The continuation of progress in the matter of table tops preparation.
Indications: For the restoration of occlusal tooth defects in the posterior region. A new onlay preparation set for all types of minimally invasive posterior tooth preparations.
During preparation, it should be noted that the adhesive bond to the enamel is considered to be of higher quality than to the dentin. At the same time, the higher modulus of elasticity of enamel compared to dentin stabilizes the ceramic. Therefore, in case of doubt, enamel should preferably be retained and a lower ceramic layer thickness should be realized instead. Under occlusal contact points, the preparation depth should be a maximum of 1.5 mm, taking dynamic occlusion into account.
Due to the high masticatory pressure in the posterior region, we recommend monolithic lithium disilicate (LS2) restorations for conversion to the final occlusal surface onlays. The minimum thickness of 1 mm for lithium disilicate (LS2) table tops should not be undercut.
