Research summary
Following completion of active brace treatment, the teeth are held in their new position by orthodontic appliances known as retainers. A number of different types of retainer are currently in use, with little evidence as to which is the best type. One of the most common types of retainer are bonded retainers (a metal wire glued to the back of the front teeth only). Many different types of bonded retainer exist, including customised laboratory manufactured bonded retainers and bonded retainers that are fitted chairside. It is not known which type of bonded retainer is better at holding the final tooth position following orthodontic treatment.
We would like to undertake a randomised controlled clinical trial to determine which is better; a customised laboratory manufactured bonded retainer or a bonded retainer that is fitted chairside. The aim of this research is to compare the stability (how well the teeth are held in their new position following orthodontic treatment), survival rate, patient satisfaction and cost-effectiveness of these two different types of bonded retainer.
