Title

Evaluation of cavity size, kind, and filling technique of composite shrinkage by finite element

Pages

  33-39

Abstract

 Background: Cavity preparation reduces the rigidity of tooth and its resistance to deformation. The purpose of this study was to evaluate the dimensional changes of the repaired teeth using two types of light cure composite and two methods of incremental and bulk filling by the use of finite element method. Materials and Methods: In this computerized in vitro experimental study, an intact maxillary premolar was scanned using cone beam computed tomography instrument (SCANORA, Switzerland), then each section of tooth image was transmitted to Ansys software using AUTOCAD. Then, eight sizes of cavity preparations and two methods of restoration (bulk and incremental) using two different types of Composite resin materials (Heliomolar, Brilliant) were proposed on software and analysis was completed with Ansys software. Results: dimensional change increased by widening and deepening of the cavities. It was also increased using Brilliant Composite resin and incremental filling technique. Conclusion: Increase in depth and type of filling technique has the greatest role of dimensional change after curing, but the type of Composite resin does not have a significant role.
