초록
교정치료에는 치아를 움직이는 치열교정치료와 골격적인 이동을 도모하는 악정형 치료가 있다. 소아청소년기 아동에서 특히 악정형 치료를 위해서는 골 성숙도와 성장 잠재력의 평가가 매우 중요하다. 본 연구의 목적은 613세 정상 교합 아동을 대상으로 측모 두부 규격 방사선사진과 수완부골 방사선사진을 촬영하여 발달 단계를 평가하고 하악골 성장량을 비교한 것으로 다음과 같은 연구결과를 얻었다. SMI와 CVM은 유의한 상관관계를 나타냈다(p < 0.05). 수완부골 성숙도가 증가할수록 Ar-Go, Co-Go, N-Go, S-Gn,N-Me, Co-Gn, Go-Me, Go-Gn이 증가하였고, 경추골 성숙도가 증가할수록 Ar-Go, Co-Go, N-Go, S-Gn, N-Me, Co-Gn, Go-Me, Go-Gn이 증가하였다. 또한 Ar-Go, Co-Go, N-Go, S-Gn, N-Me, Co-Gn, Go-Me, Go-Gn은 경추 및 수완부골 성숙도와 각각 유의한 상관성을 보였다(p < 0.05). 이상의 결과로 하악골 성장은 경추 및 수완부골 성숙도와 유의한 상관성이 있음을 알게 되었다.
Abstract
There are orthodontic treatment which involves tooth movements and orthopedic treatment which involves skeletal movement. In childhood and adolescence, especially for the treatment of orthopedic treatment, the evaluation of bone maturity and growth potential is very important. The purpose of this study is to assess the developmental stage and to compare the amount of mandibular growth with cephalometric radiographs and hand-wrist radiograph in 6 to 13-year-old children with normal occlusion. The results are as follows :SMI and CVM showed a significant correlation (p < 0.05). Ar-Go, Co-Go, N-Go, S-Gn, N-Me, Co-Gn, Go-Me,Go-Gn increased with increasing maturity of hand-wrist and Ar-Go, Co-Go, N-Go, S-Gn, N-Me, Co-Gn, Go-Me, Go-Gn increased with increasing maturity of cervical vertebrae maturation. Also Ar-Go, Co-Go, N-Go, SGn,N-Me, Co-Gn, Go-Me, Go-Gn showed a significant correlation with each of the cervical vertebrae maturation stages and hand-wrist maturation stages (p < 0.05). These results suggested that mandibular growth had a significant correlation with cervical vertebrae maturation stages and hand-wrist maturation stages.
