Who know any manufacture of EDM? whos the best? Is this process gives incrediable passive fit for bars and screw retained bridges for real?
Promising 5mkm accuracy.
I've contacted reseller. They give analogs for popular implant systems and their screw abutments. Work with Ti and CoCr.That's an interesting concept to finetune fit... wonder what material the analogs are made of
You're going to spend a **** load of money to achieve with a casting what is already done with CAD CAM.I've contacted reseller. They give analogs for popular implant systems and their screw abutments. Work with Ti and CoCr.
point is that it is impossible for milling machine to archive passive fit on 8 implants, bar or multyunits whatever. Milling accuracy linearly decrease with linear dimension.You're going to spend a **** load of money to achieve with a casting what is already done with CAD CAM.
Edm is what we did before cad came along.
I don't see the point.
Not what the research says.point is that it is impossible for milling machine to archive passive fit on 8 implants, bar or multyunits whatever. Milling accuracy linearly decrease with linear dimension.
Of cause it is not about fitting crowns and bridges, cad cam do it much cheaper.
Sources ?Not what the research says.
Your search would be for papers related to passivity of fit in terms of longevity and complications.Sources ?

If it is not posdible then please tell how so many havre been made.Its cant be true. CNC machine can have 1mkm accuracy on spindel movements. But process of producing burs and cavities which appears in process of milling cant give you less then 20mkm. It is limitation of process not cnc machine.
Research has already more than quantified this as exceeding clinical acceptability.If it is not posdible then please tell how so many havre been made.
Sorry it is not about my product. I dont have such equipment to measure accuracy. Its the thing what Nobel says why we should not mill and produce bars and multiunit frames in milling centers. They give different investigations on this topic with numbers.well, you are entitled to your opinion.
i do want to know how you qualitatively measure your output, compare with design, and calculate your actual geometrical accuracy. do you scan your finished product? how?
nobel has a vested interest in dissuading you from trying to mill bars. i hope you realize that.Sorry it is not about my product. I dont have such equipment to measure accuracy.
