According to GlobalData’s company profile on Dentsply Sirona, AI-assisted medical imaging was a key innovation area identified from patents. Dentsply Sirona's grant share as of June 2024 was 59%. Grant share is based on the ratio of number of grants to total number of patents.

The granted patent US12042549B2 outlines a photopolymerizable resin composition specifically designed for the production and repair of dental prosthetic and restorative articles. The composition consists of 45% to 70% by weight of one or more first polymerizable acrylic compounds, which are urethane di or multi(meth)acrylate derivatives of 1,3-bis(isocyanatomethyl)cyclohexane. Additionally, the formulation may include a reaction product of a diisocyanate end-capped pre-oligomer intermediate compound with hydroxyalkyl(meth)acrylate compounds. The weight ratio of the first to third polymerizable acrylic compounds is specified to be between 5:1 and 20:1, and the composition is limited to no more than 10% by weight of photopolymerization initiators.

Further claims detail the physical properties of the resin composition in its cured form, emphasizing its mechanical performance. The composition is required to exhibit a Flexural Stress of at least 90 MPa, a Flexural Modulus of at least 2300 MPa, a Fracture Toughness (Kmax) of at least 0.90 MPa-m1/2, and a Work of Fracture (Wf) of at least 90 J/m2, as measured according to ISO 20795-1:2013 standards. Additionally, it should demonstrate a Localized Wear Volume Loss of no more than 0.15 mm3. The inclusion of polymerization inhibitors in the range of 0.01% to 0.5% by weight is also noted, along with a viscosity limit of 50,000 cP at 25°C in its uncured state. This comprehensive formulation aims to enhance the durability and performance of dental materials used in restorative applications.
