MRONJ case

 75-year-old female patient visited the hospital for tooth extraction due to discomfort #16 and #17 areas. I have a history of taking medication for osteoporosis for about 7 years. The possibility of MRONJ occurring was explained and the tooth was extracted.

MRONJ could not be diagnosed on the radiography, but when the tooth was extracted, the tooth came out with too much force and there was not much bleeding at the extraction site, so it was assumed that MRONJ was present and the flap was opened to confirm.

When the upper alveolar bone is removed, an internally infected accessory bone is observed. All of the swelling has been removed.

This is the healing pattern after 1 month.

It is known that MRONJ occurs due to tooth extraction, but in reality, it is thought that the remaining appendicular bone may be causing the problem by simply extracting the tooth when MRONJ has already occurred.
