Solving complex engineering and chemistry challenges requires balancing several factors simultaneously. The same is true for the components of a 3D printed denture. In the rapidly growing printed denture segment, some manufacturers focus on one material property only or cite data that’s clinically irrelevant.
Experienced dental lab technicians understand that a balance of engineering factors leads to high performance dentures.
The role of a denture base is to provide support for denture teeth, as well as serving as an optimal interface between these and the alveolar bone and gingival tissues. A balance between high impact resistance (defined by Fracture Toughness) and Flexural Strength/Modulus addresses the concerns of patient comfort and denture breakage from dropping or chewing.
Denture teeth require a balance of factors to achieve Wear Resistance, the critical mechanical factor for chewing surfaces.
Expanding the possibilities
Dentsply Sirona leverages over 100 years of denture design and test experience to innovate, test, and validate the optimal balance for its materials.
It is important for Dental Laboratories to have confidence in the expertise behind the materials they use, and the critical balance achieved in these materials, created by teams of scientists and clinical experts, to meet the changing workflows of modern digital dental laboratories.
Dentsply Sirona is pleased to share a small sampling of the extensive testing that leads to the optimal balance for denture bases and denture teeth.
A high impact denture base material can resist the stresses of chewing and the rigors of everyday patient handling without fracturing. Lucitone Digital Print™ 3D Denture Base meets both criteria of a “high impact” denture base.1
Furthermore, it is rigid enough to hold the teeth effectively in position while chewing, and strong enough to provide stability from mastication and irregular resorption of the alveolar ridge.
Lucitone Digital Print has an average of 0.02% residual methacrylate content, an amount much lower than the maximum specification requirement of 2.2%3.
Progressive wear of occlusal surfaces of denture teeth results in insufficient tooth support, causing functional and esthetic impairments, thus reducing the longevity of the denture.
Lucitone Digital Print™ 3D Denture Base and Lucitone Digital IPN accurately reproduce the dimensions of the computer-assisted design with impressive dimensional accuracy measurements:
The dental lab seeks reassurance that the color of the denture base will not lighten nor darken away from the shade prescribed by the dentist, while the patient wants confidence that their denture will maintain the color and smile they prefer. Just as with the denture base, or maybe even more important, denture teeth must also show color stability.
Finally, Lucitone Digital Print™ 3D Denture Base and Lucitone Digital IPN Printed Denture Teeth work seamlessly together to address a major cause for concern of patients, dentists, and lab technicians: denture teeth debonding.
