Patient evaluation: surgical template
The surgical template is a device that prefigures both (1) the prosthetic project to enable its visualization on X-rays (radiographic template), and (2) to optimize the implant positioning during surgery (surgical guide). Placement of several contiguous implants often requires a surgical template.
Precision is essential particularly in the esthetic area where even limited inaccuracy can have detrimental consequences. As a result, technical procedures are similar to temporary removable dentures.
Stability avoids any displacement of the template during radiographic examination and surgery. Stability is provided by non-mobile teeth if possible (teeth-borne template; Fig. 19.1) or by the edentulous ridge (soft tissue-borne template; Fig. 19.2).
The template must be easy to use, essentially because patients will wear them during radiographic examination. During surgery, positioning and retrieving the device mus/>
