“…The need for early orthodontic treatment and the benefits of one-phase versus two-phase treatment has been broadly discussed. [ 29 30 31 ] It is our belief that the need for treatment should depend on the severity of the malocclusion and the effect on the neuromuscular and skeletal system.…”

Introduction:The aims of this study were to establish the prevalence of dental features that indicate a need for early intervention and to ascertain the prevalence of different methods of early treatment among a population of Nigerian children in mixed dentition.Methods:Occlusal relationships were evaluated in 101 children in mixed dentition between the ages of 6 and 12 years who presented at the Orthodontic Unit, Department of Child Dental Health, Lagos University Teaching Hospital over a 2 years period. The need for different modes of early orthodontic treatment was also recorded.Results:Anterior tooth rotations (61.4%) and increased overjet (44.6%) were the most prevalent occlusal anomalies. Others included deep bite (31.7%), reverse overjet (13.9%), and anterior open bite (14.8%). Severe maxillary spacing and crowding were exhibited in 12.0% and 5.0%, respectively. About a third (35.7%) of the subjects presented with crossbite while lip incompetence was observed in 43.6% of the subjects. About 44% of the subjects also presented with various oral habits with digit (15.8%) and lip sucking (9.9%) being the most prevalent. Subjects were recommended for treatment with 2 by 4 fixed orthodontic appliances (22.3%), habit breakers (20.7%), removable orthodontic appliances (16.5%), and extractions (15.7%).Conclusions:Increased overjet and anterior tooth rotation were the majority of occlusal anomalies seen, which are not only esthetically displeasing but may also cause an increased susceptibility to trauma to these teeth. Treatment options varied from extractions only to the use of appliance therapy.

“…Previous studies have reported that 32-63% of the patients with skeletal Class III malocclusion have a maxillary deficiency or its combination with excessive mandibular growth. [8][9][10] Orthopedic, functional, or orthodontic treatments or combination of these are among the treatment options of Class III cases.…”

“…Early intervention of Class III malocclusion is still one of the most controversial subjects in orthodontics. [10][11][12] The major obstacles to achieve a balanced profile in the cases are additional excessive mandibular growth and genetic pattern. 13 Therefore, some authors claimed that many Class III patients have potential to candidates for orthognathic surgery 3 and they advocated orthognathic surgery for the patients.…”

Skeletal Class III malocclusion is one of the most challenging, complex and difficult problems to treat. Functional orthopedic appliances can produce favorable outcomes during early mixed dentition in cases with Class III malocclusion. The purpose of this case report was to present a successfully treated 8-years-old female patient having skeletal Class III malocclusion due to maxillary retrusion by means of a simple Class III corrector, the bimaxillar prognathism upper plate according to Buño.

ObjectiveThe purpose of this retrospective study was to investigate short-term and long-term skeletodental outcomes of Class III activator treatment.MethodsA Class III activator treatment group (AG) comprised of 22 patients (9 boys, 13 girls) was compared with a Class III control group (CG) comprised of 17 patients (6 boys, 11 girls). The total treatment period was divided into three stages; the initial stage (T1), the post-activator treatment or post-mandibular growth peak stage (T2), and the long-term follow-up stage (T3). Cephalometric changes were evaluated statistically via the Mann-Whitney U-test and the Friedman test.ResultsThe AG exhibited significant increases in the SNA angle, ANB angle, Wits appraisal, A point-N perpendicular, Convexity of A point, and proclination of the maxillary incisors, from T1 to T2. In the long-term follow-up (T1-T3), the AG exhibited significantly greater increases in the ANB angle, Wits appraisal, and Convexity of A point than the CG.ConclusionsFavorable skeletal outcomes induced during the Class III activator treatment period were generally maintained until the long-term follow-up period of the post-mandibular growth peak stage.
