A dental prosthesis (1) with an angled inner bore (2) is proposed, formed by a first hole (7) and a second hole (26) connected by an angled connection area (29) formed with an angle between 0 and 180. An outer area (31) and side areas (32) of the angled connection area (29) form an elbow (40) devoid of protruding edges directed towards the interior of the inner bore (2). Said elbow (40) facilitates the insertion and extraction of a screw through the inner bore (2) during the assembly or disassembly of the dental prosthesis (1) on a dental implant. Some methods of manufacturing said dental prosthesis (1) are also proposed.

Provided is a denture fixing attachment including: a rod-shaped joint member, having an upper end for supporting a denture fixed thereto and a locking protruding portion protruding laterally from a lower portion of the joint member; and an abutment having a coupling portion formed in an outer surface of a lower portion thereof so as to be coupled to a fixture recess formed in the fixture, and a receiving portion formed in an upper portion thereof so as to receive the lower portion of the joint member therein, wherein the receiving portion of the abutment includes a receiving recess for receiving the lower portion of the joint member inserted thereinto, and a stop protruding portion provided in the receiving portion above the receiving recess and having a guide groove disposed adjacent to the stop protruding portion for guiding coupling movement of the locking protruding portion fitted thereinto.

A dental implant device in the form of an interface member for forming an individually customized dental implant abutment mounted on a connection platform of a dental implant anchor adapted to be implanted, the interface member is a hollow tubular member featuring an internal lumen defined between a non-customizable distal portion and a customizable proximal portion.

Molds for fabrication of custom and potentially modifiable abutments and impression posts for dental implants with various degrees of angulations (including zero degrees) and various dimensions are provided, with a generally oval shape that expands laterally upwards, a symmetrical or asymmetrical cross-section, and regular surfaces, that are fabricated as one piece, or as two coupling pieces snapping onto each other. Custom abutments achieve the development of a custom gingival emergence profile, three dimensionally, which is potentially modifiable according to the needs of each particular clinical case. Custom impression posts that correspond in dimensions and angulations to the abutments allow the accurate recording and transfer of the developed gingival emergence profile from the mouth onto the working cast, where the final implant prosthesis is fabricated. Custom abutments and impression posts have properties and design that allows their preparation and usage as temporary abutments for the cementation and support of temporary prostheses.

A method for correcting an angular offset of a dental prosthetic mounted atop an angularly-offset installed one-piece miniature dental implant having a ball-shaped head above a circular neck, includes steps of: (a) unseating the angularly-offset prosthetic; (b) removing a rubber O-ring disposed about the circular neck; (c) providing a replacement nylon cap and metal housing subassembly and incorporating the subassembly into a dental prosthetic cavity; (d) mounting the dental prosthetic upon the angularly-offset installed miniature implant; and (e) angularly translating the mounted dental prosthetic from a first offset angular orientation to a second non-offset angular orientation.

A fastening system (100) for a dental implant (30) comprising a ball shaped portion (31), wherein the fastening system (100) comprises a body (12) having a seat (10, 20) forming a cavity. The fastening system is characterized in that the body (12) comprises at least two parts (10a, 10b, 20a, 20b) together forming the seat (10, 20). The parts (10a, 10b, 20a, 20b) are arranged such that the seat (10, 20) can engage around the ball shaped portion (31) of the dental implant (30) and in that the seat (10, 20) is movable between a first position in which the parts (10a, 10b, 20a, 20b) are allowed to move relative each other, and a second position in which the parts (10a, 10b, 20a, 20b) are prevented from moving relative each other.

An interface element for dental prostheses, having a hollow cylindrical body with two different sections, one lower section (a) of greater outer diameter and another upper section (b) of smaller outer diameter, each provided externally with retention circular grooves (2). The element had an internal seat (4) for a screw head (5) which fixes the implant, and a lower base (6). A side mortise (7) is provided that covers the upper section (b) and provides a side opening for the inclined entrance of the screw (5) and screwdriver (8).

A set of rules to design an orthodontic appliance for generating an aesthetic smile is maintained in a computational device, where the set of rules is associated with an application that executes in the computational device. At least one measured value is computed from one or more features extracted by processing dental information of a patient. The application generates a parameter to design an orthodontic appliance based on the at least one measured value and the set of rules for generating the aesthetic smile.

Apparatus and method for installing a multi-tooth dental prosthesis in one session are shown and described. A first tool attaches to the jawbone, and serves as a foundation for subsequently used guides. Existing teeth and dental fixtures are removed, and the bone tissue is removed to accommodate the prosthesis. Subsequently, a drill guide is used to drill implant holes. An abutment guide is then used to place abutments. Copings are then installed. Next, the prosthesis may be installed and cemented to the copings. A resinous filler material may be applied to fill gaps and holes in and between the copings and the prosthesis, and is sanded smooth. The first tool, the guides, and the prosthesis are predesigned and prefabricated based on images taken of the patient anatomy.
