The logo features a stylized blue circle with a wave-like line running through it, and several blue dots above the circle. The word "Oventus" is written in a stylized font below the circle, with the "E" in Oventus represented by three horizontal lines. * This is assumed as the devices are FDA 510(k) cleared and are currently on the market. Only the OVENT device was tested as part of this submission. Note (1) The OVENT has a choice of lingual flange (to be decided by the clinician) although for most cases adequate retention (in advanced position) is achieved by the moulded polymer insert, the LISA relies on the lingual component for holding the mandible forward. {7}------------------------------------------------ Image /page/7/Picture/0 description: The image shows a logo for a company called "Oventus". The logo features a stylized blue circle with a wave-like shape inside, suggesting water or movement. Above the circle are several small blue dots that appear to be moving away from the circle. The company name "Oventus" is written in a simple, sans-serif font below the circle, with a trademark symbol to the right. Note (2) The OVENT has dedicated breathing port (delivering air to the rear of the mouth) to allow the user to breathe through their mouth if they want, the TAP allows users to open their mouth to a degree, whereas for the LISA, if the user opens their mouth the lingual structure no longer supports the mandible and the lower jaw moves back. Note (3) The OVENT and the TAP retain the top and bottom teeth in rigid trays whereas the LISA only retains the top teeth Note (4) The OVENT requires a new insert to be made for mandibular adjustment, the TAP device can be adjusted by the clinician or patient and the LISA requires a whole new device to be made Note (5) The OVENT uses titanium, the TAP stainless steel and the LISA has no metal parts ## Non-Clinical Tests Performed [807.92(b)(1)] - a. Biocompatibility testing was performed as outlined in the FDA-modified "Use of International Standard ISO-10993, Biological Evaluation of Medical Devices Part-1: Evaluation and Testing" for a surface device that contacts intraoral (i.e., mucosal, gingival, and palatal) surfaces for prolonged contact. Testing was conducted as described in Parts 5 and 10 of ISO-10993 the standard at a certified, independent laboratory. The OVENT passed all 4 tests as per the pass/fail criteria of the standards - cytotoxicity, skin sensitization, intraoral mucosa irritation and intracutaneous reactivity. - b. Peel/Bond strength was determined for the titanium to the acrylic and the acrylic to the dental laminate materials before and after accelerated aging in an oral simulation solution. Aging duration was calculated to be equivalent to 1 year of nightly use. The bond strength pass/fail criterion was set at 1N/mm or 10N overall strength for a 10mm interface length. The peel strength was tested as per DD253-2001: Mouth guards for use in sport and recreation - Requirements and test methods. All the OVENT materials before and after aging - had peak strengths greater than 1N/mm (>10N for a 10mm wide sample) and consequently have suitable bond strengths for the device application**. ** The key objective was to ensure that any degradation at the interfaces did not result in oral fluid ingression. All strengths were well above the set value and no fluid ingression resulted. If the inserts were removable for cleaning rather adhered to the titanium - mechanical retention would be required and the peel strength would be substantially less. {8}------------------------------------------------ Image /page/8/Picture/0 description: The image shows a logo for a company called "Oventus". The logo features a stylized blue circle with a wave-like shape inside. Above the circle are several smaller blue circles that appear to be ascending in size. The company name "Oventus" is written in a simple font below the circle. ## Clinical Tests Performed [807.92(b)(2)] Human clinical studies were not deemed necessary to evaluate the performance of the device to determine substantial equivalence as the OVENT does not: - Use designs dissimilar from the predicate device and other previously-cleared devices under a 510(k); - . Use new technologies different from legally-marketed intramandibular repositioning devices for snoring and/or obstructive sleep apnea; - Deviate from the indications for use identified in the predicate devices: the TAPIII and the LISA. In lieu of human clinical testing, the risks and mitigating controls associated with the use of mandibular repositioning devices, as identified by the FDA, have been addressed in the "Risk Assessment". In addition, adequate warnings and precautions are found in the "Instructions for Use". ## Conclusion [807.92(b)(3)] The OVENT is considered to be substantially equivalent to the predicate devices based on the following: - . Differences in the wording of intended uses between the subject and predicate devices are not critical to the intended therapeutic use of the device. - It has equivalent technological characteristics to the predicates. - The device is as safe, as effective and performs as well as than the legally marked . devices identified above.
