- METHOD FOR EXAMINING A DRILLING JIG FOR PRODUCING AN IMPLANT-SUPPORTED DENTAL PROSTHESIS

摘要

The present invention relates to a method for verifying a drilling template (1) for generating an implant-retained tooth replacement before performing an implant drilling (2). The resulting drilling template 1 is placed on the tooth structure 3 of the jaw region 5 to be provided with a tooth replacement. The measuring element 11 is inserted into the drill guide 6 of the drilling template 1 and the at least one partial area of the tooth structure 3 not covered by the measuring element 11 and the drilling template 1 (16) is measured using an optical three-dimensional measurement method. The position and orientation of the measuring element 11 with respect to the partial area 16 of the tooth structure 3 is then determined from the generated measurement data 24 of the optical measurement and the virtual actual implant drilling model 26 Using the position and orientation determined for the measuring element 11 and / or using the known dimensions of the drill to be used, and / or the position of the stop surface 8 on the drilling template 1 for the drill to be used, Data 24 and the actual implant drilling model 26 is compared to the planned virtual target implant drilling model 29 from the pre-implant plan with respect to its position and orientation.
