Webinar: "Fibre reinforced composites strengthening large direct restorations", S. Browet

www.gceurope.com In this webinar, Stephane Browet shows us why and how to use the fibre reinforced composite everX Posterior from GC for letting the clinical images talk for themselves. No more cracked tooth with this fibre reinforcement! Failure of restorations has a dual reason: the behavior of the material and the fact that the material and the tooth do not work well together. The final objective of the restoration is the preservation of the tooth. Using the correct material and correct preparation design, it is aimed to stop crack propagation and to prevent crack development. It is desirable that the restorative material is adhesively bonded rather than mechanically retained, that is has mechanical properties similar to tooth structure, with low polymerisation stress and a high load-bearing capacity and resistance to fatigue. EverX Posterior is the material that meets these expectations. It can reliably be bonded to any overlaying composite as well as to the tooth substance. The resin matrix forms an interpenetration polymer network in which e-glass fibres and glass fillers are embedded. There exists a good bonding and integration between the fibres and this matrix, so that the fibres can take over the stress that is formed into the matrix, which is key to its ability to prevent and stop crack propagation and thus avoid ‘cracked tooth’. The load bearing capacity of indirect restorations using short random fibre reinforced composite as a base is twice as high as composite alone. Finally, a protocol for restoring big cavities in posterior teeth is proposed and tips and tricks on how to create a good contact point between the proximal areas are given.
