Clasp partial to fit a crown

[Tayebdental]

I am interested to know your techniques on fabricating a crown to fit a clasp partial, some docs implement blue mouse registrations of clasps in relation to prepped tooth for that, but it’s not always accurate ,
I do the replication of clasps by placing the blue mouse registration over the prepped die/model and fabricate a gc risin clasps where I spray scan later as an adjacent to design the zir crown In Exocad.
Thanks in advance

Why not ask for a study model that includes the original tooth that is being crowned?
Scan it (edit : as the preprep) and copy the shape around the clasp in exocad.
No need for the pt to give up their partial and you are not rushed

[and copy the shape around the clasp in exocad.] you mean inside the clasp? could you elaborate further:
since I don't have the partial obviously or difficult to replicate clasps in die stone from imp. [ scan as a pre-up model?] Thanks

I would assume that ,in exocad ,you can scan a study model or diagnostic wax up and designate that as your prepreparation.
The software copies that shape and allows you to morph your design to the preprep shape with any morphological improvements required.
The preprep takes the shape under the partial.

I miss username.
He spoke fluent exocad

You're doing good, Creeper.
Thanks for starting our October in your usual fashion, it wouldn't be the same without that, without you

Keep in mind that the dr has a " template" of the original tooth that is used to make the temporary crown.
This temp has to fit under the partial as well.

Good info, I am not that expert in preciso Exocad, but I’ll try to check further, I miss username too we have the same system that we used to discuss

We could ask 2thm8kr but he doesn't do work for the coors light crowd anymore.

Where is 2thm8r, i miss him, I think he abandoned us

 

[Tayebdental]

I found this video based on blue mouse clasp registration.

I am just kidding 2th you didn’t abandoned us, but that was long long time ago, I have been doing that , but I was wondering if there are different ways to follow

Not sure if this has been mentioned but I ask my Dr.'s doing these type of cases to take a PVS imp of the tooth to be prepped before prepping. Then I morph to that pre-op in Exocad and never had an issue ever. That of course depends on the tooth in question is not broken down too much. Sometimes I just polish these crowns to not cause fitting issues by glazing. ( select 1 shade lighter if polishing only)

That is how we do it with a impression but it's soooo much easier if the Doc has a scanner and sends you the files instead. Digital workflow is far superior when it comes to crowns under partial versus traditional impression.

i do get Trios scans, so what’s needed from Doc. is a separate partial scan or a scan of partial over preped tooth? Thanks

Could you show your steps on how to do that in Exocad? Thanks

It was mentioned in the 2nd post but that's ok ,you xocysts are a bit slow. Must be all that purple haze.

Good morning rkm, but that was in 3shapesh I think don’t let 2th hear you

A few ways to do it digitally, but what we have found the best way is have the Doc make two extra scans...have them scan the partial by itself and scan the partial in place around the prep (after it's been prepped) while the partial is fully seated. They won't be able to capture everything in the partial prep scan and that is where you have just the partial scan. Then let all that snap align together in exocad. I hope other folks read this and would love to hear there workflow as well.
