The device description clearly states it is an adhesive comprising a viscous polymeric resin paste and a watery component (Activator), delivered via syringe and squeeze bottle, respectively. It also includes etchant, brushes, and mixing pads. These are all physical components, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is "for bonding brackets to teeth for orthodontic treatment." This is a direct application to the human body for a therapeutic purpose (orthodontic treatment), not for examining specimens derived from the human body to provide information about a physiological state, health, or disease.
- Device Description: The description details a bonding system applied to teeth, which are part of the human body.
- Performance Studies: The performance studies focus on the physical properties of the adhesive (set-time and shear bond strength) when applied to a simulated tooth surface (acrylic rod) and brackets. These are tests of the device's functional performance in its intended application, not diagnostic tests on biological samples.
IVD devices are used to perform tests on samples taken from the human body (like blood, urine, tissue) to diagnose, monitor, or screen for diseases or conditions. This device is used on the human body itself for a treatment purpose.

Device Description
Reli-On is a one step orthodontic adhesive. It comprises of two major components, i.e., a viscous polymeric resin paste and a watery component called. Activator. The paste is delivered from a syringe, while the activator is dispensed from a squeeze bottle. Besides the paste & the activator, the product kit contains a preloaded syringe of etchant (35% phosphoric acid solution), brushes to apply the activator on the tooth and a stack of mixing pads for easy transfer of the activator.
The tooth to be bonded is etched with the etchant (conditioner) for 10-20 seconds, followed by a water rinse. The activator is applied to the surface of the etched tooth and also to the base of the bracket. The paste is then applied to the base and the bracket is placed on the tooth in the desirable clinical position. In about a minute the bracket is securely fastened to the tooth. Optimum strength is achieved in 24 hours. The product comes with a detailed instruction for use pamphlet.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Comparison studies were performed for set-time and shear bond strength.
Set-Time: Experimental procedure involved abrading an acrylic rod surface, applying Reli-On activator on the base of a Freedom MIM Roth bracket and the sanded acrylic rod, applying a thin layer of adhesive paste on the bracket base, immediately placing the bracket on the rod and starting a stop watch, then moving the bracket slowly back and forth until the adhesive sets up and it becomes difficult to manipulate the bracket. The elapsed time was noted. This was repeated with 5 different samples and the average value reported. The entire procedure was repeated for the Right-On (predicate) device. The average set-time for Reli-On was 29 seconds, compared to 28 seconds for Right-On.
Shear Bond Strength: Brackets were bonded to surface abraded acrylic rods (1" diameter and 2" long). The rod was clamped to a table overhang. Using a wire harness, the bracket was loaded with static weights up to 24 pounds, which translates to a stress of 8 MPa based on the bracket base surface area. Additional weight was added until failure to determine ultimate shear stress. This experiment was repeated with 5 different brackets for both Reli-On and Right-On. All brackets were required to pass the 24lb static load. Both the predicate device (Right-On) and the device being 510k'ed (Reli-On) passed the >8 MPa shear bond strength criterion. The ultimate shear bond strength for Right-On was 9.3 MPa and for Reli-On was 9.4 MPa.
Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)
Set-Time (average of 5 trials) for Reli-On: 29 seconds.

Performance criteria
Currently, no establilshed performance criteria are published by eminent standards bodies(i.e. ASTM, ANSI, etc.). Therefore, the following two criteria, based on the actual product use, are selected for the equivalency comparison.
The most important criteria for the optimum performance of this product are:
- (1) Set time
- (2) Shear bond strength
Set Time:
This is the time available to the clinician while manipulating the bracket to optimize the bracket location on the tooth. If the set time is too short, the clinician will not be able to place the bracket in the proper position before the adhesive sets up. Conversely, if the set time is too long, the bracket can "drift" from the desirable position, requiring constant attention until the final set has taken place. Typically the set time for one-step adhesives is in the range of 20-25 seconds. The experimental procedure for determining the set-time is outlined here.
Experimental procedure for determining set-up time for One-step (or No-Mix) adhesives.
Methods & Materials
Materials used for performing set-up time Testing
- (a) Freedom MIM Roth brackets (upper centrals) or equivalent
- (b) Acrylic rod (1" radius)
- (c) sand paper (100 grit)
- (d) explorer or an equivalent pointed probe
- (e) Reli-on test adhesive and Right-On predicate adhesive.
- (f) stop-watch or equivalent
Experimental method
Using the sand paper, abrade the acrylic rod surface. Apply Reli-On activator on the base of the bracket and on the sanded surface of the acrylic rod. Apply a thin layer of the adhesive paste on the bracket base. Immediately place the bracket on the acrylic rod (pretreated with activator) and start the stop watch. Using an explorer move the bracket slowly back and forth until the adhesive sets up and its gets difficult to manipulate the bracket. Note the time elapsed. This is the set-time in seconds. Repeat with 5 different samples and report the average value. Repeat entire procedure for Right-On (predicate) device.
Shear bond strength:
The primary mode of stress transfer to the bracket in the oral environment is through shear. The brackets are dislodged by occlusal forces as experienced during biting hard objects such as hard candy, nuts etc in the oral environment.

The adhesive should be capable of withstanding such forces. This mastication-induced force is reported to be around 6 to 8 MPa (ref 1). The experimental procedure for determining if the adhesive can support this shear load is outlined here.
Experimental procedure for determining shear bond strength
Bond brackets to surface abraded acrylic rod, 1" diameter and 2" long. (as discussed above). Clamp the Rod to a table overhang with a C-clamp. Using a wire harmess load the bracket with static weights up to 24 pounds. This load translates to a stress of 8 MPa, based on the bracket base surface area (mesio-distal width (0.138") X occluso-gingival height (0.148") "Add additional weight until failure". The experiment can be extended by further loading to determine the ultimate shear stress by loading to failure. The ultimate failure stress is also reported for the two test candidates in the results. The experimental set-up is shown in figure (1). Repeat the experiment with 5 different brackets for both the candidate adhesives. All brackets should pass the 24lb static load.

Conceptual design of the adhesive system
The adhesive system is made up of two primary components, a thick paste and a liquid activator. The activator, which contains the amine component, is applied to the surfaces of the etched tooth surface as well as to the bracket. The paste, which contains the peroxide catalyst, is then applied onto the bracket base and the bracket is positioned onto the tooth surface. The reaction proceeds from the outer surfaces towards the center.
The paste component is packaged in plastic syringes for easy delivery. The activator is packaged in a squeeze bottle. The etchant comes in a prefilled syringe. The labeling and the various components of the predicate device (Right-On) and the device being 510k'ed (Reli-On) are shown elsewhere.
