Area of Science:

  • Restorative Dentistry
  • Dental Materials

Background:

  • Direct resin composite restorations are widely used for posterior teeth.
  • Achieving accurate anatomical form and marginal integrity can be challenging.

Purpose of the Study:

  • To present a new technique for performing direct resin composite restorations on posterior teeth.
  • To introduce the use of a clear acrylic resin matrix for improved restoration accuracy.

Main Methods:

  • A clear acrylic resin matrix is fabricated before tooth preparation.
  • The matrix is used during the placement of resin composite material.
  • It facilitates the reproduction of occlusal and proximal surfaces, including marginal ridges for Class II restorations.

Main Results:

  • The technique allows for fast and accurate reproduction of original tooth anatomy.
  • It aids in achieving proper contour and marginal ridge form.
  • The procedure offers potential advantages in terms of efficiency and aesthetic outcomes.

Conclusions:

  • The described technique offers a viable method for enhancing the quality of direct resin composite restorations.
  • The clear acrylic resin matrix is a valuable tool for replicating complex tooth anatomy, particularly in Class II restorations.
