3D surgical planning

[streo]

How many here are getting their orthognathic surgery planned in three dimensions?

[Krista]

Which surgeons do that?

Which surgeons do that?

I think you have to ask.  Both orthodontists and surgeons can use 3D planning for anything relating to the skull.  Supposedly there is a big difference between using only 2D cephalometric tracing and using both 2D/3D planning.

Three-dimensional computerized tomography (3DCT) is increasingly being used for surgical evaluation and planning in academic settings. Preoperative planning using 3DCT offers multiple potential advantages, including the ability to easily consider multiple different surgical approaches to a problem and the ability to characterize degree and direction of skeletal movement at any point over the osteotomized segment (as opposed to only the occlusal level). With advancing technology, such 3D visualization of the patient's anatomic deformity is likely to replace today's conventional 2D cephalometric analysis.

Of course there is this article by Arnett & colleagues that was posted somewhere else on this forum talking about 3D planning.  Arnett has done quite a bit to push technology in this direction, so it's safe to say that if Arnett/Gunson are involved, then you probably are getting this type of technology applied to your orthognathic plan:

Might be a good question for hara.v. She had a 3D model done through the NHS, I believe.

Yeah, it would be safe to assume she's in 3D.  Goes to show NHS isn't as bad as people think!

[neferkitti]

I believe the technology is called stereo lithography. Correct me if I'm wrong. I only know this because we were looking into it for our business (unrelated to dentistry). It's definitely not cheap, so the average practice is unlikely to offer this. However, I suppose they could contract out.

Well, they have the capital that small private practices often do not. But, yeah, it's awesome for her since her case is complicated.

For those planning surgery with arnett or Gunson out there did you get 3D imagaging projections of yourself??

[Marisama]

No, just 2D at the initial consult.  They use 3D technology for surgical planning though.  I've posted a video on my blog called VSP Orthognathics showing this.

yes. both gunson and arnett do it, but it does not show the soft tissue.

What do you mean it doesn't show the soft tissue?
