“Our intention was to evaluate whether dental students accept the 3D-printed surgical training model just as well as the popular typodont model.”

“We also present an evaluation of the model by dental students and compare it with their evaluation of the conventional typodont model,” the team wrote. The model they created is of a real patient’s upper jaw with three anterior root apices, periodontal ligament, and the apical granuloma, along with a gingival mask. Therefore, we have developed a method to create more realistic, individualized training models,” the researchers explain. Anatomical variations, such as extremely long or even curved roots, cannot be simulated with these industrially produced models. “The teeth used are idealized stereotypes. The researchers explained that the typodont model at their university features teeth “in direct contact with the hard plastic that simulates the jawbone,” and simulates the inflammation (apical granuloma) with wax, though it’s missing a sensitive periodontal ligament.

“Furthermore, the ready-made standard models do not usually depict special pathological or anatomic situations,” they wrote.Ī root tip resection, or apicoectomy, removes inflammation around the tip of the tooth’s root. Then, they compared them against a commercial typodont model, which is a common simulation model used at university dental clinics with replaceable gingiva masks and teeth that often “show idealized eugnathic situations, which are rarely encountered in everyday practice.” A group of researchers from University Hospital Münster in Germany published a paper on this topic, relaying the results of their work using real patient data to create 3D printed surgical training models for root tip resection.

That’s why I’m always glad to hear stories of dental students using 3D printed training models to learn on – if they have to work in my mouth, then I want them to know what they’re doing. There are few things I hate more than going to the dentist.
