Phase 1 Retainer

This retainer is used to hold maxillary after expansion and phase I treatment. The purpose is to stabilize the arch and retain the erupted permanent teeth. There are variations, but the goal is to hold the central and lateral incisors along with the first molars. We use a 2-2 bow with or without a loop, or a 3-3 bow with spurs on the distal of the laterals. Adams clasps are best suited to allow exfoliation of the deciduous teeth and maintain retention. It is also recommended to relieve the lingual acrylic in the premolar area
