Aim:

To evaluate the prevalence of anterior crossbite and to verify the effectiveness of the orthodontic appliance Inclined Plane in the correction of this malocclusion.

Methods:

The clinical examination was performed 702 children in the deciduous or mixed dentition of 7 schools and in those found the anterior crossbite was performed treatment with fixed Inclined Plane.

Results:

The prevalence of the anterior crossbite was 2.14%, characterizing 15 of the 702 children evaluated, of which 60% were female and 40% male, all of which were dental crossbites. Only 12 accepted the treatment with an average duration of 4.4 weeks.

Conclusion:

The prevalence of anterior crossbite was 2.14%. The inclined plane proved to be a viable and effective therapy in the correction of anterior crossbite. It is one of the options of the orthodontic treatment in patients in the deciduous or mixed dentition, propitiating greater possibility of dentoskeletal development, since the malocclusion is corrected. However this method needs to be correctly indicated and its execution technique rigorously followed
