– Static and dynamic antagonist contacts must be taken

into consideration.

– The preparation margins must not be located on

centric antagonist contacts.

– Provide at least 1.5 mm of reduction in the cusp

areas.

– Prepare a circular shoulder with rounded inner edges

or a deep chamfer. Width of the shoulder/chamfer

should be at least 1.0 mm.

– Reduce the anatomical shape and observe the

stipulated minimum thickness. Prepare a circular

shoulder with rounded inner edges or a deep

chamfer. Width of the shoulder/chamfer at least

1.0 mm.

– Reduce the incisal crown third by approx. 1.5 mm.

– Reduce the buccal or lingual area by approx. 1.5 mm.

– For conventional and/or self-adhesive cementation,

the preparation must demonstrate retentive surfaces

– Static and dynamic antagonist contacts must be taken

– The preparation margins must not be located on

centric antagonist contacts.

– A preparation depth of at least 1.0 mm and an

isthmus width of at least 1.0 mm must be observed in

the fissure area.

– Prepare the proximal box with slightly diverging walls

and observe an angle of 100°-120° between the

proximal cavity walls and the prospective proximal

inlay surfaces. For inlays with pronounced convex

cavity walls without adequate support by the proximal

shoulder, marginal ridge contacts should be avoided.

– Round out internal edges in order to prevent stress

concentration within the ceramic material.

– Do not prepare slice-cuts or feather edges.
