General preparation guidelines

SuccessfulresultscanonlybeachievedwithIPSe.maxifthepreparationguidelinesbelowandtheminimumlayerthicknessesarestrictlyobserved.

For the preparation of all-ceramic restorations, the following principles apply:– Noanglesoredges– Shoulderpreparationwithroundedinneredgesand/orchamferpreparation

ForCAD/CAM-fabricated restorations,theincisaledgeofthepreparationshouldbeatleast1.0mm(millingtoolgeometry)inordertopermitoptimummillingoftheincisalareaduringCAD/CAMprocessing.

The dimensions indicated in the paragraphs below reflect the minimum thickness for IPS e.max restorations.
