Digital dentures or 3D printed dentures

What is a digital denture?

The two largest companies offering digital dentures right now are Pala dentures and AvaDent.  They can be 3D printed or CAD CAM.

Why digital dentures?

One big reason is that the denture can be monolithic instead of an acrylic plate with teeth set into it. This greatly increases the strength.

3D printing and milling in theory should create the most accurate fit.  The hold up is still getting a digital impression of the soft tissue, especially in the movable areas.  Lee JPD 2017 has a case report showing how the use of PIP paste and ZOE cement helps increase the software’s ability to stitch.

Research on digital dentures

Pack and press, pour, injection and CAD-CAM were compared using AvaDent to check for accuracy.  Overall the CAD CAM was the most consistent, but not in all areas.  Goodacre 2016 JPD

The fit of CAD-CAM denture bases have better retention than heat-polymerized denture bases according AlHelal 2017 JPD.

Teeth movement is most accurate with CAD-CAM monolithic teeth according to Goodacre 2018 JPD.
