WTH Screw retain prob

[RileyS]

Please help!! I've got a 6 unit screw retained case. Using NT trading Ti Base. implants are Implant direct interactive. Called supplier of ti base to make sure I order right parts. Bought "F810" which is Nobel active 4.3/5.0 RP and "F800" which is Nobel Active 3.5 NP.
So I scan case with NT F scan bodies, design and mill out of wax just to check. They are all twisted!!??!! I rescanned just to double check, remilled 2 units and still twisted !! What the heck is going on??
See pics.
I marked a line on the model by each (except one or two) analog showing the direction where the square shape of scan body faced. You can compare that to the screen shot of scan bodies.

Cut the tab off the base and line them up

Wrong orientation scan marker to replace geometry !!! mistake in your library or they changed orientation ( FDA ??!!) or home brewed ??

?

add some notches and sandblast

I would send the library to NT to check thats a big mistake.!! And by the way take care of your scan markers handle them like a new girl they are within 3 my replace accuracy.

tab only helps with orientation, not retention
you may have marked the sites wrong.. get the dme. straight from nt site?

sorry riley, couldnt resist. Make sure you have the updated library from NT. They changed they library awhile ago. Show which one you have installed.

How do I find that info?

I have seen this happen when you set up the order and scan then realize that you picked the wrong library or implant diameter and then used the "Switch implant" inside the design program. I think its a glitch associated with scan locator to design library. Would be great if ALL scan locators were keyed to a single coordinate.

If you are milling your own stuff in house get the NT DME and not Argens. Not saying there is anything wrong with theirs just eliminating a variable.

yes! hence my original post about the 3Shape Scan Body. My hope is that ALL the DME's will align to the same coordinates (specifically 3 Shape coords)

Well where did you get your scan markers and library? Lets start there. What version is the .dme?

edit: now I see what John means, this is the argen library. Something tells me they probably have their 'own' library, meaning that it is different from the original NT trading. Download the one from the NT site and try it.

are screw retained crows in that library call Hybrid? In our library NT tradings are Tib (ti-base)

So Argen called me back and it's because I started the case as a hybrid, zr with Ti base, then realised my mistake when designing and changed it to screw retained. That apparently is a big no-no as 3shape doesn't change it...er something

well like I said...

This bleeping case just ate a bajillion cad points.
