Bioclear HD Anterior Matrices, like traditional Bioclear Anterior Matrices, allow for a modern approach to composite dentistry but are stiffer than traditional matrices, and so, are easier to place. They have all of the same advantages of traditional Bioclear Anterior Matrices, including predictable restoration or change of a tooth’s emergence profile; a shape which allows for injection/placement of composite into the embrasure without fear of leaving an overhanging margin; a mylar finish which leaves the interproximal composite smooth and properly contoured; and a shape that creates firm stabilization and full marginal seal when seated into the sulcus which make them easy to use wedge free when closing small spaces with a full contact. The Bioclear Anterior HD matrices are for closing large black triangles where there is still a contact between the teeth, they are not for closing full diastemas where there is no contact present
