Abstract

This case report describes skeletal anchorage-supported maxillary protraction performed with the Alternate Rapid Maxillary Expansion and Constriction (Alt-RAMEC) protocol over a treatment duration of 14 months in a 16-year-old female patient who was in the late growth-development period. Miniplates were applied to the patient's aperture piriformis area to apply force from the protraction appliance. After 9 weeks of following the Alt-RAMEC protocol, miniplates were used to transfer a unilateral 500-g protraction force to a Petit-type face mask. A significant improvement was observed in the soft tissue profile in measurements made both cephalometrically and in three dimensional photographs. Subsequently, the second phase of fixed orthodontic treatment was started and the treatment was completed with the retention phase. Following treatment completion, occlusion, smile esthetics, and soft tissue profile improved significantly in response to orthopedic and orthodontic treatment.

使用Alt-RAMEC方案和骨骼锚固矫治晚期青少年骨骼III类。

本病例报告描述了一名16岁晚期生长发育的女性患者，采用上颌快速扩张和收缩交替(Alt-RAMEC)方案，在14个月的治疗期间，采用骨锚支架支持的上颌牵引。将微型钢板应用于患者梨状肌孔区域，以施加牵引器产生的力。按照Alt-RAMEC方案治疗9周后，使用微型钢板将单边500g拉力转移到petit型口罩上。在头部测量和三维照片中观察到软组织轮廓的显着改善。随后，开始第二阶段固定正畸治疗，并以固位期结束治疗。治疗完成后，矫形和正畸治疗对咬合、微笑美观和软组织轮廓有显著改善。

期刊介绍： The Korean Journal of Orthodontics (KJO) is an international, open access, peer reviewed journal published in January, March, May, July, September, and November each year. It was first launched in 1970 and, as the official scientific publication of Korean Association of Orthodontists, KJO aims to publish high quality clinical and scientific original research papers in all areas related to orthodontics and dentofacial orthopedics. Specifically, its interest focuses on evidence-based investigations of contemporary diagnostic procedures and treatment techniques, expanding to significant clinical reports of diverse treatment approaches. The scope of KJO covers all areas of orthodontics and dentofacial orthopedics including successful diagnostic procedures and treatment planning, growth and development of the face and its clinical implications, appliance designs, biomechanics, TMJ disorders and adult treatment. Specifically, its latest interest focuses on skeletal anchorage devices, orthodontic appliance and biomaterials, 3 dimensional imaging techniques utilized for dentofacial diagnosis and treatment planning, and orthognathic surgery to correct skeletal disharmony in association of orthodontic treatment.
