Osteoporosis, is a progressive disease characterized by low bone density and deterioration of bone mass which can lead to an increased risk of fracture. Osteoporosis develops when the body loses bone or makes less bone or a combination of both. There are numerous medications targeted at slowing the progression of osteoporosis, thus reducing the risk of bone fractures.

The most common oral bisphosphonates are Alendronate and Risedronate, also known as Fosamax™and Actonel™ respectively. These medications are usually prescribed as once a week oral tablets. Denosumab, also known as Prolia™ is usually given as a subcutaneous injection once every 6 months. Despite different mechanisms of action, both drug categories inhibit osteoclast cell function. These cells are needed in the normal break down of bone. By reducing the number of active osteoclasts, more of the existing bone is allowed to stay.
While these anti-resorptive medications are very beneficial in managing osteoporosis, they can sometimes be associated with major complications in the jaw bone after having invasive dental procedures. A condition called Medication Related Osteonecrosis of the Jaw (MRONJ), may develop in some patients taking any one of these medications after having any invasive dental procedure ranging from a tooth extraction to implant surgery. Unfortunately, in some patients this complication can develop spontaneously in the absence of any previous dental surgery. The literature shows that the risk of developing this complication remains small. However, you must inform your dentist that you are taking these medications if you haven't done so. For more information about MRONJ, please read the position paper of the American Association of Oral & Maxillofacial Surgeons, posted on our website.
