Abstract

Abstract: There are many common dental malocclusions seen in the mixed dentition, such as premature loss of, or retained, deciduous teeth, submerged molars, supernumerary teeth, midline diastema, crossbites, increased overjet, open bites, ectopic eruptions and crowding. In properly selected cases, like dental anterior crossbites or unerupted incisors, interceptive orthodontic treatment not only improves function and aesthetics, but also achieves a relatively stable outcome, even after the removal of the appliance. A removable appliance can be a mode of interceptive orthodontic treatment. The success of the interceptive treatment using a removable appliance, however, depends upon patient compliance. In this regard, use of a sectional fixed appliance is gaining in popularity. This paper discusses four case scenarios of malocclusion in the mixed dentition managed using sectional fixed therapy.

CPD/Clinical Relevance: The sectional fixed appliance is versatile, easy to use and well tolerated by patients. When used correctly, it gives a more controlled approach to tooth movement in all three dimensions and a more predictable outcome.

Article

Common dental malocclusions seen in the mixed dentition include premature loss/over-retained deciduous teeth, submerged molars, supernumerary teeth, midline diastema, crossbites, increased overjet, open bites, ectopic eruptions and crowding.1 The available scientific data suggest that malocclusions have negative effects on oral health-related quality of life, predominantly in the dimensions of emotional and social wellbeing.2 Interceptive treatment is thus recommended in order to reduce the severity of a developing malocclusion. In properly selected cases, like dental anterior crossbites or unerupted incisors, interceptive orthodontic treatment not only improves function and aesthetics, but also achieves a relatively stable outcome, even after the removal of the appliance.3

Although a comprehensive orthodontic finish without a second phase of treatment in the permanent dentition is not obtained in all cases, carefully planned interceptive treatment may help to reduce further orthodontic treatment.4
