Change the screw access hole orientation, 3Shape

[Car 54]

Believe it or not, I've never done a screw retained implant crown, but I am now being asked to do those.
I'm just trying it out on an old abutment on a different old model with an analog in it
So I watched a video, but where am I missing the option where you can change the angle rotation.
I can change up and down, left and right, the width, but can't change the angle.
I need it to be more in line with the long access of the implant hole.

Do I need to base out the access hole with scan wax 1/2 way down so 3Shape doesn't show a blank area and it throws it off?
TIA

Under "Default Orientation" you have different options. I am not sure which one to choose, but if you choose 'View Direction', like you did, you are limited to your original choice. I think you also have to pull the 'hole' through the 'bottom'...
I am sure you will get more precise answers, but this will help you to start. ;-)

Thanks, Contraluz I'm still playing around. I tried pulling through, elongating it through the bottom, but I'm still not getting a rotation option.
I tried insertion direction, but the tube disperses and shows the hole in the crown.
Maybe if I deleted the file and started over and tried insertion direction?

I think you need to go with insertion direction
You can only angle it if your manufacturer dme s allow it.
I think)
Pull it all the way through and don’t inforce min. Thickness

I'll give it a try, Willard. Thanks for the post.

This was a pre-existing abutment that when I created the order form, just selected a crown (not an abutment) so I
don't think it's a dme issue in this case?

I guess here is the answer. I don't do many custom abutments in-house, so my experience is limited. But doing crown designs, with screw holes, you get a couple different options how to angulate.

Even with 'view direction', as shown in the picture above, you get to place your hole angulated. As it says, you place your model in the view direction you would like to have your screw hole go, if that makes sense...

Yes, that make sense, that sounds really optimistic. Set the view, angle model direction of the long access before I hit the play button. I'll give it a try.

Changed my vote to, Winner. That was exactly it, Contraluz and Willard. I needed to have the abutment lined up (like insertion direction) looking from the top down of how I wanted it to be aligned, thus the View Direction, meaning.

I first did one with the abutment at a more extreme angle before I hit the play button, just to see. Then I did the 2nd one with what you suggested, and bingo

Also, I had to pull the rod all the way through, like Willard said, as I ended up in getting a tag inside the crown.

Thank you all for your help, I appreciate it

Now, if I can push my luck...lol. About 1 or 2 years ago, one of the 3Shape techs showed me how to create a bevel on the access hole top, so it isn't a shape edge.
Does anybody know how or where that setting is?

That I don’t know...

No problem, as I figure in the green state I can use a green state tapered cone to put a little bevel in it. If I ever find out from support, I'll post it back in this thread.

Thanks to all your help, here's what I ended up with.

I even anodized the abutment and cemented it with Multilink Abutment cement.

All these were first's for me, in what you all have been doing for years. Little Scotty's growing up

Nice job

Be careful polishing that abutment. Don't polish that bevel. That's what the abutment uses to seat on the implant properly. If you over-polish it any, it could cause some micro-movement and have issues down the road.

 

[KentPWalton]

It looks like the bevel has been over-polished. You may want to get a new abutment.

Thanks for your input, Kent, I appreciate it and will keep that in mind for my future restorations...but this was a throw away abutment and quickly done with a Bicuspid tooth file in a lateral implant position on a throw away model, in which I was just trying to learn how to make the access hole and angle it correctly
