Intended Use

The Cybird LED Curing Light is intended to polymerize resinous dental materials, restorative composite materials and orthodontic brackets, bonding and sealing materials that are photo-polymerized in the 400-480 nm waveband of visible light.

Device Description

Cybird is a LED curing light intended for rapid polymerization of light-cured materials by dental professionals. This product effectively reduces polymerization time on various lightcured materials and provides excellent treatment results every time. Cybird's body is made from industrial-grade aluminum which ensures its durability and excellent heat dissipation. The Cybird features multiple curing modes for maximum functionality.

The Cybird curing light produces visible blue light in the 405 nm (Gold) & 465 nm (Gold / XD) peak waveband of spectrum with a power density of 1,500mW/cm² (High Power Mode), 2,500 mW/cm2 (Ortho Mode, Gold), 2,700mW/cm2 (Ortho Mode, XD). These power densities are sufficient for the product intended uses.

405 nm (Gold) & 465 nm (Gold / XD) peak waveband of visible light cured (VLC) orthodontic brackets and orthodontic bonding and sealing materials.

Exposure times can be set for 1.5, 2, 2,5, 3 seconds for XD in Ortho Mode; 2, 3, 4 seconds for Gold in Ortho Mode; and 5,10,15, or 20 seconds in High Power Mode.

AI/ML Overview

The provided text describes the 510(k) premarket notification for the "Cybird LED Curing Light" and its substantial equivalence to a predicate device. However, it does not explicitly detail acceptance criteria and a study proving the device meets those criteria in the way a clinical trial or algorithm performance study would.

Instead, the document focuses on demonstrating substantial equivalence to a legally marketed predicate device through non-clinical performance testing and compliance with various standards. The "acceptance criteria" here are implied to be the standards and measurements taken to show the device performs similarly or equivalently to the predicate and adheres to regulatory requirements.

Here's an attempt to structure the information based on your request, acknowledging the limitations of the provided text:

Acceptance Criteria and Device Performance

The "acceptance criteria" for this device are primarily demonstrated through non-clinical performance tests and compliance with established standards, aiming to show substantial equivalence to a predicate device.

2. Sample Size and Data Provenance

  • Test Set Sample Size: The document does not specify a "test set" in the context of discrete data points for a predictive model. The testing involved various materials (e.g., Handae Chemical, Hanfil; Spident Escom 100; Dentkist Charmfil Plus; Mediclus Anycom) for depth of cure and hardness. The number of samples for each material or measurement is not provided.
  • Data Provenance: The tests are non-clinical (laboratory-based performance tests) and were conducted by DXM Co., Ltd. (Republic of Korea). The data is prospective in the sense that it was generated specifically for this 510(k) submission.

3. Number of Experts and Qualifications for Ground Truth

  • This information is not applicable as the document describes non-clinical performance testing of a physical device, not an AI/ML algorithm requiring expert-established ground truth for image interpretation or diagnosis. The "ground truth" for these tests would be the physical measurements and observations made by trained technicians and engineers in a laboratory setting.

4. Adjudication Method for the Test Set

  • This information is not applicable for the reasons stated above. Adjudication methods like 2+1 or 3+1 are typically used for establishing ground truth in clinical data reviewed by multiple experts, not for physical device performance measurements.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

  • No, a multi-reader multi-case (MRMC) comparative effectiveness study was not performed. This type of study is relevant for evaluating the impact of AI on human reader performance for tasks like diagnostic interpretations. The "Cybird LED Curing Light" is a physical dental device, not a diagnostic AI tool.

6. Standalone (Algorithm Only) Performance Study

  • No, a standalone (algorithm only) performance study was not done. This is also not applicable as the device is not an algorithm but a medical device.

7. Type of Ground Truth Used

  • The "ground truth" for the tests described is based on physical measurements and adherence to recognized standards. For example, Depth of Cure was measured per ADA Specification No. 48, biocompatibility per ISO 10993 standards, and electrical safety per IEC 60601 standards. These are objective, empirically verifiable metrics, not expert consensus or pathology in a clinical sense.

8. Sample Size for the Training Set

  • This information is not applicable. There is no "training set" as this is not an AI/ML device.

9. How Ground Truth for the Training Set Was Established

  • This information is not applicable for the reasons stated above.

The green shape is abstract and appears to be a stylized leaf or wave. The letters "dxm" are in lowercase and have a slightly rounded font.

Discussion of the substantial equivalence decision;

The Cybird LED Curing Light has similar characteristics and intended uses as the 510(k) cleared light curing units, the D1 LED Curing Light or SPEC3 or LED 3000 (K121093), manufactured with identical materials and using the same energy source for the photopolymerization of dental materials, restorative composite materials and polymerization of bonding and sealing materials.

These devices are well established and determined to be safe and effective.

The differences between the subject and the predicate device are the LED light source, light guard diameter, the power mode, and the exposure time.

Luminous/Radiant Flux for Cybird LED Curing Light is lower compared to the predicate device. However, light is distributed evenly on the exposure surface whereas the predicate device's light intensity is higher on the center of the surface.

These differences thus raise no new questions of safety and effectiveness and do not represent significant issues to clinical evaluation to fulfil the indication for use. In conclusion, the Cybird LED Curing Light is substantially equivalent to the identified predicate device in regard to intended use, materials of construction, performance attributes and technological characteristics.

Furthermore, the intended use of the modified device has not changed as a result of the modifications.

VII. SUMMARY OF NON-CLINICAL TESTS

The Cybird LED Curing Light has been designed and tested according to the FDA guidance for Dental Curing Lights-Premarket Notification. Verification activities included curing hardness, depth of cure per ADA Specification No. 48, maximum light intensity measurements at 2 mm for all power modes, and spectral irradiation plots of all power modes.

The Cybird LED Curing Light complies with voluntary standards for biocompatibility (in vitro cytotoxicity, irritation and sensitization testing), electrical safety and EMC testing. The following data were provided to support the substantial equivalence determination:

Biocompatibility:

All materials to be connected to the patient's skin are in conformity with AAMI / ANSI / ISO 10993-5:2009(R) 2014, Biological Evaluation of Medical Devices-- Part 5: Tests for In Vitro Cytotoxicity (L929 Assay) and AAMI / ANSI / ISO 10993-10:2010, Biological Evaluation of Medical Devices - Part 10: Tests for Irritation and Skin Sensitization. The difference of material used between subject and predicate device does not affect safety and effectiveness.

VIII. SUMMARY OF CLINICAL TESTS

Clinical testing was not required to demonstrate the substantial equivalence of the Cybird LED Curing Light to its predicate device.

IX. CONCLUSIONS

Based on the information above, the sponsor believes that Cybird LED Curing Light is substantially equivalent to the predicate device. The differences between the Cybird LED Curing Light and its predicate do not raise different questions of safety and effectiveness.
