Today, the underlying innovation is becoming increasingly reliant on new computer-based tools for capture, design, and production processes.
Methods:
1) 3D capture. We propose to work from the virtual reconstruction of patient's face. The RX scanner can be used to model the patient's skin and underlying bone structure in case we want to predict the implants placement. Furthermore, a 3D optical camera can be used to get a better definition of the skin surface and the macroscopic lenses give unprecedented accuracy. The main advantage of this technique is that it saves our patient from an uncomfortable facial imprint while disclosing only pertinent information.
2) Designis carried out by using CAD software. Initially, the virtual epithesis is used as an actual layout director defining the position of the various implants. The volume of all implants and their connectors are placed in the prosthesis beforehand while taking into account the bone volume as well as any anatomical barriers. This helps meet the aesthetic imperative. Following this study, another element can be modeled, namely, the surgical guide to assist the surgeon's hand during the implant phase in accordance with the prosthetic project.
3) Productionresorts to numerically controlled machines. The implantation guide can be made of machined or sintered metal. It complies with current sterilization requirements for the operating room. The physical model of the epithesis is printed by a machine using castable wax and flasked for the injection of silicone.
Results:
This technique avoids difficult facial impresssion and the morphology of the epithesis is more faithful. In addition, manufacturing is faster.
Conclusions:
As a result, new protocols have been integrated within the multidisciplinary team including prosthesis, surgeon and radiologist. Our technique has many advantages that can solve some problems of the conventional technique
