Thanks to Dr. Christine Hildebrand for sharing her favourite product - The FenderWedge by Garrision Dental Solutions.
Here is what the website has to say about their product:
Conservative Class II preps are great for saving tooth structure, but can make the placement of your Composi-Tight® sectional matrix bands difficult. FenderWedge will lend you a hand by "pre-separating" the teeth while you prepare the tooth. When the prep is done, remove FenderWedge and slide your Composi-Tight band into place.
As a fantastic added bonus, the firm stainless steel shield protects the adjacent tooth from inadvertent contact with the bur. Again, protecting valuable natural tooth structure while saving you the hassle of having to polish out nicks.
Here's what Denistry Today has to say about Sybron's "Elements" Obturation Unit:
The Elements Obturation Unit combines SybronEndo's System B technology with a motor-driven extruder handpiece to make obturation efficient, predictable, and accurate. The system includes a nonglare tilt screen, a long-life battery, autoclavable cords, and visual and audio signals. Extruder cartridges are available with either Resilon or gutta-percha.
