다양한 자세에서 교합장치의 두께가 저작근에 미치는 영향을 근전도학적으로 평가하고자, 측두하악장애의 징후와 증상이 없고 정상교합을 가진 성인 8명을 대상으로, 교합장치를 장착하지 않은 상태에서와 4.3, 6.0, 8.1mm 두께를 가진 교합장치를 장착한 상태에서 직립위, 식사위 그리고 앙와위에서 최대 이악물기 상태의 좌, 우측 교근 몇 전측두근의 근활성도를 채득, 분석하여 다음과 같은 결과를 얻었다. 1. 전측두근에서는 교합장치를 장착하지 않은 상태보다 교합장치를 장착한 상태에서 근활성이 유의하게 감소하였고 (p<0.05), 교근에서는 차이가 없었다. 2. 직립위에서 전측두근의 근활성은 교합장치를 장착하지 않은 상태보다 8.1mm 두께의 교합장치를 장착한 상태에서 유의하게 감소하였다 (p<0.05). 3. 식사위에서 전측두근의 근활성은 교합장치를 장착하지 않은 상태보다 8.1mm 두께의 교합장치를 장착한 상태에서 유의하게 감소하였다 (p<0.05). 4. 앙와위에서 전측두근의 근활성은 교합장치를 장착하지 않은 상태보다 4.3, 6.0, 8.1mm 두께의 교합장치를 장착한 상태에서 유의하게 감소하였다 (p<0.05).

Purpose: The aim of this study was to compare changes of bite force, occlusal contact area, and dynamic functional occlusion analysis after occlusal stabilization splint therapy during sleep for one month in a patient with bruxism. Materials and Methods: From October 2021 to July 2022, sleep bruxism of 30 patients who visited the Department of Oral Medicine at Yonsei University College of Dentistry Hospital were recruited. The participants were divided into two groups: using an occlusal stabilization splint during sleep (treatment; n = 15) and not using an occlusal stabilization splint (control; n = 15). Before using the occlusal stabilization splint and one month after, bite force, occlusal contact area and dynamic functional occlusion analysis (ratio of left/right bite forces, average bite forces, maximum bite forces, and maximum contact areas during lateral and anterior and posterior mandibular movements) were performed. Results: There was no difference in bite force and occlusal contact area between the treatment group using the occlusal stabilization splint and the control group not using the occlusal stabilization splint during sleep for one month. However, there were significant differences in the average bite force and maximum bite force in the lateral and anterior and posterior mandibular movements and the maximum contact areas in the anterior and posterior mandibular movements. Conclusion: The occlusal stabilization splint is helpful for sleep bruxism patients who lateral and anterior and posterior mandibular movements. In addition, further studies are needed a double-blind study with a large population.

악관절 잡음과 동통,과두 흡수를 동반한 퇴행성 측두하악장애는 교합 불안정과 개구장애 를 동반하기도 한다. 진단을 위해 CT나 MRI를 이용해 과두 형태 및 디스크 위치를 파악하 는 것이 유용한 접근법이다. 퇴행성 측두하악관절 환자는 CT나 MRI를 이용하여 진단하고, 과두-원판 재위치와 근 기능 개선을 위해 장기간 교합 안정장치 사용이 필요하므로 교정치료 기간에 변형된 교합 안정장치의 병용이 필요하다. 이에 본 연구에서 교합 안정장치를 병용하여 교합 재구성 증례를 CT나 MRI로 고찰해 보고자 한다.

This study was done to identify the changes of bite force and occlusal contact between before and after stabilization splint therapy. 16 female patients, accepted for orthodontic treatment at the Department of Orthodontics, College of Dentistry, Chosun University, were selected as the sample of this investigation. For comparisons, the samples of 16 were divided into just before stabilization splint, 1 month after stabilization splint, 2 months after stabilization splint, and 3 months after stabilization splint and used the T-scan system to identify the bite force and occlusal contact changes for each group. Statistical analysis of the data was carried out ANOVA tests, and Turkey tests using $SPSS/PC^+$. The results were as follows : 1. Bite force change from just before treatment to 1 month after stabilization splint therapy was statistical significantly decreased (P<0.05). 2. Bite force changes from 1 to 3 months after stabilization splint therapy showed no statistical significance (p>0.05). 3. The changes of anterior occlusal contacts showed no statistical significance regardless of the wearing periods of stabilization splint (P>0.05). 4. The changes of posterior occlusal contacts from just before treatment to 1 month after stabilization splint therapy was statistical significantly decreased (P<0.05). 5. The changes of posterior occlusal contacts Outing 1 to 3 months after stabilization splint therapy showed no statistical significance (P>0.05). 6. Posterior teeth rather than anterior teeth were more influenced by the changes of the number of occlusal contacts. To sum up above results, we may respect to capturing and stabilizing centric relation Position just 1 month after stabilization splint therapy.

