What is the rear jaw?

is a large U -shaped bone that forms the lower jaw. It is the largest and strongest bone on the face and contains all the lower teeth. The rear jaw is the back of the jaw. In the primary teeth it consists of only two sets of stools and ramus; In the secondary teeth it consists of two sets of premolars, three sets of stools and Ramus. The Condylar process at the top of the ramus is articulated with a temporary bone in the skull and creates a joint joint of the jaw that allows you to open and close the mouth. These teeth also often have wide and sometimes deep grooves on the surface. For this reason, the sealants are often placed on premolars and stools in the back jaw. The seals are clean, protective layers that cover the grooves so that food particles cannot get stuck in and cause disintegration. This preventive measure is common, painless and is usually placed only on adult teeth.

although the jaw still passes into youngOtost, most of them still do not have enough space for the third set of stools. The extraction of third stools is a common surgery for the rear jaw. The rear jaw is also a common place for reconstruction dental work. The rear teeth, if not sealed, are more susceptible to cavities. If the tooth can be stored, it can be reconstructed by a porcelain crown; If it must be pulled out, it can be replaced by a bridge or dental implant.

The rear jaw may also suffer from fractures or dislocation. Broken jaw usually results from trauma and are associated with bleeding from the mouth, pain, difficulty opening of the mouth, numbness and swelling. Depending on the severity, the jaw fracture may be treated simply by a bandage and a diet with soft food. In Very serious cases, the jaw must be involved for six to eight weeks and may need surgery.

The jaw dislocation occurs when the Condylar process appears on the spot and is no longer articulated with a temporary bone. Symptoms of dislocation include pain, difficulty speakingM, protruding jaw, feeling that teeth do not fit properly and pain in front of the ear that is getting worse. Dislocated jaws can be returned to the dentist's site using the thumbs. It will then be stabilized and administered by painkillers. In very serious cases, surgery may be required, especially if dislocation occurs frequently and is not related to the trauma of the face.
