“Restoring Proximal Contacts of Teeth”

Abstract

Matrices are used whenever one or more walls of the tooth are missing. They help to establish the proper anatomic contour and proximal contacts without gingival overhangs. There are several designs of matrices available for different clinical situations. They may range from a simple metal or plastic strip to a circumferential band of metal encircling the entire crown depending on the extent of tooth destruction.

Anterior Matrix Systems for Composite Restorations: A Review

“…Ideal contact and contour maintains periodontal health, prevents food lodgement, provides support, alignment, and stabilization, self-cleansing, the shelf life of restorations is improved, and maintains the teeth's normal mesiodistal relationship [ 4 ].…”

“…Matricing is the process of constructing a temporary wall that runs in the opposite direction of the axial wall to surround the lost tooth structure [ 4 ]. "Matrix" is a tool that holds the restoration in place in the tooth while it sets [ 4 ]. The word matrix is derived from the Latin word "Mater" which means "Mother."…”

“…It should have ease of application, ease of removal, provide proper proximal contact and contour, and should be cost-effective and confine the restoration [ 4 , 5 ].…”
