Resin composite (Spectrum TPH-3) restorations were placed using the following matrices (n=10): a) circumferential straight metal matrix with Tofflemire retainer-A, b) circumferential pre-contoured metal matrix system-B (Adapt SuperCap), c) circumferential pre-contoured transparent matrix system-C (Adapt SuperCap) and d
Describe a class IV restoration . What type of matrix band will be used ? Interproximal surfaces of incisors and canines and incisal edges. Myar matrix bands will be used .
Matrices are placed for interproximal restorations to aid in restoring normal contour and contact areas and to prevent extrusion of restorative materials into gingival tissues. Many types of matrix bands are available for use in pediatric dentistry .
Try the wedge . Use of a wedge with the matrix band serves two purposes: Helps to compress the matrix band against the tooth structure to create a tighter seal, preventing gingival overhang.

A mechanical device designed to hold a matrix band in position on the tooth. Contact ring matrix retainers (trade names: BiTine, Contact matrix , Composi-Tight) have been developed for use with sectional matrices to provide tooth wedging and reduce the need for interproximal wedging.
Use of the T Matrix Band With the No. 110 pliers, bend the flanges of the ” T ” upward (Fig. Fold the T -wings over the circle formed. Hold the band with one finger. Remove the band .
