How to take photos for an optimal scan of the tooth
The tooth has been extracted and cleaned. You are ready to create a 3D model of the tooth, but how exactly do you go about it?
With the scan app r3DPhoto, a perfect scan of the freshly extracted tooth can be created in just a few minutes. After extraction, the tooth is placed so that it stands upright and does not fall over. A plasticine, such as conventional children's plasticine, is suitable as a support.
Choose an approach:
There are two ways you can photograph the tooth with our app: Either move the camera around the object and photograph it from different angles and at different heights, or place the tooth on a turntable or sheet of paper and rotate it as you photograph. If you use a turntable, you should take the images against a well-lit, monochrome background to minimize extraneous data that could interfere with the object creation process.
The number of images needed by r3DPhoto to create an accurate 3D representation depends on the complexity and size of the tooth, but adjacent images must overlap significantly. Position the successive images so that they overlap by at least 70%. If there is less than 50% overlap between adjacent images, the object creation process may fail or result in an inferior replica. Be sure to position the tooth so that it fills as much of the camera frame as possible without excluding or cutting off any part. Usually 30-80 photos are taken of the tooth.
Don't worry if creating a 3D model of the tooth doesn't work the first time. There is no limit to the number of scans. You can keep trying to scan until you achieve the desired result.
