The invention relates to a method for the preparation of a glass ceramic or a glass, which comprise cerium ions and are suitable in particular for the preparation of dental restorations, the fluorescence properties of which largely correspond to those of natural teeth. The invention also relates to a glass ceramic and a glass which can be obtained using the method according to the invention, the use thereof as dental material and in particular for the preparation of dental restorations, as well as a glass-forming composition which is suitable for use in the method according to the invention.

A device for treating an artificial bone implant with blood, the device comprising: a container configured to accommodate an artificial bone implant and be filled with blood, wherein the container comprises an opening and a cover configured to cover the opening of the container. Additional embodiments of the device and methods for using the same are disclosed herein.

The present invention relates to an implant unit, particularly, a dental implant unit for mitigating impact which may be substituted for a natural tooth, the dental implant unit including: a crown; an abutment which has one side coupled to the crown; and a fixture which is coupled to the other side of the abutment, in which at least one of the abutment and the fixture has an elastic layer that is cut out in one direction, and also relates to a dental implant unit including: a crown; an implant structural body which has one side coupled to the crown, and the other side implanted from a gingiva to an alveolar bone, in which the implant structural body has an elastic layer that is cut out to have multiple layers.

A composition includes granules in which zirconia particles are aggregated. The granules have an average circularity of 0.81 or greater based on a projected image. Additionally, a layered body includes a first layer and a second layer that comprise granules and are adjacent to each other. The granules in the first layer have an average circularity of 0.70 or smaller based on a projected image. The granules in the second layer have an average circularity of 0.92 or greater based on a projected image.
