No obvious difference in complication was found between these two kinds of fixations. However, marked differences occurred 6 monthes later in (1) rates of loss of body weight (more than 10kg) and (2) persistent restriction of mandibular opening (incisal opening less than 35 mm). The two rates in WF group are 30% and 24% and in RIF group. 8%and 4% respectively The results demonstrate that early post-operative mobility of is helpful in rehabilitation of masticatory and movement of temporal mandibular joints(TMJ). Therefore RIF is recommended.展开更多

The senior author's(KES) experiences of more than 2000 patients with cleft lip and palate treated by a surgical-orthodontic protocol were introduced. The paper here will concentrate on not only correcting the occlusion as others have described,but also on what one surgeon can do to achieve optimal aesthetic balance, harmony and beauty. The results of orthognathic surgery in respect to function, stability, cosmesis, and complications are also audited.展开更多

This case report highlights the importance of the treatment plan for a patient initially treated with four-premolar-extraction camouflage, despite indications for orthognathic surgery.CASE SUMMARY A 23-year-old male sought treatment complaining about his unsatisfactory facial appearance. His maxillary first premolars and mandibular second premolars had been extracted, and a fixed appliance had been used to retract his anterior teeth for two years without improvement. He had a convex profile, a gummy smile, lip incompetence, inadequate maxillary incisor inclination, and almost a class I molar relationship. Cephalometric analysis showed severe skeletal class Ⅱ malocclusion(A point-nasion-B point = 11.5°) with a retrognathic mandible(sella-nasion-B point = 75.9°), a protruded maxilla(sella-nasion-A point = 87.4°), and vertical maxillary excess(upper incisor to palatal plane = 33.2 mm). The excessive lingual inclination of the maxillary incisors(upper incisor to nasion-A point line =-5.5°)was due to previous treatment attempts to compensate for the skeletal class Ⅱ malocclusion. The patient was successfully retreated with decompensating orthodontic treatment combined with orthognathic surgery. The maxillary incisors were repositioned and proclined in the alveolar bone, the overjet was increased, and a space was created for orthognathic surgery, including maxillary impaction, anterior maxillary back-setting, and bilateral sagittal split ramus osteotomy to correct his skeletal anteroposterior discrepancy. Gingival display was reduced, and lip competence was restored. In addition, the results remained stable after 2 years. The patient was satisfied with his new profile as well as with the functional malocclusion at the end of treatment.CONCLUSION This case report provides orthodontists a good example of how to treat an adult with severe skeletal class Ⅱ malocclusion with vertical maxillary excess after an unsatisfactory orthodontic camouflage treatment. Orthodontic and orthognathic treatment can significantly correct a patient’s facial appearance.展开更多
