Using Multiple Matrices for Esthetic Enhancement:
A Case Presentation
Author: Arthur R. Volker, DDS, MSc, MSEd, FAGD
Introduction:
In operative dentistry, the purpose of a matrix is to act as a shape former and facilitate the placement of a restorative material. Matrices
are often specific to a particular surface of a tooth, such as the interproximal or cervical. To maximize results, matrices can be combined.
This article demonstrates a clinical case whereby a Bioclear matrix was combined with a Mylar strip to restore a maxillary lateral incisor.
Case Presentation:
The patient was a 37-year-old female in good overall health. Approximately seven years ago, direct polychromatic composite veneers were
placed on #7-10. Following a five-year absence from the office, the patient returned to address a fracture at #10. To restore the interproximal
area, a Bioclear matrix (BT, Bioclear) was used. To veneer the remainder of the tooth, a standard Mylar strip was tucked into the sulcular
area and a microfilled composite (Renamel, Cosmedent) was injection-molded and shaped to complete the restoration.
