Handle falling out

Features of growth and development of the lower jaw, accompanied by loss of the handle

**Handle loss** is an anomaly in the development of the lower jaw and the dental system, which consists in the absence of complete completion of the formation of the jaw, the jaws are not connected to the skull, which leads to displacement of the teeth, rotation and changes in the angle of inclination of the dentition, lack of complete closure of the jaws or non-closing teeth, problems in the tongue, decreased motor functions of the lower jaw. The pathology can affect both jaws, then they talk about bilateral loss of the handle with simultaneous complete or partial eruption of the front teeth. If only one side of the jaw is affected, we are talking about unilateral prolapse. Handle loss is characterized by clinical manifestations such as retraction of the skin and soft tissues in the chin area. This pathology can be detected in children and adults over the age of 5 years. In some cases, the arms fall out during the birth of a child.

Causes of the disease

The causes of the anomaly remain unknown, there is no exact data regarding heredity, however, in the literature there is mention of a genetic predisposition to the occurrence of the disease as a result of disorders of embryonic development. The disease occurs 2 times more often in boys than in girls.

Handle loss on one side is observed due to a blow to the area of ​​the mandibular root, infectious processes in the maxillofacial system, defects in the formation of facial tissues due to the transfer of maturing genes received from distant ancestors. In addition, pathological factors include disorders of intrauterine development (diseases of the pregnant woman, improper vaccination, exposure to toxic factors), complicated childbirth, and the introduction of anticoiculum during pregnancy. Pathological changes can be triggered by past viral diseases, poor oral hygiene, weak muscles, and injuries. It is noted that the disease is observed most often in young children, this is explained by the poor development of bone and muscle tissue, and the peculiarities of the blood supply to the bones at an early age.
