With regard to the optimal treatment timing for children with an Angle Class II division 1 malocclusion, there is an ongoing controversy on the effectiveness of a two-phase or a one-phase therapy. Two-phase treatment involves a first phase to correct the jaw relationship starting at the age of 7 to 9 years, and, when all permanent teeth are present, a second phase of treatment by fixed appliances. A one-phase treatment involves treatment of the jaw relationship and the dental malocclusion simultaneously or consecutively, starting during the early adolescence period. In recent years, several randomized controlled clinical trials have been performed on this topic. More recently, a Cochrane meta-analysis of these trials has been published. The results show that early treatment of an Angle Class II division 1 malocclusion followed by a second phase of treatment does not have any advantages over treatment that is started later and finished in one phase. One-phase treatment is as effective as two-phase treatment, while the time needed for treatment is shorter and, as a consequence, total costs are lower. Dentists should take into account this information, when treating children with an Angle Class II division 1 malocclusion or referring them to an orthodontist.
