The Revolutionary
Self-Ligating Bracket System


“I’ve found with the decreased slot depth of the passive self-ligating H4 bracket from OC, along with the tightened slot tolerances, plus my “active early” case management strategies, that I’m saving approximately 4 months of treatment , over what I was doing with my previous PSL bracket. I still want a beautiful esthetic based treatment with great occlusion.”

Stunning Smiles in Less Time

Reduced Treatment Time

The tighter tolerances and reduced slot depth on the H4 system increase your control and reduce your overall treatment time.


Less Chair Time

The H4 SL systems means less wires, fewer wire changes, and significantly reduced wire bending.


Simple to Learn

H4 is a single prescription system meaning simplified processes for you and your team.

OC H4 Features and Benefits

The H4 System delivers consistent results using the most revolutionary self-ligating bracket technology. OC’s unique manufacturing process ensures that H4 provides the tightest tolerances in the industry at +/- .001 versus +/- .003, which is 3x more accurate than our competitors. Add in a reduced slot depth of .026 and you have the tools you need to finish with the best, delivering stunning smiles in significantly shorter treatment time.



Integrated Hooks

An available option on the 3’s, 4’s and 5’s for your convenience at no extra charge.


Smooth, Rounded Edges

Ensures that your patients have the most comfortable experience.


Unique Door Design

The unique sliding door creates a fourth wall for improved 3-4 point rotational and torque control.


.026 Precision Slot Depth

The reduced slot depth provides a tighter pairing between the wire and the bracket leading to earlier engagement, improved torque, and better control.


Large Under Tie-Wing Clearance

Supports early elastics, ligatures, metal ligatures, and power chain.


Base Lock Plus

One piece base/bracket creates an optimum pad-to-tooth fit and bond strength meaning fewer broken brackets and fewer debonding issues.

“I have been using a passive self ligation system of braces since 2002. I switched to the H4 PSL system in 2013. I have treated to completion well over 1,500 patients using this system. Because the H4 system has significantly better torque control than the previously used system, I am achieving more consistent results. The H4 system has made me more confident in promising wide beautiful smiles without extractions to patients who have severe problems with crowding and or occulsion. The H4 system is continuing to evolve and these new modifications are making it perform better and better.”

The OC H4 Difference

The H4 System is truly unique and offers a level of precision and control that is currently unmatched. This is achieved through OC’s meticulous metal injection molding manufacturing process. The outcome is a highly refined bracket for the exacting orthodontist who excels at finishing great smiles.



Reduced Slot Depth Means
Increased Control

  • With H4 you benefit from a slot depth of .026 vs the traditional PSL slot depth of .028

  • A precise bracket to wire coupling giving you improved rotational control, more accurate torque expression and predictable finishes

  • As opposed to the traditional 6 archwire sequence, H4 cases use only 4 wires: .014 TA, .018 x .018 UTA, .020 x .020 TA, .020 x .020 Beta


Tighter Tolerances Ensure
Predictable Finishes

  • 3x tighter tolerances than the industry
  • Exclusive door engineering creates a solid fourth wall for improved control
  • Our patent pending door eliminates common clip malfunctions found in other SL bracket systems
  • Catches a couple up to 57% sooner, providing you control even earlier
  • End Result: Predictable and exceptional finishes faster

OC H4™ Archwire Selection

We offer you a variety of archwires which complement the H4 bracket and deliver the torque and control you need. The Pitts archwires have been meticulously designed to reduce extractions while achieving torsion even earlier meaning you can finish your cases faster.
