Dental Students to Train on Lifelike Mouth Models

Dentistry Today


Dental models with the tactile qualities of real mouths will be used to train the next generation of dentists thanks to new research carried out in collaboration with the University of Birmingham School of Dentistry

A joint project by Michael Milward, BDS, PhD, and Paul Cooper, PhD, at the school and PhD candidate Richard Arm of Nottingham Trent University (NTU) will allow student dentists to experience and learn how it feels to use periodontal probes to check for gum disease.

Funded by the University of Birmingham’s Alumni Impact Fund, the models feature realistic gums as well as tongues, which feel and behave like the real thing. These models are designed for students to learn how to examine the mouth safely and check for disease.

Made from synthetic gels and fibers, the tongue and gums vary in hardness to mimic living tissue while the teeth and jawbones are made from bone-simulating resin.

“These models meet an unmet need in dental education and will allow us to better prepare our students for clinical work,” said Milward, reader and honorary consultant in clinical periodontology at the University of Birmingham. 

“The feedback we have received from students and staff has been extremely positive, and the final version has already been introduced into undergraduate teaching. While some models are commercially available, no models combine the replica hard and soft tissues in this way to provide a realistic learning experience,” said Milward. 

“These developments provide a major step forward in dental education, both for dental students and for the retraining of the dental workforce, ultimately benefitting our patients,” said Milward. “We aim to work closely with our colleague at Nottingham Trent University to further enhance the models to allow our students to develop additional clinical skills.”

“The aim is to give students the psychological experience of how it feels to perform real dentistry, but in a safe learning environment,” said Arm of the Advanced Textiles Research Group at NTU’s School of Art & Design.

“These realistic models will allow students to learn the tactile skills of how to examine the gums and teeth before examining their first patients,” said Arm.

“Until now, current dental models haven’t provided a realistic enough experience for students, and the inclusion of a tongue will mimic the challenge which dentists face and better prepare them for their first clinic,” said Arm.

Students and staff at the School of Dentistry have provided feedback on prototype dental training models to inform the final design.
