摘要
purpose: This report describes the application of an intraoral device for treatment of malocclusions characterized by mandibular deficiency and the surgical technique for its placement. Patients and Methods: In an office setting, 5 retrognathic patients underwent mandibular lengthening via distraction osteogenesis with an intraoral tooth-borne distraction device. Under local anesthesia and sedation, mandibular corticotomies, mobilization, and placement of the distracters were performed. Preoperative, intradistraction, and postoperative dental casts, photographs, and cephalometric radiographs were used to analyze the results. Results: In 3 of the 5 cases, distraction occurred along the planned vector. The remaining 2 cases showed opening rotations of the mandibular anterior segment along with the advancement. Conclusions: This study documents that the mandible and the dental arch can be lengthened successfully using this technique.
