Objective: Osteogenesis imperfecta (OI) is a group of inherited disorders characterized by low bone mass, bone fragility and bone fracture. Bone, sclera, tendon and ligament are the main structures which contain type 1 collagen. Therefore, the first signs and symptoms of OI are related to these structures. Patients with OI commonly suffer from long bone fractures due to mechanical 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 pain and 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 left mandible body fracture involving the extraction socket. Conservative treatment was preferred considering the systemic condition of the patient. The patient was advised to protect the mandible from trauma and to be fed with a soft diet. During the 6-month follow-up of the patient, no clinical or radiological features of malocclusion were observed. Conclusion: Iatrogenic fracture can be minimized by careful evaluation of the patient before tooth 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 the bone during tooth extraction.
