Hybrid dentures are created to replace a whole row of teeth via an implant. They fuse to your jaw which means they don’t move around. They are designed to also replace missing gum tissue.
Sometimes, a titanium or gold bar is put in to give it additional support. It’s surgery which means they can only be removed by your dentist or an oral surgeon. You won’t have to remove them to clean them or perform maintenance which is good, because you won’t be able to.
