Impact of Pre-filled Resin on Attachment Loss Rate of Invisible Orthodontic Aligners

doi:10.13701/j.cnki.kqyxyj.2024.12.013

Abstract

Abstract: Objective: To explore the impact of pre-filled resin on the adhesion effectiveness of attachments for invisible orthodontic aligners. Methods: This study involved 60 orthodontic patients from the Department of Orthodontics at Anyang Sixth People's Hospital, including a total of 1002 attachments. The upper jaw was used to compare the attachment loss rates over 6 months between resin pre-filled 72 hours in advance and conventional chairside filled resin, while the lower jaw was used to compare the 24-hour pre-filled resin with the conventional method. Results: Both the upper and lower jaws demonstrated no significant statistical difference in attachment loss rates between the pre-filled groups and their respective conventional chairside filled groups. Conclusion: Pre-filling resin does not affect the adhesion of attachments and can be used to enhance clinical operational flexibility and efficiency.

Key words: invisible orthodontic aligners, attachment loss rate, pre-filled resin
