用于成功治疗颞下颌疾病（TMD）的咬合夹板的作用机制仍然不清楚和有争议。本研究的目的是观察在睡眠磨牙症（SB）中使用平面前侧导向夹板（FGS）消除咬合影响时下颌的反应。使用该工具测量下颌运动模式和髁突位置的任何变化。使用Brux Checker®（BC）评估当前天然牙列上的SB活性，并与153名受试者插入FGS后的活性进行比较。下颌骨的空间位置各有不同，有向前和向下运动的趋势。FGS的植入导致髁突-窝关系的改变，似乎为颞下颌关节创造了一个“卸载”条件。研究发现，上颌门牙角度的增加是睡眠时肌肉活动改变的原因。咀嚼器官似乎是自我调节的，并提供了一种口腔行为的改变，这可能是更生理的使用FGS作为补偿因素。在这种情况下，可以假设睡眠磨牙症的副功能活动是咀嚼器官的生理功能。本研究结果表明控制前路引导在人类咬合功能重建中的重要性。
The mechanism of action of occlusal splints used for the successful treatment of temporomandibular disorders (TMD) remains unclear and controversial. The aim of this study was to observe the mandibular response during sleep bruxism (SB) on the elimination of occlusal influences by using a flat anterior and lateral guidance splint (FGS). Any changes in mandibular movement patterns and condylar position with the introduction of this tool were measured. Current SB activity on the natural dentition was evaluated using a Brux Checker® (BC) and compared with the activity after insertion of an FGS in 153 subjects. The spatial mandibular position changed individually with a tendency toward forward and downward movement. The insertion of an FGS led to a change in the topographical condyle-fossa relationship and seemed to create an “unloading” condition for the temporomandibular joint. It was found that increased angulation of the maxillar incisors was responsible for altered muscular activity during sleep. The masticatory organ appears to self-regulate and to provide an oral behavior modification, which may be more physiological using the FGS as a compensating factor. In this context, it is assumed that sleep bruxism in terms of parafunctional activity is a physiological function of the masticatory organ. The results of this study indicate the importance of controlling anterior guidance in the functional reconstruction of human occlusion.
