# Denture Realignment and Delivery Process
## Initial Assessment
[1] This patient presented with an old denture on the maxillary arch, and she was missing some teeth on the mandible. What we decided to do was realign the old denture and just use it as a foundation to make new dentures, where we used some polyvinyl siloxane, light body.
## Scanning and Fabrication
[19] We then scanned that 360 degrees out of the mouth, placed it back in the mouth, and captured the bite. We additionally scanned the upper edentulous arch and the lower edentulous arch in which we use those scans to fabricate new dentures for the patient. And so here we are at delivery day.
## Delivery Day
[41] I have a new 3D printed upper denture and a lower flex partial denture that is printed out of a retainer material, which allows for flexure and memory to where when I let go of the prosthesis, it springs back to the original shape, which also leads to really good retention in the mouth, especially in clasped areas. So let's see how these things look and feel to the patient.
## Denture Delivery Check
[68] So the denture delivery is really just a quick check of the occlusion, the aesthetics. I like to go through phonetics to make sure everything is okay with my fricatives and my closest speaking space, such as my 60 sixes and my s sounds. And then I go into my f sounds with my 50 fives to look at sisal edge length.
## Border and Retention Check
[91] I also look at borders. And what I like to do is stretch the muscles of the mouth like this and pull and see if the denture moves out of the way, especially with the intraoral scan here. Remember, we're not doing border molding. We're doing a mucostatic impression and adding back selective pressure. I also like to check retention of the denture.
[113] I like to grab hold of the denture and see if the patient's head moves with the denture as I move it. These are all good signs that you have really good retention.
## Flex Partial Denture Assessment
[122] And on the lower for the flex partial denture, the things that I like to look for are comfort and to make sure that it's not too hard for the patient to remove, that they're able to do it on their own. And to make sure everything is super comfortable with the occlusion on a partial denture is super important that you're putting the proper forces on the ridge so that you don't cause proper, if you don't put proper forces on the ridge, you might cause some accelerated bone loss. And so that's what's really important, for a flex partial denture.
[149] I also like to look at reciprocation and look at my contralateral side, retention and make sure everything is stable.
