What is Osteonecrosis of Jaw (ONJ)?

August 18, 2014

Osteonecrosis of the jaw (ONJ) occurs when the jaw bone is exposed and begins to starve from a lack of blood. The bone is not heal and painful.  ONJ is associated with cancer treatments (including radiation), infection, steroid use, or potent antiresorptive therapies that help prevent the loss of bone mass. Examples of potent antiresorptive therapies include bisphosphonates such as alendronate (Fosamax); risedronate (Actonel and Atelvia); ibandronate (Boniva); and denosumab (Prolia). 

Below is a photo from a case presentation by JCDA Oasis on Aug 6,2014. This 64-year-old patient  Received intravenous zoledronic acid (ZA) 4 mg monthly for approximately two years

before the implant treatment.

My diagnosis is the same with most of the Doctors : Bisphosphonate induced ONJ.

The passible treatment is shock wave + PRF.
