Introduction: Distraction osteogenesis is a biological phenomenon characterized by the formation of new bone between segments that are gradually separated by increasing tension. mandibular midline distraction anterior It is an alternative method used in the treatment of mandibular transverse insufficiency characterized by dental crowding. Although it is an easy and effective method, complications such as wound dehiscence and nerve damage may occur.
Case Presentation:A 14-year-old female patient applied with the complaint of mandibular stenosis. Anterior dental crowding was detected in the clinical and radiological examination. The patient was operated under general anesthesia. The osteotomy was performed between the lower central incisors. After the osteotomy line was created, the screw was turned a few turns and a complete separation was observed. The mental muscle was observed to be completely separated. The mucosa was sutured with a resorbable suture and a non-resorbable suture. The patient was bandaged for 3 days to reduce swelling at the chin tip.
Conclusion: In mandibular transverse deficiencies, the stenosis can be resolved without tooth extraction by increasing the transverse width with fixed orthodontic treatment following lower jaw distraction. Mandibular dental expansion gives more permanent results than dental expansion appliances when supported by skeletal expansion. Mandibular midline distraction seems to be a reliable method.
