Patients with considerable maxillomandibular anteroposterior discrepancies and maxillary hypoplasia, require corrective treatment through orthognathic surgery. However, in the treatment of severe maxillary retrognathism, it is necessary to reconstruct the areas of bone deficiency through grafting techniques in addition to maxillary advancement using only the Le Fort I osteotomy. Treatment in these patients is more challenging and requires high surgical predictability. Alloplastic materials have often been used for the reconstruction of poor bone contours. Ultrahigh molecular weight polyethylene (UHMWPE) is currently an excellent alternative as a filler material for poor bone regions and is a good substitute for autografts and other alloplastic materials for their unique properties, including high biocompatibility. The insertion of this material in the fixation system customized in orthognathic surgeries planned virtually is an innovative technique. This paper describes an association of UHMWPE inserted into the custom-made titanium miniplates manufactured by CAD-CAM (computer-aided desing/computer-aided manufacturing) technology in a surgery orthognathic of maxillary advancement and mandibular retrusion to treat a patient with Crouzon's syndrome with class III malocclusion and severe maxillary retrognathism.
