Introduction: Class II malocclusion is characterized by
distoclusion and is divided into two divisions depending on the
inclination of the upper front teeth. The first division is
characterized by protrusion of the upper front teeth. Treatment
possibilities of class II/1 malocclusion depend on the skeletal form.
Therapy of dentoalveolar types of class II/1 malocclusion is exclusively
orthodontic. More emphasized skeletal forms of class II/1 malocclusion
may require surgery apart from orthodontic therapy.
Casse raport: In this paper, the extraction and nonextraction
treatment of 13 years old patients - M.P.(boy) and I.T. (girl) was
shown, respectively. The diagnosis was based on clinical and functional
intraoral findings, analysis of dental casts, face photos,
orthopatomogram and profile x-ray.
Nonextraction therapy was suggested for a boy and extraction therapy for
a girl, combined with the use of upper and lower fixed appliances. In
the treatment, technique of straight arch, Dentaurum brackets, root
prescriptions, slot 22 were used. In the male patient, there was a
slight maxillary prognathism, mandibular retrognathism, anterior type of
growth, protrusion of the upper incisors and retrusion of the lower
ones. The body of maxilla was shorter by 4 mm with regard to the cranial
base. In the female patient the extraction of the upper first premolars
was performed because of maxillary prognathism, mandibular retrognathism,
increased length of the body of maxilla, decreased length of the body of
maxilla and severe protrusion of the upper frontal teeth. After the
treatment, functional occlusion and improvement in facial aesthetics was
achieved in both patients. Facial changes were more apparent in the
patient who underwent the extraction treatment. After completion of
treatment, it is necessary to maintain the obtained results.
