Abstract
Disclosed is a dental implant distractor, including an implant module and a traction module. The implant module includes an implant, a sealing screw, and a base body. The traction module includes a connecting screw rod, a traction screw rod, an inner sleeve, and an outer sleeve; the connecting screw rod is threadedly connected to the base body; the traction screw rod is located below the connecting screw rod; the inner sleeve is provided below the base body. This apparatus can automatically complete the installation of the base body and the sealing of the connecting screw rod after traction is completed; since the installation of the base body and the sealing do not need to be performed again, operation steps are simplified, the clinical operation difficulty is reduced, and the problem of slippage of an upper bone section to the original position is avoided.
