The present invention relates to a missing tooth supplementing dental prosthesis that may provide the best wearing comfort regardless of the condition of a user's gums as the height of an end of a missing tooth supplementing member is adjusted according to the condition of the user's gums. The present disclosure proposes a missing tooth supplementing dental prosthesis including: a prosthetic body configured to be detachably worn in the oral cavity of a user who has at least one missing tooth, and provided with a fastening portion that is formed in a portion corresponding to a missing tooth; and a missing tooth supplementing member configured to be height-adjustably coupled to the fastening portion of the prosthetic body, to be height-adjusted according to the condition of the user's gums, and to supplement the missing tooth as an embodiment.

Computer-aided design and manufacturing of removable partial denture frameworks with enhanced biomechanical properties

A method is provided for designing and fabricating a removable partial denture (RPD) framework including clasp retainers configured for removable engagement with abutment teeth of a patient. The method includes obtaining an initial digital model of the RPD framework based on patient image data. For each clasp retainer, a set of relevant geometric parameters is identified, each relevant geometric parameter being provided with a nominal value, and a target value of dislodging force is provided. The method further includes performing a force analysis on the initial digital model to determine corrected values for the relevant geometric parameters of each clasp retainer such that when the corrected values are assigned to the relevant geometric parameters, the dislodging force matches its target value. The method also includes obtaining a corrected digital model based on the corrected values, and fabricating the RPD framework based on the corrected digital model.

Integrated hybrid dental implant

The present invention relates to an integrated hybrid dental implant, and more particularly, to an integrated hybrid dental implant in which an opening portion formed at a screw body to enable a drug to be injected into an implantation site of the implant, and the mechanical stability is excellent despite the presence of the opening portion. The integrated hybrid dental implant according to the present invention enables a drug to be supplied to the area around the implantation site so as to induce bone regeneration into the implant after the implant has been placed at a bone-deficient site, has an additional mechanical strength when bone grows into the side openings and hollow inner channel, and allows the screw body to be integrally formed with the prosthesis section (i.e., one piece) to exhibit more excellent mechanical strength so that the implant can be useful as a dental implant.

The present invention relates to the field of dentures. More particularly, the present invention relates to manufacturing denture teeth using fixtures to hold the teeth during a scanning, registration and milling sequence. Even more specifically, the present invention relates to using machinable wax to set denture teeth within a fixture, so that the root or crown end of the teeth may be scanned, registered with an ideal tooth model to create a milling strategy, and milled or otherwise have material removed.

Cosmetic Facial Prosthesis and Methods for Making the Same
20210085432 · 2021-03-25 ·

The present disclosure relates to a cosmetic facial or maxillary prosthesis. The cosmetic facial or maxillary prosthesis is designed to be worn by individuals having certain physical deformities that affect the appearance of their face as a temporary cosmetic piece that provides an aesthetically improved appearance by softening and straightening certain facial imperfections. The cosmetic facial or maxillary prosthesis is fully functional in that it stays in place with normal movement of the user's mouth, for example, while talking, eating and chewing and does not interfere with daily tasks. The cosmetic facial maxillary prosthesis is not outwardly observable by others and may be removed by the user at any time.

DENTAL PROSTHETIC SYSTEM WITH A BRIDGE STRUCTURE THAT CAN BE REMOVED FROM A BASE STRUCTURE
20210205051 · 2021-07-08 ·

Dental prosthetic system with a base structure (1) and a bridge structure (2). The base structure can be mounted on implants (10) provided in the jaw, whereas the bridge structure (2) with prosthetic teeth (6) which can be fixed on the base structure (1) in a fitting and detachable manner. This bridge structure (2) has bores (8) for screws (12) to fix the bridge structure (2).

This system includes base screws (11) for attaching the base structure (1) to said implants (10), wherein the head (15) of these base screws (11) is provided with an screw hole for mounting the bridge structure (2) on the base structure (1) by means of bridge screws (12) provided to that end which can be fixed in the screw hole of the base screws (11).

DENTAL ANCHORING SYSTEM FOR FASTENING PROSTHESES

A dental anchoring system for fastening prostheses having a male component, a female component which is coupled to the male component, and a connection element which is coupled to the female component and makes up the retaining element of the prosthesis configured to be joined to the connection element. The dental anchoring system is configured to achieve a self-adjustable fastening of the prosthesis which enables the mobility of prosthesis to be controlled when it is subjected to a load during the use thereof by a patient; and wherein the mobility is limited by a ring-shaped stop of the female component, when at least one portion of a ring-shaped plane of the connection element comes into contact with ring-shaped stop of the female component.
