Shoulder preparation
Also known as step preparation, this is the most modern and sophisticated tooth preparation technique. The most suitable method for the fabrication of CAD/CAM digital dental restorations.
The stability, esthetics, accuracy of fit and retention of the crowns are determined by the shoulder preparation, the technique of grinding.
Our specialist dentists and dental technicians prefer to avoid partially deposited layers of the crown abutment that are too thin. at the Denis & Focus Dental Clinic rounded preparation shapes, such as the shoulder preparation with a rounded inner edge. Like any precision work, it requires a lot of effort to grind and finish the tooth. This results in a good marginal seal quality and a clearly visible preparation margin. It secures the edge at the base of the tooth, the space required to support the Crown. In this way, shoulder preparation contributes to esthetics, but also to optimal oral hygiene, as the crown closes better and infiltrations are avoided.
The tangential preparations known from the past no longer meet the modern demands of patients in terms of esthetics. It leads to long and large crowns in the crown margin area and has disadvantages in terms of accuracy of fit and marginal contour (at the edge of the crown).
