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?
