# Introduction
Let's get into how to nest partial dentures. There's two styles of partial dentures [0]: most commonly printed, monolithic or split file. Monolithic means that the tooth is already attached to the partial denture base in the design software, meaning that you don't have separate teeth. Whereas split file means that you have to print the pink base material and the teeth separately and bond them together, and we treat those just a slight bit differently in the software. So let's first start off with monolithic partial dentures.
## Monolithic Partial Dentures
And I'm gonna go ahead and find a partial denture on my computer that is monolithic. Here it is, monolithic partial denture [29]. I'm gonna go ahead and open that up. And what I'd like to call a monolithic partial denture is not a denture base, not a hybrid, but I actually like to call it denture teeth. I find that it does a really good job with the algorithm. Let's go to arch kit. I would actually clinically, I would print this either out of retainer material or, Onyx Tuff.
Let's see [57]. Let's go to Tuff two point o for this. And let's hit prepare and see what it gives us. Now what it should do is take the incisal edge of the teeth or the occlusal surfaces and put it parallel to the build plate with incisal edges down, occlusal surfaces down, and add an adequate pattern and distribution of supports to properly print this. And it crushed it. Look at this. Guys, this is what I'm saying.
That is actually beautiful [82]. There's only a few things I don't love. And if you look at the nesting guide, you'll understand what those are. One is the clasp tips are unsupported. And if you didn't pick up on this and you just hit print, you have a successful print with distorted clasp tips that might not fit. So let's turn off this sweet autopilot. Let's go to supports, add, remove individual supports.
And all I'm going to do is [103] I'm gonna keep to my rule with four points on the incisal edge of a central, and I'm gonna support the tip of my clasps. And I wanna make sure that the very distal extension has a support point on it right there, and there's a support point on each embrasure space like that. That is a beautiful oh, man. This thing is gonna snap right in. I'm gonna hit confirm. That is how you properly print a monolithic partial denture. It's just like that, guys.
## Split File Partial Dentures
Now let's go ahead and see how we would do a split file partial denture because it's just a smidge different [139]. So I'm gonna go back to, I'm gonna hit new print job and I'm gonna find a split file base here if I have one. Partial base. Partial base. Let's see what that is. Okay. This is a big old, AP bar partial denture on a maxillary arch. Now you might be tempted to call this a denture base, but you would be wrong. It's not gonna set it up properly.
It's just gonna be confused about a lot of different things [176]. I actually like to to again call these denture teeth, and I actually will pick Apex base. And let's hit, prepare. Oh, let's switch to the arch kit. Prepare a print. And, again, arch kit versus standard kit doesn't matter for the purposes of nesting. You basically treat those identically. So, again, I typically print my gingiva for my partial dentures, sockets down. Sockets are the areas that the teeth are supposed to fit into, down towards the build plate.
And I'll talk about this, but this does add a little bit more finishing because you have to make sure that, you get rid of these support spots in a tooth socket [223]. Luckily for us, most printers these days, this is gonna be very easy peel support. They're they're a lot smaller than they look here on screen. So let's just go let's turn off the autopilot, go to supports, and add remove individual supports. Let's take a look at this. Few things. The very tip of the clasps need to be supported. So here and here.
Here [245]. Other than that, this is beautifully supported, guys. I cannot see a single area where I need to add or remove support. So I'm just checking this. What you're looking for is an adequate pattern and distribution, no clustered supports, no jumbled up supports, and no large areas that are red that are missing supports completely. And so this is beautiful. If I was gonna be really nitpicky, it would be just to add another support to the tooth rest seats so that they don't distort and sag, so I have a perfect rest seat.
But that's it [279]. Confirm changes. That was just too easy. I do notice that Rayware is always learning, and it just always just seems seems to get better and better with time. But that's how I like to print all my partial denture bases. It's super accurate to print horizontal like that. So let me go to a new print job, and let's load the tooth in there and see how we would do that. So let me see if I could find a partial denture tooth. Here's partial teeth.
These teeth go along with that same base [306]. So I'm gonna go ahead and and call it denture teeth. Now this particular thing is in a, standard setup where the the STL file is one STL file for multiple teeth. You might find your designer might send you multiple different STL files for different teeth. You have to watch out for that. Doesn't matter either way. You're gonna treat them the same. Clusal surfaces down towards the build plate is a good way to predictably print these. Let's take a look at our rules.
I'm gonna turn off autopilot supports [336], click it, add or move individual. And, again, it did a really, really awesome job. I'm gonna add one to that distal marginal ridge right there. I'm gonna add three to the incisal edge there, and then I'm just gonna go ahead and central. I'm gonna squeeze. I'm gonna probably just add you know, I just can't get away with not doing something. So I'm gonna add one more support to the mesial and sisal and just drag drag that one right there. That's a beautiful setup.
So if you look at the rules of this, four on the central [370], three on all the other teeth incisal edges, and then as we get to the posterior, a dot on the marginal ridge, each cusp tip, and then, one or two in the central grooves as needed. This is gonna be a phenomenally accurate print here. Let's hit confirm. Beautiful. I love that. Okay. So that's how you basically print partial denture teeth in a nutshell and partial denture bases and monolithic partial dentures.
