The device aids in tooth extraction and site preparation for implants by severing ligaments and disengaging bone, but it does not directly restore or improve a damaged body function or treat a disease.
No
The device is described as an aid for tooth extraction and site preparation for dental implants, focusing on a mechanical function to sever periodontal ligaments. It does not perform any diagnostic function.
No
The device description clearly describes a physical handpiece with a solenoid, tips, and a foot switch, indicating it is a hardware device with electromechanical components, not software only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to expand the tooth socket and prepare the site for tooth extraction or implant placement. This is a surgical/procedural use, not a diagnostic one.
- Device Description: The device functions by mechanically severing periodontal ligaments and pushing alveolar bone. This is a physical action performed on the patient's body, not a test performed on a sample taken from the body.
- Lack of Diagnostic Elements: There is no mention of analyzing samples (blood, tissue, etc.), detecting substances, or providing information for diagnosis.
IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not fit that description.
N/A
Intended Use / Indications for Use
This device is to be used to expand the tooth socket to facilitate tooth extraction due to caries (decay), trauma, orthodontic reasons, periodontal bone loss, or malformation of the tooth, and/or to prepare the site for placement of endosseous dental implants or abutments.

Device Description
The Powertome periotome is designed as an aid to dental professionals in the extraction of a tooth, or multiple teeth, from their socket. It is designed to minimize alveolar bone loss, thus providing an initial step in the preparation prior to placing dental implants, whose success rate is highly dependent on minimal (or no) bone loss. It functions by severing the periodontal ligaments that attach the cementum of the tooth to the alveolar bone, by use of different sized and shaped tips that provide the leverage and effect desired. These ligaments are one of two methods by which teeth stay in the jaw. The second function is to push the alveolar bone away from the tooth, thus disengaging the mechanical leverage the alveolar bone uses on the imequiarity of the tooth to also help hold the tooth in place. Once the ligaments are cut, and the alveolar bone pushed away, the tooth extracts trivially.
Our method is the same as #3 (Use of a manual periotome and mallet), above, except that instead of an assistant tapping on the end of the periotome with a mallet, we use a small solenoid in the handpiece, which delivers a small but consistent force on the periotome tip, controlled in duration by the professional by use of a foot switch (for on/off control). The total delivered power for each stroke is controlled, and can be set by the professional.
This product was designed to simulate the action that is provided by the mallet, but to give greater control over the process, both from a safety (totally controlled by the professional) and effectiveness (controlled stroke allows the professional to easily determine when the tooth has been sufficiently loosened in it's socket). The materials used that come in contact with the patient are the same as used in the manual periotomes - wrought stainless steel. The tips employed are of the same general length, width, and depth as those currently used by manual periotomes.

