At O’Brien Dental Lab, we receive monthly requests for help in identifying unknown dental implants. In this article, I cover the best ways for you to determine what those mystery implants are.


First, start with a CLEAR radiograph

Typically, the best place to start is with a radiograph. However, to be useful, it needs to be optimally oriented to capture the characteristics of the implant precisely. So, when taking an x-ray, it’s essential to keep the following two things in mind:

  • First, ensure that the sensor or film is parallel to the implant. Establishing this alignment will provide the clearest view of the implant’s unique characteristics.
  • Second, the x-ray should capture the entire implant. The most apical end of the implant is just as important as the interface during the identification process.

If the implant and film, or sensor, are not aligned, the radiograph will not show the relevant features.


It may take multiple tries to get the ideal position, but this is essential for correct identification.

Next, find a match using a dental implant database

Once you have a radiograph that shows clearly defined features, you can use an implant database to match those features to known implants. The two primary databases are:

Both websites work similarly. On either site, you’ll choose characteristics from drop-down menus which will narrow the list of implants until you can visually match your implant with one in the database that looks the same.

The characteristics that you can choose from include thread type, implant taper, holes, grooves, and several others.

After you have narrowed down your results as much as possible, browse through the remaining implants and compare them to your radiograph to find a match.

Still unable to find a definitive match? Time to look at the parts.

Even though these online databases do their best to help you identify your suspect, since so many implants share the same characteristics, you still may not be able to make a positive ID. If this is the case, your final option is to capture detailed images of the implant PARTS with a traditional camera and send them to a dental lab such as O’Brien, or a consultation service like for manual inspection and identification. The two most important parts to capture are the screw the interface of the abutment.

It’s important that your pictures are clear and close up. An SLR camera with a macro lens is ideal, but most modern cell phone cameras are adequate as long as the phone is held steady and the image is taken with high zoom.
