Abstract: A dental attachment assembly and method anchors a dental appliance with an implant and has an abutment member attached to the implant, a retention member in releasable snap engagement with the abutment member, and a cap secured in a recess of the dental appliance and in releasable swivel engagement with the retention member to position and secure the dental appliance onto the implant. The cap includes a cavity with a rounded, concave inner surface which engages with the retention member, an interior top surface of the cavity with a concave recess extending radially along an outer periphery of the interior top surface of the cavity to allow for rotation of the retention member within the cap. A central portion of the interior top surface of the cavity surrounded by the concave recess therefore protrudes vertically into the cavity to minimize vertical displacement of the retention member as it rotates.

The implant can have at least one variable profile helical thread that extends along the tapered region. The implant can have also micro-threads below the main threads, a gradual compressing tapered core, a self drilling apical end and a narrow coronal region.

Abstract: A dental implant is provided, wherein the dental implant includes a dental root implant. The dental root implant forms a columnar body, and two ends thereof have a tubular portion and a joint portion, respectively, wherein the tubular portion is provided with a plurality of through holes. A central groove is formed inside the tubular portion and communicates with the through holes, wherein an inner diameter of the central groove tapers from approaching the joint portion to away from the joint portion. The joint portion can be coupled to a dental crown, and the tubular portion can be coupled to a human alveolar bone. The through holes can facilitate an osseointegration of the dental root implant in the alveolar bone.

Abstract: A system for dental implant restoration is provided. It includes universal aligning adaptors and prosthetic components having co-operable indices, which together form a translational, integrating system which aligns, synchronizes, and references the prosthetic components about an implant's central axis of rotation. Rotation of an adaptor about a prosthetic component, with its reference point becoming aligned to a predetermined reference point on the prosthetic component, followed by the rotation of the adaptor/prosthetic component assembly about the implant, situates the prosthetic component in a predetermined position such that all other prosthetic components become synchronized to the adaptor's reference point. The prosthetic component is mechanical for clinical or lab bench use, or is virtual for restoration design in a software program, prior to milling prosthetic abutments or devices.

Abstract: Method and apparatus for fabricating an oral appliance are described for correcting malocclusions on a dentition of a subject. A three-dimensional representation of the dentition may be captured and a free-form structure having a lattice structure which matches at least part of a surface of the dentition is generated. The lattice structure defines a plurality of open spaces such that the free-form structure is at least partially transparent. The lattice structure may then be manufactured by impregnating or covering a coating into or upon the lattice structure such that the oral appliance is formed.

Abstract: A process for providing a sterilized dental article, at least a portion of the surface of which exhibiting a contact angle of less than 45°. The process includes the subsequent steps of a) providing a dental article and b) subjecting the initial dental article to a hydrogen peroxide plasma treatment. It is characterized in that the hydrogen peroxide plasma sterilization treatment of step b) is carried out in the presence of a carbon-containing compound, which during treatment is converted to form a carboxylic group attached to the surface of the dental article.

Abstract: The disclosure relates to an orthodontic bracket including a ligating member mountable to a bracket body, the ligating member moveable between an open and closed position over an archwire slot. The orthodontic bracket includes a channel formed between the bracket body and the ligating member, and a resilient biasing member extending into the channel, the biasing member interacting with the ligating member to retain the ligating member in either the open or closed position.

Abstract: Example dental scanning methods for analyzing jaws of a patient involve taking multiple scans of the jaws, and/or models thereof, and then shifting the image of one scan to match that of another. In some examples, fiducial markers are attached to the patient's jaws beforehand to accurately identify and track the relative position of the jaws. The methods provide a way for creating a precise image of an upper jaw and a lower jaw in their proper bite registration, even though the resulting image may show an insufficient number of teeth to readily do so. The final, properly shifted image serves as a virtual 3D jaw model that can be manipulated and analyzed to aid in various orthodontic and other dental treatments.

Abstract: A dental implant guiding tool set and a dental implant guiding sleeve thereof are disclosed. The dental implant guiding tool set includes a handpiece, a dental implant guiding sleeve and a tooth mold fastening device. The dental implant guiding sleeve includes a handpiece head guiding hole disposed axially and corresponding to a shape of the handpiece head of the handpiece, a lateral opening disposed on a side of the handpiece head guiding hole and corresponding to a connection handle of the handpiece. The dental implant guiding sleeve can directly guide the handpiece head of the handpiece, to prevent the dental implant guiding sleeve from directly contacting the drill bit mounted on the handpiece. Therefore, a conventional drill bit can be directly used for a guiding dental implant operation, and the minimal required operation space of the dental implant guiding tool set can be reduced.

Abstract: Protrusions or holes with jagged edges formed on the lingual side of invisible aligner trays are provided. The protrusions or holes irritate the tongue causing it to retract away from the incisors thus eliminating intruding force otherwise exerted by the tongue. A clear corrugated material is provided which is suited for making the aligner trays having the protrusions which otherwise would be difficult with standard thick material used. The lingual side protrusions are added by computer to the impressions taken from a patient's teeth such that the protrusions are formed on the dental model used to make the aligner trays.
