[Incisors crossbite correction with spring inclined plane appliance: principles and procedures].
The spring inclined plane is one of the removable appliances that can be used to correct incisors crossbite which is designed for the early treatment period. In order to prevent skeletal malocclusion and reestablish proper muscle balance. The appliance is very simple which composes of clasps on the first molar both sides and spring 0.9 millimetre diameter. This spring was bended as an inclined plane above the lower incisors. The force from this spring will push upper incisors anteriorly. The spring inclined plane is very effective in mixed dentition. Nevertheless this spring is appropriate to use in the patient who can not wear the removeable orthodontic appliance in the upper jaw.
