Radiographic/Surgical Guides
Radiographic and surgical guides are necessary to properly treatment plan and execute treatment for implant dentistry cases. The design and accuracy of fit of a radiographic guide provide the needed diagnostic information and enable it to be converted to a surgical guide.
Below are examples of various designs.
Radiographic guides used to fabricate a Materialize® surgical guide have specific requirements. For the fully edentulous arch, the denture base and the teeth should contain barium of different concentrations. The guide for the partially edentulous situation will be tooth borne, and only the missing teeth should contain barium.
Surgical guides may be used to obtain an index at the time of implant fixture placement. This permits the abutment and temporary crown to be fabricated and inserted at stage II surgery.
