관악기는 앙부슈어를 취해 연주하므로 다른 악기들과 구분이 된다. 입 주위의 근육과 골격, 치아, 입술, 혀가 연주에 능동적으로 참여하는 것이다. 더불어 폐로부터의 호흡이 악기에 전달되고 두 손이 운지를 담당하므로 취주는 호흡과 앙부슈어, 운지를 완수하기 위한 근신경계의 능동적인 프로세스라고 정의할 수 있다. 악기 연습과 공연 연주가 이 복잡한 프로세스를 집중하므로 과하게 반복된 동작은 앙부슈어 관련 신체구조에 질환과 외상을 유발하기도 한다. 이에 본 연구는 국내외 취주악기 연주자 질환 보고에 대한...

Objective: The purpose of this study was to clarify the effects of continuous force application for extrusive tipping movement and occlusal interference on periapical root resorption in the rat mandibular first molar. Methods: We constructed an appliance comprising a titanium screw implant with a cobalt– chromium post as the anchorage unit and a nickel–titanium closed coil spring (50 cN) as the active unit. Force was applied on the mandibular left first molar of rats for 8 (n = 10)...

Objective: The purpose of this study was to analyze initial displacement and stress distribution of the maxillofacial complex during dentoskeletal maxillary protraction with various appliance designs placed on the palatal region by using three-dimensional finite element analysis. Methods: Six models of maxillary protraction were developed: conventional facemask (Type A), facemask with dentoskeletal hybrid anchorage (Type B), facemask with a palatal plate (Type C), intraoral traction using a...

in the bone–implant contact (BIC, %) among the root proximity groups and loading time groups were determined using statistical analyses. Results: No BIC was observed within the bundle bone invaded by the miniscrew threads. Narrowing of the periodontal ligament space was observed in cases where the miniscrew threads touched the bundle bone. BIC (%) was significantly lower in the high root proximity group than in the low root proximity and safe distance groups. However, BIC (%) showed no...

The purposes of this study were: 1) to determine the? normal range of CR-CO discrepancy in normal occlusion group: 2) to evaluate the changes of condylar position and craniofacial morphology between centric relation and centric occlusion before and after stabilization splint therapy in malocclusion group outside the normal range of CR-CO discrepancy. The normal occlusion group consisted of 80 subjects who had well-balanced faces and good occlusions with acceptable Class I molar relationship....

하악 전치의 밀집은 가장 흔히 볼 수 있는 부정교합의 특징중의 하나이며 교정치료후의 안정성과 재발 측면에서도 중요 관심의 대상이다. 이를 유발시킬 수 있는 원인으로 그동안 많은 요소가 연구되어 왔으며 치아의 크기도 그 중의 하나이다. 현재 교정치료의 진단과 치료에 사용되고 있는 치아 크기 측정에서는 순설측 폭경의 의미가 간과되어 왔는데 Peck과 Peck이 이상적인 하악 전치부 배열을 가진 경우 절치의 근원심 폭경은 평균보다 작고 순설측 폭경은 평균보다 크다는 통계학적 수치를 발표하고 MD/FL index가 하악 전치부...

The lingual multibracket appliance was developed to overcome the unesthetic nature of traditional fixed orthodontic labial appliances; however, treatment with this appliance was regarded as very difficult as well as a time-consuming. Recently, these problems have been reduced because of advances in lingual bracket systems, improved indirect bonding technique and the development of more flexible wires. There has been a marked increase in the number of adults desiring orthodontic treatment over...

Three-dimensional finite element model was made from adult skull to find desirable direction of retraction force to treat skeletal class II malocclusion. The retraction force of 400g was applied to the first molar. The direction of the force application was 23° downward, parallel, 23° upward and 45` upward to the occlusal plane. The stress distribution and the displacement within the maxilla were analyzed by three-dimensional finite element method. The findings obtained were as follows: 1....

was a large angle between crown axis and root axis, and if we valued only the position of crown in establishing occlusal relationship without considering of the situation of root, the problem of root arrangement between adjacent teeth would be occurred. The estimate of root parallelism in mesiodistal direction before and after orthodontic treatment must be emphasized. The intent of this study was to determine the clinical importance and correlation of the angle between crown axis and root axis....
