Book Description
Background:The principles of minimal invasion have been developed to preserve tooth structures. The advances in adhesion techniques and new cad-cam restorative materials allow us to perform predictable treatments with partial restorations, leaving aside full-coverage retentive preparations. The preservation of the dental structure, especially of enamel, allows us to perform a reliable adhesive cementation technique. Sometimes, the lack of dental substrate leads to exposure of the dentin layer, which has constituted a handicap for the dental adhesives. The immediate dentine seal allows us to make an adequate adhesion technique and improves the strength of some restorative materials.The aim of this review is to compare the influence of the immediate dentin seal with the conventional adhesive cementation technique by analyzing the fracture resistance of aesthetic CAD-CAM restorative materials of the posterior sector.Materials and Methods Samples of the following materials were made: IPS E.max CADu00ae (Ivoclar Vivadent), VITA ENAMICu00ae (VITA Zahnfabrik) and Lava u2122 Ultimate (3M ESPE). All samples were cemented over exposed dentin. The teeth were treated using the immediate dentin sealing protocol established by Pascal Magne. This procedure consists of etching the dentinal surface for 15 seconds with 37.5% orthophosphoric acid and the subsequent application of the Optibond FLu00ae two-step adhesive agent (Kerr Cop). Each sample wassubjected to a static load test until fracture occurred. The resistance presented by each sample was recorded and analyzed. A statistical study was carried out using parametric testsResults.The cementation technique influences the behavior of dental restorative materials. The resistance values found in this study show that, depending on the luting technique used, fracture resistance of materials increases. With the limitations of the present study, the immediate seal of the dentin shows to be capable of improving the mechanical behavior.Conclusions and Clinical implications.The development of adhesive cementing protocols requires knowing precisely the appropriate treatment for each material and the dental surface where we want adhesion to occur. The cementation technique is capable of influencing the fracture strength of the material, particularly in ceramic materials.
