Finishing
It is of critical importance to use the correct grinding instruments for finishing and adjusting the IPS e.max CAD ceramic
structure. If unsuitable grinding instruments are used, chipping of the edges and local overheating may occur (please
observe the Ivoclar Vivadent Flow Chart "Recommended grinding tools for PS e.max glass-ceramics").
Basic notes regarding the finishing of IPS e.max CAD
– Carry out adjustments by grinding of IPS e.max CAD restorations while they are still in their pre-crystallized (blue) state, if
possible.
– Only use suitable grinding instruments, low speed and light pressure to prevent delamination and chipping at the
margins in particular. Overheating of the glass-ceramic must be avoided.
– During finishing, make sure that the minimum layer thicknesses are observed.
– Cut the ceramic structure from the block using a diamond separating disc. Slightly scratch the attachment area at the
incisal side of the abutment and separate the attachment point from the basal.
Checking the fit of the ceramic structure on the Ti base
– Carefully place the ceramic structure on the Ti base and check the fit. Observe the position of the rotation lock.
