Bonded fixed retainers are frequently used nowadays as the main—and often the only—retention protocol after orthodontic treatment. The expectations for long-lasting lifetime stability of the occlusion led orthodontists to seek the ultimate retention protocol with minimal patient compliance, including fixed retainers. However, fixed retainers have many disadvantages and risks that should be considered in advance. Different failures of fixed retainers are described and categorized, and the workflow for the retreatment of poor occlusion after relapse, despite the fixed retainers, is described. Three case presentations (open bite, root movement, and maxillomandibular protrusion) are described, and all received clear aligner treatment. A revised retention protocol is suggested.
