LINGUAL ARCH APPLIANCE는 1908년 Mershon이 처음 창시한 교정장치로 band를 사용하는 교정장치중 가장 간단하면서도 여러가지 장점을 지니고 있다. 이 장치는 특히 성장발육기의 소아교정에 최적하여 치아의 기능을 제한하지 않으며 악골 및 치아의 자연적인 성장발육을 허용하고 자연적인 치아이동을 도모하게 한다. 또한 이 장치의 특징은 지속적인 교정치료보다는 간헐적인 치료를 한다는 사실이다.예를 들면 Angle씨 2 급부정교합 즉 상악전돌의 치료시는 상악에 Libial arch wire, 하악에 Lingual arch wire를 장착하고 여기에 악간고무를 이용하여 2급의 교합상태를 개선한후 수개월간 장치를 제거하여 치아의 자연적인 적응을 허용하고 다시 장치를 장착하여 치료를 계속하는 것이다.

$Fr{\ddot{a}}nkel$ functional regulator have a complicated design and are of a big bulk. This makes not only the construction of appliance but also the adaption of a patient to the appliance very difficult. Therefore, orthodontic laboratory technicians should be well acquainted with the sequential fabrication procedures involved in the construction of Frankel functional regulators and construct a type most suitable for a specific patient of malocclusion. There are various types of Frankel appliances. Detailed construction procedures of FR II are described here below, which can also be applied for other types for FR appliances.

The author observed the changes of dental arch dimensions and compared spae-maintainer group with non-space-maintainer group after primary tooth extraction. The results were as follows 1) The rate of growth of dental arch of expeirmental group in intercanine width and in inter-1st molar width was more rapid than that of the control group. 2) Arch length is almost no dimensions but it was slightly decreased in lower arch. 3) Dental arch growth and tooth eruption were stimulated by space-maintainer appliance, so it is the best way to replace a new appliance at least once a year. 4) It is thought that satisfactory conclusions in this observation must be researched successively until the mixed dentition completes.

현재 스포츠 치의학은 두가지 방면으로 연구가 진행되고 있는데, 하나는 부드러운 재질로 만든 마우스 가드로 스포츠 외상의 예에 관한 연구이고, 또 하나는 딱딱한 재질로 만든 교합안정장치로, 구강 기능과 전신의 운동능력과 의 상관성에 관한 연구이다. 현재 많은 프로선수들이 운동능력향상을 위해 교합안정장치를 사용해 오고 있다. 그러나 국내에서는 스포츠 치의학에 대한 관심이 적어 위와 같은 연구가 이루어져 있지 않을 뿐만 아니라 그러한 연구를 위한 기초 자료조차도 준비되어 있지 않은 실정이다. 또한 소수의 연구에서 실험 대상자의 정확한 분석과 교합 안정장치 장착 전과 후의 변화를 보여주지 못하고 있다. 이에 저자는 골프선수들의 교합분석과 턱관절분석을 시행하고, 피검자의 상태에 따른 정확한 교합안정장치를 제작하여 장치 장착 전과 후의 저작근의 근활성량의 변화와 드라이버 비거리의 변화를 측정하여 분석하였다. 그 결과 교합안정장치를 장착함으로써 저작근의 근안정이 유도되고, 드라이버 비거리가 증가되었다. 특히 측두하악장애를 지닌 골프선수일수록 교합균형장치를 사용함으로 드라이버 비거리의 향상에 도움이 될 것이라고 기대된다.

Purpose: This study intends to set standard for organizing the curriculum of short-term dental technicians and the change of job environment, as well as the knowledge & training, by identifying the importance and actual job performance of dental technicians following job analysis in the university education of Dept. of Dental Laboratory Technology, and furthermore to foster junior executives to cope with modernization and globalization. Methods: The tools used in this study are based on the job analysis of research report suggested by National Health Personnel Licensing Examination Board(Lee Gyu-seon, 2011), and it consists of general characteristic 7 items. Every competence duty was measured through Likert 5 point gauging, and internal consistency through Cronbach's Alpha. The competence importance of entire questionnaire was .984 and its performance was .874, reflecting considerably high level, and in terms of each competence duty, high credibility was proved and high internal consistency was verified with competence importance ranging from the minimum .655 to the maximum .966 and its performance ranging from the minimum .677 to the maximum .993. Results: Competence importance and its performance in each duty on the job analysis of dental technicians were measured. In competence importance in each duty, the highest was "checking design order form"(average, 4.52), followed by "selling dental prosthesis"(average 4.49), "making removable orthodontic appliance"(average, 4.48), "open managing dental laboratory"(average, 4.46) in order. However, "making complete denture" was found the lowest(average, 4.23), with importance of all competence dutys was considerably high level. In the performance of its competence duty, "checking design order form"(average, 4.04) was found to be the most importance competence, followed by "making conservative restoration"(average, 4.00), "making porcelain"(average 3.98), "checking working cast"(average, 3.90) in order. However it was found out that "making fixed orthodontic appliance"(average, 3.12) was the lowest, and the importance of all competence dutys was quite high level. Conclusion: The duties of dental technicians consist of 13 kinds, in total, and it was found out that "checking design order form"(average, 4.52) was the most important in the competence importance and job performance. In particular, it was revealed that there was a great difference between the competence importance and its performance in the order of "selling dental prosthesis", "open managing dental laboratory", "making removable orthodontic appliance", "making CAD/CAM prosthesis", and then "making fixed orthodontic appliance".

