Innerhalb weniger Jahre hat sich das Angebot an intraoralen optischen Abformsystemen deutlich vergrößert. Die Möglichkeiten und das Potenzial der digitalen Abformung mit intraoralen optischen Abformsystemen sind heutzutage unumstritten. Zahlreiche Innovationen sowie Indikationserweiterungen in den Bereichen Kieferorthopädie und Implantologie lassen die intraoralen Scansysteme als äußerst vielversprechend und zukunftsträchtig erscheinen. Die digitale Abformung mittels Intraoralscannern ist der konventionellen Abformtechnik in manchen Punkten bereits deutlich überlegen. Die vielseitige Integration der digitalen Abformung in Diagnostik- und Therapiekonzepte im Rahmen eines "Healthcare-Pakets" für den Patienten erscheint besonders erwähnenswert. So bleibt mit Spannung zu sehen, wann die digitale Abformung - ähnlich wie bereits etablierte digitale Applikationen im alltäglichen Leben - ein selbstverständlicher Bestandteil der zahnärztlichen und zahntechnischen Tätigkeit sein wird. Innerhalb des vorliegenden Artikels wird eine Übersicht über die Vorteile und Einschränkungen der digitalen Abformung mit Intraoralscannern gegeben. Zudem liefert er eine Zusammenfassung sämtlicher heutzutage relevanter Intraoralscanner.

A monolithic restoration (also known as a full contour restoration) is one that is manufactured from a single material for the fully anatomic replacement of lost tooth structure. Additional staining (followed by glaze firing if ceramic materials are used) may be performed to enhance the appearance of the restoration. For decades, monolithic restoration has been the standard for inlay and partial crown restorations manufactured by both pressing and computer-aided design and manufacturing (CAD/CAM) techniques. A limited selection of monolithic materials is now available for dental crown and bridge restorations. The IDS (2015) provided an opportunity to learn about and evaluate current trends in this field. In addition to new developments, established materials are also mentioned in this article to complete the picture. In line with the strategic focus of the IJCD, the focus here is naturally on CAD/CAM materials.

In 55 patients, 25 endocrowns (test) and 40 shoulder crowns (control) were produced chairside in a private practice using the Cerec 3 (CAD/CAM) method and Vita Mark II feldspathic ceramic. The crowns were examined at baseline and after up to 12 years using modified USPHS criteria. The survival estimate was assessed by Kaplan-Meier analysis. The 12 years survival estimate of the shoulder crowns was 95% on molars and 94.7% on premolars. Endocrowns showed 90.5% survival on molars and 75% on premolars. Statistically, the differences between the survival estimates were not significant (P > 0.05). The longevity of Vita Mark II Cerec 3 shoulder crowns on molars and premolars, as well as of endocrowns on molars, proved to be - for private practice - a very acceptable result, while the premolar endocrowns tended to show a higher risk for failure.

It is now possible to produce full-digital drilling templates with Cerec Guide 2 (Sirona) in the dental practice relatively quickly, efficiently, and economically. Here, a patient case example is used to present an exemplary description of the procedure and method to do this. The solution described herein shows the advantageous efficiency, compared with other systems presently on the market, of a procedure that does not require the external production of the drilling template in the laboratory or a manufacturing center.

Dental materials, especially in restorative dentistry, must not only be cost-effective, they must also meet many other requirements: biocompatibility, durability, excellent shade and light effects, abrasion resistance, hardness, mechanical strength under pressure, chemical resistance, surface density, ease of manufacture, and easy intraoral maintenance.
