ABSTRACT A 19-year-old female came to our department with the chief complaint of facial asymmetry. Clinical examination showed skeletal class III relationship with mandibular prognathism, large reverse overjet, lower right mild crowding, and left hemimandibular elongation. After a thorough discussion with the patient, she accepted the proposal of orthognathic surgery and mandibular setback by bilateral sagittal split osteotomy (BSSRO), and therefore, tooth extraction was performed for 18, 28, 38, and 48 before the surgery. An improved superelastic Ti-Ni alloy wire (ISW wire), developed by Tokyo Medical and Dental University, was then used to facilitate the correction of lower crowding. Involved mechanism included intermaxillary elastics for a better interdigitation and jaw relationships. Adequate overbite and overjet were achieved after treatment completion.

ABSTRACT Skeletal class III with anterior crossbite is a very common orthodontic problem in Taiwan. Early diagnosis and treatment are very important to achieve effective correction. This article reports the treatment outcomes using improved superelastic TiNi alloy wire (ISW; developed by Tokyo Medical and Dental University) for a case of skeletal class III malocclusion with anterior crossbite and lower anterior crowding combined minor facial asymmetry. ISW allowed relief of crowding to facilitate correction for this case. In comparison with the traditional treatment with SSW multiple L loops of class III patient, ISW multiloop edgewise archwire (MEAW) can provide a more efficient and easier way for the patient. After 16 months of treatment, a desirable outcome was achieved and patient was satisfied with the treatment procedure and result. How to cite this article Tseng CH, Jian-Hong YU.

VG, 25-year-old male, presented with c/c of forwardly placed lower jaw and history of unsatisfactory previous orthodontic treatment. Extraorally, the patient had asymmetrical face and concave profile, competent lips, positive lip step, and chin deviated toward left side by 2 mm. Intraorally, the patient had Angle’s class III type 3 malocclusion with an overjet of (–1) mm, overbite of 0%, and cross-bite wrt 12, 21. The patient was skeletal class III due to macrognathic and prognathic mandible with hypodivergent growth pattern, and proclined upper and retroclined lower incisors. The patient was managed orthosurgically with bimaxillary surgery (maxillary advancement 3 mm + mandibular setback 7 mm) after presurgical decompensation. The case report discusses in detail the diagnosis and comprehensive management of the skeletal class III case.

Traditional orthognathic surgery has long been performed after presurgical orthodontic treatment. Despite some concerns, the surgery-first orthognathic approach (SFOA) or surgery-first approach (SFA) without presurgical orthodontic treatment has gradually gained popularity. In recent years, several articles dealing with the concepts of the SFA have been published worldwide. However, the SFA has not yet been standardized, and many surgeons use slightly different protocols and concepts. This review article discusses the beginning and evolution of the SFA and its current concepts, including some opinions based on the authors’ clinical experiences over the last 15 years. According to recent investigations, the SFA could be applied effectively in several situations including class III malocclusion, class II malocclusion, and facial asymmetry. However, debate on the SFA continues and many issues remain to be resolved. This review article addresses the current issues regarding the SFOA, including its advantages and disadvantages, as well as its indications and contraindications. The authors summarize various aspects of the SFA and expect that this review article will help surgeons and orthodontists better understand the current status of the SFA.
