AAA.4 Implantation Plan SR Document Dental DriLLING TEMPLATE Example

The following example shows the result of a planning activity for a dental implantation using a dental drilling template. The implant positioning is based on a CT-Scan during which the patient has been wearing a bite plate with 3 markers. In this example the markers (visible in the patient’s CT images) are detected by the planning application. After the implants have been positioned, the bite plate, in combination with the registration information of the implants, can be used to produce the dental drilling template.

In the following example, two implants are inserted which are not assembled using Mating Points.

The markers of the bite plate are identified and stored as 3 Fiducials in one Fiducial Set. This Fiducial Set has its own Frame of Reference (1.2.3.4.100).

The Registration Object created by the planning application uses the patient’s CT Frame of Reference as main Frame of Reference (See Figure F.4-1). [pic]
