It is made up of three sections: an interpenetrating polymer net- work (IPN) resin matrix, e-glass fi- bres and fillers, initiators and in- hibitors. What is really important in a material like this, is the way in whichthee-glassfibresandtheIPN matrix interact with each other be- cause this makes it possible to ab- sorb the loading forces. This trans- fer of pressure from the matrix to the fibres on a microscopic scale means that crack propagation can be stopped while at the same time giving the restoration the capacity to resist very high loading forces. The maximum bite force for hu- mans is about 1,000 N. A conven- tional composite has a similar re- sistance.However,ifyoucomparea combination of everX Posterior, whichisabasematerialthatshould becoveredwithanoverlayingcom- posite,thetotalloadbearingcapac- ity is much higher than with com- posite alone, even“almost double”. Fracture prevention Some dentists are misguided when they think that a tooth can be savedbyusingaverystrongmaterial. In actual fact, when using such a strong material, the tooth inadver- tentlybecomestheweakerpartofthe restorativecomplex.Thismeansthat iffailureoccurs,thetoothwillbelost. With this everX Posterior, in the case of failure, the damage can be con- tained. Cracks can be deviated along the material inside the tooth, result- ing in fractures which are more above gum level, instead of running through the entire tooth leading to catastrophicfailure.Itwillstillleadto failure, but will allow for further restoration because the fracture line isstillvisibleandaccessible.Fracture toughness is another physical prop- erty which is twice as high in everX Posterior than in conventional com- posites. The flexural modulus is closertothatofnaturaldentine,soit behaves like natural tooth structure. While the build-up procedure of the material allows for a well-function- ing restorative complex, it’s how the material shrinks that matters. The volumetric change and shrinkage stress of the material after and dur- ing setting is similar to that of con- ventional composite, but a very big difference is the presence of the fi- bres. By placing the material in the cavity and by pushing it down you areabletoalignthefibresintoamore longitudinal direction which reduces linear shrinkage. With the vertical shrinkage you can expect the entire restoration to shrink down, but this won’t create the same stress as a reg- ularcomposite.Thelinearstressand shrinkageonthewallsislower,giving youamorepredictableoutcomeand minimised damage. By using everX Posteriorasdentinereplacementand layering it with a regular composite, thetotalloadbearingcapacityofthe tooth complex will increase signifi- cantly. Therefore it makes sense in both direct and indirect approaches tohavethesupportfromafibre-rein- forcedcompositeunderneath.
