How common is jaw necrosis with bisphosphonates?
In osteoporosis, bisphosphonate associated osteonecrosis of the jaw is rare and the incidence may not be greater than the natural background incidence. Epidemiological studies have indicated an estimated incidence of less than 1 cases per 100 000 person-years of exposure to oral bisphosphonates.
Which bisphosphonate causes osteonecrosis of the jaw?
The incidence of bisphosphonate-related osteonecrosis of the jaw (BRONJ) has been strongly correlated with the aminobisphosphonates pamidronate (Aredia) and zoledronic acid (Zometa) and is even higher in patients who have had recent dental extractions.
Do all bisphosphonates cause osteonecrosis?
Low-dose bisphosphonates given either orally or intravenously in osteoporosis patients have not been causally linked to the development of osteonecrosis of the jaw.
How long does it take for osteonecrosis of the jaw to develop?
Osteonecrosis of the jaw is diagnosed when exposed, necrotic bone is present in the maxilla or mandible for at least 8 weeks.
What are the stages of osteonecrosis of the jaw?
proposed an ONJ classification comprising three stages (31): stage 1 = bone exposure but without signs or symptoms of infection; stage 2 = bone exposure/necrosis with clinical evidence of infection; stage 3 = the above manifestations and also alterations such as pathological fractures, extraoral fistulas or osteolysis …
How long is it safe to take bisphosphonates?
To reduce the risk of these rare complications, your doctor may recommend that you temporarily stop taking bisphosphonates after 3 to 5 years. This is sometimes called a bisphosphonate holiday. People who have severe osteoporosis may need to wait for 10 years before they stop taking these drugs.

How does necrosis of the jaw start?
Osteonecrosis of the jaw (ONJ) is classically considered a disruption of vascular supply or avascular necrosis with exposure of the jaw bones. It can be caused by radiation, high-dose steroid therapy, and medications that disrupt vascular supply or bone turnover in the jaws.
Is there an alternative to bisphosphonates?
In recent years, the drug denosumab (Prolia) has emerged as an alternative to bisphosphonates for the treatment of postmenopausal osteoporosis. Denosumab may be considered a first-line treatment for women with osteoporosis who are at high risk of fracture or in women who can’t take bisphosphonates.
