Digital Versus Conventional: Denture Tooth Bond Strength Put to the Test

Study explores four denture production processes. Find out which one yields thehighest denture tooth load bearing capability.  

Advances in digital production processes and materials now offer laboratories exciting new options for the efficient production of a removable prosthetic. Laboratories can mill a denture from a single monolithic material with the denture base and tooth material in one single disc; mill the denture base and denture teeth separately in a two-disc process and bond them together; or 3D print the base and bond conventional carded denture teeth. Each of these three digitally driven workflows and production processes reduces production time versus the conventional analog denture fabrication process, but are they equal?

With the IPS Ivotion™ Denture System, complete dentures are milled from one disc using one uninterrupted milling process, reducing the need for manual work from the laboratory technician. With a streamlined clinical workflow, the dental clinician easily prescribes digital dentures all while reducing patient appointments and chair-time.

As new processes become standard of care, it is critical to understand the properties of strength, modulus and bond of these materials.   A recent study conducted by research experts examined eight full arch lower dentures processed from four processing methodologies and then put them to the test to see which yielded the denture teeth with the highest load bearing capability.
