Dentistry is essential to maintain good general health, since dental problems can affect the health of the rest of the body. Orthodontics is a specialty of dentistry that is responsible for preventing, diagnosing and correcting dental malpositions and irregularities in the jaw. The dental world is constantly changing, so the use of alternatives in orthodontic treatment presents greater susceptibility to innovation and implementation of new techniques. The objective of this research is to found a new alternative to complete orthodontic treatment in the final stage. A clinical case of a teenager was shown, whose treatment was prolonged due to the COVID-19 pandemic. The use of fluid resin pins was used on the teeth and elastic therapy was performed. Correct settlement was evident after two months of treatment. Measures are proposed to maintain people's oral health after orthodontic treatment with fixed or removable techniques. Furthermore, the importance of treatment in adolescents is noted.
