Model­preparation
For the fabrication of an IPS e.max Press Abutment Solutions restoration, a model with gingiva mask is fabricated.
– Select the suitable model analog according to the implant system used.
– Fabricate a model with gingiva mask.
Selecting­a­Ti­base
The following paragraphs outline the selection criteria for a suitable Ti base. As a general rule, the instructions of the
respective manufacturer regarding the use of the Ti base have to be observed.
– Only bases consisting of Ti or Ti alloys must be used.
– Select a Ti base with a size that matches the clinical situation and the chosen implant system. The geometry
requirements must be observed.
– The rotation lock must be designed in such a way that stress concentrations on the pressed object are avoided.
– Ti bases with undercuts, e.g. retention grooves, are suitable to some extent.
– Check the available space for the pressed object taking the geometry of the Ti base into account on the model (e.g.
silicone key).
– Observe the instructions of the manufacturer when modifying the Ti base.
