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.

Provided is a technique of allowing a dental implant to be stably placed after extraction, to be accurately placed in a tooth extraction socket, and to be stably placed in the tooth extraction socket according to implantation position and angle. A method of manufacturing a scaffold for treatment of a tooth extraction socket and implantation of a dental implant includes receiving dental implantation information of dental CT data which is previously input via a terminal of a manager; manufacturing, by using a three-dimensional (3D) printer, a 3D model comprising alveolar bones and teeth, which are distinguished therebetween, based on a medical image file that is a medical image file (DICOM file) of the dental CT data; performing virtual tooth-extraction by removing, from the manufactured 3D model, a region corresponding to a tooth in a tooth-extraction target area; and manufacturing, by using the 3D printer, a scaffold to be placed in an actual tooth extraction socket according to a shape of a tooth extraction socket that exists in the manufactured 3D model as a result of the virtual tooth-extraction, wherein, when the scaffold is manufactured, image data of the scaffold is amended to allow a guide hole for implanting the dental implant to be formed in the scaffold based on the dental implantation information.

A dental prosthesis is provided which is formed of a crown portion and a partial root portion. The prosthesis is more substantial than traditional crowns, and is sized and configured to fit closely within a root hole left from an extracted tooth. The partial root portion is able to be directly abutting the tissue of the patient, and does not rely on any other framework such as a portion of existing tooth, bone graft, and the like. An implant may be positioned through a channel defined in the prosthesis and the prosthesis may be installed at the same time as the implant.

Employment of a lattice structure modelling approach in the design and manufacture of root analogue dental implants enables creation of implants of fully latticed character that maintains load-bearing properties without yielding, while also decreasing stiffness and improving surface design to accelerate bone healing. A novel methodology, that is at least semi-automated, takes into account individual patient data from an initial scan of a patient tooth or tooth root and generates a fully latticed root analogue with optimal mechanical properties and internal and surface features, implemented through additive manufacturing. This denotes innovative advancement over existing approaches to root analogue dental implant, and also offers a solution to dental implantation cases that cannot be resolved by traditional methods.

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.

A dental implant for supporting periodontal tissue and the supporting bone is provided. The dental implant includes an implant member with inner canal for insertion into a periodontal bone socket, and an anchoring assembly. The anchoring assembly includes a first fastening element and radially equidistant cylindrical members. The first fastening element engages the implant member within the hollow axial cavity. The root section includes through-holes for radially and forcibly sliding the cylindrical members through them. When the first fastening element apically advances within the hollow axial cavity, the cylindrical members generate an anchoring force to anchor the dental implant.

A method is disclosed, for preparing a dental prosthesis. The method comprises performing a first scan of a plurality of scannable temporary abutments comprising the respective scannable member arranged on a respective dental implant. The method comprises performing a second scan of an interim prosthesis arranged on the plurality of scannable temporary abutments comprising the respective scannable member. The method comprises generating, using a computer aided design, CAD, software, a model of a final prosthesis based on the first scan and the second scan.
