Abstract
Background: Treatment of skeletal Class III malocclusion in growing patient with an anterior crossbite and open bite is challenging due to unpredictable results and potentially unfavorable growth. Growth modification in adult patients is not an alternative approach. Objective: Case report of a patient with Class III malocclusion in adult and anterior crossbite and open bite was treated with combine fixed appliances and orthognatic surgery. Treatment procedure: Treatment of anterior cross bite and open bite was completed in two phases. The first phase was to correct the dental alignment align and arch coordination with fixed orthodontic appliance. The second phase was to correct the skeletal discrepancy with orthognatic surgery. Conclusions: Orthognatic surgery is a good approach in treating anterior cross bite and open bite relating to skeletal problems in adult period. Changes in profile and occlusion were very obvious.
Highlights
Class III malocclusion is easy to identify but often quite difficult to treat
There are several treatment modalities that can be considered in treating a young Class III patient in late deciduous or mixed dentition, which includes the following: inclined bite plane, exercising with tongue blades, enameloplasty of the deciduous canine, removable plate to expand the maxillary dental arch or to proclined the upper teeth, functional regulator III from Professor Fraenkel, chin cup, and facial protraction mask
The chief complaint was that her lower jaw was too far forward, crocked teeth in the upper jaw and anterior open bite causing eating difficulty
Summary
Class III malocclusion is easy to identify but often quite difficult to treat. This type of malocclusion can be recognized, by dental specialist and by lay person. There are several treatment modalities that can be considered in treating a young Class III patient in late deciduous or mixed dentition, which includes the following: inclined bite plane, exercising with tongue blades, enameloplasty of the deciduous canine, removable plate to expand the maxillary dental arch or to proclined the upper teeth, functional regulator III from Professor Fraenkel, chin cup, and facial protraction mask (with or without RPE). These treatment options have their own indication and benefits that need to be considered before used [2] [4] [8]
