At a dental meeting I recently had the opportunity to try out the new light cured temporary crown and bridge material Radica, from Dentsply. The temporary bridges looked great and appeared to be very strong. According to the rep from Dentsply, Radica is much stronger than most other comparable materials and is better for long term temporary bridge usage. The only downside was that it takes 30 minutes to fully cure Radica in a Triad oven – if I understood the rep. I’m wondering what others experience has been with Radica and if it and how it has proven beneficial for practice?
According to Dentsply:
“The provisional restoration plays an important role in maintaining the esthetic and functional aspects of a patient’s dental health, and has a significant impact on the final restoration placement as well. Provisional restorations are also being used for longer service terms, as the use of implant therapy becomes more popular. Current options, direct and indirect, suffer from material and process limitations, giving rise to concerns about wear in service, durability, load-bearing capability, or esthetics.
Radica is a new system for provisional and diagnostic restorations from DENTSPLY Ceramco. Based on a visible light curing (VLC) composite platform, Radica has been developed to exceed the performance criteria of currently available restorations.
The use of a composite material as a provisional is not novel in and of itself. However, the process to fabricate these is cumbersome, and involves layering build-ups 9-1 1. The Radica system offers a unique solution by using a shape stable visible light
cured composite material as a basis…Radica provides enhanced strength, durability, and wear resistance, with a significant improvement in esthetics over current provisionals. The capability to efficiently layer enamel and dentin materials, in combination with characterization, provides for excellent patient satisfaction when serving as both a diagnostic and a provisional restoration.
Additional Benefits of Radica include:
*Provides a Life-Like tooth-colored diagnostic for case presentation
*Offers the optimum in a low-wear, highly durable material for long-term provisional restorations
*Delivers premium high-end esthetics to your patients as they transition to their fixed restoration
*Yields excellent strength for confidence in performance
The Provisional Process with Radica
To receive a customized provisional restoration, practitioners forward impressions of unprepared teeth to a trained dental laboratory, using VPS materials such as Aquasil Ultra Smart Wetting Impression Material. After preparing a model from this impression (Step 1), the laboratory may create a matrix out of quick-setting silicone. Next, warmed Radica enamel resin is extruded into the incisal area. Warmed Radica dentin is then extruded into the dentin area of the matrix (Step 2). The
matrix is now adapted to the model. The shape-stable Radica resin cools into the exact contours determined by the lab ( Step 3). This resin may be added to, adapted, tried in or easily modified in its wax-like uncured state (Step 4). The resin is light and heat-cured with a glaze-like sealer in a variety of processing units: the Eclipse®, the Enterra™ or the Triad® VLC Light Curing Units. The restoration may be characterized using effect dentins and stains. The laboratory delivers the finished provisional to the dentist.”
