addition, the input can include other clinical images, impressions, intraoral scans and 3D facial imaging. The input may further include pre-operative planning data such as as well as other requests from the patient, such as smile design etc. Finally, a case description can be inserted for future retrieval.

  • the processor 18 can suggest to the user one or more prosthetic setups, in accordance with corresponding plans stored in the database server 15. Alternatively, this step can be fully automated, i.e. the processor 18 determines the required prosthetic setup in accordance with corresponding plans stored in the database server 15. Once the type, size and disposition of the prosthesis is determined, the system defines the implant required for supporting the prosthesis, i.e., the crown restoration.
  • the bite registration with the opposing arch is set, and the amount of required lip support is determined.

These steps can be carried out by the user using the planning software via port 12, or automatically by the processor 18 forming the required views in accordance with corresponding plans stored in the database server 15. Obviously, in case the entire planning process is automated, the step of generating views can be omitted.
  • the patient’s anatomical structures are drawn (block 122), which may include drawing of the nerve canals, blood vessels, and teeth, such that the edge of the implant does not reach the canal or the blood vessels or other teeth.
  • Drawing the nerve canals for example, can be carried out by indicating the edge point of the roots in proximity of site of interest, and by connecting between these edge points.

  • the implant may also be disposed in an angle, such that the minimum distance between the implant and the adjacent root is maintained.
