BONDING
There have been many recent studies on the effectiveness of orthodontic retainers. As a result, we are getting a substantial body of good clinical evidence on their use. However, trials consistently show a high failure rate for bonded retainers. Consequently, more research is being conducted to find ways to address this issue. One approach involves considering sandblasting the enamel surface as part of the bonding protocol. This study examined the effectiveness of this method.
