Spring Retainer

The Spring Retainer is an aligner that serves dual functions. First, it is an appliance for active orthodontic treatment that is effective in aligning crowded teeth. Secondly, it serves as a post-treatment retainer, to keep the aligned teeth in place.

Made by constructing a model of your teeth, the spring retainer includes a wire spring that gives the appliance/retainer the flexibility to fit properly. You may experience some soreness while wearing the retainer – this means that the retainer is working. Remove the retainer to eat, drink and clean it.


The E-Arch is a fixed appliance that is used to widen the upper or lower jaw to make room for permanent teeth. It consists of a pin, an open coil spring and tube that are attached to the molars by two bands. The open coil spring is used to activate the pin and tube. This activation begins immediately when inserted into the mouth. The force of the spring combined with the amount of time the appliance is worn by the patient determines the amount of expansion.


TADs are miniscrew anchors which are inserted into specific places in the mouth to be used as a fixed point from which teeth can move. Before TADs, orthodontists who wanted to move some teeth while keeping others still, or to achieve orthodontic movement in a mouth with missing teeth, had to rely on headgear for their fixed point. But TADs now provide an option for that fixed point that is smaller, more discrete, more efficient and requires significantly less work for the patient.


The Herbst appliance prevents the lower jaw from moving backward but allows opening and closing movement to occur easily. At first, your mouth will feel unusually full, and speaking will be awkward. But if you practice reading aloud, your ordinary speech will return quickly. You may also notice more saliva than normal, but this will decrease as you become accustomed to the appliance. Patients will not have any problems learning to chew their food with their lower jaw in this new position. As with all kinds of braces, patients with Herbst appliances need to be careful about what they eat. Your Herbst appliance will be checked and adjusted at your appointments. If, sometimes between appointments, you develop some sore areas on the inside of your cheeks, please do not try to adjust the appliance yourself. Call for an appointment so that the necessary adjustments can be made.


The Forsus appliance is used in order to help move the upper molars back while moving the lower arch forward. Composed of a spring coil rod, the appliance is used while a patient is currently wearing braces. It runs from the upper first molar band down to the lower archwire.

The Forsus uses constant pressure and force to gradually move your jaws and teeth into proper alignment. You don’t have to do anything! It works while you are doing any activity – day or night! You may notice some discomfort initially, so we recommend a soft food diet for the first few days after the appliance is placed. It is important to keep the appliance clean; you may do this by carefully brushing the coil and other metal pieces of the appliance. Also, we recommend that patients not open their mouths very wide, as the appliance may come apart.

If your Forsus appliance breaks, please contact our office immediately to schedule a repair appointment.
