ABSTRACT
OBJECTIVE@#This work aims to investigate the effect of stripping of steep sheep maxillary sinus by using 0.012 or 0.014 model new-type memory elastic silk sleeve stripper and umbrella stripper.@*METHODS@#Goats with sinus floor gradients of 60° to 90° were selected by computed tomography of sheep head. A total of 72 animal models were established and randomized into three groups (n=24): group A (0.012 model), B (0.014 model) and C (umbrella stripper). Alveolar and maxillary sinus mucosa were stripped after crowning, and stripping length was measured when the stripping limit was reached or mucosal perforation occurred.@*RESULTS@#The average stripping length of mucosa in group A was 11.3 mm±4.6 mm, and three cases experienced perforation of sinus floor mucosa. The average stripping length of mucosa in group B was 17.5 mm±5.0 mm, and one case experienced perforation of sinus floor mucosa. The average stripping length of mucosa in group C was 4.2 mm±1.3 mm, and four cases experienced perforation of sinus floor mucosa. The difference among the three groups was statistically significant (P<0.01) according to variance analysis. Moreover, the comparison between any two means was also statistically significant according to Dunnett's T3 test (P<0.05).@*CONCLUSIONS@#The new-type memory elastic silk sleeve stripper effectively stripped steep maxillary sinus mucosa. The 0.014 model exhibited superior peeling effect and was relatively safe.
