Abstract

Odontogenic keratocysts (OKCs) are one of the most aggressive cysts in the oral and maxillofacial area because of their high recurrence rate and infiltrative behavior. In growing patients with OKCs, a radical treatment approach might cause numerous complications, including the disturbance of jaw growth and loss of the involved tooth. This case report describes successful comprehensive orthodontic treatment combined with marsupialization of the cyst in a young girl who exhibited an OKC with impacted teeth. The 10-year-old girl presented with an OKC extending from the mandibular symphysis through the left mandibular body, with ectopic impaction of the mandibular left canine and first premolar, as well as congenitally missing bilateral mandibular second premolars. Interestingly, spontaneous improvement of the positions of the ectopic impacted teeth, along with a reduction in the size of the cyst, occurred during marsupialization. The sequential use of removable and fixed appliances enabled orthodontic traction of the impacted teeth. The treatment outcome was stable at 2.5 years after the end of the treatment. We speculate that comprehensive orthodontic treatment combined with marsupialization can be an effective treatment strategy for patients with OKCs, especially when they are encountered in young, growing patients with impacted teeth.

年轻女孩患牙源性角化囊肿及下颌阻生牙的综合正畸治疗。
牙源性角化囊肿(Odontogenic keratocysts, OKCs)因其高复发率和浸润性而成为口腔颌面部最具侵袭性的囊肿之一。在生长中的OKCs患者中,根治性治疗方法可能会引起许多并发症,包括颌骨生长障碍和受损牙齿的脱落。这个病例报告描述了成功的综合正畸治疗结合囊肿有袋化在一个年轻的女孩谁表现出一个OKC与阻生牙齿。10岁女孩的OKC从下颌联合延伸到左侧下颌体,下颌左犬齿和第一前臼齿异位嵌塞,以及先天性双侧下颌第二前臼齿缺失。有趣的是,在有袋化过程中,异位阻生牙的位置随囊肿大小的减小而自发改善。连续使用可移动和固定的矫治器使阻生牙的正畸牵引成为可能。治疗结束后2.5年,治疗结果稳定。我们推测,综合正畸治疗结合有袋化可能是OKCs患者的有效治疗策略,特别是当他们遇到年轻,生长的阻生牙患者时。

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.
