Abstract
Introduction: The treatment of atrophic jaw fractures requires extensive knowledge by the maxillofacial surgeon. The correct diagnosis and planning optimize the possibility of oral rehabilitation towards many possible alternatives. The difficulty in repairing these fractures makes the treatment complex, in which normally invasive techniques are used. However; which give us satisfactory and predictable aesthetic-functional results. Objective: The objective of this work is to report an atrophic jaw fracture and posterior dental implants rehabilitation. Case report: A 53 years old female patient, victim of in face aggression referred to the emergency care. At the clinical examination, the patient had laceration in the upper lip region and the left side of the mandibular area, with bilateral mobility and paresis. In the oral examination, total lower and partial upper edentulism. After tomographic evaluation, a bilateral fracture of the mandibular body was confirmed, with significant bone fragments uneven. Surgery was performed with total transcervical access and use of reconstruction plate. After 90 days of follow-up, the oral rehabilitation with osseointegrated implants was performed. Conclusion: Complex atrophic mandible fractures in total edentulous patients can be treated with open reduction and stable fixation, allowing a faster return to normal function, improve of quality of life and assists in increasing safety for implant installation.KeywordsEdentulous jaw; Jaw fixation techniques; Dental implants.
Highlights
The treatment of atrophic jaw fractures requires extensive knowledge by the maxillofacial surgeon
Mandibular atrophy caused by edentulism represents a greater risk of fractures in the mandibular bone due to a decrease of bone mass associated with lower resistance and resilience [2]
Atrophic jaw fractures present a challenge for the surgeon because there is a need to promote osteosynthesis with reduction and bone immobilization in areas of small volume [2]
Summary
The treatment of atrophic jaw fractures requires extensive knowledge by the maxillofacial surgeon. Atrophic jaw fractures present a challenge for the surgeon because there is a need to promote osteosynthesis with reduction and bone immobilization in areas of small volume [2]. This type of fracture often occurs in elderly edentulous patients, in whom anatomical and physiological changes affect the prog-nosis negatively [2,3] In last few years there has been a great evolution in the surgical approaches, in which we observe gradual substitutions of closed techniques by open techniques [3,4]. The literature has shown better results when more aggressive approaches are chosen [5,6]
