At Coral Orthodontics, Dr. Prathima Adusumilli, Orthodontist chooses specialty appliances to treat different malocclusions in children, teens and adults.

Active appliances such as: Expanders, Head gears, Face mask, Chin cups, Lip bumpers, Active plates like Hawley appliance, Schwartz expansion, Space regainers. Anterior spring alligners, Vacuum formed appliances.

Passive appliances such as: Space maintainers, Bite planes. Retainers, Occlusal splints, Posterior bite blocks.

Functional appliances such as: Herbst, Bionator, Frankel, Forsus, Jasper Jumper.

Rapid maxillary expander
This appliance is used to widen (expand) a narrow upper jaw. The plastic over the surfaces of the back teeth provide excellent control of vertical upper jaw growth in patients that have anterior open bites. Hooks can be added for protraction and correction of developing Class III malocclusions (underbites).

Frankel appliance
This appliance is a removable functional appliance. These appliances are of European origin that have been clinically proven to correct skeletal (jaw related) problems associated with smaller or deficient size of the lower jaw (mandible). This appliance is typically used in the mixed dentition and may be in place for 12 to 15 months to be effective. It is worn all the time except for activities, eating and brushing.

Anterior tongue crib
This appliance is often used when there is an anterior tongue thrust or in some cases where a persistent digit (thumb sucking or finger sucking) habit persists. It is generally fixed to the teeth and provides a physical barrier to keep the tongue from posturing between the anterior teeth or as a reminder to keep the thumb or finger out of the mouth.

Nance space maintainer (upper) and mandibular (lower) holding arch
These appliances are space maintaining appliances used in the upper (maxillary) and lower (mandibular) arches. They are fixed to the permanent first molars with the purpose of maintaining space during the transitional tooth stage. They are very effective appliances to be used when there is early loss of the second deciduous molars or in cases where maintaining some space posteriorly will allow moderate crowding to be corrected non-extraction.

Twin Block
This appliance is a removable functional appliance used to correct moderate to severe lower jaw deficiencies (mandibular retrognathia). It is the newest of the removable functional appliances having been developed in the early 1990s. It has been proven effective by scores of clinical studies as an orthopedic appliance. Its advantage over some of the other removable functional appliances is that speech and function are less affected because of the independent upper and lower components.

Retainers
These appliances are very important and need to be worn at the completion of orthodontic treatment. Studies clearly show that teeth will continue to shift throughout life with or without the presence of wisdom teeth. Consequently after a period of full time wear these appliances are worn on a night time basis indefinitely.

Schwarz expander
This appliance is used to upright mandibular posterior (lower back) teeth that have tipped lingually due to a very constricted upper jaw (maxilla). Once the teeth are uprighted, the maxilla can be widened (expanded) more effectively and an improved functional relationship achieved.
________________________________________

Pendex appliance
This appliance is a type of palatal expanders that has the additional benefit of moving the upper back teeth distally to correct a Class II posterior occlusion. This can also create additional arch length to correct moderate crowding. In either case, the removal of maxillary teeth has been avoided in many cases where extractions were necessary in the past.

Elastics or Rubber bands
This auxiliary is often used to correct many problems involving tooth movement. It can be used in many different configurations. They are typically worn full time to be effective since less than hundred percent wear has been clinically shown to be ineffective.

MARA appliance (Mandibular Anterior Repositioning Appliance)
This appliance belongs to the category called fixed functional appliances. Although they have been reported in the literature for many years, they have shown increasing popularity because they eliminate some of the cooperation problems associated with the removable functional appliances. They are often in the mouth for 12 to 15 months on a 24/7 basis. Maxillary expansion can often be accomplished at the same time. This appliance works by advancement elbows keeping mandible postured forward on a continual basis.

Anterior Bite Plane
This appliance is often used either by itself or in combination with full fixed braces to help correct excessive vertical overbites (deep bites). It works by keeping the posterior teeth apart from the plastic (acrylic) anteriorly behind the maxillary incisors. It is typically worn for about six months with full fixed appliances, allowing much faster correction of the deep bite.
