Abstract
The invention relates to a method for checking tooth positions, wherein an initial three-dimensional volume exposure () of teeth () to be checked is implemented, wherein the position and orientation of the teeth () to be checked are determined based on the initial volume exposure (); wherein the teeth to be checked are natural teeth () comprised of tooth stumps () and tooth roots () and/or are artificial teeth comprised of artificial tooth stumps and implants; wherein the positional relationship and orientation of the tooth stumps () relative to the tooth roots () and/or to the implants are determined in particular. For checking, a first optical surface monitoring exposure () of the teeth () is implemented, wherein using the positional relationship thus determined the position and orientation of the tooth roots () and/or of the implants relative to one another and/or relative to a jawbone () are determined based on the position of the surfaces () of the tooth stumps () from the optical surface monitoring exposure ().
