Patent ID: 8382475

Claim:
A method for controlling a position of at least one bore bushing fitted into a drilling template before drilling at least one hole into a patient's jaw bone, the drilling template being located out-side a patient's mouth during the controlling, the controlling comprising: assigning a measurement plane to a reference seat; positioning the drilling template with the at least one bore bushing fitted therein on the reference seat such that the drilling template is distanced from the measurement plane and is held at at least one of a predetermined orientation and a predetermined distance with respect to the measurement plane; measuring or determining an angle position of the at least one bore bushing with respect to a first defined coordinate system or a derived angle position of the at least one bore bushing with respect to a second defined coordinate system, the measuring or determining performed at a distance from the at least one bore bushing by transferring the angle position or the derived position to the measurement plane, wherein the transferring of the angle position or the derived angle position is performed by guiding a respective measurement pin through the at least one bore bushing, applying a reference point to the measurement plane, the reference point designating a position at which the respective measurement pin guided through the at least one bore bushing is to meet the measurement plane, when the at least one bore bushing is introduced at the correct angle position into the drilling template; and contacting the measurement plane with the respective measurement pin and comparing a contact point of the respective measurement pin with the measurement plane to the reference point at the measurement plane.
