Abstract: System and method for developing a treatment plan for achieving a treatment goal including creating a virtual model of a dental patient's dentition; transforming the virtual model of the dentition using virtual prosthodontics to facilitate achievement of the treatment goal; transforming the virtual model of the dentition using virtual orthodontics to facilitate achievement of the treatment goal; iterating on the transforming steps until substantially achieving the treatment goal; and generating an orthodontic treatment plan and a prosthodontic treatment plan based upon the substantially achieved treatment goal.

Abstract: The invention relates to a specimen part for creating a stress-free fit, a so-called passive fit, of implant-supported and/or abutment-supported bridges and bars by means of a CAD/CAM tool for the creation of restorations, and to a method for creating a restoration from a digital model of a patient's jaw provided with at least two implants and/or abutments. The model is determined by means of an intraoral scan. In order to improve the precision of restorations and to shorten the production process, provision is made that the specimen part per implant and/or abutment has a scannable structure, preferably at a defined distance and angle to the implant and/or abutment.

The shaft portion is inserted into a cortical bone or penetrates through the cortical bone and is inserted to a position reaching a cancellous bone at an inner side of the cortical bone. The inflected portions are inflected to radial direction outer sides from one end portion of an axial direction of the shaft portion, and are exposed at a surface of the cortical bone. The exposed portion includes a portion that extends to the radial direction outer side from the one end portion of the axial direction of the shaft portion, and is exposed at the surface of the cortical bone.

Abstract: An implant formed by two implants: an upper implant and a lower implant, the upper implant being removable. The implant differs from conventional implants in that the body of the implant has a second polished collar corresponding with the beginning of the lower implant. The two implants are connected by a screw located in the lower part of the upper implant of which it forms a part, the screw engaging with the thread of the lower implant. The connection between the two implants is circular, as it must allow anticlockwise rotation when removed.

Abstract: A fixed, detachable dental attachment device has a cap for securing a dental appliance, a ring, and an abutment to attachment to a tooth root or implant. Also described herein are methods of securing a dental appliance in a subject's mouth by means of the dental attachment device. Further described herein is a dental attachment device for immediate load on a provisional denture and then incorporated into the final restoration.

Abstract: A series of at least three abutments for dental use and a method for selection and aligning an abutment therefrom in a patient mouth. The series comprises at least three abutments. Each abutment composes a mate of a polygonal rotation preventive adapter having an axis of rotation perpendicularly to a lateral cross section, and a support member extending from a proximal end of the mate and having rotational symmetry to the axis of rotation. A projection of the support member on a plane of the lateral cross section in at least one abutment, is asymmetric with respect to angle bisectors and medians of the polygonal shape. An angle between a straight line extending from the axis of rotation to a reference point on a projection circumference of the support member forms a unique offset angle with a side of the polygonal shape per each dental abutment in the series.

Abstract: The present invention is a surgical guide for guiding the insertion of a dental implant into a desired location in a patient's mouth. The implant includes a non-rotational structure. The surgical guide includes a structure and a master tube. The structure has a negative impression surface to be fitted on and placed over gingival tissue, bone, and/or teeth in the patient's mouth. The structure includes an opening through which the dental implant is placed. The master tube is located at the opening. The master tube includes indicia for alignment with the non-rotational structure on the implant such that the non-rotational structure of the implant is at a known angular orientation with respect to the master tube. The present invention includes kits of various components used with the surgical guide and with the dental surgery using the surgical guide.

Abstract: An orthodontic correction device includes a masticatory unit with a rigid body. The masticatory unit can be removably worn on a dental arch and does not deform when accommodating misaligned teeth. A recess is formed in the masticatory unit to accommodate a tooth of the dental arch which requires orthodontic correction. A guiding groove is formed on the occlusal surface of the masticatory unit. An elastic member is configured to stretch across the occlusal surface of the masticatory unit, retained in the guiding groove, and coupled with several connection parts affixed to the buccal surface and lingual surface of the tooth. Occlusal loading generated during mastication is transmitted to the teeth of the dental arch through the masticatory unit and activates the elastic member to move the tooth to its desired position. The orientation of the guiding groove determines the moving direction of the tooth.

Abstract: The present invention relates to a dental implant and a replacement ring. The dental implant has an insertion portion for anchoring in a jaw bone.

The sheath element has a, for example, generally elongate shape and a longitudinal bore defining a longitudinal opening reaching from a proximal end of the sheath element into a distal direction, and a plurality of holes in a wall of the opening. Further, the device includes a liquefiable element that is insertable or inserted in the longitudinal opening and at least partly liquefiable by the impact of energy impinging from the proximal side.

Abstract: 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.
