Bonded orthodontic retainers:a review

Recent reports have suggested that long-term retention may be required to prevent posttreatment changes. The bonded orthodontic retainer constructed from composite and multistrand orthodontic wire provides an esthetic and efficient system for maintained retention. The development, indications for use, and clinical techniques are described. The range of materials reported for clinical use in construction of bonded orthodontic retainers are reviewed. Recommendations based on the literature are made. This review implicates placement of insufficient resin or use of a resin with inadequate abrasion resistance in the failure of bonded fixed retainers. (AM J ORTHOD DENTOFAC ORTHOP 1995;108:207-13.).
