Functional Appliances


Orthotek specializes in a variety of functional appliances that are fabricated with the highest quality expansion screws, wire and acrylic available.  Featured below are some of the most common functional appliances used.  We can construct any variation of design that yo require.  Please use our prescription sheets to illustrate and describe the complete details of your design. 
The pictures are for illustration purposes only. Actual design may vary.

   Pendulum

The pendulum appliance can be used to move the upper molars backward in an effort to correct the bite and make room for the front teeth.
 

Expander 3-way-Upper
           

Used to expand the upper arch in 3 directions, the front forward and the back transversely. This appliance achieves arch expansion to eliminate crowding and an optimal relationship to the lower jaw.                    
 

Schwartz-Upper


This transverse appliance is recommended when there is an arch width deficiency or a bilateral cross bite and also to help eliminate anterior crowding. An expansion screw is used for transverse expansion.



  Schwartz-Lower

Helps to avoid any interference on cuspids of the molars and premolars. One expansion screw for lateral development.


   Twin Block

It is made up of two components, an upper and lower plate, which works together to posture the lower jaw forward.  This frees up the “locked-in” lower jaw and encourages it to grow to its full potential.  The upper (and sometimes lower) plate may also have an expansion screw to widen the arch.


  Schwartz w/ Labial Bow Lower

The basic Schwartz appliance is comprised of an expansion screw, clasping for retention, a labial bow and acrylic.


  Is very versatile.  Used to provide space to correct crowding by distalizing molars. 

Sagittal-Upper

The sagittal appliance is designed to achieve anterior development and/or distillation of the posterior segments.  An acrylic body with posterior bite planes and and two sagittal screws expand in an anterior/posterior direction.

 

These appliances open in all directions distalizing molars and making the arch wider.


Sagittal-Lower

Exerts force to move teeth in a sagittal direction


   

Bionator I-
To Open Bite   
            
            
An acrylic cap contacting incisors and posterior acrylic relief allows posterior eruption to produce the bite opening.

   

Bionator II
-To Close Bite

Acrylic coverage of posterior teeth prevents further eruption and allows anterior open to close.


   

Bionator III
-To Maintain Bite

An incisal cap and posterior occlusal acrylic stabilizes all teeth, allowing no vertical changes, thus maintaining the bite.


   

Corrector 2

For expandable movement between the anterior segment and the posterior segments. A method of correcting a Class II Division 1 malocclusion. The appliance is expanded in stages to maximize the utilization of corrective lower jaw movements which result from the anchoring of the orthopedic appliance in the patient's upper mouth.



   

Herbst Dischinger Cantilever

The removable Herbst postures the mandible forward into a “Class III” relationship. The hinging motion permits opening and closing movements. The appliance may be adjusted for additional advancement as required.

 


   

Hersbt

Herbst utilizes wire-reinforced acrylic splints and a pair of retention hinges to allow the mouth to open while limiting the posterior displacement of the mandible.  This fixed functional appliance ensures patient cooperation and predictable results.
