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 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.

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.

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.

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

ObjectiveTo determine whether basing the decision to initiate immediate vs delayed disease-modifying therapy (DMT) on extent of recovery after initial relapse affects long-term disability accumulation in a multiple sclerosis (MS) evidence-based setting.MethodsWe analyzed the double-blind, placebo-controlled interferon beta-1a 30 mc once a week in clinically isolated syndrome and 10-year-follow-up extension trial. Good recovery after presenting relapse was defined as (1) full early recovery within 28 days of symptom onset (Expanded Disability Status Scale [EDSS] score of 0 at enrollment maintained ≥6 months) and (2) delayed good recovery (EDSS score > 0 at enrollment and improvement from peak deficit to 6th-month or 1-year visit ≥ median). Time from recovery assignment to future disability (EDSS score ≥ 2.5 or ≥4.0) was studied on a relapse-recovery-stratified age axis and immediate vs 3-year delayed treatment initiation with Kaplan-Meier statistics and hazard ratios (HRs).ResultsOne hundred seventy-five/328 patients had good recovery (94 immediate and 81 delayed treatment); 153 did not have good recovery (77 immediate and 76 delayed treatment). HRs for EDSS score ≥2.5 outcome were: delayed treatment without good recovery as reference (HR = 1.0), delayed treatment with good recovery (HR6th-month: 0.67, p = 0.207; HR1st-year: 0.40, p = 0.027), immediate treatment without good recovery (HR6th-month: 0.56, p = 0.061; HR1st-year: 0.40, p = 0.011), and immediate treatment with good recovery (HR6th-month: 0.43, p = 0.014; HR1st-year: 0.48, p = 0.034). Placebo patients were switched to long-term treatment after 3 years, and insufficient EDSS score ≥4.0 outcome events were available to study.ConclusionsIn patients with MS presenting without good recovery after the initial relapse, immediate DMT initiation favorably influences the likelihood of more ambulatory-benign disease akin to patients with good recovery after the initial relapse.Classification of evidenceThis study provides Class III evidence that for patients with MS without good recovery after the initial relapse, immediate DMT initiation increases the likelihood of a benign disease course.

Abstract Objective: To compare the cephalometric characteristics of children with Class III malocclusion to those of children with normal occlusion during the deciduous dentition phase. Materials and Methods: Cephalometric measurements of 27 children (mean age: 5.03 years) diagnosed with Class III malocclusion were compared with 32 children (mean age: 4.85 years) diagnosed with normal occlusion in the following four categories: sagittal skeletal analysis, vertical skeletal analysis, dentoalveolar analysis, and soft tissue analysis. Results: Significant differences were seen in all categories except vertical skeletal analysis. Sagittal skeletal measurements included ANB (Class III group: −0.91 ± 1.60; normal group: 5.28 ± 1.29), facial convexity (Class III group: 0.47 ± 4.32; normal group: 13.65 ± 3.44), Wits appraisal (Class III group: −5.54 ± 2.36; normal group: −0.84 ± 1.91), and A to N-perpendicular (Class III group: −2.94 ± 3.05; normal group: 0.78 ± 2.53). Dentoalveolar measurements included U1 to NA (Class III group: 11.98 ± 5.25; normal group: 8.12 ± 5.43), IMPA (Class III group: 81.34 ± 7.40; normal group: 86.57 ± 5.67), and interincisal angle (Class III group: 152.65 ± 8.82; normal group: 145.03 ± 7.34). Soft tissue measurements included soft tissue convexity (Class III group: 2.47 ± 4.20; normal group: 12.71 ± 3.95), nasofacial angle (Class III group: 22.68 ± 4.22; normal group: 26.24 ± 3.84), and upper lip to esthetic plane (Class III group: −0.65 ± 2.74; normal group: 3.07 ± 1.90). Conclusions: There are significant differences between the craniofacial patterns of normal children and those of children with Class III malocclusion that can be identified with cephalometric analysis as early as the deciduous dentition phase.
