牙周病是牙齿支持组织的破坏性疾病,病变可波及牙周膜、骨组织、牙骨质和覆盖的软组织。造成这些组织破坏的原因是各种各样的,过去牙周治疗中的一些失败多在于没有去除或忽视了病因,目前人们越来越多地注重了这方面的探讨。当牙齿发生排列异常及咬合异常时,牙齿周围的软硬组织的结构及承担生理功能的状况必然随之发生相应的改变。如果这些变化超出了机体可调节的范围,就可能对牙齿支持组织的健康造成威胁。
Periodontal disease is a devastating disease in tooth-supported tissues that can affect periodontal ligament, bone tissue, cementum, and soft tissue covered. The reasons for the destruction of these organizations are various. Some of the failures in the past periodontal treatment have mostly failed to remove or neglect the cause. At present, people pay more and more attention to this aspect. When the teeth are arranged abnormally and bite anomaly, the structure of the soft and hard tissues around the tooth and the situation of taking on the physiological function are bound to change correspondingly. If these changes go beyond the body's accommodative limits, they can pose a threat to the health of tooth-supported tissues.
