Bioclear matrix and injection molding (Intervention group)
maxillary lateral incisors, incisors, tooth, lateral incisors, mandibular incisors
All the upcoming procedural steps using bioclear matrix were performed according to manufacturer instructions. Optimum curvature for gingival embrasure closure was determined by a color-coded gauge and matrices that was corresponding to colors at the top of the matrix as following the gauge entered into the black triangle reveals the curvature to utilize. The matrices are available in two sizes (big and small incisors) and four curvatures, allowing the operator to treat the entire anterior sextant, canine to canine, and both upper and lower arches with robust and aesthetically acceptable results.Black Triangle Matrix Series consists of color-coded matrices that used paired and closes space up to 2.5 mm, these series are available in two dimensions. Small used for mandibular incisors and small maxillary lateral incisors while Large ones are taller wrapping the tooth more than the small incisors matrices, large maxillary lateral incisors matrices, maxillary and mandibular canine matrices.
