No
The description focuses on mechanical components and a manual activation process, with no mention of AI/ML terms or data processing.
Yes
The device is intended to treat specific medical conditions (trauma, periodontal disease, birth abnormality) by providing temporary stabilization and gradual expansion of the alveolar ridge, which aligns with the definition of a therapeutic device.
No
The device is described as a "Chin Distractor" for "alveolar ridge augmentation" and "gradual expansion of the alveolar ridge." This indicates a therapeutic or reconstructive purpose rather than a diagnostic one.
No
The device description explicitly states it consists of physical components like bone plates, a threaded activation rod, and a distraction instrument, which are manufactured from titanium. This indicates it is a hardware device, not software-only.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health. This information is used for diagnosis, monitoring, or screening.
- Device Function: The description clearly states that this device is an implantable system used for surgical intervention (distraction osteogenesis) to augment the alveolar ridge. It directly interacts with the patient's bone and tissue.
- Intended Use: The intended use is for treating a physical condition (alveolar ridge deficiency) by providing temporary stabilization and gradual expansion. It does not involve analyzing biological samples.
The device is a surgical implant, not a diagnostic tool that analyzes samples outside the body.

Intended Use / Indications for Use
This device is intended for use in patients requiring alveolar ridge augmentation of the mandible or maxilla secondary. This includes conditions secondary to trauma, periodontal disease or birth abnormality. The device is intended to provide temporary stabilization and gradual expansion of the alveolar ridge.

Device Description
The Chin Distractor is a distraction osteogenesis system consisting of two bone plates, a threaded activation rod and a distraction instrument. The plates attach to bone using bone screws and then gradually distract the osteotomized segment via activation of the threaded rod with a distraction instrument. The implanted components of the device are manufactured from titanium.

Device: Chin Distractor
The Chin Distractor is intended for use in patients requiring alveolar ridge augmentation of the mandible or maxilla. This includes conditions secondary to trauma, periodontal disease or birth abnormality. The device is intended to provide temporary stabilization and gradual expansion of the alveolar ridge. This device is a distraction osteogenesis system consisting of two bone plates, a threaded activation rod and a distraction instrument. The plates attach to bone using bone screws and then gradually distract the osteotomized segment via activation of the threaded rod with a distraction instrument. The implanted components of the device are manufactured from titanium.
The Chin Distractor is substantially equivalent to several other legally marketed devices. Examples of these are:
