摘要：
The invention relates to a contra-angle for implantology or surgery with a head for holding and rotating an instrument about its longitudinal axis, and a handpiece containing, in a non-limiting manner, a connection providing the connection with an external motor drive, and a reducing assembly with an output gear. The contra-angle is formed of removable subassemblies, and principally of a subassembly called the intermediate support, including an input gear meshing with the output gear of the reducing assembly and an end gear mounted on the same rotating shaft and inside a hollow cylindrical body. The intermediate support is mounted so as to slide freely along an axis inside a central part of a head body and enabling positioning in the head and rotational driving of a removable head cartridge, when all the subassemblies are mounted together to form the contra-angle.
