Orthodontic treatment is known to last as long as 18 or 24 months in average, which is one of the reasons adult patients and their dental caregivers frequently seek other alternatives to solve problems related with malocclusions. Skeletal mandibular prognathism is one of the rare malocclusions where the only treatment alternative is orthognathic surgery. The favorable treatment outcome of the case described in this article shows that limited orthodontics can accomplish a great improvement in the treatment of adults. The most difficult part for the patient was to live with the bite raisers that prevented the posterior teeth from occluding, so chewing ability was limited for the greater part of the treatment duration. However, the patientsâ acceptance of the appliance and the level of cooperation were high, probably due to the medical background, and he was very much satisfied with the treatment result. A side effect was seen in the mandibular dentition, the amount of crowding in the incisor region increased slightly. This was due to a change in the force-equilibrium of the dentition. As soon as a normal overjet was achieved, protrusive movements of the mandible were guided by the upper incisors, so that the protrusive force created a reactive force in the opposite direction acting on the lower incisors, who responded with slight retroclination.
