Placing of oral implants in patients using bisphosphonates
Dentists are with increasing frequency confronted with patients who are being treated with bisphosphonates for certain bone diseases, hypercalcaemia, and bone metastases of solid malignancies. A side effect of the use of bisphosphonates is osteonecrosis of the jaw. Bisphosphonate-induced osteonecrosis of the jaw occurs mainly after treatment with intravenous bisphosphonates and to a much lesser extent after oral administration of bisphosphonates. The question remains whether oral implants can be safely placed in patients using bisphosphonates. A survey of the literature shows that the risk of osteonecrosis of the jaw and loss of oral implants is not increased when the implants are placed within 3 years after starting treatment with oral bisphosphonates. After this period there is the possibility of a slightly increased risk of complications. The possibility of complications is higher in patients receiving the intravenous bisphosphonates, and, therefore, elective surgical treatments is not advocated.
