目的 面对上颌磨牙区偏离牙弓曲线水平向严重缺损伴骨高度不足,本病例尝试选用钛网作为支架,联合上颌窦底提升术实现局部区域的水平向和垂直向骨增量.方法 患者术前CBCT显示,26 牙位处剩余骨宽度约 3.3 mm,高度约 4.9 mm,27 牙位处剩余骨宽度约 5.2 mm,高度约 5.1 mm.病例治疗采用了钛网维持颊侧水平向成骨空间,采集自体骨混合人工骨植骨,并应用富血小板纤维蛋白,同时联合侧壁开窗上颌窦底提升术改善垂直向骨量.结果 术后 5 个月,取出钛网,CBCT显示,26 牙位处较术前骨宽度增加了 2.0 mm,高度增加了 3.2 mm;27 牙位处较术前骨宽度增加了 1.2 mm,高度增加了 4.0 mm,获得了理想的骨增量效果.术后 6 个月,进行经牙槽嵴顶上颌窦底提升术和种植体植入术,种植体初期稳定性良好.术后1 年,种植修复完成,CBCT显示,26 牙位处较术前骨宽度增加了 2.9 mm,高度增加了 4.5 mm;27 牙位处较术前骨宽度增加了0.9 mm,高度增加了6.6 mm,结果显示骨增量效果稳定,恢复了正常的咬合功能,并取得一定的美学效果改善.结论 该病例结果表明,钛网植骨联合上颌窦底提升术可以获得较为充分稳定的骨增量效果,是一种可靠的用来改善上颌磨牙区骨量不足的方法.
Titanium mesh bone grafting combined with maxillary sinus floor elevation to improve severe bone defect in maxillary molar area:A case report
Objective To handle severe horizontal defect of maxillary molar area deviating from dental arch curve with insufficient bone height,this case tried to use titanium mesh as a scaffold and combine maxillary sinus floor elevation to realize horizontal and verti-cal bone increment in local area.Methods Preoperative CBCT showed that the residual bone in 26 teeth was about 3.3 mm in width and 4.9 mm in height,and that in 27 teeth was about 5.2 mm in width and 5.1 mm in height.The patient was treated with titanium mesh to maintain buccal horizontal osteogenic space,and autogenous bone mixed with artificial bone was collected for bone grafting.At the same time,platelet-rich fibrin was applied,and the vertical bone mass was improved by lateral maxillary sinus floor elevation.Re-sults Five months after operation,the titanium mesh was removed.CBCT showed that the bone width and height of 26 teeth were re-spectively increased by 2.0 mm and 3.2 mm compared with those before operation.The bone width and height of 27 teeth increased by 1.2 mm and 4.0 mm,and the ideal bone increment effect was obtained.Six months after operation,transalveolar maxillary sinus floor elevation and implant implantation were performed and the initial stability of the implant was good.One year after operation,the implant restoration was completed.CBCT showed that the bone width and height of 26 teeth were respectively increased by 2.9 mm and 4.5 mm compared with that before operation.The bone width and height of 27 teeth were respectively increased by 0.9 mm and 6.6 mm.The re-sults showed that the bone increment effect was stable;the normal occlusal function was restored,and the aesthetic effect was improved to some extent.Conclusion Results of this case show that titanium mesh bone grafting combined with maxillary sinus floor elevation can obtain a relatively sufficient and stable bone increment effect,and it is a reliable method to improve the bone deficiency in maxillary molar area.
