Introduction: The revascularized fibula free flap (RFFF) is the most popular method of postmaxillectomy reconstruction. This article proves that the use of curvilinear transport distraction osteogenesis (CTDO) is an efficacious way in closing large defects in the maxilla and a superior alternative to the RFFF. Methods and Materials: In a prospective cohort study of six postmaxillectomy patients, CTDO was applied and the new bone (regenerate) was compared with the parent bone from which it had been regenerated. These results were compared with a retrospective group of six participants of similar age and sex who had undergone RFFF reconstruction as an external control. Clinical measurements taken at the depth of the alveolar vestibule were recorded at three different exact points juxtaposed, namely (A) lateral incisor, (B) first premolar, and (C) first molar. These areas of interest were similar to those chosen on the CT scans. Impressions were taken from all the patients and stone casts were made. The width of the alveolar bone was computed based on the measurements made from the stone casts. The stone casts were then used to calculate the width and depth of the soft tissue and bone in the maxilla in the (A), (B), and (C) regions. Results: The regenerate possessed anatomical and physiological characteristics equal to the parent bone. For the CTDO patients, prosthetic rehabilitation of the dentition was supported by dental implants after osseointegration of the latter into the newly created bone and soft tissue. Discussion: The production of the curvilinear bone and soft tissue along a horizontal plane has been demonstrated. The new alveolar bone achieved the correct width and depth to create a physiological vestibule and a functional/esthetic zone for the placement of dental implants. In addition, the shape of the palatal vault was also maintained. The CTDO method is a reliable method of maxillary reconstruction and has a better anatomical and functional outcome than the RFFF.
