Medical status of the patient
Conditions like osteoporosis, history of radiotherapy, use of bisphosphonates which can affect the success of the treatment should be considered before planning the treatment. Bone pathologic conditions like Paget's disease, fibrous dysplasia which lead to altered bone architecture are definitive contraindications for dental implant therapy.
Uncontrolled diabetes and other pathologies like bleeding disorders have to be carefully weighed before starting the treatment process in order to ensure predictable dental implant treatment. Therefore, the importance of a thorough medical evaluation and laboratory investigations to rule out any such pathology cannot be overemphasized
