摘要
目的:报道颧骨种植体在上颌后牙区骨质严重萎缩和缺损患者中的临床应用。方法:在4例患者中共植入7枚颧骨种植体和13枚常规牙种植体。所有患者术前均行颌骨三维CT重建,采用3D打印技术制作1∶1颌骨模型,设计颧骨种植体植入的位置和方向,按Branemark颧骨种植体植入术方法操作。结果:7枚颧骨种植体和13枚常规牙种植体植入轴向和位置理想,植入后1-7天行临时性固定义齿修复,3个月后行永久性义齿修复,追踪观察6个月至2年,义齿正常行使功能。结论:穿颧种植是上颌后牙区骨质严重吸收和上颌骨缺损患者咀嚼功能重建的一种可行方法。
Objective:To report the clinical application of zygomatic implants in patients with severe bone atrophy and defect in maxillary posterior regions.Methods:7 zygomatic implants and 13 conventional dental implants were implanted in 4 patients.3 D CT reconstruction of jaws was performed in all patients before operation.A 1:1 maxillary models were made using 3 D printing technique to design the locations and directions of implantation of zygomatic implants,according to the Branemark zygomatic implant method.Results:7 zygomatic implants and 13 conventional dental implants were implanted in ideal axial and position.Temporary fixed denture rehabilitation was performed from 1 to 7 days after implantation,and permanent denture rehabilitation was performed after 3 months.Followed up for 6 months to 2 years,dentures function normally.Conclusion:The zygomatic implantation is a feasible method for the reconstruction of masticatory function in patients with severe bone absorption and maxillary defect.
