中文摘要

目的 通过羊经牙槽突上颌窦底提升法,对比0.012型号、0.014型号镍钛双级上颌窦黏膜剥离器以及伞形剥离器剥离窦底黏膜的效果。方法 选择年龄1.5~2岁山羊24只,配伍组设计随机分成0.012型号组(A组)、0.014型号组(B组)、伞形剥离器组(C组),每组8只。建立动物模型,在上颌窦内提升冲顶后,3组分别向窦底的近中和远中剥离上颌窦黏膜至本器械的最大剥离限度或窦底黏膜穿孔时,测量剥离长度。结果 A组平均剥离长度为12.41 mm±4.35 mm,2例出现上颌窦黏膜穿孔。B组平均剥离长度为23.38 mm±4.84 mm,1例出现上颌窦黏膜穿孔。C组平均剥离窦底黏膜长度是2.61 mm±0.30 mm。经方差分析计算得3组剥离上颌窦黏膜总体均值不全相同(P结论 镍钛双级上颌窦黏膜剥离器在行上颌窦黏膜剥离能获得较大的黏膜剥离范围。0.014型号弹性及刃适中、安全,能够大面积剥离窦底黏膜。

英文摘要

Objective To compare the stripping length obtained through the model of 0.012 and 0.014 of the nickel-titanium dual-stage maxillary sinus mucosa stripper, and the umbrella detacher.Methods Twenty-four goats (1.5-2 years old) were chosen, randomly divided into A, B, C groups, each group of eight. Group A was 0.012 model group, group B was 0.014 model group, group C was umbrella detacher group. Animal model was established, and maxillary sinus mucosa was stripped to the left and right sides of the bottom of the sinus in three groups. The data was measured when stripping to the limit or being perforated.Results The average length of group A was 12.41 mm±4.35 mm, two cases perforated. The average length of group B was 23.38 mm±4.84 mm, one case perforated. The average length of group C was 2.61 mm±0.30 mm. The population mean of stripping length in three groups was not all the same calculated by analysis of variance (PConclusion The nickel-titanium dualstage maxillary sinus mucosa stripper can achieve a larger mucosal stripping range. The stripper with a model of 0.014 has a moderate flexibility and safety, and it can strip a large area of sinus mucosa.
