Self-designed Three-dimensional Printed Skeletal Anchorage Titanium Device for Orthopaedic Traction in a Growing Class III Patient

Abstract

<p>Maxillary retrusion in a growing skeletal class III patient can be treated with growth modification by facemask therapy with skeletal anchorage. A 12-year-old boy presented with Skeletal Class III relationship, retrognathic maxilla and paranasal deficiency. Cone beam computer tomography (CBCT) was taken for the design of the customized skeletal anchorage device with a 3D planning computer software. Two pairs of skeletal anchorage surgical guides and plates were designed with the correct vector and location, and to avoid tooth roots in the fixation. The plates were printed with titanium and fixed onto the patient for the facemask therapy. CAD-CAM technology allows customization and precise execution of the skeletal anchorage for the facemask therapy. Self-designed 3D printed skeletal anchorage device, with the advantages of increased rigidity, ease of placement and accuracy of force application, can be a valid alternative to stock titanium plates.<br></p>
