# Introduction
[0] I'm gonna get into how I like to nest All On X prosthetics. I'm gonna do this in Raywear Cloud, but it's applicable to any slicer. So I'm gonna go ahead and find an All On X prosthetic on my computer. Here's an All n x upper and a lower. So let's put those two right into the software. I'm gonna actually call it a hybrid denture.
# Preparing the Prosthetics
[19] And tough two is gray arch kit, and let's go ahead and hit prepare and see what this software does. I'm gonna tell you what it should do. It should rotate the prosthetics so that the occlusal surfaces are down towards the build plate, sisal edge is down. Tube channels are as perpendicular to the build plate as possible. Now, sometimes, like, when you got pterygoids and you got, like, high leaning channels, you can't make all of them perpendicular to the build plate.
[45] So you have to split the difference. But here, we have two different styles of all on x prosthetics. We have a direct MUA here, and we have a true abutment all on t plus there with a segmented bar. Let's go ahead and just first look at the fundamental principles of nesting these. I'm gonna go ahead and turn off autopilot, go to supports, and click on a prosthesis and go to add or remove individual, and let's look.
# Nesting Principles
[70] So, again, Raywear is sometimes notorious. It's kinda like a signature where it doesn't like to nest the mesial surface of a central. So don't forget to add it's the same rules for everything. Go ahead and add a support to that mesial surface. I like to have three sup as a minimum, but four on a central is kinda my go to. Notice it only has, like, one on the incisal edge of that lateral.
[94] So your team needs to know three as a minimum on the cusp tips from canine back. And then in the posterior area, at least one support on each cusp tip and marginal ridge. So cusp tip, cusp tip, marginal ridge. We're missing a marginal ridge here. That's looking pretty good. Missing the distal marginal ridge there, missing the distal marginal ridge there, and there. That's beautiful.
# Adding Extra Supports
[117] And then what I like to do is add a few extra supports right around the tube so that we don't get distortion around the tube, maybe like that. Let's go ahead and click on this one and look. On mandibulars, I still like to try to squeeze in three support tips if possible. And you know you can't if the supports are overlapping.
[145] Marginal ridge, cusp tips. Marginal ridge and cusp tips. That's looking pretty good. We're a little bit anemic with supports here. So that's looking pretty good. So one thing I'm gonna say is around these screw channels, I'm gonna add a ring of supports, not in the actual screw channel, but just around it.
# Final Adjustments
[169] Why do I do that? Well, it's really simple. I want that surface to be supported properly so I get no distortions of my screw channel. So make sure you're not going down inside the screw channel. That's beautiful. I'm gonna hit confirm changes there. This is gonna be a super accurate print.
# Conclusion
[186] What you wanna avoid for all and x prosthetics is large angles, deviations because it's really more your screw channels need to be perpendicular to the build plate as much as possible. So that is how I set up all and x prosthetics and it's really easy to do, and software does a good job at getting you 90% there.
