(iii) the reduction of possible errors in the workflow and those caused by material defects,.(ii) the reduction of costs (e.g., obsolete imprint material and spoon, reduced delivery costs and archiving work),.

(i) the reduction of time (e.g., preparation and processing of the imprint, disinfection, and delivery of the imprint),.Advantages of the CAD/CAM technology have been summarized in Ref. 4 In addition to the increased production speed, the discussed CAD/CAM machining techniques are not affected by shrinkage (CNC machined parts) or the amount of shrinking can be compensated when generating the 3-D CAD model (3-D printed part). As a result a three-dimensional (3-D) model is generated, which can then be used to manufacture the implant using subtractive methods such as computer numerical control (CNC) machining, enabled by devices, such as the Densply Cercon Brain Expert, 2 Datron 5 axis milling machine, 3 or additive methods, such as 3-D printing, which can likewise be combined with antibacterial material. In contrast to the imprint, optically based techniques are nontactile and hence they allow measuring the same area multiple times to reduce the measurement uncertainty. Optical measurement techniques can drastically reduce the time and risk of measurement errors. 1 The first step toward digital dentistry is already well established by scanning the plaster models that originate from the conventional impression, and manufacturing the restorations with an automated computer-aided manufacturing process (CAD/CAM). It is easy to understand that, between all these steps, many sources for possible errors may occur. The conventional process of impression-taking requires many steps to finally get to the restoration, which is cemented in the patient’s mouth. In that manner, the production process of a tooth implant is based on a two-step process, which is both very time-consuming and likely to be affected by artifacts when removing the imprint (e.g., incomplete removal of the imprint, mechanical deformation), material inhomogeneities, shrinkage, and errors caused in the casting process.

The impression process can take some minutes, in which the patient, as well as the impression material, should remain in the same position to ensure a good reproduction. The negative imprint is then used to produce a positive copy of the tooth. In the conventional intraoral restoration process, a negative imprint of the tooth, which is also known as a dental impression, is taken by using self-curing elastomers.
