- The Diastema Closure matrices are for creating new and exaggerated emergence profiles, closing diastema larger than 1mm and for large black triangles. - The Diastema Closure matrices have more curvature than the Anterior matrices. Combining papilla regeneration with space closure is the key to optimal diastema closure. - If there is good contact, the matrix is easily used wedge free. - When placed into the sulcus, the matrix is stabilized and marginally sealed by the papilla. - If there is not a contact, then a staged wedging (or delayed wedging) technique will be used. - Bioclear’s anatomically shaped matrices allow for injection/placement of composite into the embrasure without fear of leaving an overhanging margin. - The Bioclear Matrix leaves the interproximal composite smooth and properly contoured. - Comes in 3 models DC201 for mesial sides of upper incisors ,DC202 for distal sides of upper incissors and DC203 for all the sides of small incisors. **For further product information , please contact Chat support**