The aim of this document is to evaluate the effect of bite balance on physical fitness and motor capacity to determine the importance of the occlusal stability as a possible action mechanism of occlusal appliance including mouthguards on physical performances. We all remember that day when the prominent athlete was in the news wearing a mouthguard to improve human athletic performance. I once had investigated the determinants of athletic performance in all sorts of sports. Most of the studies had overinterpretation of results and lack of evidence to support the information. However, I discovered great expectations for new possibility in this field and settled for a more academic approach to this intriguing subject. The followings are some examples of the subject 1. Archers who wore occlusal appliances to increase the vertical dimension of occlusion by 2~3mm increased their ability to focus and to maintain good sense of balance. Their accuracy rate has been improved. The appliance was made of acrylic resin (a type of plastic). 2. Canoe players who wore occlusal appliances to increase the vertical dimension of occlusion by 5mm surpassed longtime competitor and won the race with 10 seconds gap. 3. A cycle rider who wore an occlusal appliance to treat his malocclusion surpassed his old record from 10.8 seconds to 10.3 seconds. His muscle reflexes (anaerobic exercise) and endurance (aerobic exercise) has been enhanced. 4. Occlusal appliances had a good effect on athletic performance in most sports such as swimming, diving, and weightlifting. As for the clenching on dentition, people clench their teeth when they push their physical and mental limits during sports activities. Clenching can be induced by physical exertion when maximum muscle strength is retained and this is similarly found in different types of exercises. In addition, restraint of respiratory function is observed. Therefore, creating a occlusal balance with occlusal appliance or mouthguard promoted a favorable influence when an athlete clenches.

Background: This study aimed to evaluate the effect of a prefabricated functional appliance (Myobrace^®) on skeletal, dental, and soft tissue components in children with Class II, division 1 malocclusion. Methods: Thirteen patients with Class II, division 1 malocclusion (9 girls and 4 boys; mean age, 8.2±0.9 years at the start and 9.3±1.0 years at the end of the treatment) were treated with Myobrace^® for a mean period of 12.9±4.0 months. Patients were instructed to use the appliance daily for 1 hour and overnight while sleeping. A control group of 10 patients with untreated Class II, division 1 malocclusion (3 girls and 7 boys; mean age, 9.0±1.6 years at the start and 10.4±2.1 years at the end of the observation) was included to eliminate possible growth effects. The mean observation period for this group was 17.7±11.2 months. Lateral cephalograms were taken at the start and end of the treatment, and findings from 41 measurements were analyzed using the V-Ceph^TM program. The mean and standard deviation of cephalometric measurements were analyzed using paired and independent sample t-tests. Results: The treatment group showed significant changes in SNB, ANB, maxillary protrusion, ramus height, proclination of upper anterior teeth, interincisal angle, overjet, and upper lip protrusion compared with the control group. However, only decrease in ANB, maxillary protrusion, overjet, upper lip protrusion, and increase in interincisal angle were significantly higher in the treatment group than in the control group. Conclusion: The prefabricated functional appliance induced skeletal, dentoalveolar, and soft tissue changes, resulting in a significant reduction in anteroposterior discrepancy.

Clinicians generally agree that Class III malocclusion is one of the most difficult to treat. When the Class III malocclusion is characterized by maxillary retrusion in growing patients, the use of a face mask may be the treatment of choice. Although face mask can achieve excellent orthopedic effects. It demands special patient compliance because it is worn extraorally and is not as esthetic or comfortable as intraoral appliance. This report presents the clinical cases of mandibular protrusion correction in growing patients, who were treated by TTBA(Tandem Traction Bow Appliance) that's a intraoral appliance.

Patients who have impacted tooth are found commonly in orthodontic treatment. Although it is difficult to find the cause of impacted teeth, the most common, causes are prolonged retention of the deciduous teeth, trauma, aberrant sequence of eruption, lack of space and deficiency of Vitamin D. Impacted teeth may lead to esthetic and functional problems and root resorption of adjacent teeth, so we should treat it as soon as possible. Commonly used treatment method is the following: After surgically uncovering of the impacted teeth, a bond of orthodontic appliance is established, and orthodontic traction is started with a removable or fixed appliance. We used the modified lingual arch with a soldered auxiliary appliance in lingual arch for traction of lower impacted teeth. The modified lingual arch could control the magnitude and direction of the applied force with one-arch treatment, and also could give continuous force to impacted tooth without patient patient cooperation. We achieved good results with the modified lingual arch.
