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.

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 element 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.
