The sequential aligners introduce incremental movements that move teeth by way of gentle continuous force. The aligners are to be worn 20-22 hours a day for an average of 2 weeks per aligner or as directed by the clinician and are to be removed only for eating and for cleaning. A digital or traditional mold impression of the patient's dentition is provided by a dental health professional (e.g. orthodontist or dentist). From the digital data of the {4}------------------------------------------------ patient's dentition. 3Shape A/S Ortho System is used to develop treatment plan. Using the software, dental technicians design a series of intermediate models corresponding to each stage of treatment, gradually realigning the patient's teeth according to the dental health profession's prescription. The prescribing doctor reviews and approves the model scheme and treatment plan before the molds/models are produced. Once approved, the 3Shape A/S Ortho System, is used to generate standard format 3D files which are used to physically produce each model/mold in the treatment plan for aligner fabrication. Johns dental laboratories produces the aligner trays by thermal forming a plastic sheet over each model in the treatment plan. The trays are provided to the dental health care professional who provides them to the patients in sequential stages, confirming fit and design. The dental health professional monitors treatment from the moment of the first aligner is delivered to when the final aligner is finished and treatment is complete. The aligners are held in place by pressure and can be removed by the patient at any time. # INDICATIONS FOR USE The Redline Aligner is indicated for the treatment of tooth malocclusion in patients with permanent dentition (i.e. all second molars). The Redline Aligner positions teeth by way of continuous gentle force. # COMPARISON OF TECHNOLOGICAL WITH THE PREDICATE DEVICE The subject device is substantial equivalent in intended use and technological characteristics to the predicate devices shown above.

They are both intended for correcting dental malocclusion patients with permanent dentition. It has similar technological characteristic and fabricated by a similar manufacturing process to the predicate device. The application of the device is in the same clinical manner as the predicate device. Therefore, the Redline Aligner is considered to be substantially equivalent to the predicate device based on a comparison of intended use and technological characteristics. # Non-Clinical PERFORMANCE DATA Non-clinical testing have been conducted to verify that the Redline Aligner meets all design specification which supports the conclusion that it's substantially equivalent (SE) to the predicate device. Software used for treatment planning and creation of models/mold for Redline Aligner is manufactured by 3Shape A/S Ortho System. It is a 510(k) clearance (K180941) software under product code PNN for intended use. An internal manufacturing validation was performed to demonstrate the dimensional accuracy of the manufacturing for Redline Aligner. The critical aspects of the manufacturing process were assessed for accuracy. The final aligner fitness was evaluated according to the in-house fitness acceptance criteria. Translational measurement were within 0.150mm (150microns) of the target input value, the predefined tolerance of the manufacturing process. There were no statistical difference in the values measured from any of the groups. The testing results are within the acceptance criteria to demonstrate dimensional accuracy. Additionally, the final aligner fitness evaluation demonstrate all the aligners including in the study passed and were deemed an excellent fit . {7}------------------------------------------------ The biocompatibility evaluation and the determination that Redline Aligner and the predicate devices are composed of the same material, fabricated by the similar manufacturing processes, and are used in the same clinical application, which concludes that Redline Aligners are biocompatible for their intended use. Biocompatibility testing for the aligner material, the only patient contacting material, was conducted by the material manufacture in accordance with International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process". Additional cytotoxicity testing according to ISO 10993-5:2009 was performed on the final manufactured Redline Aligners . # CLINICAL PERFORMANCE DATA The clinical performance of sequential aligners (product code NXC) has been well established since the first device of this category was cleared by the FDA in 1998. The Redline aligners have equivalent indication and method of use to its primary and reference devices, therefore there was no clinical testing to support this device. # CONCLUSION The subject device has very similar technological characteristics (i.e. design, function, principle of operation, materials, biocompatibility and sterilization) to the predicate device . The intended use and indications for use of the subject device are the same as the predicate device. In conclusion, the device is substantially equivalent based on a comparison of intended use, and technological characteristics, the device is safe and effective for its intended use.
