Types of Braces & Appliances
Tongue Thrusting Appliance
Tongue thrusting occurs when the patient presses his or her tongue against the front teeth, usually when swallowing, speaking or resting the tongue. If thrusting is constant, this can cause problems with teeth alignment and must be fixed.
Dr. Bonavoglia prefers to correct tongue thrusting by giving patients a tongue thrusting appliance. This appliance, similar to a mouthguard, is usually worn at night. Other times, a more permanent appliance is prescribed and can be only be adjusted by Dr. Bonavoglia.
Sucking is a natural reflex that relaxes and comforts babies and toddlers. Children usually cease thumb sucking when the permanent front teeth are ready to erupt. Typically, children stop between the ages of 2 and 4 years. Thumb sucking that persists beyond the eruption of primary teeth can cause improper growth of the mouth and misalignment of the teeth. If you notice prolonged and/or vigorous thumb sucking behavior in your child, please talk to your dentist.
One solution to thumb sucking is an appliance called a “fixed palatal crib.” This appliance is put on the child’s upper teeth by an orthodontist. It’s placed behind on the upper teeth on the roof of the mouth. The crib consists of semicircular stainless steel wires that are fastened to molars using steel bands. The stainless steel wires fit behind the child’s upper front teeth, and are barely visible. The crib usually stops the habit of thumb sucking within the first day of use.
The Pendex Appliance is a Pendulum Appliance that uses an expansion screw to widen the upper palate, correcting class II malocclusions and the patient’s bite.
The Pendex Appliance consists of a plastic “button” that touches the roof of the mouth. Within this button, there is a keyhole where you are to place the key and turn it according to your orthodontist’s instructions. This turning will widen the appliance, thus widening your upper palate. Patients usually wear this appliance for 3 to 6 months.
Headgear is often used to correct an excessive overbite. This is done by placing pressure against the upper teeth and jaw, which would hold the teeth in position or help move them into better positions. The severity of the problem determines the length of time headgear needs to be worn. The key to success with your headgear appliance is consistency. Headgear must be worn a certain number of hours per day, and if not, it must be made up the following day.
Headgear should never be worn while playing sports and should also be removed while eating or brushing your teeth.
The Pendulum Appliance is used to correct class II malocclusions by distalizing upper molars. It’s used to correct the patient’s bite on the side of their mouth.
The Pendulum Appliance consists of a plastic “button” that touches the roof of the mouth and resilient wire springs that act in a broad swinging arc to move the molars back. The appliance uses the roof of the mouth as an anchor to move the molars back into their correct positions. Patients usually wear this appliance for 3 to 5 months.
The Nance Appliance is used to prevent upper molars from rotating or moving forward after you’ve worn a headgear or any other appliance to move your molars back. Some patients wear the Nance Appliance while they are awaiting their bicuspids to grow into place.
This appliance is made of two bands that are cemented onto the first molars with a wire that spans the roof of the mouth from one molar to the other. An acrylic pad or “button” covers the wire that touches the roof of your mouth directly behind your front teeth.
Patients should always brush around the bands daily. Do not eat sticky, chewy candy as it can loosen your appliance. If you have any problems with your Nance Appliance, please call our office immediately.
