Dentist Antioch Type of Ankylosis?

Antioch General Dentist discuss Ankylosis

Ankylosis is a condition where a joint becomes immobile or fused due to a disease or injury. In this situation, the bones of a joint are abnormally stuck to each other. Partial or complete rigidity is experienced by people who have this condition.


The two common types of ankylosis are true ankylosis and false ankylosis.


True Ankylosis

True ankylosis is the fusing of bones of a joint due to the loss of the articular cartilage. In this situation, total immobility is experienced. It is also known as bony or intra-articular ankylosis. Joints in this condition have lost their normal bony architecture.


True ankylosis is dangerous since it can lead to a number of physical and psychological disorders. Among the disorders caused by true ankylosis are:


·         Issues with jaw movements

·         Issues with chin and mandible development


The disease can completely immobilize the mandible, which makes it difficult to speak or to chew. It can also cause the growth of the mandible to be delayed. The condition can lead to the “bird face” appearance or micrognathia.


When only one side is affected by ankylosis, it can result to a deformity since the other side will continue to grow normally. Due to this, it can result to facial asymmetry.


False Ankylosis

False ankylosis is a condition where the presence of fibrous tissue causes reduced mobility in the joints. The formation of fibrous tissue affects the joint itself. It also has an effect on the ligaments and tendons used for leverage as used in normal movements. The condition is also known as fibrous ankylosis or extra-articular ankylosis.


False ankylosis may be caused by the following:


·         The scarring due to irradiation, infection or surgery

·         Depressed fracture on the zygomatic arch

·         An enlargement of the coronoid process


Ankylosis causes partial or complete rigidity on the joints. It may result from an inflammation of the muscular structures outside the joints. The condition is also known as temporomandibular Joint Ankylosis, which is normally a chronic and painless condition.
