Item. A review of the literature is presented on the current problem of maxillofacial surgery – methods of fixation of bone fragments in fractures of the lower jaw. The purpose of the study is to study publications on methods of fixation of fragments in fractures of the lower jaw in the comparative aspect of their influence on the clinical course. Methodology. The publications of domestic and foreign authors on modern methods of fixation of bone fragments in fractures of the lower jaw were studied, and a comparative analysis of their effectiveness was carried out. Results. Currently, orthopedic and surgical methods of immobilization of bone fragments are used, which are used both in isolation and in various combinations. During surgical treatment with the help of mini-plates, it is possible to perform optimal reposition and stable fixation of fragments, however, the traumatic nature of the operation, leading to bone hypoxia, slows down the processes of reparative osteogenesis and leads to the development of postoperative complications. The use of bone glue-cement makes it possible to achieve reliable fixation of bone fragments, accelerate the formation of a callus. At the same time, there is no need to remove the glue, since it is a biodegradable material. Conclusions 1. None of the currently used methods of fixation of bone fragments in clinical practice for fractures of the mandible, both orthopedic and surgical, as well as in their combination, can fully meet the optimal conditions of reparative osteogenesis. 2. A promising alternative method is the use of bone adhesives that fill the bone voids between fragments, which contributes to their stable fixation and reparative osteogenesis, biodegrading simultaneously with the formation of a callus.

Thing. A review of the literature devoted to the topical problem of maxillofacial surgery and surgical dentistry – methods of treating patients with mandibular fractures was carried out. The aim of the study is to review the materials of publications on the methods of treatment of patients with mandibular fractures. Methodology. The publications of domestic and foreign authors, considering methods of fixation of bone fragments in lower jaw fractures, have been studied. Results. Publications indicate that there are many treatments for mandibular fractures. Research results demonstrate the importance of bone stabilization for bone fusion. A common disadvantage of conservative and surgical methods of treatment is unstable fixation of bone fragments, which is the most common cause of delayed consolidation of a mandibular fracture. The presented studies show that bone osteosynthesis with metal plates is considered the most appropriate method for treating mandibular fractures. Conclusions. Splinting as a method of treating fractures of the lower jaw has a large number of disadvantages. A common disadvantage of methods for splinting the lower jaw is that these structures do not always provide anatomical reduction and stability for the entire period of consolidation or require mandatory intermaxillary fixation, the lower jaw is fixed in the central occlusion position, which is not a position of physiological rest, and leads to passive muscle tension. depriving them of active function. The main disadvantage of the methods of osteosynthesis using a suture and using wires is that it is difficult to achieve stable fixation of fragments using these techniques. Combined methods of fixation of bone fragments (use of a bone suture and dental splints) provide a stronger fixation of the fragments. In the past two decades, in the treatment of mandibular fractures, there has been an increase in the trend towards rigid or semi-rigid osteosynthesis using plates. The disadvantages of compression osteosynthesis is that significant compression can lead to ischemia and slow down the formation of callus. A common disadvantage of conservative and surgical methods of treatment is unstable fixation of bone fragments, which is the most common reason for their delayed consolidation. Bone osteosynthesis with metal plates is considered a more progressive method of treating mandibular fractures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
