The Synthes Alveolar Distractor is intended for vertical bone lengthening of the alveolar ridge in the mandible and the maxilla where gradual bone distraction is required, including deficiency in bone height as a result of:
- . Trauma
- Resorption after dental extraction .
- Periodontal disease .
- Tumor resection ◆
- Congenital deformity .
The Synthes Alveolar Ridge Distractor is an extraosseous distraction device consisting of a distractor body, a transport plate, a base plate, and a vector control mechanism. It is intended to be placed submucosally, with the base plate fastened to the stationary segment of the mandible or maxilla and the transport plate fastened to the mobile bone segment. The plates are fixed to the bone using 1.5 mm cortex screws.
The provided document is a 510(k) summary for the Synthes Alveolar Ridge Distractor, which is a premarket notification to the FDA for a medical device. This type of document focuses on demonstrating substantial equivalence to a previously marketed device rather than providing the results of a primary clinical study with acceptance criteria.
Therefore, the document does not contain the information requested regarding acceptance criteria and a study proving the device meets those criteria. Specifically:
- No acceptance criteria or device performance table is present. The document states that "Documentation was provided which demonstrated the Synthes Alveolar Ridge Distractor to be substantially equivalent to other legally marketed devices." This implies a comparison to predicate devices, not specific performance metrics against pre-defined acceptance criteria.
- No details about sample size for a test set, data provenance, number of experts, adjudication methods, MRMC studies, standalone performance, or training set are provided. These are typically elements of a clinical trial or performance study, which is not the primary purpose of a 510(k) summary focused on substantial equivalence.
- The type of ground truth used is not specified.
- The sample size for the training set and how its ground truth was established are not mentioned.
The 510(k) process primarily relies on demonstrating that a new device is as safe and effective as a legally marketed predicate device, often through bench testing, material characterization, and comparisons of design and intended use, rather than extensive clinical efficacy trials. The document highlights the intended use and predicates but does not detail a study proving specific performance metrics against acceptance criteria.

Trade/Device Name: Synthes (USA) Alveolar Ridge Distractor Regulation Number: 872.4760 Regulation Name: Bone Plate Regulatory Class: II Product Code: MQN Dated: March 17, 2005 Received: March 18, 2005
Dear Ms. Anderson :
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.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Eederal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (240) 276-0115.
