“…Use of split with intermaxillary fixation may be useful. Three-dimensional fixation or immobilization can therefore be gained by using miniplates superiorly on the bony aspect, a dressing plate on the palatal aspect, and a wired-in final surgical wafer on the occlusal aspect of the dentoalveolar segments [36]. If nonunion occurs the surgical site should be reopened, fibrous tissue removed and proper rigid fixation be used for predictable union of segments.…”

“…In LeFort I, the risk of damage to the teeth roots increases when the horizontal osteotomy line is 5 mm or less. Close proximity to interdental osteotomy cuts or to screws may cause tooth damage, and pulp necrosis [36].…”

“…The central incisors and teeth that are distant from the vertical osteotomy have blood flow without significant change [37]. It is advocated that presurgical orthodontic separation of the roots by at least 2 mm at the cementoenamel junction and 4 mm at the apical third be maintained to avoid vascular compromise or damage to the roots adjacent to interdental osteotomies [36].…”

Orthognathic surgery is a common approach for treatment of maxillofacial deformities. Sagittal split ramus osteotomy (SSRO) is one of the most common techniques used to treat various mandibular deformities. A LeFort I osteotomy is suggested in deformities of the maxilla and can be used along with SSRO or intra-oral vertical ramus osteotomy (IVRO).The aim of orthognathic surgery is to improve function and facial appearance; this benefits the patient psychologically and socially. Common complications which may occur in orthognathic surgery include vascular disease, temporomandibular joints (TMJ) problems, nerve damage, infection, bone necrosis, periodontal disease, vision impairment, hearing problems, hair loss, and neuropsychiatric problems. Rarely complications could be fatal. Because of the wide range of complications the surgeon should keep prevention protocols in mind and be prepared to treat them should they occur. In this chapter, common complications of various osteotomies in the mandible and maxilla are discussed.

“…In another study, Bamber and Harris (1995) reported no difference found between the thick and the thin wafers in 74 percent of the patients [7]. Segmental Le Fort I maxillary osteotomy is a beneficial technique in the management of transverse and vertical maxillary discrepancies [8] as well as the correction of malocclusion and maxillomandibular deformities [9]. Also, Le Fort I allows for movement in all three planes [9].…”

Background: Osteotomy wafers were routinely used in orthognathic surgery for repositioning the mobilized maxilla to achieve the planned final occlusion. Objectives: The aim of the current study was to determine comparison of thick and thin intermediate wafer in maxillary Le Fort I osteotomies. Methods: This study was done in 9 patients who had maxillary prognathism or retrognathism abnormality. The maxillary cast was oriented using articulator after facebow transfer. Then photographic and cephalometric data was used to determine proper dental arch segments. All 9 patients had Le Fort I combined with mandibular sagittal split osteotomies. The Le Fort I surgery was done on lateral, septum and medial sinus of nasal and trigomaxillary. The cast was removed from the base articulator and think and thick wafers were fabricated for each. Then the wafers were fixed in 1, 2 and 3 mm anterior (A 1 , A 2 and A 3 , respectively). After mobilization of the maxilla and adequate bone removal, the jaws were held in occlusion with the thin intermediate wafer. The maxilla was then located against the stable part of the facial skeleton above using the yet unoperated mandible as an autorotated guide. Then the superior reposition >1 or <1 m between two wafers was determined. Results: According to the results, the superior reposition was higher in thin wafers fixed in A 3 > A 2 compared to A 1 . Also, the same result was detected in thick wafers fixed in A 3 > A 2 compared to A 1 , respectively. However, there was no significant difference in both thin and thick wafers in each fixed locations. Conclusion: These results suggest thick wafers have acceptable results in maxillary Le Fort I osteotomies.
