正畸托槽不同粘结方法的粘结强度比较
Comparison of the bond strengths of different orthodontic bond Methods
摘要
Abstract
Objective To compare the difference of brackets bond strength between indirect bonding method and direct bonding method. Methods Ninety- six extracted human premolars for orthodontic reason were collected and randomly divided into group A,B and C (n=32 in each group). In group A, brackets were bonded to tooth by simply indirect bracket bonding techniques. In group B,brackets were bonded by the Sondhi method.In group C,we used the direct bracket bonding techniques.The adhesive residues and shear bond strength of brackets were detected. Results There was statistically significant in adhesive residues in three groups ( =19.35, <0.05), and group C was the largest.The adhesive residues in group A was smaller than group B, but with no statistically significant (=1.25, >0.05). There was statistically significant in shear strength in three groups ( =7.493, <0.05).The shear strength in group A (9.92±3.51) was no significantly difference compared with that in group B (9.38±2.09) ( >0.05). The shear strength of group C (12.41±4.09) was bigger than group A and B, and with statistically significant ( <0.05). Conclusion Compared with Sondhi method, our modified indirect bonding is with lower adhesive residues, higher shear strength, which can apply in clinical use.关键词
