牙槽嵴保存技术

颌骨牙槽突随着牙齿萌出、牙根形成及其之后的生长而发育成型。牙槽骨、牙周韧带、牙骨质和牙体构成一个发育单位,因为它们一起形成。颌骨的不同区域牙槽突尺寸显著不同,而牙齿类型与牙槽突尺寸相关。遗传因素也会影响牙槽突尺寸。牙槽突由两类骨组织组成:固有牙槽骨(组织学上又称束状骨)和支持骨。束状骨组成了牙槽窝的内层部分,而牙槽突的其余部分由支持骨组成。束状骨是类似于牙骨质的牙周组织,它将牙周韧带连接至牙槽骨。当牙齿被拔除后,该发育单位将发生改变,牙槽突将发生骨吸收。

足够的牙槽嵴尺寸有利于将种植体植入合适的三维位置,并为种植体和软组织提供适当的机械支持。拔牙后,牙槽突骨吸收是不可避免的结果。最好能够预防或减少此类骨吸收,因为足够的骨壁厚度有助于口腔种植的长期成功。牙槽嵴保存是指为保存拔牙时的牙槽嵴骨量而进行的一种手术。
