I have a case that has come back for a second remake because they are complaining my impak nightguard is too hard. The first one I made with the standard 3:1 ratio, the remake I made with the softer 2:1 ratio. They keep insisting they want thermoplastic and not soft, but Im not convinced they will be happy with any further impak remakes. At my old lab we had the ivocap injection system so I'd make elastomer in this case, but my new lab we doesn't have the system. What does everyone else use for soft nightguards? Should I speak with my boss about getting injection for elastomer or sending it out to another lab?

Greetings Earthling! Welcome!

I don't have the answers, but someone does and they'll be around soon as the second pot of coffee hits.

What we do for Thermal/hard nightguards is using a thermal acrylic on the inside of the nightguard, and then doing the surface and lingual side of the anteriors with hard acrylic. You get the in-between of super soft thermal and hard acrylic surface for longevity.

If even that is still too hard, we do sometimes use thick vacuum form materials for splints, these are very soft but do not stand up to much punishment if they are heavy grinders, you can augment them with hard acrylic surfaces but that can be a bit more challenging.

We do the hard/soft dual laminate vacuum formed and pts love them. Soft around teeth but hard outside.

All of the above suggestions or you can line a hard nightguard with Dentsply's clear permasoft which you can control how soft to make it.

Clearsplint is nice stuff, but it is exceptionally technique sensitive. The best version I've heard to process it flawlessly every time is a dedicated pot and a sous vide cooker on the pot. Clearsplint has a 5degF window they want it in. 2.5dF either way from IFU temp. 4 degrees off and it's cloudy or very smelly or both at the best result.

edit: cant spell and here's a link if you don't know what I'm talking about.
