다수의 매복치 및 과잉치를 동반한 쇄골두개이형성증 환자에서 골내고정원 및 악간견인을 이용한 교정치료

Cleidocranial dysplasia (CCD) is a genetic skeletal condition with autosomal dominant inheritance. It is characterized by various skeletal and dental abnormalities, such as missing clavicles, hypoplastic maxilla, retained deciduous teeth, and supernumerary and impacted permanent teeth. In such patients forced eruption of impacted teeth tends to be challenging due to the limited osteogenesis. The present case illustrates the orthodontic and surgical management of a 15-year-old female patient with CCD accompanied by multiple supernumerary and impacted teeth using intermaxillary traction and bone-borne anchorage. After the surgical opening of the impacted teeth, a miniscrew-assisted rapid palatal expander (MARPE) was delivered in combination with a facemask for anteroposterior and transverse development of the maxilla. Following the maxillary expansion, a fixed appliance was bonded sequentially, first in the maxilla and then in the mandible for space regaining and eruption of the impacted teeth. Supernumerary teeth were removed successively during the treatment. The treatment was completed after 31 months with successful eruption and alignment of the impacted teeth, and the 3-year-follow-up showed satisfactory posttreatment stability. As shown in the present case, early diagnosis and timely orthodontic and surgical interventions are crucial to avoid further skeletal and dental complications and to facilitate aesthetic and functional rehabilitation in patients with CCD.

Tooth transposition is an anomaly of eruption characterized by the interchanged positions of two adjacent teeth, which is divided into complete and incomplete transposition. There are three common approaches for treating transposition: aligning the involved teeth in their transposed positions, moving them to their correct anatomic position in the arch and extracting one of the transposed teeth. Considerations in treatment plans are esthetic, function, risk of jeopardizing the roots and damaging the supporting structures, position of the root apex, developmental stages of teeth and expected compliance. The presented case reports described one maxillary canine-the first premolar transposition and two mandibular lateral incisor-canine transpositions. The former transposed teeth were arranged in their transposed position, and the latter transposed teeth were rearranged into their normal position. 치아전위란 인접한 두 치아의 위치가 서로 바뀐 치아 위치 이상을 말하며, 치관과 치근의 위치에 따라 완전전위와 불완전전위로 나눌 수 있다. 하악보다는 상악에 편측성으로 호발하며, 특히 상악 견치에서 자주 발생한다. 전위는 발견 시기와 전위된 양상에 따라 치료방법이 달라질 수 있다. 본 증례는 상악 견치와 제1소구치 간의 전위가 일어난 10세 7개월의 환아와 하악 측절치와 견치 간의 전위가 일어난 8세 11개월 환아와 8세 9개월 환아의 교정치료에 대한 것으로 양호한 치료 결과를 얻었고, 증례 별로 치료방법의 차이점에 관한 고찰을 하였기에 이를 보고하는 바이다.
