Selective engagement allows you to choose the ideal
balance between low friction and interactive control for
each treatment phase. Early in treatment, with smaller
dimension round and rectangular wires, T3 bracket clips
are passive, allowing teeth to unravel and level freely and
quickly. As treatment progresses into larger rectangular
wires, T3’s unique clip actively engages the wire, provid-
ing three-dimensional control for precision detailing.
F i n i s h i n c o n t r o l
Friction in conventionally ligated brackets can be up to 600X that of self ligation systems. 1,2,3
T3’s selective engagement clip produces an ultra low friction slot with early treatment wires.
Passive self ligating brackets never fully engage finishing wires, leading to frustrating detailing challenges at the end of treatment.
As wire dimensions increase, T3’s selective engagement clip seats the wire into the bottom of the slot, increasing control and accuracy.

How much higher are the in/out dimensions? In-Ovation R* Damon 3MX*
T3’s coordinated in/outs keep the arch wire in harmony
with the patient’s natural arch form, critical to treating
cases successfully. Very low in/out heights keep the arch
wire as close as possible to the surface of the tooth,
ensuring targeted control of tooth movement. Low in/outs
also allow for lower overall bracket height, providing
more patient comfort and reducing unwanted debonds.

T3 clip access is front and center on the facial surface of the bracket. Opening and closing require only gentle rolling forces, comfortable for the patient.
The most reliable opening method for spring clip style brackets, like In-Ovation R*, is from the gingival, and is subject to poor visibility, especially in the posterior or in patients with inflamed gums. Opening requires heavier forces and can be uncom-fortable for patients.
Sliding gate style brackets, like Damon* system brackets, can also require heavier, uncomfortable opening forces, particularly as treatment progresses and bio-debris builds up in the clip mechanisms.
INTERACTIVE SELF L IGATION
Other clip designs have substantial portions of metal on metal
sliding contact, which are prone to calculus and plaque accu-
mulation. This bio-debris buildup can make the clips frustrating to
open and leads to uncomfortable wire changes for patients.

T3 brackets are available in a Roth system, a McLaughlin, Bennett, Trevisi system, and a Straight Wire system. The American Orthodon-tics versions of these systems are not claimed to be a duplication of any other, nor does American Orthodontics imply that they are endorsed in any way by Drs. Roth, McLaughlin, Bennett, or Trevisi.
T3 brackets are available with high and low torque options.Hooks are available on cuspids.

B o n d i n gT3 brackets should be bonded with the spring clip in the open position. This minimizes any chance of adhesive interfering with the operation of the clip. Clips should be closed when indirect bonding.
Use traditional direct bond adhe-sive when bonding T3 brackets. The T3 one piece design with microetched Quadra GripTM base has proven to provide excellent bond strength.4
After the adhesive has cured, install arch wires and close the spring clip. The clip should only be opened and closed using the specially designed T3 bracket instrument.
To open the clip, insert the instrument in the labial opening and gently rotate the instrument between the thumb and forefinger toward the gingival. When the clip is open, there is resistance to further opening. Do not attempt to over-rotate the clip.
