Posterior crossbite might cause serious long-term functional problems if not early treated. Nevertheless, in older patients, treatment might include palatal expansion in order to correct such malocclusion. In view of the above, this article aims at reporting late correction of bilateral posterior crossbite associated with Angle Class III malocclusion, right subdivision, with consequent midline shift (good skeletal pattern). The case was presented to the Brazilian Board of Orthodontics and Dentofacial Orthopedics (BBO), with DI equal to or greater than 10, as a requirement for the title of certified by the BBO.

The treatment of Angle Class III malocclusion is rather challenging, because the patient’s growth pattern determines the success of long-term treatment. Early diagnosis and treatment are still highly discussed issues in orthodontic literature. This type of early intervention has been indicated more frequently in order to eliminate primary etiological factors and prevent an already present malocclusion from becoming severe. However, when a patient is diagnosed in adulthood, manipulation of the bone bases becomes extremely limited, as there is no longer any potential for growth. Treatments are restricted to dental compensations when possible or orthognathic surgery. However, owing to the high cost and inherent risk of the surgical procedure, this treatment option is often denied by the patient; in such a case, the orthodontist has little choice but to perform, where possible, compensatory treatments to restore a functional occlusion and improve facial esthetics. This article reports a case of Class III malocclusion in a patient who opted for compensatory treatment with lower molar extraction that allowed for correction of the midline and the overjet. Good facial esthetics and functional normal occlusion were achieved at the end of the treatment.

Angle Class III malocclusion is characterized by an inadequate anteroposterior dental relationship which may or may not be accompanied by skeletal changes. In general, patients are distressed by a significantly compromised facial aspect which, when associated with a deficient middle third, encourages patients to seek treatment. This article reports a two-phase treatment carried out in a female patient aged six years and six months with a tendency towards a Class III skeletal pattern. This case was presented to the Brazilian Board of Orthodontics and Facial Orthopedics (BBO). It is representative of the Discrepancy Index (DI) category, and fulfills part of the requirements for obtaining BBO Diploma.

INTRODUCTION: Angle's Class III malocclusion is a dental discrepancy in a sagittal view that may appear or not with an important skeletal discrepancy. Facial esthetics may be affected by this skeletal discrepancy and it is one of the most common complaints of patients who seek orthodontic treatment. Class III treatment, in adults, may be done by compensatory tooth movement, in simple cases, or through an association between orthodontics and orthognathic surgery, in more severe cases. OBJECTIVE: This article describes a non-extraction compensatory Class III treatment case, applying the Tweed-Merrifield mechanical principles with headgear (J-Hook) in the mandibular arch. This case was presented at the V Brazilian Association of Orthodontics and Dentofacial Orthopedics (ABOR) Meeting, it was evaluated by members of Brazilian Board of Orthodontics and obtained third place in the general classification.

Angle Class Iii Malocclusion

Many studies report that maxillofacial growth is influenced by genetic and environmental elements and that incorrect breathing, chewing, sucking, and swallowing are promoting factors of malocclusion. This study aims to evaluate the function and the influence of the tongue positions in patients with Angle class III malocclusion, maxillary hypoplasia, and posterior crossbite. One hundred patients, aged between 6 and 12 years old, were enrolled for the study. In the first group, patients with a diagnosis of class III malocclusion, affected by maxillary hypoplasia, skeletal class III, and posterior dental crossbite were recruited. In the control group, not treated patients with no malocclusion, skeletal class I, and without posterior dental crossbite were selected. Regarding atypical deglutition, no statistical differences were reported between the two groups, and 14% of patients reported ankyloglossia. Statistical differences were found in tongue rest position and during the execution of “hold and pull” and “chuck” exercises. Results obtained in this observational study showed that the clinician (orthodontist or general dentist) should analyze the presence/absence of atypical swallowing, the anatomical and functional aspects, and the tongue behavior in the rest position.

Objective: To determine prevalence of malocclusion and orthodontic treatment needs in Down syndrome individuals among Sudanese population in Khartoum area.Materials & Method: A total of 75 (37 males and 38 females) Down syndrome individuals age ranging from 6-28 years were clinically examined after obtaining their guardian’s consent, malocclusion was determined based on Angle and Incisor classification. Exclusion criteria were included individuals who had history of extraction and orthodontic treatment.Data was analysed by using SPSS Version 17, at an alpha level 0.05 and 95% confidence limits.Result: Angle Class III and Incisor III malocclusion represents the most prevalent type of malocclusions (58.7%) Angle classification, (53.3%) Incisors classification. Angle Class III malocclusion was more frequent among females (60.5%) than in males (56.8%). Themajority of individuals with Down syndrome are in need of orthodontic treatment (85.3%).Conclusion: The prevalence of malocclusion and orthodontic treatment need among Sudanese Down syndrome individuals was high. Angle and Incisor Class III malocclusion representing commonest trait of malocclusion with more frequency in femalesthan males.Key word: down syndrome, Class III malocclusion, orthodontic treatment

Angle Class III malocclusion results in aesthetic and functional concerns, thus it is essential that this malocclusion is treated as early as possible, so that dentocraniofacial development occurs properly. A 7-year-old male patient with Asperger's syndrome had a Class III subdivision right malocclusion, anterior and posterior crossbite. To gain the patient's trust and collaboration, we used the behavioral management technique tell-show-do, in addition to the behavioral analysis method.  Orthodontic treatment started using the Hyrax palatal expander, but the patient was not able to adapt to it. Correction of the crossbite was achieved using a removable expander with digital springs, which was better accepted by the patient and provided aesthetic and functional improvement.

Angle Class III malocclusion is characterized by anteroposterior dental discrepancy which might be associated or not with skeletal changes. Class III molar relationship is associated with vertical or lingually tipped mandibular incisors and a usually concave profile. These characteristics seriously affect facial esthetics and most frequently are the reason why patients seek orthodontic treatment. This case was presented to the committee of the Brazilian Board of Orthodontics and Facial Orthopedics (BBO) as part of the requisites to become a BBO Diplomate.
