摘要： The invention relates to a method for the virtual post-processing of a first virtual three-dimensional dental model (14) of a dental prosthesis (28), said model having been created during the planning of the prosthesis (28). The first virtual dental model (14) is processed virtually after the planning stage in an additional method step (18, 31) by adapting at least one three-dimensional aesthetic surface structure (17) already in existence to the first dental model (14) by means of a virtual tool (10) with the aid of a computer (4) and a display device (6) and by subsequently inserting said structure into the first dental model (14). The aesthetic surface structure (17) has a predetermined form, size and/or a predetermined impression depth (41), and a tooth surface (19) of the dental model (14) is at least partially replaced by the adapted aesthetic surface structure (15, 17).

摘要： The invention relates to a method for recording individual three-dimensional optical images (1) to form a global image (50) of a tooth situation comprising an upper jaw (2) and a lower jaw (3). A first 3D model (6) of a first subsection of the upper jaw and a second 3D model (8) of a second subsection of the lower jaw are produced from the individual images. Subsequently, a geometric positional relationship between the first 3D model (6) and the second 3D model (8) is determined, said positional relationship being determined by using a lateral image (20, 21, 22) and/or using a contact pattern (31, 32). Said lateral image (20, 21, 22) comprises an image area which comprises at least part of the first subsection of the upper jaw (2) and at least part of the second subsection of the lower jaw (3). Said contact pattern comprises several contact areas (31, 32) between the upper jaw and the lower jaw. Said contact pattern (30, 31, 32) is measured by means of an occlusion paper (29).

摘要： In dentistry very often soft tissue has to be cut. It has become customary to cut soft tissue, in particular gum or gingiva, or to disinfect pockets in the gingiva that exist at the neck of teeth with the help of laser light. The same applies to a disinfection of the channel in the root of teeth (endodontic treatment). Prior art concepts of cutting soft tissue rely on the use of red or infrared diode lasers and lead to an excessive heating the tissue and damaging of surrounding tissue. We suggest a device for treatment comprising a laser diode with a wavelength of 445±15 nm, in particular 445±10 nm, for providing the laser light. The use of e.g. 445 nm for cutting soft tissues has numerous advantages.
摘要翻译：在牙科中，经常需要切割软组织。习惯上借助激光切割软组织，特别是牙龈或牙龈，或消除存在于牙齿颈部的牙龈中的口袋。同样适用于消除牙齿根部的通道（牙根治疗）。切割软组织的现有技术概念依赖于使用红色或红外二极管激光器，并导致组织过度加热并损坏周围组织。我们建议一种用于处理的器件，包括波长为445±15nm，特别是445±10nm的激光二极管，用于提供激光。使用例如用于切割软组织的445nm具有许多优点。

摘要： The invention relates to a method for validating a drilling template for producing an implant-borne tooth replacement before performing an implant drilling. The drilling template produced is placed on dental structures of a jaw area that is to be provided with the tooth replacement. A measuring element is inserted into the drill guide of the drilling template, wherein the measuring element and at least one partial region of the dental structures not covered by the drilling template is measured using an optical three-dimensional measuring method. Then the position and orientation of the measuring element in relation to the partial region of the dental structures are determined from the generated measured data of the optical measurement, wherein a virtual actual implant drilling model is created on the basis of the optical measured data using the position and orientation determined for the measuring element, and/or using the known dimensions of a drill to be used, and/or the position of a stop surface on the drilling template for the drill to be used, wherein the actual implant drilling model is compared with a planned virtual target implant drilling model from a previous implant planning with respect to its position and its orientation.
