种植牙能延缓牙槽骨吸收吗 孟令强 河北医科大学口腔医院 大家知道牙跟骨头是伴生的，从咱们开始长牙的时候，牙槽骨就开始生长，所以我们形象的比喻为，它们俩是唇齿相依的，唇亡齿寒，当牙齿拔完之后，这个牙槽骨会迅速吸收，这是一个常识，也是一个不争的事实，而种植义齿，种完之后骨头能不能延缓它的吸收，这个在国内和国外的文献都有报导，它是可以做到的，因为颌骨在正常的生理状态下，它的吸收速度会减慢，文献报导，在国外很多病例里面会看到，同样一个病人，他有一个天然牙存在，另外一个有种植的义齿存在，当然是多个义齿，那么若干年之后再拍片子对照发现，天然牙已经没有了拔掉了，或者再做其他种植了，又做种植了，而它对侧的种植义齿的骨头，还是稳固的吸收的很慢，骨头高度很高，经过若干年对比来讲是成功的，就是说它每年的吸收速度，都在0.2以内，所以说这个种植体，是可以延缓牙槽骨吸收的，但是前提是要设计合理，维护合理，不发生种植体周围炎，不发生一些创伤，这样是完全可以达到的。 Can implant delay alveolar bone absorption We all know that teeth are associated with bones, When we started growing teeth, The alveolar bone begins to grow, So the metaphor of our image is, They are closely related to each other, if the lips are gone, When the teeth are pulled out, The alveolar bone absorbs rapidly, This is a common sense, It is also an indisputable fact, And implant dentures, Can bone delay its absorption after planting, This is reported in domestic and foreign literature, It can be done, Because the jaw is in a normal physiological state, Its absorption rate will slow down, Literature reports, In many cases abroad, The same patient, He has a natural tooth, Another implant exists, Multiple dentures, of course, Then we took a few years later and found that, No natural teeth have been extracted, Or do something else, We planted it again, On the other side, the bone of the implant denture, It's steady and slow to absorb, The height of the bone is very high, After several years of comparison, it is successful, That is to say, its annual absorption rate, All within 0.2, So this implant, It can delay the absorption of alveolar bone, But the premise is to design reasonably, Reasonable maintenance, No peri implant inflammation, No trauma, This is completely achievable.
