Flowable composite resin is a type of dental composite resin that has a low viscosity and can flow on a surface. As a result, they are simply applied using a syringe. Despite their popularity in operative dentistry, these materials have yet to find a place in the field of orthodontics. Some orthodontists also use flowable composite resins for the temporary opening of the patient’s bite and have recently been used as an adhesive for orthodontic brackets and fixed orthodontic retainers. An updated literature review on the application of flowable composite resins in orthodontics is the objective of this research.
