After I finish the treatment of the second premolar with direct composite restoration the patient came again after 6 months later to treat the first premolar but this time he chose the indirect restoration, treatment was the old composite removed, D.M.E with new composite restoration with tokuyama LX5 , Ever x posterior for dentin replacement, biobase created, finished and polished, impression, indirect lithium disilicate overlay
Initial situation of upper first premolar, you remember the second premolar that treated with direct composite before 6 months ago
Old composite removed, D.M.E with tokuyama composite, Ever x posterior for dentin replacement ,biobase
Always do macro build up in premolars , for extra retention as the bonded area smaller than the area in molars
Cementation day
Isolation, sandblast you can see the effect of sandblast on the biobase
Teflon tape on the adjacent teeth , etching and bond without curing on the biobase after sandblast, cementation with heated composite
Immediate result occlusal view
Palatal view you can see the fitness
Another view
Fitness in the buccal view
