Case Report: Corticotomy-Facilitated Anterior Teeth Retraction in Bimaxillary Protrusion Patients

Abstract

Objective: To describe a corticotomy-facilitated en-masse retraction of anterior teeth in anatomical limited bimaxillary protrusion patient.
Treatment plan: Four first premolars extraction to reduce anterior teeth and lip protrusion. After leveled and aligned until completed on 0.016” X 0.022” stainless steel wire, the patient was treated with corticotomy and bone graft. Two weeks later, retracted canines and anterior teeth with T-loop until the space were closed.
Result: The anterior retraction beyond anatomical limit, upper and lower anterior teeth normal inclination and position. The facial profile was improved. Lips became competent at rest position.
Conclusion: This case report showed the outcome of corticotomy-facillitated orthodontic treatment in a patient who refused orthognathic surgery. A careful plan and the other choice that awareness of possible side effects in every step of treatment is essential to obtain maximum intercuspation for function, stability and esthetic under the limitation of skeletal structure.
