“冰淇淋蛋筒技术”在上颌窦穿孔患者种植义齿修复中的应用1例

Application of "Ice-Cream Cone" Technique in Dental Implant Surgery for Patient with Oroantral Communication: A Case Report

口腔上颌窦穿孔(oroantral communication,OAC)是拔牙的常见并发症之一。未妥善处理的OAC会导致上颌窦底皮质骨不连续,上颌窦膜与口腔黏膜粘连,增加种植治疗的难度。本病例首次将“冰淇淋蛋筒技术”用于处理OAC,并同期行牙槽嵴水平骨增量,最后顺利完成种植修复。此技术操作简单,牛心包来源胶原膜和冰淇淋蛋筒共同形成稳定的成骨空间,可用于处理小直径OAC。

Oroantral communication(OAC)is a common complication following tooth extraction.Improperly treated OAC may result in the cortical bone discontinuity at the floor of maxillary sinus and the adhesion of maxillary sinus membrane to oral mucosa,so as to increase the complexity of implant treatment.In this case,for the first time,the"ice cream cone technique"was employed to address OAC,concurrently accompanied with horizontal bone augmentation.This innovative approach successfully facilitated implant surgery.The technique is characterized by its simplicity to create a stable bone-forming space through the ice cream cone technique using a collagen membrane from bovine pericardium,which is suitable to manage small-diameter OACs.
