In recent years the development of digital tools like CAD/CAM techniques and impression taking promised a revolution in clinical practice. Adj. Professor Dr. Christian Mehl, Munich/Germany, examines whether these promises can be delivered or if conventional techniques are still superior. He summarizes the advantages and disadvantages of the use of digital means in dentistry, especially impression taking.
Conventional impression techniques are still equal to digital impressions with regards to precision, but the use of digital intraoral scanners increase the comfort for the patient. He states that with the exception of large edentulous areas digital impression taking can be used for all indications.
Patient cases are used to compare the conventional method with a digital workflow. Furthermore, implant cases are shown to exemplarily show the treatment execution prosthodontically.
