Correction of Mandibular Asymmetry Due to Hemifacial Microsomia Using a Custom-made Implant

Custom-trade artificial bone produced by the figurative lithographic method based on 3-dimensional computed tomography data is now available as a compatible and reliable implant. We describe a patient with hemifacial microsomia who was treated with custom-made artificial bone, trade from hydroxyapatite, for facial symmetry. Using the implant was less invasive surgically and shortened the operating time. A full-scale model and template were created using the binder jet method and 3-dimensional computed tomography images reformatted with single-helical scan data. These technologies were useful for producing the custom-made implant and explaining the procedure to the patient perioperatively. A symmetrical profile of the patient's face has been maintained without any resorption of the implant and graft bed for 3 years. The hydroxyapatite custom-made implant was effective for facial rehabilitation in the treatment of mandibular asymmetry due to hemifacial microsomia.
