Bone expanding device for creating implant cavity by expanding jaw bones, has mechanical impulse valve with impulse head linked to actuation end of bone expander by coupling arrangement to transmit impulse to chisel end of bone expander

摘要

The device has a bone expander (1) that has a chisel end (2) for forming an implant cavity, and an actuation end (3). A mechanical impulse valve (6) has an impulse head (8) linked to the actuation end of the bone expander through a provided coupling arrangement (10) to transmit impulse to the chisel end of the bone expander.
