전현상,최갑림,임성훈,김광원 대한치과교정학회 2008 대한치과교정학회지 Vol.38 No.4

본 연구는 파노라마 방사선사진에서 두부 위치 변화에 따라 인접 치아장축 사이에 이루는 각도가 어떻게 변화되는 지 알아보기 위해 시행하였다. 정상교합자의 모델을 기초로 하여 3차원 solid 모델을 구성하고 이를 신속 조형모델(rapid prototyping, RP)로 제작하였다. 다음 9가지 두부위치들을 5주 동안 일주일 간격으로 재위치시키고 촬영하였다: ideal head position, 5^(o), 10^(o) up, 5^(o), 10^(o) down, 5^(o), 10^(o) right up, and 5o,^(o) 10^(o) right rotation. 파노라마 방사선사진 촬영은 디지털 방사선 촬영기(Planmeca ProMax)를 이용하였고 모니터상에서 직접 인접 치아장축을 표시하고 그 사이 각도를 계측하였다. 그 결과 이상적인 두부 위치와 다양한 두부 위치 변화에 따라 촬영한 파노라마 방사선사진 사이에 인접 치아장축 사이의 각도가 대부분 유의한 차이를 보였다. 수평축(X축)을 중심으로 고개를 든 경우, 각 치아 들의 장축이 교합평면을 향하여 수렴하는 경향을 보였고 고개를 숙인 경우에는 치근단측을 향하여 수렴하는 경향을 보였으며, 이는 특히 전치부에서 가장 큰 차이를 보였다. 전후방축(Y축)을 중심으로 좌우측으로 고개를 기울인 경우, 교합평면이 올라간 쪽의 치아장축은 치근단측을 향하여 수렴하는 경향을 보였고 교합평면이 내려간 쪽은 교합평면을 향하여 수렴하는 경향을 보였다. 수직축(Z축)을 중심으로 고개를 좌우로 회전시킬 때, 고개를 돌린 쪽의 측절치와 견치는 치근단측을 향하여 수렴하고 반대측의 측절치와 견치는 교합평면을 향하여 수렴하였다. 이상의 결과들로 볼 때 파노라마 방사선사진 촬영 시 두부의 위치 변화에 따라 치근 평행도가 달라지기 때문에 환자를 올바르게 위치시키는것이 중요하며, 교정 환자에서 파노라마 방사선사진을 이용하여 치근 평행도를 평가할 때 교합평면의 경사(전후방,좌우측방)나 악궁의 비대칭 등이 반드시 고려되어야 할 것이다. Objective: The purpose of this study was to evaluate the effect of head position changes on the root parallelism between adjacent teeth on panoramic radiographs. Methods: A model with normal occlusion was constructed in the SolidWorks program, then RP (rapid protyping) model was fabricated. The model was repeatedly imaged and repositioned five times at each of the following nine positions: ideal head position, 5^(o), 10^(o) up, 5^(o), 10^(o) down, 5^(o), 10^(o) right up, and 5o,^(o) 10^(o) right rotation. Panoramic radiographs were taken by Planmeca ProMax and the angle between the long axes of adjacent teeth was directly measured in the monitor. Results: Axes of adjacent teeth tended to converge toward the occlusal plane when the head tilted up and converged in the opposite direction to the occlusal plane when the head tilted down. Anterior teeth showed the most notable differences. When one side of the head tilted up 5o and 10o along the anteroposterior axis (Y axis), tooth axes of the same side tended to converge toward the occlusal plane and tooth axes of the opposite side tended to converge in the opposite direction to the occlusal plane. When the head rotated to one side along the vertical axis (Z axis), the canine and lateral incisor of the same side converged in the opposite direction to the occlusal plane and the canine and lateral incisor of the other side converged toward the occlusal plane. Conclusions: When assessing the root parallelism on panoramic radiographs, the occlusal plane cant (anteroposterior or lateral) or asymmetry of the dental arch should be considered because these can cause distortion of tooth axes on panoramic radiographs.

