摘要： Orthodontic expander including a left body)and a right body provided with through holes oriented along a pre-defined expansion direction, a pair of guides inserted in the holes, and elastic thrust elements preloaded and acting between the bodies to provide a thrust directed in the expansion direction in the orientation of moving away of the bodies. The guides and the bodies have respective surfaces engaging with each other to limit the expansion of the elastic elements, limiting the sliding to a maximum predetermined sliding value such that the preloading of the thrust means is greater than zero at this maximum predetermined sliding value such that the thrust exercised by the elastic elements is greater than zero at the maximum predetermined sliding value.

摘要： 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.

摘要： Fan screw for the expansion of the upper jaw, comprising 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 said at least one expansion screw (4; 7) being perpendicular to said plane (x-x), each of said bodies (1, 2) having a lingual side (L1, L2) and an opposite upper side and being provided with means for its anchorage 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), said distance (h) being measured along a lingual direction (L) parallel to said 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).
