1、盘钻法行上颌窦内提升同期种植体植入的实验研究【摘要】目的：本实验以建立动物模型的方法，比较和评估盘钻法与冲顶式行上颌窦内提升牙种植的效果，探求盘钻法行上颌窦内提升的可行性及优势，为其应用于临床提供理论依据。方法：对30个新鲜成年山羊头颅标本随机编号。拔除双侧上颌第三前磨牙及第一、二磨牙，随机选择一侧上颌为实验侧,用盘钻法行上颌窦内提升;另一侧为对照，用冲顶法提升。根据提升高度不同分为三组：A组提升3mm,B组提升5mm,C组提升8mmo同期植入种植体，共计180个位点。对术后形态、黏膜完整度、种植体稳定度、组织学观察进行分析。结果：实验侧在影像学、形态学、黏膜穿孔率、种植体稳定度均
2、优于对照侧，有统计学意义。结论：用盘钻法行上颌窦内提升牙种植具有可靠性及可行性,对临床有指导意义。【关键词】牙种植；上颌窦内提升；盘钻；动物实验[Abstract】Methods：Thirtyfreshskullsofadultgoatsarenumberedrandomly.Thethirdpremolar,thefirstandthesecondmolarsofbilateralmaxillaewereextracted.Onesideoftheskullswasrandomlychosenastheexperimentalside,onwhichtheDisk-upSinus
