Article Synopsis
- This study aimed to investigate how different impression-taking methods affect bond strength when preparing tooth surfaces for bonding brackets.
- Three groups were tested: a control group with no impressions, a group using silicone impressions, and a group using polyether impressions, after etching the enamel with acid.
- Results showed that the silicone impression method resulted in the lowest bond strength, while polyether impressions did not significantly affect bond strength, suggesting polyether is suitable for surface replication in future studies on enamel preparation techniques.
