Adjuncts and Accessory Appliances
These next appliances help with movements the brackets alone can’t accomplish. These tend to be more case specific and are used in conjunction, or at the same time, as the braces. They may be found in the roof of the mouth as in the case of an expander, habit appliance, or bite plate, OR, they may be external to the mouth as in the case of the headgear or the facemask. They may be utilized for certain types of tooth movement or for growth modification where applicable in a growing child.
A facemask is an orthopedic or growth modifying appliance. It’s used to make changes in jaw growth for kids whose upper jaws are lagging behind their upper jaws causing an underbite (what we call a class III problem). It’s most effective in children who have growing left to do. This appliance is used in conjunction with an expander. This is one problem that must be screened for and corrected early because it’s effectiveness decreases with age.
