An improved denture system is disclosed. An improved denture system has a support bar and a denture material blank. The denture material blank has an oversize cutout to secure the support bar. The support bar has oversized implant interfaces and optional oversized tooth abutments. After securing the support bar in the denture material blank the final shape and dimensions of the implant interfaces and optionally the final shape and dimensions of the tooth abutments will be machined. The denture system will result in an accurate reference and registration between the denture teeth and base and the implant interfaces

Dental implant with a base body made of ceramic anchorable in a jawbone and an implant superstructure attachable to the base body using a screw, wherein in an assembled state of the dental implant, a threaded portion of the screw engages with an inner thread formed in a blind hole of the base body, wherein the implant superstructure is by the screw pressed against the base body and wherein the engagement between the threaded portion of the screw and the internal thread of the blind hole occurs only in a lower half of the base body facing away from the implant superstructure.

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 superstructure support for disposition between an implantation body and a crown of a prosthetic tooth replacement includes a crown supporting area with an upper engagement structure or supporting the crown and a lower area facing the implantation body and having a smooth microstructure surface provided with webs and grooves extending around the superstructure support and acting as bacteria barrier between the gum of a patient and the superstructure support when mounted onto the implantation body installed in the jawbone of the patient.

A processing target mold is usable to form, by molding, a processing target to be shaved by a shaving device. The processing target includes a hold portion held by the shaving device, a target portion to be formed into a post-shaving item, and a coupling portion coupling the hold portion with the target portion. A main body of the processing target mold includes a bottom member, an outer frame member extending upward from the bottom member, and a protruding member extending upward from a portion of the bottom member that is enclosed by the outer frame member as seen in a plan view. The main body includes an injection space enclosed by the bottom member and the outer frame member. A material is injected into the injection space. The injection space includes a hold space, a target space and a coupling space in which the hold portion, the target portion and the coupling portion are respectively formed by molding.

A resin block that can be favorably used for obtaining dental prosthetics through the milling work, containing very little voids, having excellent property for being cut, exhibiting excellent appearance and mechanical strength, and without permitting the formation of defective products. The resin block contains a thermoplastic resin having a fluidizing temperature in a range of 310 to 500 C. and inorganic particles in an amount of 30 to 150 parts by mass per 100 parts by mass of said thermoplastic resin. The inorganic particles are at least one kind of inorganic oxide particles selected from the group consisting of silica particles, silica composite particles of silica and other metal oxides, titania particles, and titania composite particles of titania and other metal oxides. The resin block has a thick portion of a thickness of at least not less than 5 mm, and does not contain any void whose length is not less than 1.0 mm.

Apparatus and methods for making dental prostheses including a matrix housing that has a plurality of interconnected walls, one of which defines an aperture. The matrix housing houses a dental model of a set of teeth, a wax model of a clasp, and a matrix that defines a sprue. The aperture provides access to the sprue. The matrix housing may be used with a cartridge for containing thermoplastic resin and a resin discharging device. The discharging device includes a body defining a through hole, a cartridge mount attached to the body, a ratchet push rod inserted through the through hole and including a plurality of teeth, a trigger pivotably attached to the body, and a drive tooth connected to the trigger and the body. The drive tooth cooperates with the teeth of the push rod to control the pressure asserted by the push rod to the cartridge.
