Objective: Many factors are considered when a patient chooses the type of dental institution they wish to receive treatment from. Numerous studies have been conducted regarding this issue. However, more research is needed in analyzing the patient's psychological aspects when he/she decides to choose the dental institution they wish to receive treatment from. Methods: A locus of control test was utilized to analyze the psychological aspects in orthodontic patients of a university dental hospital and a private dental clinic. The locus of control test is known to be useful in predicting a human being's behavior. Both intrinsic and extrinsic locus of control tests were carried out in 934 orthodontic patients attending Seoul National University Dental Hospital and 1466 orthodontic patients from a private dental clinic. Results: The orthodontic patients at the university dental hospital showed a stronger extrinsic locus of control compared with those from the private dental clinic. Conclusion: The orthodontic patients at the university dental hospital value the doctor as the authority figure and the treatment quality more than those at the private dental clinic.

Skeletal Class III malocclusion is a relatively common form of malocclusion in Korea. In borderline cases where only mild skeletal discrepancy exists and if worsening of the facial profile is expected as a result of premolar extraction, mandibular full arch distalization with miniscrews is the treatment of choice. The purpose of this study was to investigate the pattern of tooth movement and evaluate the stability of mandibular full arch distalization and to identify correlation between stability and factors such as initial skeletal pattern, dental changes during treatment and alveolar bone in symphysis region using lateral cephalograms.

In evaluation of some area within the craniofacial complex posteroanterior cephalogram together with lateral cephalogram is used for assessment of the exact existence and posture by grasping 3-dimensional concept. The usages of posteroanterior cephalogram in orthodontics are following; 1. The use during diagnosis and treatment planning 1) Assessment of the area and amount of facial asymmetry. 2) Assessment of therapeutic position for diagnosis and treatment 2. The Assessment of success in orthodontic mechanics If we use posteroanterior cephalogram together with lateral cephalogram adequately and simultaneously we can establish the exact diagnosis and appropriate treatment planning.

Etiologies of the molar teeth impaction are cyst, supernumerary teeth, ankylosis by replacement resorption, abnormal eruptive path, improper orthodontic treatment, etc. If the impacted teeth were untreated, the sequallae was as follows : loss of occlusal function, loss of permanent tooth, extrusion of opposite tooth, root resolution of adjacent teeth. The most important factor of solution of impacted teeth is treatment timing & proper application of orthodontic forces.

저자는 현재 Light-Wire Technique에서 많이 사용되는 0.016" 및 0.018"의 원형 녹색 "Elgiloy" 교정용 탄선의 Residual Stress가 열처리에 의하여 제거되는 양을 Testing Jig를 사용하여 측정하였다. 그 결과는 다음과 같다. 1. 0.016" 및 0.018"의 원형 녹색 "Elgiloy" 교정용 탄선은 열처리 시 온도의 증가에 따라 제거되는 Residual stress의 양도 증가한다. 2. 동일 온도조건에서 시간조건의 변화에 따른 Residual Stress의 제거치는 차이는 있었으나 현저하다고 인정할 수 없다. 3. 통상적 열처리 방법에 의하면 제거된 Residual Stress의 양은 0.016"인 경우 $26.95\%\~38.54\%$, 0.018"인 경우 $27.06\%\~41.05\%$이다. 4. $950^{\circ}F$에서 열처리했을 시 제거된 Residual Stress의 양은 0.016"인 경우 $38.54\%\~43.16\%$, 0.018"인 경우 $41.05\%\~44.56\%$이다.

Etiologies and traditional treatment modalities regarding anterior open-bite were discussed to elucidate the advantages and disadvantages. And an emphasis was placed on the understanding of the true nature of anterior open-bite. Most anterior open-bite malocclusions can be treated with a high degree of sucess and stability without surgical intervention with the congnizance of the anatomy, the physiology and the dynamics of orthodontic mechanotherapy. In this regard, a Multiloop Edgewise Arch Wire (MEAW) Technic, which has been developed during the past twenty years by Dr. Kim, was introduced. Three cases with anterior open-bite malocclusion were presented to demonstrate the mechanotherapy.

This study was designed to get the Knowledges of the dental arch shapes of Koreans. The subjects consisted of 101 individuals with normal occlusion. The results were as follows, 1 Author found the ideal arch shape of normal occlusion 2 The regression curve and equations of normal occlusion were obtained from SPSS 3 Ideal arch form and superimposition form were obtained by Versa-cad.
