woodside.jpgWoodside Activator

The Woodside Activator is utilized to correct Class II malocclusions, where advancement of the mandible and development of the mandibular posterior segment is required.

This appliance has a labial bow which extends posteriorly to disengage the buccinator muscles, and two molar springs to aid in the dislodging of the appliance.

The Open-Face Activator is utilized for arch expansions in Class I and Class II division malocclusions. The lower posterior teeth are free to erupt while the labial bow removes restriction from the buccinator muscles and allows for arch expansion. Unlike other activators which are more bulky, the Open-Face Activator is characterized by a slim profile.

 


 

BionatorI.jpgBionator I

Holds the mandible forward so it will grow and has plastic over the back teeth keeping them from growing so the front teeth can catch up. This bionator is designed to aid in the correction of Class II malocclusions and the reduction of the anterior open bite. The latter is achieved by keeping the acrylic coverage over the occlusal surfaces of the posterior teeth. An expansion screw is used to maintaina tight fit of the appliance.

FrankelI.jpgFränkel I


The Fränkel I is utilized to promote transverse arch development both dentally and skeletally. This is acomplished by the vestibular shields removing extrenal muscle pressure from both the maxillary and mandibular arches. The appliance is also effective for interruption of abnormal mentalis function. Since there is an absence of dental contact, the appliance will also promote facial development.

The Primary thrust of the Fränkel II will also accomplish transverse and vertical development of both the maxilary and mandibular arches. The construction of this appliance allows for subsequent additional advancement of the mandibular portion of the appliance, thus largely eliminating the necessity for replacement appliances as mandibular growth occurs.

 

 

FrankelIII.jpgFränkel III


This appliance is used to aid in the correction of Class III malocclusions. This can be achieved by retarding further development of the mandible while simultaneously allowing for the development of the maxilla to it's fullest growth potential. It is also effective in conjunction with other treatment modalities such as the Adaptable Class III Mask.

 

 

 

FrankelV.jpgFränkel IV


The Fränkel IV is used exclusively in Class I malocclusions where skeletal open bite, arch with deficiency, or abnormal muscle function are present. Wire or acrylic stops are placed on posterior teeth allowing anterior tooth eruption. The vestibular shields will aid arch expansion muscle stimulation. Please note that the Fränkel IV will not sustain any advancement or retrusion of the mandible.

 

 

FrankeV.jpgFränkel V


The Fränkel V is a modification of the Fränkel II and as such is intended for Class II malocclusions, particularly in cases where an increase in vertical dimension is undesirable. The Fränkel V is often used in conjunction with traction devices.

 

 

clark.jpgClark Twin Block Appliance


The Twin Block Technique was developed as  a new principle in functional orthopaedics. Twin Blocks use the forces of occlusion as the functional mechanism to correct the malocclusion.Twin Blocks are worn 24 hours per day. This means that the patient eats with the appliances in the mouth and the forces of mastication are harnessed to maximize the functional response to the treatment.

Cooperation is excellent with Twin Blocks because the appliance is not removed for two to three days after it is fitted. There are no unesthetic check pads or lip pads, and no uncomfortable lingual extensions or anterior wires. Twin Blocks can be modified to treat a wide variety of malocclusions to achieve sagittal and vertical correction of Class II division 1 and Class II division 2, and Class III malocclusions. Twin Blocks are also indicated in teatment of temporomandibluar joint dysfunction.

The basic appliances are separate upper and lower plates. The upper plate includes an expansion screw for lateral development and occusal pads to cover the molars.The lower plate includes occlusal pads to cover the lower bi-cuspids. These plates interface at 70ˆ angles and posture the mandible in a forward position.

Deviations from standard design are :
• Twin Block Sagittal Design
• Twin Block Schwarz & Jackson (to expand)
• Twin Block Quad Helix (arch development)
• Twin Block Crozat
• Fixed Twin Blocks, Magnetic Twin Blocks, and Sagittal Twin Blocks for TM Joint therapy.
