Abstract This article reports the case of a 44-year-old male with skeletal Class III, Angle Class III malocclusion and unilateral crossbite with concerns about obstructive sleep apnea syndrome (OSAS), esthetics and functional problems. To correct the skeletal deformities, the maxilla was anteriorly repositioned by employing LeFort I osteotomy following pre-surgical orthodontic treatment, because a mandibular setback might induce disordered breathing and cause OSAS. After active treatment for 13 months, satisfactory occlusion was achieved and an acceptable facial and oral profile was obtained. In addition, the apnea hypopnea index (AHI) decreased from 18.8 preoperatively to 10.6 postoperatively. Furthermore, after a follow-up period of 7 months, the AHI again significantly decreased from 10.6 to 6.2. In conclusion, surgical advancement of the maxilla using LeFort I osteotomy has proven to be useful in patients with this kind of skeletal malocclusion, while preventing a worsening of the OSAS.

Abstract Although accurate bracket placement is essential for orthodontic treatment, many practitioners apply brackets indiscriminately with direct or indirect bonding techniques. Nonetheless, there have been few prospective clinical comparisons of the 2 techniques. We will therefore conduct a single-center, randomized control trial in 100 patients aged ≥12 years and diagnosed with malocclusion. All patients will receive orthodontic treatment using brackets with direct or indirect bonding techniques. The primary endpoints will be the total treatment time, occlusal index, discomfort at bonding, and oral hygiene after bonding. This study will clarify whether indirect bonding can improve the efficiency of orthodontic treatment.

Abstract We herein report the case of a 19-year-old female with a transverse discrepancy, skeletal Class II malocclusion, severe crowding with concerns of classic-type Ehlers-Danlos syndrome (EDS), aesthetics problems and functional problems. The main characteristics of classic EDS are loose-jointedness and fragile, easily bruised skin that heals with peculiar “cigarette-paper” scars. The anteroposterior and transverse skeletal discrepancies can generally be resolved by maxilla repositioning and mandibular advancement surgery following pre-surgical orthodontic treatment. However, this patient was treated with orthodontic camouflage but not orthognathic surgery because of the risks of skin bruising, poor healing and a temporomandibular disorder. A satisfactory dental appearance and occlusion were achieved after camouflage treatment with orthodontic anchor screws and the use of Class II elastics, including the preservation of the stomatognathic functions. Acceptable occlusion and dentition were maintained after a two-year retention period. This treatment strategy of orthodontic camouflage using temporary anchorage, such as anchor screws and Class II elastics, may be a viable treatment option for skeletal malocclusion patients with EDS.

Abstract Appropriate operations in severe anterior open bite (AOB) cases are extremely complicated to perform because of the multiple surgical procedures involved, the difficulty of predicting posttreatment aesthetics, and the high relapse rate. We herein report a 16-year-old girl with skeletal Class II, severe AOB malocclusion, and crowding with short roots, and aesthetic and functional problems. Four-piece segmental Le Fort I osteotomy with horseshoe osteotomy was performed for maxillary intrusion, and bilateral sagittal split ramus osteotomy (SSRO) and genioplasty were performed for mandibular advancement. The malocclusion and skeletal deformity were significantly improved by the surgical orthodontic treatment. Functional and aesthetic occlusion with an improved facial profile was established, and no further root shortening was observed. Acceptable occlusion and dentition were maintained after a two-year retention period. This strategy of surgical orthodontic treatment with a complicated operative procedure might be effective for correcting certain severe AOB malocclusion cases.
