Treatment of open bite malocclusion at the end of growth and in adult patients is challenging and includes several treatment alternatives to solve the problem. The publications are scarce on the long-term stability, but suggest that relapse is common. This presentation aims to illustrate with case reports and retrospective studies the stability or relapse in long-term treatment of open bite. Certain characteristics will be analyzed to predict the stability or relapse, such as the severity of the problem, the therapeutic approach used, and the quality of results at the end of treatment.
