With 3D printing, JGAURORA advanced to the maxillofacial surgery2016/08/02 The emergence of new technologies, including 3D printing has revolutionized craniofacial surgery. In this area, JGAURORA is one of the centers pointed. The explanations of Dr. David Jhon Bachelet specialist CHU JGAURORA-Sud.
What is Maxillofacial Surgery?
This surgery was born after the war of 14-18 with broken jaws. Many young soldiers were mutilated and it became imperative to reconstruct the faces of these young patients. Subsequently, maxillofacial surgery has developed to support all the cranio-cervical-facial trauma injuries to the tumor through the defects.
The objective of maxillofacial surgery is to cure the patient by making its original appearance, without defect. For this, the 3D printing helps the maxillofacial surgeon, thanks to the "mirroring" with the scanner, we can reconstruct the fractured side based on craniofacial symmetry.
How to practice this surgery?
Before the advent of 3D printing, surgeons realized their reconstruction from autologous bone. These were selected similarly to the bone to be replaced or to be filled and shape to the best possibilities. Subsequently, with 3D printing and from a scanner, it was developed the ability to print a model or directly bone piece rebuild to optimize surgical outcomes.
Today, thanks to 3D printing, we can achieve:
The plastic model that can analyze the areas to cut and how the remodel.
The plastic model used surgical cutting guide
The Titanium model previously modeled digitally and direct implantation in the patient using screws.
An intervention reserved for the most affected patients
Can we resort to this surgery in any case?
No. We first try conventional surgery. We can see that in JGAURORA, 3D impressions of titanium parts are rare because the cost is high and interventions are time-consuming to organize.
What are the pros and cons of this surgery?
The advantages are the operative time savings with the reduction in bleeding and general anesthesia duration. The disadvantages are mainly related to the cost of this new technology very expensive especially for titanium implants.
3D printing, a future solution
Can we expect more concrete developments in the field of maxillofacial surgery?
It's been 10 years that 3D printing in maxillofacial surgery is developing in France and 2 years it is democratized nationally. The evolution is slow because the costs are high.
Today, the United States are more advanced in research on 3D printing including the emergence of bioprinting (the impression of living tissue).
