The Transpalatal Arch helps maintain obtained expansion or tipping of permanent molars treated with an expansion appliance, removable or fixed. The appliance can be fabricated as a removable option, for patients under fixed orthodontic treatment and for those who need important teeth movement, the removable transpalatal arch provides additional anchorage. 

Fabrication requirements 

- Upper or lower stone model

- Bands Supplied in Situ

- Option for Post fitted Lab Supplied Bands

The Unilateral band & Loop Space Maintainer is used after premature loss of a primary molar in order to maintain the space for a premolar. It is wire fitted with its ends soldered to the fitted band and the other end resting on the distal surface of a premolar or cuspid.

- Upper or lower stone model

- Band Supplied in Situ 

- Option for a Post fitted Lab Supplied Band

Fixed rapid palatal expanders enable separation of the median suture by creating less teeth tipping movement than slow expansion appliances. These expanders are perfect for patients who have less motivation and therefor can be less complaint with treatment and whose teeth require greater and faster expansion. To obtain massive movement, the central expansion screw must be activated twice every day at a rate of 0.025mm, mornings and evenings. 

The screw that activates the Hyrax is durable because it needs to be firmly fitted on the lingual part of the bands, which are previously adjusted to the first permanent molars and premolars. Alternatively popular modified versions using only 1st Molar bands with rests on the 1st premolars, are used for more predictable paths of insertion.

- Wax bite in C.O

The Rickanator is a fixed or fixed/removable appliance comprised of an acrylic anterior inclined plane. The Wearing of the appliance provides mandibular advancement, which corrects a Class II case to a skeletal Class I. If used  in conjunction with fixed orthodontic brackets, it will enable simultaneous correction of dental and skeletal alignments. Because of the anterior inclined plane, there is no contact between the upper and lower posterior teeth, which enables the occlusion to open up. By adding occlusal rests to the first and second premolars you can strengthen the appliance lowering risks of breakage. 

Because patients are not able to remove their appliances, dentists must monitor the progression of mandibular advancement and clean the soft tissues on a regular basis.
