Etiology, Classification, Frequency of Bone Defects and Lower Jaw Deformation (Literature Review)

In  peacetime,  non-firearms  of  the  lower  jaw are usually observed. They arise as a result of resection or disarticulation of the jaw (in connection with a benign or malignant  tumor),  its  elongation  in  the  elimination  of underdevelopment,  after  suffering  osteomyelitis  or  overly extensive  and  uneconomical  sequestrectomy,  after  an accidental trauma, etc. [6,9]. Among the many reasons that lead  to  the  occurrence  of  defects  in  this  localization, oncological pathology takes the first place, with malignant tumors accounting for up to 16% of cases, benign ones - up to 42.9% [10, 11, 12]. Traumatic injuries, gunshot and non-gunshot  wounds  of  the  maxillofacial  region,  leading  to defects of the lower jaw of various lengths, occur in 28.5% of cases [7].
