A method of making an all-zirconium one-piece dental implant has: oral scanning after implantation of artificial tooth roots, 3D archiving, making temporary dentures, and making integrated permanent dentures. The oral scanning is executed by an optical scanner and generates a digital file of a denture model, a five-axis processing machine makes a temporary denture according to the digital file of the denture model to provide fitting information to modify the digital file of the denture model or make a permanent denture. Making the permanent denture with an all-zirconium material without metal support comprises the five-axis processing machine forming a through hole in the permanent denture.

A system and a method for providing a model of a superstructure joining a denture and a corresponding dental arch, the method includes the steps of obtaining a first 3D representation of at least a part of a preliminary model of the denture, obtaining a second 3D representation of at least a part of the dental arch comprising dental implants, and generating a model of a superstructure based on the first 3D representation, the second 3D representation, dental implant positions and dental implant orientations.

In a shell for adapting a retention element to an anchoring element, and a method of forming a further retention element on an anchoring element including a shell, the shell has an internal cavity, the dimensions of which are matched to the external dimensions of the retention element and which is connectable to the retention element in an integral or form-fitting manner, and has an outer surface which is formed as a further retention element.

A virtual model of an intraoral cavity is provided, wherein this process is initialized by a dental clinic, and the design and manufacture of a suitable dental prosthesis for the intraoral cavity is shared between a dental lab and a service center.

An implant abutment capable of stably adjusting vertical dimension of occlusion, the implant abutment comprising: an upper coupling portion that is an upper portion coupled to an artificial tooth; a lower coupling portion that is a lower portion coupled to a fixture; an exposed portion that is a portion exposed to the outside between the upper coupling portion and the lower coupling portion, and an adjustment groove that is formed on an outer circumferential surface of the upper coupling portion and inwardly recessed in the upper coupling portion. According to the implant abutment capable of stably adjusting vertical dimension of occlusion of the present invention, although the abutment has a low upper coupling portion, it can maintain stable coupling with the artificial tooth, thereby ultimately ensuring ease of adjusting a height of the abutment.

Methods of manufacturing dental prosthesis/implants each to replace a non-functional natural tooth positioned in a jawbone of a specific pre-identified patient are provided. An example method includes the steps of receiving imaging data such as x-ray image data and surface scan data of a dental anatomy and/or a physical impression of the dental anatomy of a specific preidentified patient. The steps can also include forming a three-dimensional virtual model of at least portions of a non-functional natural tooth positioned in the jawbone of the specific pre-identified patient based on the imaging and surface scan data, virtually designing a dental implant based upon the virtual model, exporting the data describing the designed dental implant to a manufacturing machine, and custom manufacturing the dental implant for the specific patient.

Mechanisms for securing an abutment, removable prosthesis, and/or a fixed prosthesis to an implant without screws or cement are provided. At least a portion of an abutment and/or a fixed prosthesis may be formed from a resilient material to enable the abutment and/or the fixed prosthesis to be secured to secured to the implant without screws or cement. Alternatively, a removable prosthesis may include a spring-loaded snap fastener for securing the removable prosthesis to an implant without screws or cement. The spring-loaded snap fastener may include a metal coil having at least three turns disposed in a same plane. The spring-loaded snap fastener may secure the removable prosthesis to the implant by at least gripping a groove disposed at least a partially around an interface between the removable prosthesis and the implant.

In order to improve the reliability of a dental restoration, a method of implanting the dental restoration is provided. The method includes virtually disposing a virtual implant selected from a digital library on the basis of a CT image to correspond to an implantation information, and a virtual implanting guide sleeve, which is virtually and concentrically disposed to be spaced upward from an upper end portion of the virtual implant by an offset distance, and a scanning image overlap and are integrally stored; and generating design information of a surgical guide, wherein a virtual coupling hole corresponding to an outer circumference of the virtual implanting guide sleeve is formed in the design information.

A dental bar is disclosed for accurately determining the separation and relative orientation of two coping cylinders projecting from dental implants in a patients mouth to receive a prosthesis. The dental bar comprises two sockets, for fitting over and securing to the two coping cylinders, connected to one another by a limb formed of telescopically collapsible sections. The telescoped ections of the limb are of differing cross-sectional shape so as to define between them a volume into which a bonding material may be injected through a port, in order to lock all the limb sections permanently relative to one another.
