Description

A primer in orthodontic treatment is a liquid adhesive applied to etched teeth to improve the bond strength between the bracket and enamel. Its purpose is to fill in the roughened surface left by etching, which helps create a stronger, more reliable bond between the bracket and the tooth. While some research questions whether a primer is essential for achieving clinically acceptable results, it is generally recommended by manufacturers to enhance bonding and reduce bracket failures. How primers are used in orthodontics Etching: A mild acid is first used to roughen the surface of the tooth enamel, creating a microscopic landscape for the adhesive to bond with. Priming: A liquid primer is then applied to the etched surface. It flows into the pores, acting as an intermediary agent that enhances adhesion.
