GAP Australasian-Dentist-May June 2019

Category 76 AustrAlAsiAn Dentist similar to the tooth enamel, 6-10 as compared to ceramics that is more resistant to wear than tooth enamel and can cause the wear of the antagonist. 15,16 the aesthetic achieved with the composites is similar to the ceramics, albeit it requires more maintenance, consisting in periodical polish. nonetheless, the advantage of the composite is that it is easier to repair and allows to repair small fractures in mouth without having to remove the restoration and to repeat the aesthetic covering of the entire restoration or part of it. With lithium disilicate crowns cemented over the framework, it is easy to repair too, changing, only, the broken crown. Another aspect of the bonded composite to be taken into account is that it can absorb up to 30% of the occlusive impact transferred to the implants, 15-18 reducing thus the risk of peri-implantitis when gingival inflammation appears around implant-prosthesis connection. 11-14 if dentists want to use ceramic over carbon fibre framework to maintain aesthetic results easier than composite and keeping the same properties of the carbon fibre, Di Franco 20 and Castorina 19 showed the new technique cementing lithium disilicate crowns on the carbon fibre framework. Currently our experience with CFrC is very successful, but, nonetheless, more studies are still needed to ensure its long-term stability and strength.
