Purpose: This article examined the affecting factors of a malocclusion status of a patient for orthodontic treatment, orthodontics medical expenses and oral health behavior on orthodontic satisfaction. Methods: This paper conducted a survey from the 15th of July to 30th of September 2012 for the patients who were under orthodontic treatment at three dental clinics where are in Deagu, and distributed a total of 210 questionnaires and analyzed 194 questionnaires, excepting for some questionnaires that were answered unfaithfully. Results: This study classified the related factors into a feeling of satisfaction with treatment and mental satisfaction for finding orthodontic satisfaction. There were the effect of the right tooth-brushing method, a periodic scaling and orthodontics medical expenses on a feeling of satisfaction with treatment, and power of explanation was 16.7%. Conclusion: There were the effect of a malocclusion status, matters that requires attention during orthodontic treatment, a periodic scaling during orthodontic treatment and orthodontics medical expenses on mental satisfaction, and power of explanation was 16.9%. Based on the result above, this paper concluded that preventive treatment and early treatment should be emphasized through developing a program for regular oral examination suited to each medical type, including the method for improving the medical treatment condition and care service for increasing orthodontic satisfaction, which the dental medical-service providers could consider the patients and secure trust.

In orthodontics and orthognathic surgery. cephalogram has been routine practice in diagnosis and treatment evaluation of craniofacial deformity. But its inherent distortion of actual length and angles during projecting three dimensional object to two dimensional plane might cause errors in quantitative analysis of shape and size. Therefore, it is desirable that three dimensional object is diagnosed and evaluated three dimensionally and three dimensional CT image is best for three dimensional analysis. Development of clinic necessitates evaluation of result of treatment and comparison before and after surgery. It is desirable that patient that was diagnosed and planned by three dimensional computed tomography before surgery is evaluated by three dimensional computed tomography after surgery. too. But Because there is no standardized normal values in three dimension now and three dimensional Computed Tomography needs expensive equipments and because of its expenses and amount of exposure to radiation. limitations still remain to be solved in its application to routine practice. If postoperative three dimensional image is constructed by pre and postoperative lateral and postero-anterior cephalograms and preoperative three dimensional computed tomogram. pre and postoperative image will be compared and evaluated three dimensionally without three dimensional computed tomography after surgery and that will contribute to standardize normal values in three dimension. This study introduced new method that computer-simulated three dimensional image was constructed by preoperative three dimensional computed tomogram and pre and postoperative lateral and postero-anterior cephalograms. and for validation of new method. in four cases of dry skull that position of mandible was displaced and four patients of orthognathic surgery. computer-simulated three dimensional image and actual postoperative three dimensional image were compared. The results were as follows. 1. In four cases of dry skull that position of mandible was displaced. range of displacement between computer-simulated three dimensional images and actual postoperative three dimensional images in co-ordinates values was from -1.8 mm to 1.8 mm and 94％ in displacement of all co-ordinates values was from -1.0 mm to 1.0 mm and no significant difference between computer-simulated three dimensional images and actual postoperative three dimensional images was noticed(p>0.05). 2. In four cases of orthognathic surgery patients, range of displacement between computer­simulated three dimensional images and actual postoperative three dimensional images in coordinates values was from -6.7 mm to 7.7 mm and 90％ in displacement of all co-ordinates values was from -4.0 to 4.0 mm and no significant difference between computer-simulated three dimensional images and actual postoperative three dimensional images was noticed(p>0.05). Conclusively. computer-simulated three dimensional image was constructed by preoperative three dimensional computed tomogram and pre and postoperative lateral and postero-anterior cephalograms. Therefore. potentiality that can construct postoperative three dimensional image without three dimensional computed tomography after surgery was presented.

본 연구는 교정 진료를 받은 경험이 있는 교정이 완료된 환자의 대상으로 치열교정환자의 교정치료에 따른 진료인식이 교정치료를 하는데 만족과 추천에 미치는 영향을 조사하여 교정환자를 전문으로 하는 의료기관에 정보를 제공하고자 2010년 2월부터 8월까지 조사한 것으로 SAS ver. 9.1 분석결과 다음과 같은 결론을 얻었다. 1. 조사대상자의 치과의료기관 이용특성으로는 삐뚤어진 치아교정이 43.9%로 가장 많았으며, 교정치료예상기간으로는 1년 6개월~2년이 53.3%로 과반수 이상으로 나타났으며, 교정이 완료 후 경과시간은 23.5%인 6~12개월이 지난 환자들이 많았고, Angle의 부정교합으로는 I급이 63.4%로 가장 많았고, 임상적 부정교합으로는 42.4%인 총생이 가장 많았다. 2. 대상자의 치과진료 협조도와 진료서비스 만족도, 본 의원 추천도, 편의시설 만족도들의 상관분석 결과에서는 각각의 항목들 간에 모두 유의한 양의 상관관계가 나타났다. 3. 교정치료에 대한 진료인식에 있어서는 교정치료 장치의 불편이 79.3%로 대상자의 대부분이 인식하고 있었으며, 교정치료 중 불편사항에 대해서도 69.8%로가 인식하고 있으며, 61.6%가 예상한 만큼 교정치료비가 나왔으며, 교정치료 중 내원횟수가 72.8%가 적절했다고 나타났으며, 교정치료의 기간도 61.2%로가 적절하다고 나타났고, 교정치료 중 진료내용의 이해에서도 62.6%가 이해하는 것으로 나타났다. 4. 일반적 특성에 따른 교정치료에 대한 진료인식도 비교에서는 남자보다 여자가 교정치료 장치의 불편인식도(p<0.05), 교정치료 중 불편사항이(p<0.05) 높은 것으로 나타났다. 이에 교정환자는 교정치료 시작 전에서 교정치료를 하는 동안에 여러 가지 필요한 사항들은 미리 인식함으로써 좀 더 만족스럽고, 효율적으로 교정치료를 받을 수 있음은 물론이고, 지인들에게 의료기관을 추천할 것으로 사료된다.
