[Alveolar distraction osteogenesis: possible complications and methods of their treatment]

The aim of the study. Analysis of emerging complications during the method of alveolar distraction osteogenesis in patients with jaw defects. A retrospective analysis of foreign and domestic literature was carried out. A systematic literary search was carried out in the electronic bibliographic databases Web of Science (for foreign articles) and Elibrary and Dissercat (for domestic).

In the period from 2005 to 2019 in the clinic of the Department of Maxillofacial and Plastic Surgery of the Moscow State Medical University. Evdokimov conducted an examination and comprehensive treatment of 490 patients with primary and secondary adentia of the upper and lower jaws, accompanied by a significant deficiency of bone tissue of the alveolar ridge vertically. A comprehensive dental rehabilitation of patients with jaw defects by the method of distraction osteogenesis was carried out.

The most common complications are: exposure of the fixation modules of the distraction apparatus - 24% of cases, failure of bone regenerate - 13%, inflammatory phenomena - 13%, displacement of the distraction vector - 43%, paresthesia - 7%.

Based on our analysis of the identified complications during the distraction osteogenesis method, it was found that these complications are not critical in the treatment of patients with jaw bone deficiency and do not jeopardize the success of rehabilitation. With diagnosis and timely approach to treatment, complications are avoidable.
