Spontaneous Healing Of The Iatrogenic Mandibular Fracture After Molar Extraction In A Patient With Undiagnosed Osteogenesis Imperfecta: A Case Report

Objective: Osteogenesis imperfecta (OI) is a group of inherited disorders characterized by lowbone mass, bone fragility and bone fracture. Bone, sclera, tendon and ligament are the mainstructures which contain type 1 collagen. Therefore, the first signs and symptoms of OI arerelated to these structures. Patients with OI commonly suffer from long bone fractures due tomechanical loading. Facial fractures are very rare in patients with such disorder.Case: A 34-year-old male patient was consulted to our clinic with complaints of severe painand paresthesia in the left mandible after the extraction of the left mandibular first molar. Ortopanoramic radiography and Cone-Beam Computed Tomography (CBCT) showed an isolated leftmandible body fracture involving the extraction socket. Conservative treatment was preferredconsidering the systemic condition of the patient. The patient was advised to protect themandible from trauma and to be fed with a soft diet. During the 6-month follow-up of thepatient, no clinical or radiological features of malocclusion were observed.Conclusion: Iatrogenic fracture can be minimized by careful evaluation of the patient beforetooth extraction. From clinical point of view, patients with OI suffer from fragile bones.Therefore, it is recommended sectioning the tooth to prevent excessive force applied to thebone during tooth extraction.
