3D-printing approaches to denture base fabrication and dental education

The use of additive manufacturing (AM) is increasingly growing in Dentistry due to the new opportunities these techniques can offer; these include custom-design, waste materials reduction, incorporation of internal structure and scaling-up possibilities, among others.

Fused deposition modelling (FDM) and stereolithography (SLA) are two of the most used AM techniques in the dental field. Each technique offers its own advantages, for example, FDM is a very cost-effective manufacturing method and SLA allows very high resolution.

At The School of Clinical Dentistry in Sheffield we have been exploring these two fabrication methods in different scientific scenarios. One of our current projects is based on the characterisation of FDM 3D-printed acrylate-based constructs for the manufacture of removable prostheses and we also have a project based on the development of models for dental education, specifically, evaluating the pedagogical value of 3D-printed teaching models. This talk will present our key data and progress in the area of 3D-printing for dental applications for both denture base manufacture and dental education.

A presentation by Ilida Ortega Asencio, Senior Lecturer in Dental Materials and Manufacturing Technologies at The University of Sheffield.


Question 1: What drives you?
My passion in the Biomaterials and Bioengineering fields

Question 2: Why should the delegate attend your presentation?
Because it will be a research-like presentation showing key data we have gathered at Sheffield in the area of 3D-Printing for 2 different and pioneering fields (new approaches to denture base fabrication and the creation of new dental teaching models using an additive manufacturing approach)

Question 3: What emerging technologies / trends do you see as having the greatest potential in the short and long run?
Additive Manufacturing

Question 4: What kind of impact do you expect them to have?
They are having an impact already, from my perspective the impact is huge in both research and teaching scenarios

Question 5: What are the barriers that might stand in the way?
In Dentistry conventional manufacturing is very well-established

About Ilida Ortega Asencio
My research experience is based on the manufacturing, characterisation and in vitro testing of biomaterial devices for tissue engineering applications. I have a bachelor’s degree in Chemistry from The University of Alicante, a Master´s degree in Biomaterials from The University Autónoma of Madrid and I did my PhD in The Institute of Bioengineering at the University of Elche (Spain). Following my PhD I moved to England and I worked for one year as a postdoctoral researcher at the University of Sheffield in a Wellcome Trust funded project. I then secured a competitive EPSRC E-TERM Landscape Fellowship and from the 1st of January 2014 I have been working at The School of Clinical Dentistry in Sheffield, now as Senior Lecturer in Dental Materials and Manufacturing Technologies.

About The University of Sheffield
The University of Sheffield developed from three local institutions: the Sheffield School of Medicine, Firth College and the Sheffield Technical School. The School of Medicine, founded 1828, was by far the oldest. Its early history was very insecure and it was saved from collapse by the opening of Firth College, which took over the teaching of all basic science subjects to medical students.

Firth College was one of a group of university colleges founded in the later 19th century. It developed out of the Cambridge University Extension Movement, a scheme designed to bring university teaching to the large towns and cities of England, most of which lacked any university provision. The success of these courses in Sheffield led Mark Firth, a local steel manufacturer, to establish the College in 1879 as a centre for teaching Arts and Science subjects.

Our vision
We will deliver life-enhancing research, innovation and education that not only transforms the lives of our graduates, but shapes the world we live in. We believe the best way to achieve this is by fostering an ambitious, inclusive, collaborative community.

Ilida Ortega Asencio is speaker at the 2022 edition of the 3D Dental Printing Conference.
