Different Types of Matrices for Tooth Restoration

Caries is an infectious diseases which causes decay of the tooth structure. It causes decay of the outer harder tooth enamel, middle softer dentin tissues and inner blood vessels. Later, it can also spread the infection to other organs of the body. Thus, it is essential to prevent the condition and also acquire a proper treatment. There are different types of matrices which are used for the caries restoration. Read on to know more.

  1. Matrices for Class I cavity (compound cavity):

    • Double banded Tofflemire
  2. Matrices for Class II

    • Single banded Tofflemire
    • Ivory matrix No. 1
    • Ivory matrix No. 8
    • Black’s matrices
    • Soldered band or seamless copper band matrix
    • Automatic matrix
    • Auto-matrix
    • S-shaped matrix band
    • T-shaped matrix band
  3. Matrices for a cavity preparation for amalgam on distal of cuspid:

    • S shaped matrix
    • Tofflemire
  4. Matrices for Class III for tooth colored restorations:

    • Transparent celluloid strips
  5. Matrices for Class IV for tooth colored restorations

    • Celluloid strips
    • Aluminum foil (non-light cure)
    • Transparent crown form matrices
    • Anatomic matrix
    • Modified S shaped band of copper, tin, aluminum foil (non-light cure)
  6. Matrices for Class V amalgam restorations:

    • Windows matrix
    • S shaped matrix
  7. Matrices for Class V tooth colored restorations

    • Anatomic matrix (non-light cure)
    • Aluminum or copper collars (non-light cure)
    • Celluloid strips (light cure)
  8. Sectional matrices with G- rings (retainers) for posterior composites.

Matrices:

Matrices used for tooth restoration and preventing caries. Matricing is the procedure whereby a temporary wall is created opposite to axial walls, surrounding areas of tooth structure that were lost during preparation.

Objectives of Matrices:

The matrix should achieve the following functions:

  • Displace the gingival and rubber dam away from the cavity margins. This improves the accessibility during the restorative procedures.
  • Assure dryness and non-contamination of the operating field.
  • Provide shape to the restoration during setting of the restorative material.
  • Maintain shape during hardening of the restoration.

The above article discusses briefly about the different types of matrices used for tooth restoration and objectives of matrices.