지난 수십여 년 간 턱관저 및 저작근의 질환과 광범위한 보철 및 교정 수복 시 사용되었던 교합안전장치의 작용기전에 관하연느 아직 논란이 많다. 그러나 현재까지의 연구는 기존의 하악을 생리적으로 안정된 위치로 변화시킨다는 개념보다는 구강 내 장치가 위치함으로 인해 저작계의 행동변경(behavioral modification)으로 인해 구강 내 부기능적인 습관이 일시적으로 개선되는 것이라는 개념이 지배적이다. 좀 더 면밀히 말하면 이에 대한 보다 체계적인 연구가 필요한 게 사실이다. 본문에서는 그동안 사용되었던 여러 교합안전장치의 제작법 중에서 교합기를 이용하는 방법을 기공과정을 통하여 알아보고자 한다.

Stabilization splint therapy Precedes orthodontic intervention to enable the operator to find a 'true' centric(which is stable and comfortable), to test the patient's response to a change in the occlusion, prior to embarking upon a complex course of occlusal therapy : and finally, to see if the centric relation position can be stabilized. For this study, 47 malocclusion Patients enrolled for orthodontic treatment at the Department of Orthodontics, College of Dentistry, Chosun University comprised the malocclusion group, little variation of growth factor by the second molar eruption. They had Cr-Co discrepancy beyond normal range. For each patients the stabilization splint with mutually protected type of occlusal scheme was applied for 3 months. Condylar positions in CR and CO were measured using Penadent articulators, Panadent condylar position indicator(CPI), and transcranial projection before & after stabilization splint therapy. On the basis of this study, the results of this study were as follows 1. In all samples using CPI, there were statistical significances in CR-CO discrepancy(p<0.001) both before 8t after stabilization splint therapy. 2. In Rt and Lt+Rt/2 of superior joint space using transcranial projection, there were statistical significances in CR-CO discrepancy({<0.05) before & after stabilization splint therapy. 3. In supero-inferior components using CPI, there were statistical significances in CR-CO discrepancy(p<0.01) before & after stabilization splint therapy. 4. In all components except Rt using transcranial projection, there were no statistical significances in CR-CO discrepancy(p>0.05) before & after stabilization splint therapy. To sum up, CPI might be more effective than transcranial projection to reveal the changes between CR-CO discrepancies and stabilization splint might be more useful appliance for displaying the vertical changes, than the antero-posterior changes, of condylar position.

A patient with para-functional habits can cause widespread teeth wear, along with temporomandibular joint disorders and myofascial pain syndrome in the masticatory muscles. Prolonged teeth wear is associated with a decrease in vertical occlusal dimension, leading to issues such as changes in facial morphology, decreased masticatory efficiency, and temporomandibular joint disorders. To achieve a three-dimensional full-mouth rehabilitation in patients with decreased vertical occlusal dimension, accurate diagnosis, analysis, and proactive treatment planning are essential. Prosthetic treatment accompanied by the restoration of physiological vertical occlusal dimension and the re-establishment of a normal occlusal plane is necessary. This case report presents a full-mouth rehabilitation case involving a patient with overall teeth wear, showing decreased vertical occlusal dimension which results in discomfort in the temporomandibular joint and aesthetic dissatisfaction. The report highlights the successful outcome achieved through the use of occlusal stabilization splint for temporomandibular joint stability and Gothic arch tracing devices for the re-establishment of intermaxillary relationships. Also, through adjustments and adaptation assessment using provisional prostheses, favorable outcomes were achieved both functionally and aesthetically.

In this study, a minimum amount of the vertical occlusion was secured differently in each type of mandibular advance devices snoring and Class I malocclusion patients wore these devices. This study analyzes, after the use of devices, a different amount of the vertical occlusion results in a change of the area of upper airway by additional changes such as mandibular position, muscle changes, tongue position. The higher the vertical amount, the area of the upper airway was shown smaller, And if the patient's tongues was prevented from the distal movement, the area of the upper airway had increased, To reduce snoring, doctors should accurately diagnose patients' occlusal relationships and select a MAD snoring that is appropriate for the occlusion. The dental technician who builds the selected device should also consider design settings such as the amount of vertical occlusion, the finish lines, and the thickness of the device to increase the effectiveness of the device.
