In this paper two cases treated with lingual orthodontics will be presented. Both cases had Class I skeletal and dental malocclusion. The treatment objectives were; alignement in both arches, reduction of the excessive overjet and overbite, improvement of lip relation. Both cases were treated without extraction and bracket (7th generation, Ormco) positioning was performed directly on the malocclusion models. Total treatment period was 20 months in Case 1 and 18 months in Case 2. In both cases treatment objectives were achieved, favorable occlusal relationship and profile improvement were obtained by using lingual orthodontic appliances.
