摘要： 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.

摘要： 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.

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： An orthodontic screw and a set of elements for forming an orthodontic or orthopedic appliance for dentistry, as well as a method for making an orthodontic or orthopedic appliance for dentistry. The orthodontic screw includes two bodies connected by positioning elements designed to allow the distance between the bodies to be adjusted; the bodies have a seat adapted to receive a portion of a connection structure associable with the orthodontic screw for its connection to the teeth of a dental arch; the seat has a groove formed on an external surface of the bodies, so that said portion of said connection structure can be inserted in the seat through a displacement orthogonal to the same seat.
