Briefly: 1. they are tissue supported, so they can exert unexpected pressure on the tissue underneath; 2. they do not develop an emergence profile, which can compromise the final result; 3. pick acrylic can trick the patient into thinking they have gingiva that they don?t actually have; and 4. patients hate them because they?re removable and clumsy.
So I prefer to use alternatives.
But sometimes a flipper seems like our only choice. The adjacent teeth are virgin, so we don?t want to chop them down just to use a temporary fixed partial denture (aka ?acrylic bridge?). And a resin-bonded bridge (aka ?Maryland bridge?) can be a hassle because it?d hard to remove and replace for impressions, try-in, etc.
But there is another option in these cases. Snap-On Smile (DenMat) is a lab-processed resin material that is custom made for patients. It simply slides over the adjacent teeth and holds in place by friction: no cement needed here.
