Abstract: Orthodontic expander including a left frame (T1) and a right frame (T2). The left frame (T1) and right frame (T2) respectively include a left body (1) and a right body (2) provided with structure for their anchorage to the teeth of a dental arch. The bodies (1.2) have through holes (10) oriented in an expansion direction (d). The frames (T1, T2) are slidingly mounted along the expansion direction (d) by guides (4) inserted in the holes (10) of the bodies (1.2). The distance (h) between the bodies (1, 2) is adjusted by a screw (5) screwed into the body (2) of one of the frames. The screw (5) has an operating head (51) positioned between the bodies (1.2) Elastic plates are positioned and acting between the frames (T1, T2) and can be activated or reactivated by acting on the screw (5) which compresses them to activate or reactivate them when desired.

Abstract: Tool for handling palatal expanders, including two opposed jaws adapted to clamp at least one body of a palatal expander, a handle, and actuation means adapted to move said jaws between a clamping position on said at least one body and respectively a release position, said jaws being bound elastically to one another and are normally spaced from each other, and said actuation means comprising a slider slidably mounted on the outer surfaces of the jaws, the slider being provided with a part adapted to interact with said outer surfaces so as to compress the jaws by pushing them toward each other when it is made to slide along a first direction and free them when it is made to slide along a second direction, said actuation means being adapted to firmly but reversibly lock the jaws in said clamping position.

Abstract: Self-activated orthodontic expander including a left frame and a right frame, where the left frame and right frame include, respectively, a left body and a right body, each having anchoring means for anchoring them to the teeth of a dental arch. The bodies have through holes oriented in a predetermined expansion direction, where the frames are slidably mounted along the expansion direction by guides inserted into the holes of the bodies. Elastic elements are arranged and acting between the frames. The guides are further constrained with each other by a bridge oriented orthogonally to the same guides and adapted to prevent the reciprocal movement of the guides.

Abstract: Expansion screw for orthodontics, comprising at least one stem (1) with at least a threaded portion (10) extending along the longitudinal extension of the stem (1), at least one receiving body (3) adapted for receiving said threaded portion (10) and provided with a complementarily threaded hole allowing said threaded portion (10) to be screwed therein, guide means (2) allowing said at least one receiving body (3) to be moved, actuation means (11, 12) for actuating said stem (1). The hole (31) of said at least one receiving body (3) has a longitudinal extension substantially corresponding to that of the threaded portion (10) of said at least one stem (1). The receiving body (3) is a technopolymer receiving body and the stem (1) is embedded in the technopolymer of the receiving body when the expansion screw (100) is made.

Abstract: A fan screw for the expansion of the upper jaw, including two bodies (1, 2) connected by at least one driving screw (4; 7) and placed on opposite sides with respect to a sagittal plane (x-x), the longitudinal axis (v-v; k-k) of the at least one expansion screw (4; 7) being perpendicular to the plane (x-x), each of the bodies (1, 2) having a lingual side (L1, L2) and an opposite upper side and being provided with a structure for anchoring it to several teeth of a dental arch destined to be expanded. The longitudinal axis (v-v; k-k) of the at least one driving screw (4; 7) is at a predetermined distance (h) from the lingual sides (L1, L2) of bodies (1, 2), the distance (h) being measured along a lingual direction (L) parallel to the plane (x-x), such that the distance between the axis (v-v) of the at least one driving screw (4; 7) and the upper sides of bodies (1, 2) is greater than the distance between the upper and the lower sides of bodies (1, 2).

Abstract: A surgical guide system for dental implantology has a plate (10) provided with a guide sleeve (2) delimiting a through hole with an axis oriented to a predetermined direction. A drill (4) for osteotomy has a spindle connected to a handpiece with drilling portion (41), the drill (4) being for association with the guide sleeve (2) during osteotomy. The diameter (d41) of the drilling head portion (41) is larger than the inner diameter (d2) of the guide sleeve (2) and the spindle is of smaller diameter, such that the association of the drill (4) to any of the guide sleeves (2) can be performed only by inserting the spindle through a gingival side of the sleeves. Upon association of the drill with the sleeve, the drilling head (41) protrudes from the gingival side (2G) thereof. The surgical guide has a void (100) accommodating the drilling head (41) of the drill.
