A unique CAD subtract body intended to create a design of a mating surface for a veneering overlay and a dental implant framework wherein the unique CAD subtract body is derived from a diagnostic wax-up surface model. The diagnostic wax-up surface model is created from at least one of scanning a diagnostic wax up or denture tooth set up, CAD models in a virtual set up, an intraoral scan of a diagnostic wax up or denture tooth set up taken in a patient's mouth, a CT scan or series of CT scans of a patient's mouth, a CT scan or series of CT scans with the use of a radiographic stent in a patient's mouth, and wherein the unique CAD subtract body can be used to create the tool path for the manufacturing of the veneering overlay and allows for the fabrication of a dental implant from at least one of a metallic material, a ceramic material, an acrylic material, a biocompatible material.

Method and prosthetic system for producing a substitution bridge structure with prosthetic teeth (6), for replacing an existing bridge structure (2) which is mounted on a base structure (1), wherein the base structure (1) is fixed to implants (10) by means of base screws (11) and the head (15) of the base screws (11) has a screw hole. A scan body is fixed to the head (15) of the base screws (11) and an intraoral scan of the oral cavity is executed and the scan data is related to a 3D digital model of the base structure (1) and/or of the existing bridge structure (2), wherein subsequently a 3D digital model of said substitution bridge structure is designed.

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 first guide member includes a horizontal body portion and a pair of upright portions. The horizontal body portion has an arcuate configuration and includes a first horizontal surface, a front surface, a rear surface, and a second horizontal surface. The first horizontal surface is flat. The first upright body portion includes a first inwardly extending portion. A first engagement surface of the first inwardly extending portion is configured to rest on a ridge of the alveolar arch of the patient. The second upright body portion includes a second inwardly extending portion. A second engagement surface of the second inwardly extending portion is configured to rest on a ridge of the alveolar arch of the patient. The first guide member lacks a component configured to extend along a lingual or palatal side of the alveolar arch of the patient.

The present invention relates to a system and method for dental implant and restorative services. By locating the key functions at one physical location, dental implant services are efficiently provided to patients. These functions include a treatment coordinator, a direct marketer, a restorative doctor/prosthodontist, a surgeon, an imaging area, and a dental laboratory, Further, services for dentate patients are improved by utilizing advanced dental implant methods and systems. These methods and systems include both model-based services and CT (computed tomography) guided surgery services. Using these services, improved surgical guides for dental implants are constructed.

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.

A dental attachment assembly is provided, including an abutment member and a male member. The abutment member may include an outer locating surface portion having at least two axially spaced retention portions having two generally rounded, annular projections. The male member for engagement over the outer locating surface of the abutment member may include an upper end and a continuous, unbroken skirt having a rounded, convex outer surface. The male member may be constructed from a rigid material and have at least two axially spaced, snap engaging formations on the inner surface of the skirt for snap engagement with the respective retention portions of the abutment member.

A dental implant includes an insert element of a titanium-based material inserted and soldered into a blind hole in an anchoring element of a ceramic. The insert element has spacer members to center it in the blind hole, with a uniform circumferential gap space relative to the anchoring element. A portion of the insert element protrudes outwardly beyond an end face of the anchoring element. The blind hole is partly filled with a glass solder, and the insert element is inserted into the blind hole, whereby some of the glass solder is displaced out of the gap space onto the end face of the anchoring element and the protruding portion of the insert element. A thermal soldering process secures the insert element into the anchoring element. The protruding portion of the insert element and remaining excess solder are removed to form a planar surface.
