변연골 하방으로까지 파절선이 연장된 치아를 수복하기 위해 파절선의 노출 및 생물학적 폭경의 재확립을 위한 삭제형 골수술을 동반한 외과적 치관 연장술을 고려해 볼 수 있다. 그러나 이 술식은 특히 전치부에서 심미성을 훼손시킬 수 있다. 따라서 지지골과 치은을 희생시키지 않으면서 파절선을 치조와 하방에서 상방으로 위치 시킬 수 있는 교정적 정출술이 권장된다. 이 술식은 생물학적 폭경의 재확립과 더불어 수복물을 건전한 치아 구조에 위치할 수 있도록 해 준다. 또 다른 대안으로, 교정적 정출술 보다 방법이 간단하며 시간이 적게 소요되고 한번의 술식만으로 정출이 완료되는 외과적 정출술도 고려해 볼 수 있다. 외과적 정출술을 이용할 경우 구강내 교정 장치를 위치시키고 조정하기 위해 환자가 치과에 여러번 방문할 필요가 없다. 본 연구에서는 상악 중절치에서 치관-치근 파절이 발생한 경우 교정적 정출술 또는 외과적 정출술을 통한 다각적 방법을 병용함으로써 성공적으로 수복한 증례를 보고하고자 한다.

Objectives : Purpose of this research is to determined the general knowledge on oral health and the usage of oral hygiene products in the orthodontic patients and try to provide an appropriate oral hygiene products for the patients. Methods : Orthodontic patients who visited a dental clinic in Daejeon were selected and data from 352 patients were collected. Questionnaire based on survey was conducted from 1st of March to 30th in 2011 and all the data was analysed by using SPSS statistical program (VER 15.0). Frequency analysis, $x^2$ test, T-test and the amount of diurnal variance analysis (one-way ANOVA) were also used. After that, scheffe's post-test method was conducted. Results : According to the general characteristics of oral health care knowledge score was $2.87{\pm}0.60$, the attitude score was $2.96{\pm}0.57$. toothbrush replacement cycle were less than 3 months (p=0.007, p=0.000) and frequency of brushing one day more than three times higher in patients with knowledge to help attitude. according to the sex, age, and duration of orthodontic treatment with oral hygiene devices of usage was higher in the calibration toothbrush usage, awareness was higher in the interdental toothbrushes. according to the type of orthodontic devices from the oral hygiene devices usage, removable group was the orthodontic toothbrush and electric toothbrush group were highest in the 'unknown', the fixed group was orthodontic toothbrush(67.3%) and electric toothbrushes(40.8%) was higher in the usage. Patients who used oral hygiene devices such as orthodontic tooth brush, interdental brush, electric toothbrush, water pik and fern solution showed wider knowledge on oral health care and oral hygiene devices compared to patients who answered as does not aware of oral hygiene devices and never used these products before. Conclusions : Orthodontic patient's oral health attitudes, knowledge, and oral hygiene devices usage are the general characteristics of the highest in the orthodontic toothbrush usage, awareness was higher in the interdental brush. Water pik and fern solution, rubber and gingival interdental stimulator turned massage does not use or low. Based on results from research, overall orthodontic patients who visited a dental clinic had low awareness and usage of oral hygiene devices. Therefore, it is required to educate general publics and the orthodontic patients and also promote the importance of usage of oral hygiene devices.

A conservative treatment approach to temporomandibular disorder (TMD) is recommended as the first line of management, usually with a stabilization splint. Recently, computer-aided design/computer-aided manufacturing and three-dimensional printer has been widely used in the dentistry since several years ago. The authors apply digital dentistry in oral medicine fields to make stabilization splint for TMD treatment.

본 연구는 치열교정치료를 받는 환자를 대상으로 치료 만족도 영향 요인을 조사하여 기대하는 치료만족도와 심리적 만족상태에 관하여 연구하고 진료서비스 향상을 위한 정보를 제공하고자 2009년 1월 20일부터 2월 28일까지 치열교정치료를 전문으로 하는 경기도 S치과의원, 대구광역시 B치과의원, 부산광역시 Y치과의원에서 치료 중인 382명의 환자와 보호자를 대상으로 구조화된 설문지를 이용한 직접면담조사를 실시하였다. 수집된 자료는 SPSS WIN 17.0K를 이용하여 분석하여 다음과 같은 결론을 얻었다. 1. 심미적(미용) 요인에 따른 교정치료의 만족도는 심미적 건강상태가 나쁜 집단이 4.07점으로 건강상태가 좋은 집단보다 높았으며(p<0.05), 치아배열 요인에 따라서도 건강상태가 좋은 경우가 4.04점으로 나쁜 경우의 3.93점보다 만족도가 높은 것으로 나타났다(p<0.05). 2. 교정치료의 필요성에 따른 만족도는 필요성을 많이 인식하고, 진료 내용의 이해도 많은 경우, 교정치료 진행 과정의 적응을 잘하고 있는 경우에 만족도가 높았으며, 교정 치료 후 심리적 변화는 긍정적으로 변한 경우 만족도가 높았다(p<0.001). 3. 교정치료 만족도에 영향을 미치는 요인은 교정치료의 필요성(p<0.001), 교정치료 진행 과정 적응(p<0.001), 교정 치료 후 심리적 변화(p<0.01), 교정치료 후 치아 건강 기대정도(p<0.01), 진료 내용에 대한 이해(p<0.01)의 순으로 유의한 영향을 미치고 있었다. 이러한 연구결과로 치열교정환자의 교정치료의 만족도는 비교적 높은 것으로 나타나므로 환자의 정신심리상태를 파악하여 진료의 질적인 부분과 환자의 기대부분에 세심한 배려가 필요할 것으로 사료된다.

