Standard Orthodontic Expansion Appliances are made by using Slow expansion screw (Jack’s screw). They are very effective appliances for dental expansion treatment of adults and children. The treatment length is relatively quick assuming the patient is compliant with the appliance. There are many types of Expansion appliances, most aim to achieve jaw widening, some of the appliances can also move individual groups of teeth. Demanding on purpose and treatment requirement, we can design the kind of expansions for the desired movements.

The bluegrass appliance a tongue thrust/thumb sucking habit breaking appliance. This appliance has special wire that is connected to molars that extends forward towards the roof of mouth behind front teeth. There is an acrylic or plastic “wheel” that rests against the roof of mouth. It is used to stop thump sucking and or tongue thrusting by spinning the wheel instead of performing the “habit”.

Thumb Sucking Habit breaking Devices or habit breakers has become a very popular device nowadays. These are designed to create an uncomfortable environment and disrupt the patient from placing the thumb into the palate. This habit is disruptive to the development of dental arches and the position of teeth during childhood growth and will displace the Dental arches pushing teeth away from the natural position leaving problems such as Anterior open bites and spacing of the front teeth. Children who develop anterior open bites due to thumb sucking will require extensive orthodontic treatment to correct to malocclusion. This is a very effective and cost effective appliance to prevent developmental issues with the thumb sucking patient.

Same concept as an anterior biteplate except it comes between upper and lower posterior teeth, causing an amount of space to be available between the upper and lower anterior teeth. This in turn would allow the anterior teeth to erupt. A posterior biteplate is used to correct an anterior open bite It is often used with other appliances such as an expander. It does so by allowing the anterior teeth to erupt (extrude) while preventing the posterior teeth from erupting (some relative intrusion of the posterior teeth).May also be used along with fixed appliances to allow the trapped tooth to come into occlusion.

The pendulum appliance is used to correct class II malocclusions by moving back the upper molars. It allows the orthodontist to retract the upper front teeth in the proper position.The pendulum appliance consist 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 pendex appliance is a pendulum appliance that uses an expansion screw to widen the upper palate and pushes the upper teeth back correcting class II malocclusions and the patient’s bite.The pendex appliance consist of a plastic “button” that touches the roof of the mouth and resilient wire springs that act in a broad swinging arch to move the molars back. 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 moths.

The foundation of early orthopaedic treatments patient with tooth size/arch size discrepancy problems is the bonded rapid maxillary expansion appliance. A number of articles have appeared in the literature that have described various types of bonded accrelic splint appliance that are used either alone as expanders or in combination with other appliances.The accrelic splint expander widens the maxilla by separating the mid palatal sature and activating the circummaxillary sature systems. In young patients the effect of the appliance aprimarly is orthopedic in nature.The bonded expander not only widens the transverse dimension, but it produces changes in the vertical and anturoposterior dimension as well. The posterior occlusion coverage of the acrylic act as a posterior bite block inhibiting the eruption of the poster teeth during treatment and making possible the use of the appliance in patients with long lower anterior facial height. The acrylic occlusion coverage also opens the bite posterily, facilitating the correction of the anterior cross bites.

This is an appliance choice for poor co-operating patients. It can be given along with the fixed appliance where we can use as an anchorage unit along with TPA.

It is a Slow Orthodontic Expansion Appliances made by using Coffin spring for dental expansion treatment of adults and children. With this we can control the expansion direction by activating the Coffin spring.

Standard Begg’s design includes a wire arch (labial bow) with adjustment loops at canines or second premolar region and closely contoured to the second molars. Small support wires can be used between the canines, if needed. Begg’s retainer is also a very popular form of post treatment orthodontic retainer. The custom made retainer is designed to hold the teeth in their final position after fixed orthodontic brackets and arch wires have been removed. It is the best appliance to close the band space in those cases where the last molar is not present.

An anterior biteplate is an appliance that would fit snuggly to the palate of the patient and disarticulates the front teeth. The concept of this appliance is to separate the posterior teeth to help posteriors to supra irrupt in deep bite cases or to correct posterior cross bite along with fixed appliances,The appliance is retained in the mouth with the help of the clasps found in the appliance. Adams clasps around the molars or ball clasps in the space between teeth are most commonly used for this purpose of retention.
