Frankel functional regulator Devpd by Rolf Frankel

Also called oral gymnastic appliance

It has two main treatment effects

1. It serves as a template against which the cranio facial muscle function

2. The appliance removes muscle forces in labial and buccal areas that restricts skeletal growth thereby providing an environment which enables skeletal growth



The following are effects of frankel appliance

Increase in saggital and transverse intra oral space

Increase in vertical space where appliance is kept free from posterior teeth

Mandibular protraction

Muscle function adaptation the pads and shield massage the blood vessels increase circulation

Shields loosen up the tight muscles and improve muscle tone

Frankels exercises or oral gymnastics

1. lips closed at all times

2. swallowing speaking etc becomes exercise while using the appliance


Types of frankel appliance

FR2 :Class2 division 1&2

FR3 :class3

FR4 :Open bite and bimaxillary protrusion

FR5 :They are functional regulator which incorporate head gear indicated in long face patients having a high mandibular plane angle and vertical maxillary excess



Activators induces musculo skeletal adaptation by introducing a new pattern of mandibular closure

The appliance loosely fits in the mouth the pt has to move the mandible forward to engage the appliance this result in stretching of elevator muscles of mastication which starts contracting thereby setting up a myotactic reflex

This generates kinetic energy that cause

Prevention of further forward growth of the maxillary dento alveolar process

Movt of maxillary dento alveolar process distally

Reciprocal forward force on the mandible force is generated while sleeping and swallowing
