Correlations between temporary teeth and functional treatment in mixed dentition – case presentation

Objectives. Orthodontic treatment intends to create a harmony between dental, muscular and osseous components. The purpose of this case presentation was to emphasize consequences of early loss of temporary teeth on dental-maxillary complex development. Material and methods. 10 years old patient with dental movements following the early extraction of temporary teeth. The patient has habitual oral breathing associated with lower lip interposition. Results. The functional treatment with twin-block appliance was chosen, taking into account the age-specific growth potential. Discussions. Premature extraction of temporary teeth engenders lee-way-space loss, significant shortening and transverse constriction of the dental arch, elements aggravated by dysfunctions and parafunctions. Conclusion. The early extractions performed during the growth period, through the associated dental migrations, determine growth changes with consequences on the functionality of the dento-maxillary apparatus.
