影响上颌窦骨移植材料稳定的研究进展

Research Progress in Influence on Stability of Maxillary Sinus Bone Graft Materials

上颌窦提升术是解决上颌后牙区垂直骨量不足的常规手段,骨移植材料的长期稳定对上颌窦提升术的结果至关重要,也是影响种植体远期成功率的重要因素。上颌窦内的骨移植材料一般在术后6个月左右成熟稳定,但均会发生一定程度的体积吸收。少量吸收通常不会引起种植体周围骨的不稳定,但也有骨移植区缩减影响种植体的情况。影响上颌窦骨移植材料长期稳定的因素较为复杂,并非单一因素所致。然而,目前对影响骨移植材料三维体积变化的研究较少,未来需更多大样本量的统计与组织学研究证实。

Maxillary sinus augmentation is a common method to solve the problem of insufficient vertical bone mass in maxillary posterior teeth.The long-term stability of bone graft material is very important for the results of maxillary sinus elevation,and it is also an important factor affecting the long-term success rate of implants.Bone grafting materials in the maxillary sinus are generally mature and stable about 6 months after surgery,but all of them may have a certain degree of volume absorption.A small amount of absorption generally does not cause instability of the bone around the implant,but there are cases where the reduction of bone graft area affects the implant.The factors affecting the long-term stability of maxillary sinus bone graft materials are complex.However, there are few studies on the effect of three- dimensional volume change of bone graft materials,and more large sample size statistical and histological studies are needed in the future.
