Intended Use

The Click-It ceramic self-ligating bracket is intended to be used in an orthodontic treatment with the aim of moving teeth.

Device Story

Click-It ceramic self-ligating bracket; used in orthodontic treatment to move teeth via remodeling of mandibular and maxillary bone. Device consists of polycrystalline alumina bracket, two polycrystalline alumina jaws, nickel titanium spring, and two nickel titanium pins. Bonded to buccal and labial tooth surfaces; archwire ligated into bracket slot via self-ligating mechanism, eliminating need for auxiliary elastics or wires. Enables tooth movements including tipping, translation, torque, extrusion, rotation, and intrusion. Operated by orthodontists in clinical settings. Provides sustained pressure on teeth; clinical benefit includes corrective tooth positioning. Designed to fracture safely upon impact to prevent patient harm.

Clinical Evidence

Bench testing only. Comparative performance testing against predicates included shear bond strength (ISO 11405), friction testing, wire escapement, impact/catastrophic disassembly, pull testing, and archwire slot dimensional analysis. Results demonstrated Click-It performs comparably to predicate devices. Biocompatibility testing confirmed compliance with ISO 10993 standards.

### Device Description

The Click-It ceramic self-ligating bracket is intended to be used in an orthodontic treatment with the aim of moving teeth. The basic function is the same as the orthodontic brackets for which substantial equivalence is claimed such that the movement of the tooth and remodeling of the mandibular and maxillary bone will occur when gentle sustained pressure is applied to the teeth through the bracket and wire system. The Click-It ceramic self-ligating bracket has self-ligating properties and will include maxillary and mandibular brackets from second bicuspid to second bicuspid. The device consists of a polycrystalline alumina bracket with two polycrystalline alumina jaws, a nickel titanium spring and two nickel titanium pins.

The design of a self-ligating bracket enables the archwire to be ligated to the bracket without the use of auxiliary devices such as wires or elastics. It enables quicker archwire placement without any significant change in the mechanics when compared to the devices for which substantial equivalence is claimed.

As its predicates, Click-It ceramic self-ligating bracket enables several types of tooth movements throughout the treatment such as: tipping, translation (bodily movement), torque, extrusion, rotation, and intrusion.

{1}------------------------------------------------

The Click-It ceramic self ligating brackets are bonded to the buccal and labial surface of teeth and enable the orthodontic treatment.

#### Intended Use of the Device

The Click-It ceramic self-ligating bracket is intended to be used in an orthodontic treatment with the aim of moving teeth.

#### Technological Characteristics

Click-It can be considered substantially equivalent to the predicate orthodontic products legally marketed. The devices that substantial equivalence is claimed are; In-OvotionC by Dentsply International, Clarity Modified Ceramic Brocket by 3M Unitek Corporation and Damon 4Clear by Ormco Corporation as shown in Table 4-1. All the devices with substantial equivalence are ceramic self-ligating brackets intended to be used in an orthodontic treatment with the aim of moving teeth. All the devices with substantial equivalence when used in traditional treatment are bonded to the labial and buccal surfaces of the patient's teeth after which an archwire is ligated into the slot of each bracket. The combination of brackets, archwire and auxiliaries results in corrective forces moving the teeth into optimal positions are partially predetermined by the predefined tips, torques, and In/Out values utilized by the proven treatment prescription such as Roth, MBT or similar industry prescriptions listed in table 4.1 under "Available prescriptions". The ligating mechanism present in these brackets enables selfligation through the device design, eliminating the need of elastomeric or metallic ligatures. In special cases where self-ligation is difficult to achieve, standard ligatures may be used. Auxiliaries may be used together with the bracket/archwire/ligatures to increase the effectiveness of the orthodontic treatment.

#### Performance Testing

The Click-It orthodontic appliance has the same intended use as the predicates and similar technological characteristics. Bench and laboratory testing was conducted to demonstrate performance (safety and effectiveness) of ceramic self ligating brackets. The following tests have been conducted:

- Bond strength (ISO 11405:2003 (E)) Comparison of the shear bond strength of the . Click-It and predicate devices. The performance of Click-It brackets were determined to have comparable shear bond strength to the predicate devises. De-bonding of Click-It

{3}------------------------------------------------

brackets was found not to cause any enamel damage and performs as the predicate devises.

- . Friction test – Comparison of the wire to bracket frictional characteristics of the Click-It and predicate devices. Data analysis determined that Click-It ranks second out of the four bracket systems tested, closely following Clarity SL and outperforming both Damon 4Clear and In-Ovation C.
- . Escapement test - Comparison of wire escapement characteristics of the subject and predicate devices. The Click-It brackets performed as expected in a manner similar to the predicate devices. Click-It brackets were found to retain the wires in normal orthodontic procedures. More severe case will require additional ligatures.
- . lmpact test - Comparison of the catastrophic disassembly of the subject and predicate devices should the brackets fail from an impact. The Click-It bracket broke in such a manner not to cause the patient harm. The broken parts were of sufficient size to be easily expelled from the mouth. Any particles that cannot be seen by the naked eye could be ingested and expelled without harm to the patient. The Click-It bracket performed as expected fracturing in a manner that does not impart shards into the patient's mouth and failed in a similar fashion to the predicate devices.
- Pull test Comparison of the bracket/bond performance of the subject and predicate ● devices. The Click-It bracket de-bonded by the bond failing in shear at the bracket/adhesive interface. This is how a bracket should fail and the Click-It performed as well as or better then the predicate devices. The Click-It brackets also meet the predefined acceptance criteria set forth in the testing.
- Archwire Slot Dimensional Comparison Comparison of the archwire slot characteristics o of the subject and predicate devices. The Click-it bracket is dimensionally similar to the predicate devices and conforms to the design specification. The archwire slot is of a design that will allow the Click-It to perform properly.

Test results demonstrated that the Click-It ceramic self ligating brackets comply with the predetermined requirements and preformed similar to predicate devices.

#### Biocompatibility Testing

Click-it was found to meet the biocompatibility requirements set forth in the appropriate sections of ISO 10993. The click-It bracket meets applicable biocompatibility requirements as listed in section 14 and is safe for use.

#### Safety and Effectiveness Conclusion

Based on the comparison of devices and performance testing results, TP Orthodontics, Inc. concludes that the Click-It device is safe and effective and substantially equivalent to the predicate devices as described herein. ·
