Intended Use

The CDB Self Ligating 8F bracket is indicated for orthodontic movement of uncompromised natural teeth, excluding mandibular bicuspid.

Device Story

CDB Self Ligating Bracket 8F is an orthodontic ceramic bracket bonded to teeth to apply pressure via a flexible orthodontic wire. The device features a self-ligating clip mechanism that facilitates wire placement and removal. It is used by orthodontists in a clinical setting to alter tooth position. The bracket is composed of aluminum oxide with a nickel-titanium clip, coated in gold or rhodium. The clip slides to hold the wire in passive, interactive, or active states. The device benefits patients by providing an aesthetic, translucent orthodontic system for tooth alignment.

Clinical Evidence

Bench testing only. Comparative shear bond strength testing was conducted against the predicate device, demonstrating that the bond strength of the CDB Self Ligating Bracket 8F is as strong as the predicate.

Technological Characteristics

Bracket body: Aluminum oxide. Clip: Nickel-titanium with gold or rhodium coating. Principle: Mechanical retention via bonded ceramic bracket and sliding self-ligating clip. Form factor: Translucent/clear bracket system. Manufacturing: Injection molding, sintering, stamping, and plating. Permanent surface-contacting device (mucosal membrane).

Indications for Use

Indicated for orthodontic movement of uncompromised natural teeth, excluding mandibular bicuspids.

Regulatory Classification

Dear Yannire Thompson:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug. and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.

The logo consists of the letters "cdb" in a stylized font, with the top half of the letters in a lighter blue and the bottom half in a darker blue. The words "CERAMIC DENTAL BRACKETS" are written in a smaller font below the letters.

| FDA requested to provide the name of another predicate device that has the same chemical composition as CDB Self Ligating Bracket 8F clip material. Please see below for two reference devices: |
|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Click-it (K111234) by TP Orthodontics. Click-it is a self ligating ceramic bracket with a Nickel titanium clip. |
| Clarity SL (K062345) by 3M Unitek. Clarity SL is a self ligating ceramic bracket with a Nickel titanium clip. |
| Conclusion: |
| By definition, a device is substantially equivalent when the device has the same intended use and the same technological characteristics as the predicate devices. |
| There are no major differences between the CDB Self Ligating Bracket 8F and the predicate device cited; therefore the CDB Self Ligating Bracket 8F, as designed, is determined to be substantially equivalent to the referenced primary predicate device and reference devices currently on the market. |
