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.
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.
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 (P<0.01). There were significant differences in the stripping length of the three groups by the SNK test (P<0.05).
CONCLUSIONS: The nickel-titanium dual-stage 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. .
比较镍钛双阶段上颌窦黏膜剥离器0.012和0.014型号以及伞状剥离器所获得的剥离长度。
选取24只1.5 - 2岁的山羊，随机分为A、B、C组，每组8只。A组为0.012型号组，B组为0.014型号组，C组为伞状剥离器组。建立动物模型，三组均对上颌窦底部左右两侧的黏膜进行剥离。在剥离至极限或穿孔时测量数据。
A组平均长度为(12.41±4.35)mm，2例穿孔；B组平均长度为(23.38±4.84)mm，1例穿孔；C组平均长度为(2.61±0.30)mm。经方差分析，三组剥离长度的总体均数不全相同(P<0.01)。经SNK检验，三组间剥离长度差异有统计学意义(P<0.05)。
镍钛双阶段上颌窦黏膜剥离器可获得较大的黏膜剥离范围。0.014型号的剥离器柔韧性和安全性适中，能够剥离较大面积的窦黏膜。
