Australian-Made Self-Curing Stela Composite for Dental Restorations

Australia: Developed through a collaboration between Specialist Dental Innovations (SDI) and several renowned Australian institutions, including the University of New South Wales, the University of Sydney, and the University of Wollongong, a new self-cure composite called Stela has emerged as a promising solution for various types of dental restorations. 

Stela Primer: An Integral Component 

At the core of Stela’s technology is the Stela Primer, an integral component of the composite system. Unlike traditional curing light-initiated polymerization at the occlusal surface, the Stela Primer enables the polymerization process to commence at the restoration interface. This novel approach, as highlighted in a press release, aims to reduce stress levels, thereby mitigating the risks of marginal gaps, postoperative sensitivity, and restoration failure.

Stela’s placement process involves a two-step approach, with the application of the Stela Primer followed by the restorative material. The traditional composite workflow of etching, priming, bonding, and light curing is reportedly significantly simplified. As a result, Stela can be efficiently placed in as little as 15 seconds, saving valuable chair time for both dentists and patients, says a press release.

The Science Behind Stela

Stela utilizes a snap set process, effectively transforming monomers into a sophisticated network of cross-linked polymer chains. This unique formulation enhances the binding of fillers, which is said to result in a composite material with exceptional compressive and flexural strengths. Available in a single universal shade with chameleon capabilities, Stela is able to blend with the surrounding dentition, for improved aesthetic results.

According to SDI, the composition of Stela includes fluoride, calcium, and strontium, offering additional benefits beyond restoration. Both the Stela composite material and Stela Primer incorporate the 10-MDP (10-Methacryloyloxydecyl Dihydrogen Phosphate) monomer, known for its ability to enhance bond strengths to dentin and enamel.

Additionally, the composite exhibits high radiopacity, aiding in the identification and evaluation of restorations. Stela is available in both syringe and capsule delivery systems, accommodating various clinical preferences.
