The factors influencing the relapse and recurrence of skeletal deformity after the orthognathic surgery include various factors such as condylar deviation, the amount of mandibular set-back, stretching force by the soft tissues and muscles around the facial skeleton. The purpose of this report is to recognize and analyze the possible factors of reoperation after orthognathic surgery, due to early relapses. Six patients underwent reoperation after the orthognathic surgeries out of 110 patients from 2006 to 2009 were included in this study. In most cases, clincal signs of the insufficient occlusal stability, anterior open bite, and unilateral shifting of the mandible were founded within 2 weeks postoperatively. Although elastic traction was initiated in every case, inadequate correction made reoperation for these cases inevitable. The chief complaints of five cases were the protruded mandible combined with some degree of asymmetric face and in the other one case, it was asymmetric face only. Various factors were considered as a major cause of post-operative instability such as condylar sagging, counter-clockwise rotation of the mandibular segment, soft tissue tension related with asymmetrical mandibular set-back, preoperatively existing temporomandibular disorder (TMD), poor fabrication of the final wafer, and dual bite tendency of the patients.

Botulinum toxin (BT) was the first toxin to be used in the history of human medicine. Among the eight known serotypes of this toxin, those currently used in medicine are types A and B. This review article mainly discusses BT type A (BTA) because it is usually used in dentistry including dental anesthesiology and oral and maxillofacial surgery. BTA has been used mainly in the treatment of temporomandibular joint disorder (TMD) and hypertrophy and hyperactivity of the masticatory muscles, along with being a therapeutic option to relieve pain and help in functional recovery from dental and oral and maxillofacial surgery. However, it is currently used broadly for cosmetic purposes such as reducing facial wrinkles and asymmetry. Although the therapeutic effect of BTA is temporary and relatively safe, it is essential to have knowledge about related anatomy, as well as the systemic and local adverse effects of medications that are applied to the face.

Trismus is a common problem to most people experiencing at once in his or her life and to most dental practitioners experiencing frequently. It has a number of potential causes which are single factor or complex factors. Its treatment will depend on the cause. The purpose of this study was to discuss the causes of trismus condition and the various treatments available. This study was made by reviewing of collected data from 86 patients complained of trismus among patients who were diagnosed by TMD, tumor, infection including tetanus, soft tissue anomalies, bony fracture and ankylosis from Jan 2002 to Dec 2004 on department of oral and maxillofacial surgery at Pusan National University Hospital, South Korea. The clinical reviews regarding chief complaints, clinical characteristics, diagnostic examination, treatments and the results on the patients were given as follows. 1. The etiology of trismus commonly were derived from temporomandibular joint(TMJ) disorder, TMJ ankylosis, TMJ tumor, odontogenic maxillofacial infection, mandibular condylar fracture, tetanus. 2. The chief complaints of trismus patients were progressive mouth opening limitation, TMJ pain, malocclusion, facial asymmetry, retrognathic state. 3. Especially, for the differential diagnosis between the fibrous ankylosis and true bony ankylosis, computed tomogram (CT) was useful. Surgical gap arthroplasty on bony ankylosis patients was applied and the gain of mouth opening after operation was average 35.8 mm during 19 months. 4. The tetanus, rarely, also induced the trismus with the range of mouth opening less than 10 mm. The average serum level of tetanus anti-toxin was 0.02-0.04 IU/mL. The limitation of mouth opening was improved into average 38 mm on 4 weeks after injection of 10,000 units of tetanus immune globulin. 5. In the treatment of osteochondroma, TMD, odontogenic infection and fracture, and the others inducing trismus, to obtian the maximum result and decreased inadequate time and effort, it is important to finding the causes from the exact clinical examination and diagnosis.

