Orthodontic palatal and jaw expansion device

A palatal and jaw expansion device comprising:

• at least one screw;
• at least two blocks, including a first end block and a second end block, that are positioned respectively on a first end and a second end of the screw to move on the at least one screw;
• at least one stabilization rod on which the at least two blocks are also seated;
• a movement mechanism disposed at the center of the screw;
• an arm that has a fixed end fixed to the movement mechanism perpendicularly to a horizontal axis where the at least one screw extends, when force is applied on a free end, of the arm, it rotates the movement mechanism on which the arm is fixed and the screw around the horizontal axis where the screw extends, enabling the at least two blocks to move on the screw;
• a first gearwheel that is disposed on the movement mechanism, whereon teeth in various profiles are bored, whereto the arm is fixed and that rotates on the screw around the horizontal axis by the movement of the arm;
• and
• a second gearwheel that is fixed on the screw, between the first gearwheel and the second end block, that completely contacts the first gearwheel to shift to an active position by the movement of the first gearwheel, and whereon teeth in matching form with the teeth on the first gearwheel are provided;
• a first set and a second set that are disposed on the screw and that respectively limit the first and second gearwheels from both sides;
• a channel which is provided between the second set and the second gearwheel;
• two protrusions which are oppositely provided on the stabilization rod, which extend towards the movement mechanism and the screw, with one thereof being fitted into the channel and the other remaining between the second set and the second end block and
• a first stopper which is provided on both ends of the stabilization rod and that prevents the palatal jaw expansion device from disassembling.
