Case report. Adult Class II malocclusion with constricted arches, excessive vertical overlap and malposed teeth

The patient presented with constriction of both arches, moderate crowding, posterior crossbite, severe deep bite, TMJ symptoms and facial pain. The Crozat appliance therapy effectively uprighted the posterior segments and developed the arches. Alignment, leveling and development of a good functional occlusion was accomplished efficiently with the straight-wire appliance. Facial balance and good lip support was maintained. No stripping was present and the periodontal health remains excellent. An improvement was made in the patient's smile and TMJ health. The teeth have been stable during the three year period following the initial placement of retainers. And the patient is very pleased with the treatment results.