The purpose of this study was to estimate primary diagnosis, prediction of prognosis and recognition fo treatment progress for treatment of TMD patients through measuring the various ranges of mandibular movement in normal and TMDs patients using Mandibular Kinesiograph K-6 Diagnostic system. In normal groups, 20 adults were selected, who have normal or class I molar relationship, and have no symptoms on TMJ and masticatory muscles, and have restorations less than 3 surfaces on each tooth, and have no other prosthetic restoration. In Patients group, we selected 31 outpatients who were confirmed to TMDs with clinical examination and radiographic findings. The obtained results were as follows : 1. In maximal opening, patient group was showed the limitation of vertical movement range (P<0.01) and lager lateral deviation than in normal group (P<0.05). And actual dimensional displacement of opening was calculated larger in normal group (P<0.05). 2. In protrusive movement, patients group was showed the limitation of anteroposterior movement range (P<0.001) and larger deviation than in normal group (P<0.01). And actual 3 dimensional displacement of protrusion was calculated larger in normal group (P<0.001). 3. In lateral maximum excursion, compared with normal group patient group was no significant differences to affected side, but was showed the limitation of lateral movement to unaffected side (P<0.001). 4. There was no significant difference in movement velocity of opening and closing in both groups. 5. Mandibular movement from physiologic rest position to centric occlusion was moved more anteroposteriorly in patient group. 6. Mandibular movement from centric relation to centric occlusion was no significant difference in both groups.

Background: Emergencies in dentistry can be classified as medical and dental. Medical emergencies occur mainly during dental treatment in patients with a systemic disease. Dental emergency departments are largely divided into dental emergency rooms located in dental college hospitals and medical emergency rooms located in medical institutions. This study aimed to analyze the characteristics of and provide help to dental emergency patients in a dental hospital. Methods: Overall, 1806 patients admitted to a dental emergency room at Yonsei University Dental Hospital for 1 year were included. The data collection period was from October 1, 2014 to September 30, 2015. An investigator reviewed medical records from the electronic medical record (EMR) system and radiographs. Results: The patients were 1,070 men and 736 women. The sex ratio was 1.45:1. The commonest age group was of 0-9 years, including 451 (25.0%) patients, followed by 20-29 years, including 353 (19.5%) patients, and 30-39 years, including 277 (15.3%) patients. Of the 108 patients transferred to the Severance emergency department, 81 had trauma, 19 were in pain, 4 were bleeding, and 4 had other complaints. Among chief complaints, 1,079 patients (60.3%) had trauma, 564 (31.5%) had pain, and 75 (4.2%) had bleeding. Twenty-three cases (1.3%) were caused by temporomandibular disorder (TMD). Conclusion: Dentists should be able to adequately assess patients in a dental emergency room and treat trauma, pain, and bleeding.

Purpose: Disc displacement can cause resorption of the head of the condyle and affect its volume. This study analysed the volume of normal condyles and those with disc displacement with reduction (DDR) in cone-beam computed tomography (CBCT) scans from the Indonesian population. Materials and Methods: This study analysed 56 condyles (26 normal and 30 with DDR) from patients who visited the Oral and Maxillofacial Radiology Unit after being referred from the Prosthodontics Unit at Dental Hospital Universitas Padjadjaran from December 2020 to February 2021. Samples were divided into 2 groups (normal and DDR left and right-side condyles) based on the DC/TMD Axis 1 form through the clinical examination results. Both sample groups were exposed to CBCT radiation. The CBCT imaging results in the Digital Imaging and Communications in Medicine format were exported to the open-source ITK-SNAP format to determine condyle volume. Volumetric data from the cortical and trabecular areas of the right or left side condyles were arranged by sex. The independent t-test was used to determine the significance of differences with IBM SPSS version 21.0. Intra- and inter-observer reliability and validity were tested before determining the volume of the condyles. Results: Normal condyles and DDR condyles showed significant differences in volume (P<0.05). Significant differences were also seen in cortical (P=0.0007) and trabecular (P=0.0045) volumes. There was a significant difference in condylar volume based on sex. Conclusion: The normal condyle volume was significantly different from the DDR condyle volume in both sexes.

