Extraction of impacted third molar with preventive installation of titanium miniplate: Case report

INTRODUCTION: Even 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 CASE: The 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 CONCLUSION: preventive 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.
