上颌窦三维成骨模式促进上颌窦内成骨的临床意义

Clinical implications of 3-dimensional osteogenesis model for maxillary sinus to promote osteogenesis in maxillary sinus

“上颌窦三维成骨模式”(3-dimensional osteogenesis model for maxillary sinus,3D-OMMS)的提出阐明了上颌窦底提升的成骨机制,为临床中上颌后牙缺失患者进行上颌窦底提升的治疗提供了科学的理论依据。本文结合临床病例,从施耐德膜的成骨潜力、双骨皮质支持、骨增量材料的应用及种植体表面改性四个方面阐述了“3D-OMMS”促进上颌窦内成骨的机制和临床意义。临床应用中包括单颗牙或多颗牙;即刻和延期种植;穿牙槽嵴上颌窦底提升以及侧壁开窗上颌窦底提升等术式,通过患者术前术后的计算机体层扫描(cone-beam computed tomography,CBCT)影像评估上颌窦区成骨效果。可见应用3D-OMMS,在上颌窦中形成成骨方向多元化的三维空间,缩短血管化成骨路径、加速成骨进程、提高新骨质量、增加种植成功率,因此在临床工作中可以被广泛应用。

The"3-dimensional osteogenesis model for maxillary sinus"(3D-OMMS)elucidated the osteogenic mechanism of maxillary sinus floor elevation.It provides a scientific theoretical basis for the treatment of maxillary sinus floor elevation in patients with missing maxillary posterior teeth.This manuscript reports the clinical application of"3D-OMMS"in the implants including single tooth or multiple teeth,immediate and delayed implants,transalveolar sinus floor elevation and lateral window approach sinus floor elevation,respectively.Preoperative and postoperative cone-beam computed tomography(CBCT)images were used to evaluate the osteogenic effect of the maxillary sinus region.In conclusion,the application of 3D-OMMS can form a three-dimensional space with diversified osteogenic directions in the maxillary sinus,shorten the vascularization osteogenesis path,accelerate the osteogenic process,improve the quality of new bone,and increase the success rate of implantation,which can be widely used in clinical practice.