측두하악관절장애는 저작근, 측두하악관절, 주변 구조물 또는 모두를 포함하는 다수의 임상문제를 포함하는 용어이다. 근막동통은 측두하악관절장애 중 저작근 장애의 한 종류로, 근막 발통점에 의해 발생하는 감각, 운동, 자율신경 증상이다. 측두하악관절장애와 근막동통의 원인에 대한 논쟁이 지속되어왔다. 특히 교합 원인은 오랫동안 논쟁의 핵심이었으며, 많은 노력에도 불구하고 교합원인에 대한 연구는 상반된 결과를 보였다. 이런 논쟁은 대부분이 측두하악관절장애 본연의 복잡성에서 기인하지만, 부적절하고 부적당한 연구설계, 선정기준, 연구방법 또한 중요한 역할을 한다. 최근에 교합분석시 시간과 상대적 힘이 측정가능한 컴퓨터 교합분석 기기인 T-Scan II가 소개되었다. 일부 저자들은 T-Scan II를 이용하여 이개시간 개념 및 연장된 구치부 이개시간과 근막통증의 연관성에 대하여 제안하였다. 그러나 T-Scan II를 이용한 기존의 연구들은 근막통증에 대한 정확한 진단 기준을 제시하지 못하였으며, 대조군과의 비교 부재 및 다른 많은 문제점을 가지고 있었기 때문에 신뢰할 만하지 못하다. 이번 연구의 목적은 컴퓨터 교합분석 기기인 T-Scan II을 이용하여 30명의 실험군을 선택하고 이를 38명의 대조군과 비교함으로써, 근막통증과 구치부 이개시간과의 연관성을 평가하는 것이다. 통계적으로 분석된 결과는 다음과 같다: 1. 반복 측정한 이개시간의 Cronbach ${\alpha}$ 계수는 0.92 였다. 2. 반복 측정한 이개시간 평가시 양측에서 실험군과 대조군 사이 유의성 있는 차이를 보이지 않았다. 3. 이개시간 평가시 좌측 우측 사이에 유의성 있는 차이를 보이지 않았다. 이상의 결과로부터 근막통증과 이개시간 사이에는 관련성이 없는 것으로 판단된다. 따라서 근막통증을 치료하기 위하여 이개시간을 줄이는 비가역적인 치료는 적절치 않다. 향후의 연구에 있어서, 여러 교합요소와 헬키모 지수 등을 이용하여 증상의 정량화를 고려한 보다 통제된 대규모 환자 집단에 대한 연구가 필요할 것으로 사료된다.

측두하악장애 환자 중 하악과두의 퇴행성 골 변화를 보이는 환자의 분포와 임상적 특징을 규명하고자 측두하악장애로 진단받은 6,070명의 환자들을 대상으로 연구를 시행하였다. 환자들의 초진 시 파노라마와 TMJ 파노라마 사진을 관찰하여 하악과두의 퇴행성 골 변화 유무를 기준으로 환자들을 퇴행성 골 변화를 보이는 군(DJD군)과 골 변화를 보이지 않는 군(non-DJD군)으로 나누고, 환자들의 초진 의무기록을 바탕으로 두 군 간의 특징을 비교, 분석하였으며, 각종 변수들이 DJD 발병에 미치는 상대적 위험성을 측정하기 위하여 로지스틱 회귀분석을 시행하였다. 연구결과 전체 환자 중 DJD군에 속한 환자는 31.7%였고, non-DJD군에 속하는 환자는 68.3%였다. DJD군은 성별에 따라 다른 분포를 보여 남자보다 여자의 이환율이 높았고, 10대와 20대에서 가장 높은 분포를 보였다. 환자의 내원 주소 중에서는 전치부 개방교합, 턱의 후퇴감, 안모 비대칭, 개구장애를 주소로 내원한 환자가 다른 주소로 내원한 환자들에 비해 DJD를 보일 위험성이 높았으며, 교정치료 경력이나 중심 위-중심교합위 변위 그리고 염발음을 보이는 환자도 DJD군에 속할 위험성이 큰 것으로 나타났다. 따라서 측두하악장애를 가진 환자 중 30세 이하의 여성이 위와 같은 임상적 특징을 보이는 경우, 교정치료를 계획할 때 DJD에 이환 되었을 가능성에 대하여 충분히 주의를 기울여야 할 것으로 생각된다.