Continuous indentation test is getting more used to derive indentation flow curve. The overall deriving algorithm is relatively well-established, the details of the algorithm are, however, still argued. One of the arguments is the definition of true strain which constitutes the indentation flow curve. In this study, work-hardening exponent was adopted for determining what definition is appropriate to obtain accurate indentation flow curve since work-hardening exponent is affected by only the definition of true strain not by other constants. The effect of calibrating contact depth was eliminated using finite element analysis. Finally, the definition based on tangent function was determined to be proper for deriving the indentation flow curve. (Received September 8, 2004)

매복된 상악 견치를 위한 외과적 수술을 동반하는 교정치료는 주위조직에 손상을 주지 않고 치열궁내에 적절히 위치시켜야 한다. 이를 위해 매복된 치아의 위치에 따라 다양한 외과적, 교정적 방법이 소개되었으며, 그 방법으로 window procedure, apically positioned flap, closed eruption technique, tunnel traction 등이 있다. 깊은 골연하 매복에서 사용할 수 있는 방법으로 closed eruption technique 그리고 tunnel traction이 있는데, closed eruption technique은 점막 및 치은 하방으로 지나는 견인 와이어의 자극으로 염증 발생 가능성이 높으며 치은퇴축 및 부착 치은의 소실이 발생할 수 있다. 하지만, tunnel traction은 치아의 맹출이 터널을 통해서 유도되어 각화치은에 둘러싸인 채 치조골의 중앙으로 나오게 되므로 치은퇴축이나 치주부착의 소실 없이 적절한 각화치은을 얻을 수 있으며 매복치가 치조골의 중심부로 맹출함에 따라 생리적 맹출과 같은 효과 얻을 수 있다. 본 증례는 깊은 매복을 보이는 상악 견치를 tunnel traction을 이용한 치료를 보고한 것으로, 적절한 방향을 가지고 맹출하였으며 치은퇴축이나 부착치은의 소실이 발생하지 않았다. The impacted maxillary canine is a common problem of which all dental practitioners should be aware. The surgical orthodontic treatment of impacted canines is replaced correction position in dental arch without periodontal damage. Many treatment possibilities have been considered for this goal; window procedure, apically positioned flap, closed eruption technique and tunnel traction. Prognosis for these treatment may be very uncertain in many case(infraosseous impacted tooth). Other steps are required to achieve a satisfactory periodontal outcome. Satisfactory results could be expected if the physiologic eruption pattern is restored by tunnel traction, because permanent tooth erupts through the gingiva near the crest of the ridge so that periodontal damage is reduced. This article report that the surgical orthodontic treatment using tunnel traction is obtained proper position and reduced periodontal damage in facially impacted maxillary canines.

A bacterium producing five fibrinolytic isozymes was isolated from black bean chung kuk. The bacterium was identified as Bacillus subtilis BB-1 by 16s rDNA sequence homology search. A gene out of five fibrinolytic genes in the Bacillus subtilis BB-1 was cloned by shot-gun method. A Cla ⅠDNA fragment of B. subtilis BB-1 chromosome was cloned in to pBluescript ⅡSK(-) and showed the fibrinolytic activity to bacterial cells. The Cla ⅠDNA fragment was sequenced and the sequences did not show homology with gene for protease or fibrinolytic enzyme genes in other organisms. The Cla ⅠDNA fragment was reduced to 2,142 bp by activity-guided PCR cloning method. The optimum pH and temperature of the enzyme were 5.0 and 35℃, respectively. Substrate specificity of the fibrinolytic enzyme was detected in skim milk, casein, gelatin and blood agar plates. The activity of the enzyme was not detected with these substrates. Taken together, this enzyme is a new fibrinolytic enzyme and may be used to prevent thrombosis and arteriosclerosis.

Air-jet looms represent a major step in the development of shuttleless weaving because of their ability to weave a wide range of yarns at high speeds. Air-jet weaving involves inserting a pre-measured length of yarn through the wrap shed by means of compressed air. The analysis of air flow characteristic of the main nozzle and acceleration tube is necessary to loom performance. We examined the effect of the main nozzle with different acceleration tube as well as diameter. And also, we compared to the performance of straight type tube and laval type tube.
