"I wore Michigan splints for several years. Then the NTI-tss, which broke in two after about a year. Today I wear an FOS upper jaw splint. I find it liberating that I can slide my jaw freely left and right without the splint clinging to my teeth. I find the fact that the splint holds four teeth perfect. In summary, I can say that the FOS splint helps me best and is the most comfortable to wear."
