Matrix Retainer
A Dental Matrix Retainer is mechanical used to secure the ends of a matrix band around a tooth. The band provides a substitute wall where a part of the tooth is missing and helps to compact a restoration into a prepared tooth cavity after the carious lesion has been removed. Usually by engaging the ends of the matrix band and drawing the band tight. When a restoration involves an interproximal surface, it is not possible to achieve a properly adapted restoration without a matrix band. A matrix band creates a temporary interproximal surface, and, when appropriate, a matrix retainer secures the matrix band in place.
Function of matrix
- To confine restorative material while it is hardening.
- To established optimal contacts and contours for the restoration.
- To prevent gingival overhangs off restoration.
- To provide acceptable surface texture for restoration.
