Fiber-reinforced composites as the 4th generation bonded retainers in orthodontics
The enigma of relapse has prevailed in orthodontics since early 1900s. Good stability of an orthodontic treatment relies on proper planning of retention protocol. Many retention protocols are in use by various clinicians, the most common being fixed lingual retainers since the degree of relapse is highly unpredictable. Bonded retainers offer advantages compared to conventional removable retainers in that they are invisible from the front, require less patient cooperation, and provide a long-term or even permanent retention.
