四种上颌窦剥离器械对具有坡度上颌窦底黏膜剥离长度的对比研究

摘要

Objective: To evaluate stripping effect of the gradient maxillary sinus floor mucosa with home-made modified titanium nickel stripping device. Methods: On the basis of establishing immediate vi-sual model on the flat maxillary sinus floor mucosa of stripping length, using four kinds of the maxillary sinus stripping device to strip the floor of the maxillary sinus mucosa, umbrella stripping equipment group, probe the altered equipment group, 012 nickel titanium equipment group, the 014 nickel-titani-um equipment group respectively in group A and group B, C, D group, length of the four groups of stripping was analyzed by ANOVA and SNK (Student-Newman-Keuls) were compared between the two two groups. Rusults:Differences between the four groups were obvious statistical significance (P<0.01). After SNK, there were statistically significant between the two two groups. Conclusions: Compared with the other three stripping device for the gradient maxillary sinus floor, nickel-titanium instruments for stripping showed obvious advantages. The length of two nickel-titanium instruments were greater than umbrella stripping device and the probe modified stripping device. The effect of the maxillary sinus floor with the 014 nickel-titanium was better than that of the 012 nickel-titanium stripping apparatus.%目的：评估自制改良的镍钛剥离器械对具有明显坡度的上颌窦底黏膜剥离效果。方法：在建立即时可视的上颌窦底黏膜剥离长度模型的基础上，使用四种上颌窦剥离器械剥离上颌窦底黏膜，伞形剥离器械组、探针改良型器械组、012镍钛器械组、014镍钛器械组分别为A组、 B组、 C组、 D组，对四组剥离长度进行方差分析及SNK两两组间比较。结果： P<0.01，说明四组组间差异有明显的统计学意义， SNK比较说明，四组两两之间差异均有统计学意义。结论：对于具有明显坡度的上颌窦，相比较于其他三种剥离器械，镍钛剥离器械表现出明显的优势，两种镍钛剥离器械剥离黏膜的长度均大于伞形剥离器械及探针改良型剥离器械。014镍钛剥离器械剥离上颌窦底黏膜效果优于012镍钛剥离器械。
