Begg’s appliance:
This was the early fixed braces systems that came to existence. It was developed by Dr.Raymond Begg. The appliance used light forces with the help of round thin wires to move teeth. Begg’s bracket design allowed teeth to freely tip mesially and distally as well as lingually and labially. The appliance works by tipping the teeth to the desired position and then followed by uprighting of the tooth. This type of braces is less used frequently with the advent of the straight wire system.
Advantages:
Light elastic forces are used to move teeth.
Rapid tooth movement the bracket design allows for free movement of the teeth.
All anchorage requirements can be established intra-orally without headgear, without the need for any ancillary appliances.
Less costly than other appliance systems.
Disadvantages:
The system requires the use of auxiliaries such as torqueing auxiliaries and uprighting springs, which increase chair side time at appointments.
Since the teeth are free to move, there is a chance that the tooth would tip more than what is required.
Uprighting the tooth and establishing the required torque is a challenging process.
