- In most cases contraindications are not absolute and are subject to the individual patient situation and risk assessment.
- Some serious medical risk factors remain. However always consider patient motivation and compliance as well.
- In case of doubt consider non-implant based treatments.
Relevant risk factors for implant treatment:
- Children and adolescents (during ongoing bone/skeletal development), unless in selected anodontia patients. However, implant placement for orthodontic treatment purposes is indicated.
- Uncontrolled metabolic diseases such as Diabetes Mellitus Type 2
- Uncontrolled HIV or tuberculosis infection
- Blood disorders (such as Advanced chronic Lymphocytic Leukemia, chronic myelodysplasia)
- Within 1 year of a heart infarction or cerebro-vascular insult
- Currently administered chemotherapy and/or radiotherapy
- Significant malfunction of a patient's immune system such as immune-suppression after transplantation
- Systemic bone diseases (for example Paget's disease ...)
- Psychiatric conditions such as dysmorphophobia or ones affecting a patient's ability to reason and make appropriate treatment decisions
- Significant abuse of recreational drugs and/or alcohol which interfere with proper social behavior
- Non compliance of patient
- Untreated oral diseases (such as jaw osteonecrosis)
- Therapy resistant periodontitis

Single implants and their restoration
An osseointegrated implant with its restored crown has become routinely recommended for replacing a single tooth. In fact, placement of an implant and crown is widely regarded as the preferred treatment modality rather than a fixed partial denture or a removable partial denture. This treatment planning choice is due, in part, to the high survival rate of single implants and their associated crowns and patient preference. When faced with the choice to involve two otherwise healthy teeth adjacent to an edentulous area or fabricate removable prosthesis, patients are more likely to select an implant supported single crown.
