The spectrum of reconstructive dentistry is today more versatile than ever, as both requirements for minimal invasiveness as well as high aesthetics and stability of the reconstruction must be fulfilled.
Preparation with veneers, overlays (tabletops) and adhesive bridges, which aim at minimal tooth substance removal and are merely defectoriented, are often used today where formerly conventional crowns and bridges were used. Through the adhesion to the tooth substance, modified requirements are now placed on the preparation. In addition, a great variety of dental materials and manufacturing techniques are used at present.
Full ceramic and metal-ceramic restorations can be used equally for almost all indications. Numerous stable ceramics have been developed in recent years, whose dental processing has been facilitated by new CAD/CAM technologies.
Methods for optical impression, and therefore to digitize tooth stumps, are increasingly being used instead of classic impressions commonly applied in dental surgeries. All these computer-based technologies lead to the need for new approaches in the teeth preparation.
A modern instrument set for preparation must meet all these requirements, be universally applicable and still be clear and well-structured.
With this well-structured, rational set of instruments, various preparations for minimally invasive reconstruction, conventional crowns and bridges, for full ceramic and metal-ceramic, can
be made.
