Evaluation of clear aligners attachment success rate with different composite types

Abstract

This study aimed to evaluate the survival rate of clear aligner attachment using different composite types. Twelve patients ranging from 15 to 25 years old participated in this research. Patients who met the inclusion criteria were randomly assigned to one of two groups: packable composite, which contained packable composite attachments, or flowable composite, which included flowable composite attachments. There was no statistical difference in attachment failures between the two groups for all cases (2 = 3.003, P = 0.083) and individual cases. However, failures occurred in 75% of the FC group vs. 55.6% for the PC group (categorical data were compared using the Chi-Square or Fisher's exact test). According to the findings of this research, the composite type, whether packable or flowable, did not affect attachment failure.
