jIn restoration of teeth, the use of conventional matrix bands and wedges tends to leave gaps or spaces which can through inefficient restoration lead to fracture or infection, and also prove to be time consuming and inefficient. This invention addresses shortcomings of conventional restorative devices by providing an easy to use dental tool that has a first member and a second member with struts that adjust to fit into the proximal box, and that provides a predictably tight contact area for optimal tooth restoration.
