The incremental layering technique is very time-consuming, especially when dealing with large cavities. Dentists can now reduce their treatment time by more than half while achieving the same esthetics and function of traditional 2mm layered composites. The new 3s (three second) PowerCure System from Ivoclar Vivadent is key to this improvement in efficiency.
The 3s PowerCure System is comprised of products that are optimally coordinated for direct restorative procedures enabling esthetic, high-quality posterior restorations to be produced with extreme efficiency. The system includes Adhese® Universal (single-component adhesive), Bluephase® PowerCure (intelligent, high-performance LED curing light), and Tetric® PowerFill and Tetric PowerFlow (sculptable and flowable composites which can be placed in increments up to 4 mm). When light-cured from the occlusal surface with Bluephase PowerCure, the adhesive will polymerize in 3 seconds and each 4 mm layer of composite can be cured in just 3 seconds. The extended layer thickness of up to 4 mm significantly reduces the number of treatment steps required.
This is an open system because the adhesive and composites are compatible with other curing lights when cured according to their instructions for use, while the Bluephase PowerCure LED light has a choice of four different levels of light intensity, making it compatible with all other materials.
The highly reactive light initiator Ivocerin has paved the way for the development of Tetric PowerFill and Tetric PowerFlow for esthetic posterior restorations. These composites offer enamel- and dentin-like translucency levels due to Aessencio technology. This enables the same esthetic results in the posterior region as with conventional composites. A patented chain transfer agent provides low shrinkage and increased strength. These proprietary technologies provide efficiency, quality and esthetics like no other.
Bluephase PowerCure is an intelligent curing light that detects unintentional movement of the handpiece during the light-curing procedure. It alerts the user of improper operation by vibrating and automatically extends the exposure time to ensure that the material receives adequate amount of light energy needed for proper polymerization. If the accidental movement prevents the material from curing properly, the light will automatically interrupt the exposure cycle so it can then be repeated correctly
