The "Roth" in the name refers to the Roth prescription, which is a popular orthodontic bracket system that uses specific measurements and angles to help align teeth. The "convertible" designation means that the buccal tube can be used with either a convertible or a non-convertible headgear, depending on the needs of the patient.
The double buccal tube means that the appliance has two openings or slots for attaching archwires. This allows for greater control and flexibility in the movement of the teeth.
