Hi everyboy ,
Has anybody made a custom abutment made of e.max ? Thanks
Has anybody made a custom abutment made of e.max ? Thanks
I don't know any specifics but my rep mentioned in a recent email new ingots due out in 2012. In addition to the multi ingots there will be new ingots for the "NEW e.max Press Abutment". I would have to assume if this is for fab. custom abutments they would have to be pressed to a prefab interface, like the two part Zr abutments.
Are you going to press over a titanium base? How will it be bond to the metal?
How will you mask the grey showing through the translucent ceramic?
Will it be screw retained or cementable?
Hi, just thought I would mention this while you are considering doing an abutment in Emax. Remember that emax, like all other all ceramic materials including zirconia, will undergo a phase change over 5 years in the oral environment. This will result in up to 50% reduction in flexural strength. Therefore you can imagine that your abutment may only have 200mpa after the phase change. Do you think this is strong enough? Remember the failed alumina abutments we all did in early procera abutments, and they had a starting flexural strength of 600 mpa. Food for thought??
But there will still be a screw access hole to insert the crown/ abutment?
I wish we could press zirconia.....watch Mark show us a secret pic
