Why Need To Use Matrix Band?

Why Need To Use Matrix Band?

1. matrix band is a dental tool used to establish the foundation for a missing proximal wall of a tooth preparation. It can be metal or plastic and is designed to maintain its shape against the tooth walls to support tight contacts during dental procedures.

2. Matrix band is used when doing interproximal restorations. Simply put, its purpose is to keep composite from coming in contact with the adjacent teeth. It forms the interproximal wall. It has concave surface (upward) & one convex (downward). The conxity of matrix band should put on the occluscal surface.

3. The matrix method makes it possible for a digital computer to calculate pressures at many positions of complex high-vacuum systems.

4. The use of matrices in dentistry allows us to reconstruct teeth according to their original morphology, maintaining their shape, contour and contact points, in order to preserve their function. This important task is the responsibility of restorative dentistry, which over time has focused its efforts on the development of new techniques and materials to facilitate this task. 

   
   

   What are the functions of dental matrices?

   Preserve the restorative material, avoiding overhangs.

   Restore the tooth anatomy, helping to reconstruct its contact relationship and lost contour.

   Restore the tooth's biological function and protect the supporting tissues, avoiding injuries.

   Contribute to the surface finish, achieving a non-retentive surface for plaque or food debris.

   Reduce the probability of secondary caries.

   Increase the lifespan of composite restorations.

   Protect the adjacent tooth during a cavity preparation procedure
