  • Cerebrovascular Accident(stroke) is that a sudden, nonconvulsive loss of neurologic function due to an ischemic or hemorrhagic intracranial vascular event. If stroke happens at the portion of trigeminal motor nucleus or its control part of cerebral cortex, masticatory muscles will be atrophy or paralyzed. So it is possible that dental occlusion changes after stroke. A 74-aged woman recurred mild stroke 2 month ago, who had experienced severe stroke 2 years ago. After recurrence, suddenly her upper full denture was dropped when lower denture contacted upper one. According to the her occlusion exam, her lower jaw moved back slightly compared with the occlusion of old denture. And her face had asymmetry and lower jaw dislocated to paralyzed side. A 50-aged man was treated because many cervical caries, which would occur because of an aftereffect of stroke, long-herm hospitalization and limits of self oral-care. 6 years ago he had cerebral hemorrhage and he claimed that he cannot bite exactly. Just two pairs of teeth was contact on biting, his lower jaw was located back, too. This two case suggests that dental occlusion can change after stroke.

  • The relationship between dental occlusion to temporomandibular Joint (TMJ), systemic symptoms and health has been discussed and theoretical reasons have been the foundation for treatments performed by various areas of alternative treatments. It has been noted that there have been increase in the available methods and treatments for the general public regarding these areas of treatment modality. Korean Academy of Stomatognathic function and Occlusion have carried out literature review of five of those treatment theories available; they are Craniosacral mechanism, Osteopathy, Myodontics, Chirodontics, Dental distress syndrome and Quadrant theorem. Each of these modalities will be introduced and brief summary of their efficacy and efficiency will be discussed.

  • The purpose of this study was (1) to determine the prevalence of some causes by which dental occlusion might be affected , (2) to determine the prevalence of malocclusion, and types of molar, vertical incisor and horizontal incisor relationships, and (3) to examine the sex difference in the prevalence ratios, and (4) to determine the between-examiner differences in assessing types of dental occlusion. The material consisted of 1281 males and 811 females, total 2091 persons, aged 17 to 21 years. Two examiners who were graduate students in the orthodontic course, examined independently dental occlusion of the material. Before calculating the statistics, the subjects consisted of 156 mates and 164 females, total 320 persons, haying any one or more causes suspected to affect dental occlusion, was eliminated. Then the remained subjects, 1124 males and 647 females, total 1771 persons, were assessed. The results were as follows 1. The prevalence of some causes by which dental occlusion might be affected was 15.32 per cent. The missing rate of any one or more first molars was 8.85 percent, that of any one or more teeth positioned anterior to the first molar was 3.83 per cent. The prevalence of crossbite of the first molar was 0.48 per cent, that of retained primary teeth was 0.77 percent, and that of orthodontic treatment was 0.43 per cent. 8. The rate of between-examiner difference was 12.53 per cent in assessing the types of molar relationship, 18.86 percent in assessing the types of horizontal incisor relationship, and 26.37 percent in assessing the types of horizontal incisor relationship. 3. There was no sex difference in the prevalence ratios of the types of molar relationship. The prevalence of Class I molar relationship was 80.91 percent, that of Class II was 5,03, that of Class II subdivision was 4.01, Percent, that of Class III was 5.99 percent and that of Class III subdivision was 4.07 percent. 4. In the prevalence of the types of horizontal incisor relationship, there were no sex differences except that of Class II division 2. The prevalence of Class I horizontal incisor relationship was 73.12 percent, that of Class II division t was 12.03 percent, that of Class II division 2 was 6.58 percent in male and 4.33 percent in female, and that of Class III was 9.09 percent. 5. In the prevalence of the types of vertical incisor relationship, there were no sex differences except that of deep bite, The prevalence of open bite was 2.20 per cent, that of edge-to-edge bite was 9.15 percent, that of normal bite was 76,34 percent, and that of deep bite was 14.15 percent in male and 9.12 percent in female. 6. There was no sex difference in the prevalence of malocclusion the prevalence of malocclusion was 82.67 percent and that of normal occlusion was 17.33 percent. 7. There was a tendency that when Class I molar relationship changed to Class II, incisor relationships were to be larger overjet or upright upper incisors and deep bite, but when that changed to Class III molar relationship, these were to be cross bite and openbite.

  • Various conditions such as pain or effusion of temporomandibular joint, degenerative condylar resorption, and articular disc displacement can be a cause of malocclusion. However, the reasons of occlusal changes are ambiguous in some patients. Unexpected occlusal change in patients with or without temporomandibular disorder (TMD) symptom was mostly caused by masticatory muscular disorders. This article reports two cases of recovery of occlusal relationship in TMDs patients after stabilization splint therapy. Stabilization splint therapy could be useful in certain conditions of occlusal changes in TMD.

  • This study was undertaken to document relations between facial skeletal pattern and dental occlusion. The data in .this study were collected from pretreatment cephalometric radiographs and study models of patients' records present in the files of Orthodontic Department, Seoul National University Hospital. Patients were selected on the basis of a mandibular plane-sella nasion angle equal to or greater than $38^{\circ}$ (high SN-MP angle) or equal to or less than $26^{\circ}$ (low SN-MP angle). Patients in the mixed dentition and with missing permanent teeth were excluded for ease of assessing tooth size / arch circumference relationships and then 30 high SN-MP and 11 low SN-MP patients were selected among them. The mean age of these two groups of patients was high SN-MP, $12.8{\pm}1.23$ years and low SN-MP, $13.0{\pm}1.48$ years. The following conclusions were obtained. 1. In the maxilla and mandible the mean tooth size of high SN-MP patients was nearlly identical to the low SN-MP patients. 2. The mean maxillary arch circumference was increased in low SN-MP group compared with high SN-MP group and a smilar, but smaller, mean increase was present in mandible. 3. The difference between the mean maxillary circumference required and the mean maillary circumference present ranged from -4.8mm in the high SN-MP group to -1.3mm in the low SN-MP group. A small range of means occurred in the mandible (high SN-MP: -4.0mm to low SN-MP: -1.8mm). 4. In the maxilla and mandible the mean arch length was nearly identical in the high and low SN-MP groups. 5. The mean incisor inclination was increased as the SN-MP angle decreased in the maxilla and mandible. 6. The men distance of the maxillary first molar from anterior border of the pterygomaxillary fissure was nearly similar between high and low groups. 7. The mean mandibular intermolar width was increased from high SN-MP to low SN-MP patients.

  • 이 연구는 저신장의 원인에 따른 치열궁 발육의 차이점을 분석하여 교정치료의 방향을 설정하는 것을 목적으로 한다. 저신장 진단을 받은 소아들에 대해 치과 진단 검사를 시행하였다. 성장호르몬 부족이 원인인 저신장 소아의 연령과 성별을 기준으로 하여 짝진 표본추출(paired sampling)을 하여 특발성 원인 저신장 소아를 분류하였다. 대조군은 1급 부정교합이고 arch length discrepancy가 3mm 미만인 대상자들을 선정하여 동일한 방법으로 분류하였다. 결론적으로 성장호르몬이 부족하거나 특발성 원인을 가진 저신장 소아에서 정상 소아에 비해 총생의 발현율이 더 높았고 수직피개 값은 작았다. 그러므로 저신장 소아의 교정치료는 총생을 치료하기 위해 조기에 Arch length discrepancy에 대한 평가를 포함한 치료계획을 세워야 할 것이다. 본 연구는 저신장 소아의 치열교합의 특성에 따른 성공적인 교정치료를 위한 중요한 자료를 제공할 수 있을 것으로 기대한다.
