A dental prosthesis for periodontal integration is disclosed. Furthermore a customized dental prosthesis for osseointegration is disclosed having a first manufactured portion shaped to substantially conform to the three-dimensional surface 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 a tooth to be replaced. Furthermore a customized manufactured splint is disclosed to position and fixate a tooth-shaped prosthesis. Furthermore a CAD/CAM based method of and a system for manufacturing a customized dental prosthesis replacing an extracted tooth is disclosed, where the extracted tooth is scanned regarding its three-dimensional shape and substantially copied using (a) an imaging system in-vitro like a 3D scanner or in-vivo like a cone beam CT system, (b) CNC machinery and (c) biocompatible material that is suitable to be integrated into the extraction socket and at least partially adopted by the existing tissue forming the socket.

The present invention relates to a polymeric implant, especially useful for dental medicine. More specifically, the present invention relates to a polymerizable device comprising an artificial tooth's root and an abutment anchored therein and to a kit comprising interalia the same. The present invention also relates to a method for implanting the implant in the alveolar bore of previously extracted tooth.

A personal identification method using a digital image of teeth of a person to be identified including constructing a database by storing teeth images from a plurality of persons and at least one corresponding teeth characteristic element of each person; determining a position of an interline between an upper teeth portion and a lower teeth portion from an inner mouth area that is separated from a teeth image of the person to be identified, and isolating an upper teeth area and a lower teeth area based on the position of the interline; identifying one or more teeth characteristic elements from the upper and lower teeth areas; and searching the database based on the identified one or more teeth characteristic elements and determining identification pass or fail according to a similarity between the teeth image of the person to be identified and a teeth image retrieved from the database.

Methods and apparatus for recovering dental pulp from dentition of a donor are disclosed, wherein the pulp from within extracted teeth utilizing such methods and apparatus is harvested, while preserving a sterile environment and avoiding trauma and infection, and stem cells, dendritic cells, and other cells isolating from the pulp, and the various cells propagated and expanded for subsequent use in repair or regeneration of tissues of the body, for therapeutic treatments, and other medical purposes.

A method for constructing a panorama of teeth arch with elements of interest emphasized, comprising the steps of: extracting a teeth arch from a volumetric image; unfolding the extracted teeth arch into a panoramic ribbon; assigning weighted priorities to at least two points in the panoramic ribbon, wherein priorities are weighted higher for points inside or proximal to elements of interest and applying a weighted summation in a direction perpendicular to teeth arch resulting in the panorama with elements of interest emphasized.

The invention relates to an orthodontic accessory planning method for extracting features based on an oral voxel model. The method comprises the following steps: for input three-dimensional tooth point cloud data, extracting tooth point cloud global features through a feature extraction module by using a deep neural network architecture, obtaining category information of attachments on each tooththrough a multi-label classification module, and training through two modes of independent training and packaging training; and inputting actually obtained three-dimensional tooth point cloud data byusing the trained deep neural network structure, and giving category information corresponding to appliance accessories needing to be bonded by individuals. The orthodontic accessory planning strategysuitable for the individual can be obtained according to the tooth characteristics, the implementation process is easy and convenient to operate, the deployment cost is low, an effective reference basis is provided for a doctor to plan a diagnosis and treatment scheme and design an appliance, and therefore the working efficiency of the doctor is improved, and the accessory selection accuracy is improved.

The BioRoot® anatomic endosseous dental implant begins as a block of yttria-stabilized, zirconia oxide (MOL3% Y3ZrO2) that is milled and processed into a single piece dental implant with a custom built abutment to which a dental prosthesis can be attached after a three to four month osseointegration period, with unique retention devices that can be round, ovoid, or oblong-shaped, of any size desired with a varied number of holes (See Drawings FIGS. 1, 1 and 2, FIGS. 2, 1 and 2, and FIGS. 3, 1 and 2) which through the osseointegration process will become anchors between the implant surface and the alveolar walls of the extracted tooth root socket that minimize bone resorption, increase bone-to-implant contact, increase initial implant stability and enhance overall osseointegration.

The present invention relates to a processing method for bone graft material using teeth by separating an extracted tooth by region and processing the extracted tooth to allow regional powders to be independently used or mixed depending on a use such as graft material comprises the following steps: (a) cutting a tooth extracted from a patient at the boundary between the dental crown and the dental root of the tooth; (b) removing the missing region of the horizontally cut dental crown of a tooth, soft tissue and pulp tissue; (c) quick-freezing the tissue of the dental crown and pulverizing the same to prepare a powder having an average diameter of 200-1,500 μm; (d) degreasing the powder; (e) dehydrating the powder; and (f) carrying out a post-process including at least a sterilization with respect to the degreased and dehydrated powder to prepare a bone graft material.

A dental trap is provided for use in a mouth cavity of a patient during a dental procedure. The dental trap may separate the patient's mouth cavity from the patient's throat to prevent an extracted tooth and/or a dental tool, such as a screw, in the mouth cavity from falling into the throat. The dental trap may also allow the patient to breathe through the dental trap.

The invention discloses an auxiliary instrument for extracting teeth and relates to an auxiliary device for extracting teeth. The device comprises a base and spherical hinges with clamping seats, wherein a rotary connection rod a and a rotary connection rod b are arranged on two sides of the upper end of the base respectively; each of the rotary connection rod a and the rotary connection rod b comprises a vertical rod and a horizontal rod; the upper ends of the vertical rods are vertically connected to the horizontal rods; the vertical rods of the rotary connection rod a and the rotary connection rod b are connected to the base via the spherical hinges with the clamping seats respectively; the rotary connection rod a and the rotary connection rod b are capable of rotating up, down, left and right on the spherical hinges with the clamping seats; a support frame is arranged at one end of the horizontal rod of the rotary connection rod a or the rotary connection rod b; an arc-shaped plate is arranged at the upper end of the support frame; vertical plates are arranged on two sides of the upper end of the base respectively and are located at the inner sides of the rotary connection rod a and the rotary connection rod b; a gap between the vertical plates on two sides corresponds to the width of a dental operating table pillow; a plurality of threaded holes corresponding to a dental operating table are formed in each vertical plate.
