My first implant (late 20, insert from inside the mouth) has lots of problem, asymmetrical, one wing create a ledge, too long... Overall, I hate it. After talking with the surgeon about the problem, he decided that it's too complicated to work with me and offer a refund if I remove the implant. It's ideal to remove and replace the implant in one procedure, but if I want the refund, how long after removal can I re-implant? It's risky and bad the perform the procedure separately?
