Abstract: Method for determining a position and an orientation of a dental implant includes scanning a surface of a scan body connected to the implant wherein a plurality of data points is determined which correspond to positions of points that are located on the surface of the scan body. The method further included reconstructing at least three planes based on the data points, reconstructing intersection information of the reconstructed planes, where the intersection information includes the reconstruction of straight intersection lines and of intersection points, and determining the position and the orientation of the implant based on the reconstructed intersection information.

Abstract: A process for providing a topography to the surface of a dental implant, the surface being made of a ceramic material having yttria-stabilized zirconia, the process including: providing a macroscopic roughness to the surface of the dental implant by a mechanical process and/or injection molding technique; and etching at least a part of the roughened surface, wherein etching is carried out using an etching solution having hydrofluoric acid at a temperature of 70° C. at least, such that discrete grains or agglomerates of grains are removed from the yttria-stabilized zirconia, thereby forming recesses and cavities in the roughened surface is disclosed.
Abstract translation: 一种用于向牙齿植入物的表面提供形貌的方法，所述表面由具有氧化钇稳定的氧化锆的陶瓷材料制成，所述方法包括：通过机械过程向所述牙科植入物的表面提供宏观粗糙度和/或 注塑技术; 并且蚀刻至少一部分粗糙化表面，其中使用在70℃的温度下使用具有氢氟酸的蚀刻溶液进行蚀刻，至少使离散晶粒或颗粒附聚物从氧化钇稳定的氧化锆中除去 从而在粗糙表面中形成凹陷和空腔。
