Interdental wedge

The interdental wedge is particularly intended for use in the insertion of approximal fillings of light-curing synthetic materials and consists of a combination of a wedge body and an underlying compressible sole comprising a rim which projects on both sides of the wedge body. The sole portion is preferably made of a thermoplastic elastomer and the wedge body of a translucent synthetic material. A wedge of this kind provides a strong spreading force, and the two rims are deformed when inserted, thereby ensuring a firm retention and a tight application of the matrix to the dental anatomy, and they form sealing lips in order to keep away the saliva from the treated area and to gently displace the papilla.