Trade Name - PowertomeTM Periotome S100
Common name - periotome
Classification name - probe, periodontic (21CFR872.4565, Product Code ElX) We are claiming substantial equivalence to a device made by B.T.I. BIOTECHNOLOGY INSTITUTE. S.L., Osseous Technologies of America, Karl Schumacher, and others, called a periotome.
Device description: The Powertome periotome is designed as an aid to dental professionals in the extraction of a tooth, or multiple teeth, from their socket. It is designed to minimize alveolar bone loss, thus providing an initial step in the preparation prior to placing dental implants, whose success rate is highly dependent on minimal (or no) bone loss. It functions by severing the periodontal ligaments that attach the cementum of the tooth to the alveolar bone, by use of different sized and shaped tips that provide the leverage and effect desired. These ligaments are one of two methods by which teeth stay in the jaw. The second function is to push the alveolar bone away from the tooth, thus disengaging the mechanical leverage the alveolar bone uses on the imequiarity of the tooth to also help hold the tooth in place. Once the ligaments are cut, and the alveolar bone pushed away, the tooth extracts trivially.
Typical methods of extraction of a tooth are:
-
- Use of forceps. The forceps grab the tooth, and the professional then twists the tooth in place, tearing the periodontal ligaments, and also expanding the alveolar bone. Once there is sufficient clearance, and the periodontal ligaments are detached, the tooth can be removed. This results in significant bone loss, and can be painful for the patient.
-
- Use of a manual periotome: The periotome is inserted between the tooth and gum, and pushed between the tooth and bone until it meets resistance. The device can then be pushed toward the root of the tooth by moving the periotome back and forth, tangentially to the tooth surface,
-
- Use of a manual periotome and mallet: The periotome is inserted between the tooth and gum. and pushed between the tooth and bone until it meets resistance. The device can then be tapped on the end with a mallet, driving it through the periodontal ligaments the root of the tooth. Often the use of the mallet is done with an assistant, who taps the end of the periotome with the mallet equal to the number of times the professional says "tap tap" (in this example, 3 taps with the mallet).
-
- Our method is the same as #3, above, except that instead of an assistant tapping on the end of the periotome with a mallet, we use a small solenoid in the handpiece, which delivers a small but consistent force on the periotome tip, controlled in duration by the professional by use of a foot switch (for on/off control). The total delivered power for each stroke is controlled, and can be set by the professional.
This product was designed to simulate the action that is provided by the mallet, but to give greater control over the process, both from a safety (totally controlled by the professional) and effectiveness (controlled stroke allows the professional to easily determine when the tooth has been sufficiently loosened in it's socket). The materials used that come in contact with the patient are the same as used in the manual periotomes - wrought stainless steel. The tips employed are of the same general length, width, and depth as those currently used by manual periotomes.
Intended use: The intended use of this device is as an aid in the removal of teeth, due to caries(decay), trauma, orthodontic reasons, periodontal bone loss or malformation of the tooth. It is also intended to be used to remove teeth as part of the preparation for dental implants, where minimizing bone loss is critical.
All types of devices typically used in extractions, including forceps, periotomes, dental elevators, and even chisels, are Class I, exempt from 510(k). The specific indications for use have been taken from advertising done by various dental distribution or manufacturers, and, although not verbatim on our intended use, have very similar wording. Differences do not impact the safety, not the effectiveness of this device when used as labeled.
Technological characteristics: Our device does have different technological characteristics from the predicate device. The power source to cut through the periodontal ligaments and expand the bone are done either by manually forcing the tip through the ligaments, or with an external power source consisting of an assistant and a hammer (mallet), used to supply additional force to out through the periodontal ligaments and expand the socket. To determine the amount of force, and do a comparison with our device, we tested the amount of force delivered by utilization of our device, and with a hammer, and also characterized typical numbers by interviewing professionals:

| Characteristic | Predicate Device | Powertome periotom |
|---|---|---|
| Maximum amount of force/stroke | 122 lb | 90 lb |
| Minimum amount of force/stroke | 16 lb | 21 lb |
| Standard deviation force/stroke | 27 lb | 15 lb |
| Mean force/stroke | 79 lb | 52 lb |
| Frequency | 200 milliseconds/stroke | 50 milliseconds/stroke |
| Duration of impact | 420 ms | 70 ms |
| Force controlled by professional | No | Yes |
| Max/Min length of power1 stroke | 1/3 - 10" | .01" max., .01" min. |
Clinical data: We have not used clinical data to support our claim of substantial equivalence.
Anecdotal data: Two dental professionals have been using prototype versions of the product. Neither practitioner wishes to return to the manual periotome with mallet, as the Powertome periotome provides significantly increased control over the outcome.
Conclusions:
| Characteristic | Predicate Device | Powertome periotome |
|---|---|---|
| Success in cutting periodontal | ||
| ligament | Yes, with verbal control | Yes, with electronic control |
| Success in expanding tooth | ||
| socket by movement of alveolar | ||
| bone | Yes, with verbal control | Yes, with electronic control |
| Repeatability | Low | High |
| Safety: Force controlled by | ||
| professional | No | Yes |
The Powertome periotome is as safe and as effective as the predicate device in performing it's indicated use.
