Has anyone tried using the thermoformed acrylic to make flexible partials? Thoughts?
Can you put a link to the material please?Has anyone tried using the thermoformed acrylic to make flexible partials? Thoughts?
Good point. You can see it on YouTube by searching 4C Partial Denture..it's sold by Posca Dental Supply .Sorry I don't have a Web link.Can you put a link to the material please?
It's an interesting idea, but the forming temp would have to be high enough to deal with coffee and tea. Glidewell has a non-nylon material they are calling Reflex that is chairside and pt reformable in hot water. I can't see this being a good thing, but I don't know enough yet either.
Okie dokie.Good point. You can see it on YouTube by searching 4C Partial Denture..it's sold by Posca Dental Supply .Sorry I don't have a Web link.
Had our spring conference this weekend and the reps were there for the 4C flexible PDs ....
Interesting material and I think it may have some potential.
It is an acrylic material and is repairable as well as relineable.
The teeth are set with acrylic and chemically bonded since the acrylic actually bonds to the 4C material.
Anyway the rep gave me some of the materials to play around with and test.
I'll let you know what I come up with and how it turns out..
At this point I don't provide flexible PD's , but if this material works out I will start offering them to my patients.
Here's a vid on making a PD with the 4C acrylic. This appears to be about all that is currently available info wise.
Anyone that has used clear surgical tray material designed for ANY vac-u-form machine knows the material bubbles if not managed well.
Its always been the same, and truthfully I am curious to see what is different about this material over traditional materials.
Thank's the the analysis! Have you tried to get pmma to delaminate or break free from the disc? Really also wondering, if you don;t mind, if you could discern craze lines at material change joints.Well I was messing around with one of the samples and The more I worked with it the more similar it was to the heavy (.080) surgical stint material.
This from the Henry Schein thermo forming material important notes.....
They state it is hygroscopic and should be stored in in the bag with the dry gell provided.
It also states to heat in an oven at 140 deg. for about an hour then let the material drop to room temp.
This is all very similar to the 4C puck.
The 4C puck is an injected blank which is obvious when you look at it.
It comes in clear or pink.... can you say color added?
Shein's instructions also state that if the stint material is used as a removable prostheses device that it should be cleaned regularly
So I guess you all can come to your own conclusions regarding the 4C material.
I think it certainly has potential and the fact that acrylic bonds with it, fabricating a flexible PD is certainly within the realm of reality for removable appliances.
So with all that you could probably just use the clear .080 Surgical stint material for some flexible PDs.
