Abstract
A method for determining a quality feature of a dental treatment comprises the detection of a patient's radiographic image data set before the creation of a drill hole for a dental implant, the detection of a patient's non-radiographic image data set after the creation of the drill hole for a dental implant by means of a drilling tool, the correlation of the radiographic image data set and the intraoral non-radiographic image data set, and the determination of the quality feature from the correlation of the radiographic image data set and the non-radiographic image data set. A device (1) that comprises a computer (10), an interface (11) for detection of a radiographic image data set, and an interface (12) for detection of a non-radiographic image data set is equipped to carry out this method. This detection of the quality feature can take place during implantation, after it is concluded, or after mounting of a dental treatment on the implant(s) is concluded.
