Abstract: A computer-aided method for designing a surgical template for dental and/or orthodontic implants comprises acquiring a first 2D or 3D image of the oral cavity and of the overlying anatomical structures of a patient, processing the first image for defining one or more second 2D images showing corresponding views or sections of the oral cavity, realizing a digital model of the upper dental arch and of the palate of the patient to identify one or more suitable sites for inserting a corresponding implant, selecting one or more slices of the digital model at one or more sagittal or parasagittal planes passing through respective insertion sites, overlapping the slices with corresponding second 2D images for generating a third 2D image, providing a digital library of implants for the selection thereof and for their virtual positioning into the third image in order to allow the adjustment of the inclination and/or the deepness of insertion.

Abstract: The invention relates to an orthodontic screw with a self-ligating fixing system for orthodontic apparatuses with a filiform part comprising a head equipped with at least one longitudinal slot for the insertion of said filiform part, a threaded shank to be applied to the bone of the mouth and a stop means to reversibly block said filiform part. The stop means is a fork comprising at least two teeth and the head features at least one through hole made in one of the walls which delimit the slot, and said hole has a corresponding second through or not through hole in the opposite wall delimiting the slot and in which the axis that runs through both holes is located above the filiform part insertable in said slot. In addition, the invention regards a related system and an orthodontic kit comprising said screw.

Abstract: The invention discloses an anchor screw (10) to the palatal vault for orthodontic correction treatments comprising: a lower threaded portion (1) adapted to be screwed to the bone; a substantially cylindrical central portion (2) protruding from the bone and the gum adapted to allow anchorage of traction and/or thrust orthodontic devices; an upper portion (3) provided with movement means (4) to screw and unscrew the screw. The central portion (2) has a reduced diameter zone (6) in comparison with the diameter of the cylindrical portion and at least a hole (5) for the passage of orthodontic devices such as round and/or rectangular/square wires.

Abstract: The invention consists of an anchoring device to be applied in the palatal arch to anchor the wires suitable for orthodontic treatment. Said anchoring device consists of: the first screw (1) with a threaded shank (11; 12) topped by a substantially cylindrical collar (13), with non cylindrical head (14) of reduced width as compared to the diameter of said collar; said first screw has a threaded hole (15) coaxial to the axis of said first screw; a substantially cylindrical distance sleeve with two central hollows (62; 63), the first hollow (62) non cylindrical and with a profile suitable to mate with said collar (14) of said first screw. The second hollow (63) has a substantially cylindrical profile suitable to the passage of the shank (71) of a second screw (7). The second screw (7) has a head (73) topping said cylindrical shank and a threaded end part (72), where said head has a threaded hole (74) suitable for receiving said locking screw (10) of the cap (8).
