Less than ideal interarch occlusal relationships rarely if ever cause significant untoward effects on the masticatory system. Parafunctional habits (such as bruxism and clenching) are responsible for excessive occlusal wear, fractured teeth, tooth mobility, the periodontal lesion of trauma from occlusion, fractured restorations, myofascial pain involving the muscles of mastication, and painful TMJs. Correction of the malocclusion with orthodontic procedures, restorative procedures, or occlusal adjustment by selective grinding will not control the parafunctional habits. Myofascial pain originating from the muscles of mastication is in an overwhelming number of cases a self-limiting problem. Therapy for this problem should not bring about any permanent physical changes to the patient's interarch occlusal relationships.
不理想的牙弓间咬合关系极少（如果有的话）会对咀嚼系统造成严重不良影响。异常功能习惯（如磨牙症和紧咬牙）会导致过度的咬合磨损、牙齿折断、牙齿松动、咬合创伤性牙周病变、修复体折断、涉及咀嚼肌的肌筋膜疼痛以及颞下颌关节疼痛。通过正畸程序、修复程序或选择性调磨进行咬合调整来纠正错牙合畸形并不能控制异常功能习惯。绝大多数情况下，源自咀嚼肌的肌筋膜疼痛是一个自限性问题。针对这个问题的治疗不应给患者的牙弓间咬合关系带来任何永久性的身体改变。
