Abstract: The invention relates to a method for producing ceramic dental prosthesis parts by way of a CAD/CAM machining station, comprising the following steps that is capable of providing a disk-shaped ceramic blank, wherein the blank has the final strength; attaching the blank in a mounting device of the CAD/CAM machining station; controlling the CAD/CAM machining station for establishing an initial contact between the blank and the grinding tool in such a way that, due to the rotation of the grinding tool about the longitudinal axis thereof, the entire contact surface between the grinding tool and the blank has relative movement; and machining the blank by way of the rotating grinding tool, proceeding from the initial contact, to produce the ceramic dental prosthesis parts.

Abstract: The present teachings relate to a method for transforming a digital 3D dental model to a 2D dental image, the method including: providing, at least two selected images from the 3D dental model; converting, each of the selected images, to a respective color component of a color model; obtaining, by combining the respective color components, the 2D image in a computer-readable format of the color model. The present teachings also relate to a method of classification of the 2D image, a dental procedure assisting system, uses and computer software products.

Abstract: The invention relates to a disk-shaped blank made of a final-strength dental ceramic, comprising a casing surrounding a perimeter of the final-strength dental ceramic, the casing made of a material that is softer than the final-strength ceramic, and in particular made of wood or plastic material.

Abstract: The invention relates to a method for producing ceramic dental prosthesis parts by way of a CAD/CAM machining station, comprising the following steps:—providing a disk-shaped ceramic blank, wherein the blank has the final strength;—attaching the blank in a mounting device of the CAD/CAM machining station;—controlling the CAD/CAM machining station for establishing an initial contact between the blank and the grinding tool in such a way that, due to the rotation of the grinding tool about the longitudinal axis (13) thereof, the entire contact surface (21) between the grinding tool and the blank has relative movement; and—machining the blank by way of the rotating grinding tool, proceeding from the initial contact, to produce the ceramic dental prosthesis parts.

Abstract: A gas bag restraint system for vehicle occupants has a multi-stage gas generator and a gas bag which includes an outer wall having wall portions and having at least one fold which is formed by a first holding element. The gas bag is able to gradually take up various discrete inflation volumes in accordance with activated stages of the gas generator and dependent on an internal pressure of the gas bag. The outer wall has the at least one fold in a first, partially inflated state of the gas bag, after ignition of a first stage of the gas generator. In the first state, the outer wall has a portion defining an inflated region of the gas bag and a portion defined by the at least one fold. The fold in the first state is turned over toward the inflated region of the gas bag and is secured by the first holding element to the portion of the outer wall defining the inflated region for forming an inwardly extending pocket.
