In recent years laser technology has played an increasingly important role in modern dentistry and, recently, the utilization of laser devices has also been proposed in orthodontics.
The aim of this work is to describe the use of combined laser devices (Fidelis and LightWalker AT, Fotona, Slovenia: 1064 nm and 2940 nm) in soft and hard oral tissues to improve orthodontic treatment. Several cases treated by Er:YAG and Nd:YAG in different stages of the treatment (before, during and after) are presented. All the cases showed, as reported in the literature, that the use of lasers with orthodontic treatment offers several advantages when compared to conventional methods.
In soft-tissue surgery, it allows practitioners to reduce or eliminate the use of anesthetic injection, to avoid the use of sutures and to bond brackets in dry enamel. Combined with orthophosphoric acid, it provides a stronger adhesion of the brackets to the enamel and helps to prevent carious lesions around the brackets. It may even be used to repair broken appliances by welding them intra-orally.
