Soft reline on printed dentures

[JonnyLathe]

Hey all, I run a lab in house at a clinic.

Currently we print our temporary dentures and our patients go with multiple soft liners while they're healing and getting ready to get into their permanent set.

A pain point has been soft reline not adhering well to printed bases, it just doesn't want to stay in very well despite sandblasting the inside. I was using dentca denture base but now I'm using detax. Do any of you have any extra tips or perhaps a more appropriate material than coe-soft?

Need to print something that will allow traditional adhesion methods. Pretty sure printing the lucitone 199 would solve your adhesion problem. The only issue is I know Carbon allows printing of the lucitone 199 material but not sure if any other printers have the ini file to print that or if it's exclusive to Carbon printers.

I can print Lucitone with my Asiga but I don't have the Dentsply cure box unfortunately. I was thinking of trying GC's soft reline material because it has a resin primer unlike coe-soft.

Nothing will stick to printed denture . Dentsply say that you can bond standard reline using a certain type that they have that is a hard reline. Good luck with soft reline.
Your only and easy solution is to drill mechanical retention holes and ditch the peripherals with a number 8 burr.

I would do the mechanical retention, only I would ditch it out enough to place some fresh hard acrylic then pack the soft acrylic over that and process. I Don't make printed dentures so not sure if they can take the heat, if not then same thing with self cure.

Sounds good, looks like I'll try to go with more mechanical retention. I'm just surprised that coe-soft doesn't stick as well to them as acrylic dentures. I wasn't aware coe-soft offered a chemical bond to acrylic either.

Either way you will have an unsightly line where the acrylic wont stick, the only option to hide it is glaze at that point, which will turn brown in the future...

I'm not too worried about that, we usually replace the softliner monthly until the patient is all healed and ready to go to finals. I just want to find something that's easier for our chairside person to work with.

thats an interesting problem. my first thought is mechanical retention as well. like what fastfngr said.
i just ordered some kooliner from GC still waiting to use it.... its a hard liner but it may retain in the denture better.

have you ever worked with lynal? i love it as a soft liner

Is that the chairside hard reline stuff? I do use that for hard relines and love it. Kind of expensive and time consuming to be replacing once a month while patients are healing though.

try some composite bonding agents. they seem to 'help' make things stick better to those nasty printed dentures

Yeah, I just used it for the first time this week for an upper denture. It seemed to work great!. Although I thought it was supposed to be a hard reline ( definitive) it claimed to be a temporary on the instructions.

It is not as hard as a lab reline and the purpose is to be able to peel it off and change it till final healing and a good final lab reline is done. It takes between 3 and 10min to do it and it should be included in the patient’s treatment plan.

This is how we do it, change them out about every six weeks while the patient is healing. Then we give them the option for a permanent lab reline or a final denture with nicer teeth and ivobase processed.

I would recommend roughening the intaglio surface. Hope this helps!

We always roughen and sand blast intaglio. We started using voco ufi gel and it's working great!

I didn't read this full thread, but I have tried many - mostly GC because I like their materials - unfortunately, it doesn't bond (COE Soft, Tissue Conditioner). I have found that Viscogel bonds well.

The prep agent from GC appears to do nothing, even after removing biofilm from intaglio surfaces (roughing, sand blasting, etc).

GC did change their TC formula sometime recently - I only have the old formula, however.

I stumbled across this thread trying to find out if Kooliner bonds before I buy some to test.

I seem to have a similar process to OP in the management of transitioning patients.

Hope this reply is of some use, as I made this account to reply to this post and share my experiences so far.
