👉 Phanerosis is a medical condition in which the bone of the lower jaw, also known as the mandible, grows faster than normal. This can lead to a protrusion or an abnormal appearance of the upper jaw, called a "physis". The bone growth may also cause other symptoms such as pain and difficulty chewing. Phanerosis is often caused by a genetic disorder, but it can also be due to trauma or conditions like osteoporosis. Treatment depends on the specific cause and severity
