[QUOTE="TheLabGuy, post: 280303, member: 126"] Their is a lot of difference between the high performance polymers out there (some a lot more rigid than others). I only really have experience in Pekkton myself, done a few hybrids with this stuff. I used the BDT Technique on these particular hybrids. The Pekkton did have some give/flexibility, which was great (because I thought heck yeah, it'll act like a PDL when being used with implants). After a few under my belt, I realized pretty quick that you have to have the vertical thickness there to use. Without using a metal substructure (which you can use with Pekkton),I feel a lot better about these type of appliances when you have the proper vertical dimension (15 to 16mm) to work with. The zirconia is so technique sensitive, you must have a rock solid protocol in place, good thing about that stuff...is that once you get that down, the high performance polymers will be nothing for you. As for metal, it's my fail safe, if I can't use others, I always sleep well using metal. Personally, I think once these high performance polymers (Pekkton, Pekk, BioHPP, Trilor) become FDA cleared for permanent use for implant abutments then it will take off here in the states.
