Milling abutments/bars

[shane williams]

Hey is anyone milling there own abutments or bars? Looking at getting an imes icore 550i. Good/bad? The picture of the machine shows them milling abutments on a disk of titanium so it actually mills the interface. Is this possible or is it a patent infringement? I was told that you can buy blanks that already have the interface. Where do you buy those at? Does any of this make sense or was I told a bunch of malarky!

Haas OM2-a with exocad and SUM3d.

This is best solution if you live in the USA. Make anything you want.

Glidewell used this (Haas OM2-a) . You can come see mine when it arrives.

This is wondeful Industrial mill, with Reinshaw touch probe and tool-setter, 5axis wet-mill with FAST feed-rates and 5HP Spindle for shreading some Ti. (The way I am making mine)

Your tooling costs will be reduced by allowing freedom of options and sources, and tool clamping system is from Switzerland and increases tool life by keeping T.I.R. to a minimum. (Total Indicated Run-out of tool.....or wobble)


You can get trained on the Haas Contoller all over the US.


I hope to be selling this as a turn-key package soon.

Using 3shape and sum3D I've successfully milled denture bars out of wax for casting with no problems.

Haas will not help you do this on your own. They just sell Generic mills.

You will need all sorts of companys to help you get it all together. Rego-Fix or Technixs tool holders, some sort of fixture system to hold whatever material you choose, Software CAM-guru to set-up Reinshaw W.I.P.S. and CAM guy to workout the Post and strategys, etc....Calibrating your 4th and 5th axis Rotarys...

In the end....you eliminate all "Re-sellers" of Dental things, and you enter the real world of Industrial milling.

The costs saving are worth the extra research to do this.

I'd be glad to help, or set you up.

Your tool costs will be much lower, service agreements, ability to resell the mill into any Industry is a plus.

Not a locked "Dental" mill.

So this isn't some buy a mill and start milling your own abutments. Thanks for the info. My boss is getting kinda gun-ho about doing abutments. I keep telling him there's more to it than just buying a mill that does titanium.
So imes is the wrong mill to go with for this? I haven't a clue about milling ti. I think we aren't quit there. So this setup your telling me Scott it will mill the interface too, not just mill a blank with the interface. Are those even available? What's the cost for a setup like that.
I read a post that SUM3D will be at the California CAD/CAM symposium, you still sponsoring that? I plan on attending that event.
Thanks for the advice.

Shane - Search the forums for "Abutment Blanks". Some threads have links to companies that supply blanks. I have seen them used but no personal experience.
I have seen the Haas at Glidewell and I know that Glidewell also used blanks. Not sure if they do now..

I have 550i and we mill custom abutments from ti and zr with ti base. also bars, No problem!

Look at FrenchCADman's posts.

He is using Exocad and a Micron mill I think.

Don't get stuck with a closed system that requires pre-milled interface. Not much profit in that.

iCore is good, just not many service guys and replacement parts in the US. Our exchage rate os USD is not in your favor.

By staying in the states with a Haas....it's a win/win.

Anyone besides B&D selling pre-milled ti blanks for most abutment platforms

The problem is getting the FDA approval for the Interface between the Abutment and the Implant. Thats why you dont see many people doing it yet. 550i is a fantastic machine and you will probably recoup your money quicker than going with the Haas, mainly because all the work its set up to create them today. You will spend more time R&D the Hass to get to a workable machine and then when you have it all set up are your interfaces FDA approved. The price above looks nice but once again X Y Z no A B in that so the Bars are out.

Curently though the way the 450i, 550i and 750i is setup is with interfaces. You can mill out the interfaces on any machine as long as you CAM it correctly, but do you want to have it loaded into somebodys mouth. I think its still a gray area right now.

I know of a lab using a TDS Cutter to do all their bars and abutments.

Pete, you need to add the TR-110 Twin rotarys and 4th and 5th axis wiring. ($35k? total cost)

Then you have to get that set-up...

Then, a tool probing system to off-set the tool lenght for tool changes.

A fixture, and other odds and ends.

Find a CAM to run the mill...make a few small custom programs...

Scott,
I'm not in the market for a mill right now. My landlord buys and sells big cnc machines (ison Tool inc.) and anytime he runs across something with a small work space and high rpms he shoots me a email. It's kinda fun to walk through his warehouse a look at these large multi ton mills.

I talked to that guy in OH with the mill yesterday.

It has new Spindle only a few days old, but 1 1/2 HP. Mill was used for Aluminum.

No wiring inside for 4th/5th axis stuff.

These mills (Haas) really hold their value way more than anything Dental.

This used mill above would only save me $15-$18 from a new one, if that. And it's years old +?