One of the most common oral surgical procedures is the extraction of the lower third molar (LTM). Postoperative complications such as paresthesia due to inferior alveolar nerve (IAN) injury are commonly observed in cases of horizontal and vertical impaction. The present report discusses a case of a vertically impacted LTM associated with a dentigerous cyst. An intimate contact between the LTM roots and the mandibular canal was observed on a panoramic radiograph and confirmed with cone-beam computed tomographic (CBCT) cross-sectional cuts. An orthodontic miniscrew was then used to extrude the LTM prior to its surgical removal in order to avoid the risk of inferior alveolar nerve injury. CBCT imaging follow-up confirmed the success of the LTM orthodontic extrusion.

Impacted or unerupted permanent teeth have many problems in making a diagnosis and treatment plan in dental clinic. There are several methods to treat impacted teeth. The combination of surgical exposure and orthodontic traction is usually the treatment of choice in cases with impacted teeth. Two cases are reported, which were treated with surgical intervention and orthodontic movement. and one case is treated with orthodontic movement alone. To improve esthetic problem and maintain periodontal health, We should avoid loss of attached gingiva in surgical exposure, and excessive orthodontic force during the traction of the impacted tooth.

Purpose: By investigating oral health knowledge and oral health behavior of orthodontic patients, we intend to identify factors that affect their satisfaction with orthodontic treatment and use them as fundamental data for improving the satisfaction of orthodontic patients. Methods: Busan from February 1st to March 31st, 2021. Dental disease in Gyeongsangnam-do. A self-contained survey was conducted on patients undergoing orthodontic treatment in the clinic. A total of 185 copies were analyzed. Using the lBM SPSS Statistics 21 program, multiple regression analysis was conducted by setting oral health knowledge and oral health behavior as independent variables to determine factors affecting remedial treatment satisfaction. Results: The satisfaction level of orthodontic treatment was 1.53 points higher than 'understanding the cost of orthodontic treatment' and 'smooth relationship with related staff while receiving orthodontic treatment' was low at 1.23. The average calibration satisfaction was 1.34. Factors affecting remedial treatment satisfaction were shown in the order of oral health behavior (p<0.000), educational experience (p<0.010), gender (p<0.015) and oral health knowledge (p<0.020). Conclusions: Through the above results, it is necessary to develop programs to improve oral health knowledge through customized individual oral health education by enhancing individual oral health behaviors of individuals.

병적 치아 이동된 상악 전치를 가진 중등도 치주염 환자에서는 치태 관리를 통한 치주 염증의 해소뿐만 아니라 치아를 재위치 시키기 위한 교정치료가 함께 필요하다. 이 때의 교정치료는 더 적은 힘의 적용과 치아의 저항중심, 최적의 힘 등을 세심하게 고려해야 하는데, 이동하고자 하는 치아에만 적용되는 분절호선은 이동의 예측성을 높여주고, 힘을 조절할 수 있어 보다 효율적이다. 또한 교정치료 시, 고정원으로 사용되는 치아의 원치 않는 움직임을 차단하여 구치 교합 상태를 유지할 수 있는 장치 설계가 필요하며, 이를 위해 다양한 종류의 골성 고정원이 사용될 수 있다. 본 증례에서는 정출되고 변위된 상악 전치를 가진 환자에서, 철저한 치주 치료와 적절한 힘과 역학이 설계된 교정 장치로, 양호한 치료 결과를 얻을 수 있었으므로, 소개하고자 한다.

The aim of this study was to evaluate the amount and interrelationship of the soft and hard tissue changes after simultaneous maxillary clockwise rotation and mandibular setback surgery in skeletal class III malocclusion. The sample comprised of 16 adult patients who had anteroposterior skeletal discrepancy. These patients had received presurgical orthodontic treatment and surgical treatment which consisted of Le fort I Osteotomy and bilateral saggital split ramus osteotomy. The presurgical (T1) and postsurgical (T2) lateral cephalograms were evaluated. The computerized statistical analysis was carried out with SPSS/PC program. The results demonstrated a decrease in the vertical dimension in the soft and hard tissue. The nasolabial angle was increased and the mentolabial angle was decreased. The results showed also many statistically significant correlations(p<0.05). The lower lip closely followed the skeletal movement of the B- point in the horizontal plane. The double jaw rotation surgery can afford a good solution to solve the problems of class III malocclusion cases.
