Abstract
IntroductionEven though is rarely, mandibular fracture after the extraction of third molars can occur in almost 1% of the procedures. Gender, age, position of third molar, tooth volume, bone fragility, systemic disorders, associated lesions, and degree of mandibular atrophy are factors that contribute to increase the incidence of fracture. The installation of the titanium miniplate during exodontia is an important tool to prevent the fracture.Presentation of caseThe objective of this study is to present a clinical case of extraction of inferior impacted third molar, in atrophic mandible, with posterior installation of titanium miniplate, to prevent mandibular fracture.Discussion and conclusionpreventive installation of titanium miniplate was effective and indeed prevented the mandibular fracture. No trans-operative or immediate post-operative complications were observed. Post-operative follow-up was of three years, with no complications, showing the success of the procedure.
Highlights
Even though is rarely, mandibular fracture after the extraction of third molars can occur in almost 1% of the procedures
Inferior third molar extraction is the most performed procedure by oral maxillofacial surgeons, it may be associated with several complications: alveolitis, hemorrhage, infection, paresthesia, trismus and rarely mandibular fracture [1,2]
Mandibular fracture is a uncommon complication, with low incidence after third molar extraction (< 1%). It is more frequently described in the literature in male patients, above 40 years old, presenting systemic disorders, with large tooth volume and in impacted position
Summary
Inferior third molar extraction is the most performed procedure by oral maxillofacial surgeons, it may be associated with several complications: alveolitis, hemorrhage, infection, paresthesia, trismus and rarely mandibular fracture [1,2]. Mandibular fracture is a uncommon complication, with low incidence after third molar extraction (< 1%) It is more frequently described in the literature in male patients, above 40 years old, presenting systemic disorders (hyperparathyroidism and Pajet disease), with large tooth volume and in impacted position (class II and III, type B and C, according to Pell and Gregory classification – 1933). It is usually associated with atrophic mandible with impacted lower third molar (associated or not with bone cyst or tumors) [3]. This work has been reported according to the SCARE criteria [5]
