随着(牙合)学研究的进展,咬合异常(包括(牙合)与咬合)在牙周病、颞下颌关节紊乱综合征、磨牙症等疾病的发生和发展中所起的作用及在诊断和治疗方面的重要性,已日益得到广泛的重视。除各种错(牙合)引起的咬合异常需作正畸治疗,牙列严重磨损引起的咬合与颌位异常需作咬合重建修复外,大部分程度较轻的咬合异常可用(牙合)磨改的方法,通过对牙冠的少量磨改,以去除早接触和咬合干扰,改善咬合关系,使咀嚼系统各部分关系谐调,功能正常,从而保持健康。 (牙合)磨改需根据一定的原则,有顺序地进行,不正确的(牙合)磨改,不仅达不到治疗目的,甚至可造成新的咬合异常,故在选择适 With the development of occlusal science, the occurence and occurence of occlusal anomalies (including occlusion and occlusion) in periodontal disease, temporomandibular disorder, bruxism and other diseases and the role in the diagnosis And the importance of treatment, has gained increasing attention. In addition to all kinds of malocclusion caused by abnormal occlusion required for orthodontic treatment, severe dentition caused by occlusal and jaw abnormalities need for occlusal reconstruction and repair, most of the less severe occlusion available (occlusal) grinding Change the method, through a small amount of modification to the crown to remove the early contact and occlusion interference, to improve the occlusal relationship, so that the various parts of the chewing system to coordinate the relationship between the normal function to maintain health. (Occlusal) Abrasion should be based on certain principles, in an orderly manner, not correct (occlusal) Modification, not only failed to achieve the purpose of treatment, and even cause new bite abnormalities, so in the choice of appropriate
