Cannon Ultra II
Dr. Cannon’s 40 years of clinical experience using both frictionless techniques and the straightwire system have lead to the development of the Cannon Ultra II™ bracket system. Combining the best of both worlds, the Cannon Ultra II™ offers simplicity, versatility, and universal adaptability, leading to high quality results in an astonishingly short time. The biological and biomechanical background of the Cannon Ultra II™ system offers individualized treatment for your patients based on the skeletal pattern. Straightforward appliance construction and the easiest possible elastic ligation system results in reduced chair time and maximum patient comfort. The Cannon Ultra II, carries the concept of the programmed edgewise bracket to its next level.
Faster treatment time through Wing Slot utilization
The Cannon Ultra II™ bracket system features an innovative Wing Slot that improves and simplifies edgewise mechanics. In addition, the Cannon Ultra II™ bracket is equipped with a Low Friction edgewise slot, as well as a hook on every bracket to accommodate elastics. This represents a major step forward in making rotational corrections, bite opening, establishing differential resistance, and establishing the necessary anchorage for en masse retraction of the anterior teeth more efficient and less complicated.
Design of the Wing Slot
The Wing Slot is a gingival, vertical opening, Low Friction slot, even with elastomeric ties. It is unique in that an archwire can be held securely in place in the Wing Slot utilizing the same ligating elements as used to secure an archwire in the edgewise slot. Accommodates all ligating techniques.
Low Friction Edgewise Slot

Allows for up to 18 degrees of tip of the tooth before adverse forces affect adjacent teeth.
This slot is unique in that the vertical sides are unequal in height. This allows for the ligating element to position the archwire in the bottom of the slot, affording better rotational control with an archwire as small as .016. As the archwire increases in size, more friction is developed between the ligating element and the archwire.
When maximum friction is desired, the ligating element is not positioned in the facial channels of the bracket, but is placed around the bracket so that the ligating element exerts pressure directly against the archwire.
How it Works.
The Cannon Ultra II Bracket System is the first bracket system that enables orthodontists to easily treat mild to moderate apical base class II and III cases. This is accomplished by utilizing the wing slot, which opens to the gingival and allows for dental compensation. The archwire is held securely in the wing slot by utilizing the same elements as with the edgewise slot, "O" ring, power chain and steel ligature tie. There is also a pre-adjusted edgewise slot for the treatment of apical base class I cases. Bodily en masse retraction of the anterior teeth can be easily accomplished in extraction cases by utilizing an archwire in both slots simultaneously. When utilizing a .018 steel archwire in the wing slot with bilateral 25 degree "V" bends in the middle of the extractions sites in the conjunction with a .018 x .025 nickel titanium archwire in the pre-adjusted slot, proper movement-to-force ratio is established so as to bodily retract the anterior teeth and enhance anchorage so that no external anchorage is required.
