Aim: This study aimed to describe the various protocols for treating class II/1 malocclusion, determine the one-phase and two-phase treatment approaches, and identify the best time to provide effective and efficient treatment. Materials and Methods: An electronic search in four major databases - PubMed, Scopus, ScieLo, and Google Scholar - was completed on March 4, 2021. A search was performed on the orthodontic treatment of class II/1 over the last 10 years, and 2002 papers were obtained. Results: A total of 52 journal articles matched the inclusion criteria. Class II/1 malocclusion was more commonly found with class II/1 skeletal analysis, and one-phase treatment was preferred over two-phase treatment. One of the keys to successful treatment is the effectiveness of the treatment, which depends on the time of the treatment intervention and the appliance used. Conclusions: Determination of treatment is highly dependent on the characteristics of the malocclusion, age, and remaining growth. Due to the complexity of the case, knowledge and experience are needed in managing class II malocclusion.
