Who are the patients that can have implant? Really anybody. Ideally you don't want to place implants on children that are still developing where they're still teething from their first set to their adult sets. So ideally you don't want to work on an early teenager but a later teenager where their development, their facial development, teeth development's all set, then you can place implant on those patients and all the way up to patients that are adults, seniors, basically it's unlimited. As long as they're healthy. If you're healthy. Healthy meaning that you're not on high dosage of medication. Your kidney. your lung, your liver are all adequate then it's not a problem. But if some people have high blood pressure or a diabetic it's not a problem if you can control it medically with your physician then implants shouldn't be a problem.
