Can my health affect my suitability for implant treatment?

Yes it can. Disorders such as severe osteoporosis (a condition which makes the bone thinner and more fragile) or conditions which affect the body's ability to heal, or resist infections (such as uncontrolled diabetes or some immune diseases) are contra-indications to implants. This is because an implant requires healthy bone healing to secure it in place to enable it to act as a foundation for a dental restoration. Any condition which adversely affects this healing ability can lead to implant failure.
