Intended Use

Avex® CX2 ceramic brackets are intended for use in orthodontic treatment.

Device Story

Avex CX2 ceramic brackets are orthodontic appliances bonded to teeth to facilitate tooth repositioning via arch wires placed in bracket slots. Manufactured from polycrystalline alumina, these brackets feature tie wings and hooks to secure ligatures. Used in dental/orthodontic clinics, they are applied by dental professionals. The device is designed to match natural tooth color, offering an esthetic alternative to traditional metal brackets. By providing a stable attachment point for orthodontic wires, the brackets enable the application of corrective forces to teeth, benefiting patients requiring orthodontic alignment.

Clinical Evidence

No clinical performance testing was performed. Substantial equivalence is based on bench testing (bond strength, de-bond evaluations, adhesive shear strength) and literature reviews.

Technological Characteristics

Material: Polycrystalline alumina (ceramic). Design: Molded body with tie wings, hooks, and base for tooth adhesion. Slot sizes: .018 and .022. Standards: ISO 27020:2010 (orthodontic brackets), ISO 10993-1 (biocompatibility).

Indications for Use

Indicated for orthodontic treatment in patients of all ages when prescribed by a dentist or orthodontist.

Regulatory Classification

Identification

An orthodontic plastic bracket is a plastic device intended to be bonded to a tooth to apply pressure to a tooth from a flexible orthodontic wire to alter its position.

#### III. Predicate Device:

Avex CX2, ceramic brackets are a modification of Avex CX2, cleared under 510(k) K113334, also manufactured by Opal Orthodontics by Ultradent Products. Avex CX2 and Avex CXi2 are made from polycrystalline alumina (ceramic). They come in two prescriptions; McLaughlin and Opal R, with two slot sizes; .018 and .022. These brackets have the same measurement designators found in all orthodontic brackets such as angle of torque; angulation; in/out; slot height, depth, length; and dimensions of the auxiliary slot. Avex CX₂ is a bracket consisting of only the ceramic material while the Avex CXi2 has a stainless steel metal slot liner to help reduce friction between the material of the bracket in the slot and the arch wire. They are translucent and have the same basic forms as other ceramic brackets like tie wings and hooks so as to facilitate their intended use.

## Indications for use of predicate device:

Avex CX2 and Avex CXi2 ceramic brackets are intended for use in orthodontic treatment.

### IV. Device Description of subject device:

Avex® CX2 ceramic brackets are intended to be bonded to teeth upon which an orthodontic wire is placed in a slot to re-position the teeth to desired positions. Avex CX2 ceramic brackets are manufactured from polycrystalline alumina (ceramic) material and have a base which has been designed to provide adhesion to the tooth, yet allow for removal when necessary. The raw material has been documented to be biocompatible for its intended contact and duration of contact. There are several other products in the market that have the same indications as these products and the proposed modification does not affect composition, intended use, or indications for use. Opal Orthodontics has followed design control processes outlined in 21 CFR 820.30 and internal procedures to complete our design control procedure and documentation for the Avex CX2.

Avex CX2 ceramic brackets are esthetically preferred as ceramic colored arch wires are available and the vision of "metal mouth" is no longer the case for the bracket wearer. These ceramic brackets and certain arch wires are intended to match natural tooth coloring in order to reduce visibility.

Avex CX2 ceramic brackets are indicated for use in patients of all ages when prescribed by a dentist or orthodontist.

### V. Indications for use of subject device:

Avex CX2 ceramic brackets are intended for use in orthodontic treatment.

### VI. Comparison of technological characteristics Avex CX2 and Avex CXi₂, (K113334), and Avex CX2 have similar technological characteristics:

The Avex® CX2 is composed of polycrystalline alumina, which has been widely used by manufacturers in the dental industry for more than 2 decades. The efficacy or

{6}------------------------------------------------

suitability to the intended purpose of Avex CX2 has been demonstrated by a combination of inhouse testing and side-by-side comparisons to predicate devices currently on the market. Results of our testing document that Avex CX2 is substantially equivalent in performance t o predicate devices currently on the market.

Avex CX2 has been tested for bond strength, de-bond evaluations, and adhesive shear strength evaluation and met all other design inputs. The Avex CXi₂ has been tested for bond strength, de-bond evaluations, and adhesive shear strength evaluation and met all other design inputs. The comparative results of the testing demonstrated that the modified Avex CX2 is substantially equivalent to the predicate, Avex CX2 and Avex CXi2.

No clinical performance testing was performed on Avex CX2, ceramic brackets.

In conclusion, Avex CX2, ceramic brackets, have been designed and manufactured with the intended use and claims for the product in mind. Published literature, bench test data, and risk/benefit reviews have been collected and evaluated to determine substantial equivalence in safety and effectiveness of similar devices and the Avex CX2 bracket for the same indications. Therefore, the modified version Avex CX2, is substantially equivalent to Avex CX2 cleared under K113334.
