at the base of mandible. However, these implants are rarely used (Gougaloff, 1-9).Patient selection is an important ingredient to the success of the procedure. A complete and thorough medical history must be completed and evaluated before the procedure is considered. Systemic conditions that may affect the success of the implants are numerous. Diseases of Cardiovascular system are given careful consideration and prophylactic use of antibiotics and consultation with the patient’s physician is recommended. Gastrointestinal System disorders include symptoms such as vomiting, hypersecretions, xerostomia, and hyperacidity, which can contribute to changes in saliva PH that may alter the healing of the mucous membranes. Various ulcers of the GI tract can reflect the amount of stress in a patient’s life. This same stress can manifest into bruxism, which can lead to implant failure. Disorders of blood such as hemophilia are not suggested for dental implant treatment. Patients taking anticoagulants are also consider poor implant candidates. Other medical conditions such as immunological suppressed diseases such as HIV or diabetes must be taken into consideration, because they affect the healing ability of oral mucosa (Babbush, 1-32). Other conditions such as osteoporosis, diabetes, and long term medications such as corticosteroids, immunosuppressants, nosterodial anti-inflammatory drugs and antibiotics can also effect the success rate. Also poor general health and collagen related connective tissue disorders such as sclerodoma, Sjogrens Syndrome, Rheumatoid Arthritis are considered to be contraindicated for implant treatment. Smoking is believed to also cause implant failure. Dental radiographs are also an important factor to determine the bone contour and quantity in selecting a candidate. Most patients who are healthy and undergo normal dental treatment and maintain good oral hygiene can have dental implants. Individual ...
