Implant supported prostheses include over-dentures, crowns and bridges. These are the treatment of choice in modern dentistry. They are very predictable in nature and have a track record of very successful life span serving their purpose. But, there are certain conditions where the dental implants cannot be provided due to the inherent nature of the disease. The implant supported prostheses are contraindicated in the following conditions:
- Immune disorders (leukemia)
- Disorders of coagulation (anticoagulants, liver cirrhosis, thrombocytopenia, tendency to hemorrhage)
- Rheumatoid disease (steroid medication)
- Unstable endocrine disorders
- Chemotherapy (i.e. bisphosphonates) and radiotherapy within the last 5 years
- Patients under 16 years old (incomplete development of bones)
It's not that the implant will fail in these patients, but their physiology, especially bone physiology gets changed; therefore, these patients do not get the full advantage of the implant supported prostheses.
So, it would be wise to provide them the other type of prosthesis, unless they have been treated and have a stable condition.
