Ortho-Cast M-Series Buccal Tubes for Upper First Molars by Dentaurum, Germany
These tubes are designed for the upper first molars and are used in orthodontic treatments according to the MBT system (with a maximum archwire size of 0.022”). A -14° torque allows for lingual root positioning, helping maintain proper anchorage and occlusal relationships. The +10° distal offset means the entry slot is angled to tip the crown distally, aiding in proper tooth alignment within the arch.
The mesial hook allows for attachment of elastics, power chains, or other auxiliaries.
The tube is manufactured as a one-piece unit using MIM (Metal Injection Molding) technology. It is non-convertible, meaning it cannot be opened into a bracket slot, which ensures strength and long-term durability.
It features large and clearly visible laser marking at the base, according to the FDI system.

Clinical Use and Considerations:
Commonly used on upper first molars, which serve as a critical anchorage unit in orthodontic treatment.
The -14° torque helps control root position, especially for achieving Class I molar relationships.
The +10° distal offset supports correct crown inclination and proper alignment of the arch and posterior teeth.
Mesial hooks are often used to attach elastics (e.g., in Class II correction).
Ideal for orthodontists working with the MBT system, 0.022” slot, and direct bonding technique.
