The present invention relates to an implant unit comprising: an artificial dental root including a plate portion having a first side surface and a second side surface extending along the horizontal extending direction of the alveolar bone and opposed to each other, and a base portion protruding from the first side surface at the upper end of the plate portion, penetrating through a surface of the alveolar bone, and being implanted into the alveolar bone; and at least more than one abutment formed on the upper end of the base portion.

The present disclosure concerns a subperiosteal dental implant for receiving at least one replacement tooth of a patient, the subperiosteal dental implant comprising an implant frame superposable to at least a section of a jaw hone of the patient, the implant frame having a bone-facing surface at least partially contacting the jaw hone of the patient when the implant frame is superposed thereto, and an opposed gum-facing surface, the implant frame having at least a section along which a cross-section profile includes a base defining at least partially the bone-facing surface and at least partially the gum-facing surface, a ridge protruding from the base and defining at least partially the gum-facing surface, and a first shoulder and a second shoulder that are both defined on the gum-facing surface of the base, each one being located on a respective side of the ridge.

A dental prosthesis and a process for design and manufacturing, incorporating an overdenture and a dental implant framework that will be designed and manufactured simultaneously.

A method and device for developing a geometry of a superstructure and/or mesostructure for dental prostheses. According to one aspect of the invention a method of developing a geometry of a mesostructure for a dental prosthesis includes the following steps: receiving first 3D data defining a 3D installation space for a mesostructure, receiving second 3D data defining possible positions for attaching the mesostructure, receiving third 3D data defining possible positions or regions for attaching the dental prosthesis to the mesostructure, and developing an optimized geometry of the mesostructure by means of an optimization technique, wherein starting from the 3D installation space the possible positions for attaching the mesostructure and the possible positions or regions for attaching the dental prosthesis to the mesostructure, the geometry of the mesostructure is optimized by means of applying the physical laws.

An angled zygomatic implant apparatus for spanning a patient's zygomatic bone and maxillary bone includes a zygomatic abutment screw with a conical receptacle and san implant threaded bore, the zygomatic abutment screw is adapted for fixation in the patient's zygomatic bone, and an angled extension having an implant end adapted with a conical portion adapted for fixation to the conical receptacle of the zygomatic abutment screw. The angled extension is elongated and otherwise adapted to span the space between a patient's zygomatic bone and maxillary bone for fixing a maxillary tooth implant.

A bone foundation guide system having a bone foundation guide with a foundation guide body forming an open surgical space connecting a top of the bone foundation guide body with a bottom of the bone foundation guide body, the bottom contoured to removably affix the bone foundation guide body to the bone of a dental implant surgical site, the body further contoured to guide the cutting of bone from a dental implant surgical site and supporting a dental implant surgical guide; the dental implant surgical guide contoured to removably mate to the bone foundation guide body; wherein a combination of the bone foundation guide and the dental implant surgical guide forms a double open-ended placement channel that passes through a plurality of guiding cylinders held in tandem alignment to aid in the placement of a dental implant that is anchored in a site remote from the mouth.

A kit (1) for preparing a dental prosthesis, having a master model (2) manufactured by means of an additive technology using an arrangement of material in successive layers (3), such as 3D printing, and having a fixing screw (4) with an outer thread (4a) intended to removably fix a dental prosthesis element on the master model (2). The master model (2) has at least one reference surface intended to receive the dental prosthesis element bearing thereon, said reference surface being produced during the manufacture of the master model (2) by additive technology. The master model (2) has at least one threaded, cavity (6), of which the inner thread (6a), intended to receive said fixing screw (4) by screwing, is produced during the manufacture of the master model (2) by additive technology. The outer thread (4a) of the fixing screw (A) has a pitch (P) greater than or equal to 10 times the thickness (E) of the layers (3), and it has a thread height (H) greater than or equal to 5 times the thickness (E) of the layers (3).

A one piece custom made dental device for holding multiple teeth comprises a mono block of dental implants (4), abutments (1), supracrestally or supragingivally connecting bars (2) and pontics (3). Implant (4) is made up of flat and broad base (4.1) and implant body portion (4.4) having vertical threads (4.3), inverted thread (4.2), crestal supporting thread (4.5). Implant (4), abutments (1) and pontics (2) are fabricated according to an individual's bone and gum data to form mono block structure without any screw and joints in such a manner as to distribute stress and strain on integrated dental implants. Multiple implants are integrated through supracrystally or supragingivally connecting bars (2). The dental device of the present invention is designed to achieve faster placement and implantation process with minimal bone loss and minimal micro movements. The present device reduces time required for healing and cost of whole implantation and prosthesis process drastically.

A dental prosthesis and a process for design and manufacturing, incorporating a dental implant framework and veneering overlay that will be designed and manufactured simultaneously and permanently fixated to one another.
