Watch this short instructional video for the contralateral cloning tool in PlanCAD 6.0. Dr. Michael Kelliher shares his time-saving tips for scanning and design on an anterior example.
Hi, it's Mike Kelleher here with a little video I shot here on how to use the contralateral clone feature in PlanCAD version 6.0. This is one of those features we've been asking for a really long time very, very handy to have if you've got that perfect anterior tooth and you're trying to do a crown on the contralateral tooth.
So, in this case, we're going to do tooth number 9, tooth number eight is a perfect tooth and that's a very, very helpful thing to be able to do. Saves you a lot of time in design. So hopefully you'll be able to pick up a few tips on this video and learn how this new feature works.
OK so here's how we're going to set up a case for using the contralateral clone. You set this up just like you would for any other clone case. So you're going to tell it it's a crown, set up the tooth. We're in tooth number 9 we're doing here and just use libraries pre-op otherwise, everything else is the same.
Scanning is a little bit different we're going to do one thing that's a little, will seem a little odd but it does make some sense. When you're going to scan your prep scan it into pre-op because what has to happen here is the software has to have this pre-op model of the tooth you want to copy available to clone. Just like you would if you were, say cloning a tooth for under a partial or something. You need to have that pre-op model. So we're going to scan … our prep into the software as pre-op and then we're going to go over to whatever arch it is, in this case, is going to be upper and we're going to use time saver just copy it over and we're not going to make any changes to this, we're not going to erase and add anything this is exactly we want. We just basically need two copies of this model available to the software. So that you have one to work on that the case is normal and the one just for the software to build a copy over that contralateral clone.
So we're going to go ahead and we're going to trace out our margin here just like we normally would on the tooth. I'm not going to get too, too fancy with this just because this is not a case that I'm actually placing but I used trace most of the time for my margins. Like anytime in the mouth this case like this you probably could get away with using less so but I don't find that to be all that helpful most the time.
So I try to stick with one thing and just do the same every time. That's how workflows tend to get better and faster is if you have things that just are your go-to and you aren't always switching around between different things. So that should be fine …
Then we're also going to need to mark the clone just like we would normally. The key difference here is in version 6 you now have this box. This is contralateral. So this it's a checkbox. So if you're using if you're doing a regular case like … you have the pass for under a partial kind of crown you wouldn't click this but in a case like this, you'd click the contralateral. That's letting the software know that - hey we're going to copy this and we're going to flip it around, mirror image it and put it on top of this.
And you over into the plan tab and you'll see now you've got your [tooth] flipped over. You can even see if there's that little notch there that it's just copied over and that's on the distal edge just like it is on this one and we can kind of move this into place and you would want to do that get that moved into place and get that approximately back to where it should be.
It all looks good. Move over to design now and we're just going to apply the pre-op.
And we'll see that drop in nicely there and those shapes are roughly the same you do have a space between. That happens. Anybody's use clone before knows that tell that that tends to work out.
What want to do now is use smoother and dropper as a way to close the proximal contacts that's just for any anterior design when you're copying and it is clone to wax up or anything we'll be familiar with that so what I'll do here is I take away the model. I go to my dropper tool and just kind of use that in kind of a paintbrush fashion on that proximal contact area. You don't want to use rubber too thin here because you don't want to be pulling at this and creating shapes. You want to just use your dropper smoother in combination until you get everything closed up the way you want it and we still got a little ways to go here.
You could also use some of your incremental change tools if you wanted to as well to get that contact closed up a little bit more quickly but this for me tends to work out pretty well.
And again back to some smoother here to just get rid of some of that excess area, bring that proximal contact up that maybe even a little bit heavy but now you get the idea of what you're what you're looking to do here. But the idea too you do not want to do too much to this because you basically have your shape here you really just want to get it kind of smoothed out and all now. You know if you do see a little height discrepancy you could come back over here incrementally and if anything you know with anteriors I tend to want to have a little more here because it's very easy - you do a lot of anterior work as post mill finishing so you know you see there's a little irregularity here. I wouldn't necessarily try to fix that here. That's so easy when you've got the eMax in the purple stage just to kind of run a little diamond across that and get that smoothed out and make that better.
You can drive yourself bonkers trying to get that absolutely perfect and it will take you no time to get that squared away in the in the post mill finishing phase of things but that gets you pretty darn close. And that really does speed up the process. I don't have an opposing here but you would obviously go through all the other steps of checking your material thickness, checking your occlusal contacts, all that stuff but that's all going to happen in the area that's not aesthetically all that critical. What you really want to make sure is you get this frame of the tooth all looking exactly right and matching up.
So this is a feature that we've been asking for this for quite some time to be able to clone these anterior teeth and now we have it in version 6. So another tool to help make things easy in the anterior with design which is always a bit of a challenge. So hopefully you found this interesting and I know you'll find this feature very, very helpful.
Alright, have a good day.
