A dental prosthesis to be integrated into a jaw bone cavity of a pre-identified patient. An example of a dental prosthesis includes a first manufactured portion having a surface shaped to substantially dimensionally conform three dimensionally to an undersized shape of the outer three-dimensional surface shape of a root of a tooth to be replaced, and a second manufactured portion shaped to substantially conform to the three-dimensional surface of a crown of the tooth. The outer surface of the root portion can include or be coated with a biocompatible material that is suitable to be integrated into the extraction socket and adopted by existing tissue forming the socket.

A dental implant identification system is provided that aids a dental professional in identifying the type of dental implant that has been surgically placed into maid lary or mandibular bone of a patient who requires restorative dental procedures. Additionally, a dental implant identification system is provided. that aids a dental professional in identifying the forensic remains of victims due to various factors and circumstances.

A device for anchoring to the upper jaw bone dental prostheses of the upper dental arch using a plurality of intraosseous screws each provided with a thread and a bottom shank. A crosspiece with a plurality of nuts corresponding to the number of intraosseous screws are connected together by means of spacers, each nut having a female thread corresponding to the thread of a respective intraosseous screw. A lock nuts corresponding to the number of intraosseous screws are each provided with a female thread in turn corresponding to the thread of the respective screw. The crosspiece is designed to be inserted and housed, during use, in the maxillary sinus and the each screw is inserted inside a respective hole through the bone underneath the maxillary sinus so that it projects beyond the inner cortex of the bone and is inserted inside the respective nut of the crosspiece.

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.

An implant to retain facial or dental prostheses includes a bone-engaging portion, a transmucosal portion, and an abutment portion. The bone-engaging portion of the implant includes a longitudinally extending distal portion formed of a conformal microscale cell structure and, optionally, a non-biological coating. The transmucosal portion includes a plurality of micro holes. The abutment portion of the implant may be polished to a mirrored or super-mirrored finish.

Dental implant and superstructure each with an interface that allows direct attachment of the superstructure to the dental implant without the use of an abutment. The dental implant comprises an anti-rotation element that is arranged in the opening and is configured to prevent the superstructure from rotating about a longitudinal axis relative to the dental implant. The superstructure comprises an interface corresponding to the anti-rotation element, having a recess with two mutually opposite side flanks which are at a first distance from each other in a first region and, in a second region which is at a greater distance from the longitudinal axis than the first region, are at a second distance from each other, the second distance being smaller than the first distance.

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.

A root portion of a root-analog dental implant may include a core positioned in an approximate center of the root portion of the dental implant. The core may provide mechanical strength and/or support for the dental implant and may include one or more struts. The root-analog dental implant may further include a porous surface positioned on a portion of a vertically oriented exterior surface of the core. The struts may be configured and arranged to provide mechanical strength and/or support for the root-analog dental implant.
