Traditionally, there are many variables in an indirect restorative procedure so that the quality of the final result is virtually unforeseeable. Occurring errors during the production process may add up and lead to inaccuracies of fit. As a consequence, time-consuming adjustments or even remakes may be required.
As shown from the experience of dental laboratories, the integration of digital production technologies is one decisive step towards more predictable outcomes. Another is the use of intraoral scanners in the dental office.
This is what really stayed in the minds of those listening to the chairman Dr. Daniel Poticny (Texas) and ten experts of conservative, restorative and implant dentistry. In their lectures, they focused on scientific facts and clinical experience regarding the use of intra-oral scanners and the subsequent steps in the digital workflow of restorative dentistry.
From a scientific viewpoint presented by Prof. Dr. Bernd Wöstmann (Gießen, Germany), the available intraoral scanners may be recommended for quadrant scans to produce single tooth restorations and bridges. On top of that, the 3M™ True Definition Scanner even offers a higher accuracy than impression materials and existing intraoral scanners when it comes to full arch scans. This was revealed by PD Dr. Jan-Frederik Güth (Munich, Germany) showing the results of his in-vitro study. In the clinical environment, full arch scans are already being used successfully. In this process, predictability is ensured due to the option of checking the quality of the preparation and the captured digital model immediately after impression taking.
However, with impression taking, the potential of intraoral scanners is far from being exhausted: Prof. Dr. Albert Mehl (Zürich, Switzerland) demonstrated that wear processes and periodontal changes may be visualized by superimposing different scans. Dr. Paulo Monteiro (Caparica, Portugal) suggested taking scans of every patient to set up a digital database for future repair and restoration processes as well as forensic research.
Gateway to minimally invasive dentistry
In addition, digital impression systems provide direct access to innovative materials which, in turn, allow for minimally invasive restorations. For example, a new class of hybrid materials like Lava™ Ultimate CAD/CAM Restorative has become the preferred option of many speakers when it comes to restoring functionally demanding cases. Prof. Dr. Stefan Koubi (Marseille, France) showed that he uses the elastic material for patients with severe wear to avoid sacrificing healthy tooth structure. A similar approach was adopted by Prof. Dr. Daniel Edelhoff (Munich, Germany). He presented cases of patients with parafunctional behaviour, cleidocranial dysplasia and periodontal disease who were restored with the resin nano ceramic material. Prof. Dr. Gerwin Arnetzl (Graz, Austria) prefers to use it for the production of implant abutments and crowns, since it functions as a shock absorber.
Recommendations on how to cement different kinds of CAD/CAM restorations were given by Prof. Dr. Claus-Peter Ernst (Mainz, Germany). He showed that depending on the strength of the restorative material and the indication, a conventional, self-adhesive or adhesive cementation process may be required.
Combination of digital technologies
Prof. Dr. Daniel Wismeijer (Amsterdam, the Netherlands) focused on other existing digital technologies like face scanners, CT scans, 3D printing technologies etc. which may be combined with optical impressions in the future. In this way, it will be possible to implement complete digital workflows e.g. in implantology. For a more practical use of the available technologies, smartphone applications are already being developed, as shown by Dr. Walter Devoto (Sestri Levante, Italy).
In the final discussion, speakers and participants agreed that there are many benefits resulting from digital processes. In order to leverage them, it is essential not to wait, but to go digital now!
