Aesthetic restoration of posterior teeth using different occlusal matrix techniques

Abstract

The occlusal matrix technique appears as an alternative to the conventional restorative technique. The aim of this study is to present treatment options for the decayed occlusal surface of posterior teeth by means of an occlusal matrix made with different materials, for an accurate reproduction of the tooth surface. This paper presents five clinical cases using five different materials, such as Bite-Perf, flowable composite, self-curing acrylic resin, silicone and thermoforming foil. Before light-curing, the last layer of composite resin, the matrix, is repositioned and firmly pressed so the replication of the original occlusal anatomy can be achieved. When using an occlusal matrix, minimal or no finishing and polishing procedures are needed and the offered aesthetics are clearly an advantage. Moreover, this technique makes up for the additional chairside work time. The occlusal matrix technique is demonstrated to be effective for direct composite resin restorations in posterior teeth, allowing a reliable and predictable reproduction of the occlusal anatomy and clinical adjustment. For this purpose, a clear material is preferable since it allows light transmission.

Key points

  • Discusses advantages and disadvantages of different materials to make the occlusal matrix.

  • Emphasises the importance of a smooth surface when restoring teeth.

  • Compares the conventional restoration technique with the occlusal matrix technique.
