A comprehensive diagnostic procedure is performed in order to gain a clear understanding of the specific anatomical and prosthetic characteristics of the case and to identify the best treatment plan.
Impression and wax
bite registration: The anatomy of the patient’s mouth is reproduced (traditionally by taking an impression) and, if necessary, a temporary prosthesis is designed. This process facilitates the manufacture of a radiographic template based on a diagnostic wax-up and enables subsequent digital alignment of the models by means of CT imaging. The impression may also be taken digitally by means of an intraoral scanner.
This is made by the laboratory, on the basis of the impression taken. It is important to check that it fits the patient properly.
Once the radiographic template has been placed in the patient’s mouth, a CT scan is carried out to assess the site and check if it is suitable for an implant.
STL file sent
Exchange of information, between doctor and laboratory, to kick off the planning of the case. The other files to be used are the “stl” that are obtained by scanning the model complete with the radiological template.
The dental technician designs the surgical template on the basis of the detailed 3D scans, in STL format, of the master model (the arch on which the procedure is to be carried out); the antagonist model (the other arch); the master model with Evobite (can be avoided if a double CT scan is done or in the case of partial edentulism with stable teeth); and the master and antagonist occluded.
This is carried out using user-friendly software to calculate the position of the implant so that it is suitable for the prosthesis. In this phase, the type of implant is also selected. This is the first time that the dentist has access to both the medical information and the technical dental information.
of surgical template
The 3D-printed surgical template provides a guide that is fully compatible with the implant system to be used and with the clinic’s surgical planning.
The surgical template is fitted in the patient’s mouth, after which the implant site can be prepared using the guided instruments (specific surgical kit) and the implant can be fitted.
