Auxiliary device for in-vitro adhesion of dental crown and abutment of dental implant

Abstract

The invention discloses an auxiliary device for in-vitro adhesion of a dental crown and an abutment of a dental implant. The auxiliary device comprises a cylindrical permanent magnet, wherein a cylindrical lamination rod is coaxially fixed on the lower surface of the cylindrical permanent magnet; the diameter of the lamination rod is smaller than that of the cylindrical permanent magnet; a threadgroove at the middle position of the lower end of the lamination rod is in thread connection with a screw rod; the lower end of the screw rod is coaxially fixed with the upper end of a round rod; thediameter of the round rod is equal to the diameter of the lamination rod. The auxiliary device for the in-vitro adhesion of the dental crown and the abutment of the dental implant is convenient to mount and dismount; a doctor adheres the abutment and the dental crown through an adhesive; after the adhesion is finished, the doctor rotates the cylindrical permanent magnet and the lamination rod is separated from the round rod; the abutment and the dental crown are both bonded with a lamination assembly round tube through the adhesive, and the doctor presses an adsorption splicing sheet to allowthe adsorption splicing sheet release from the adhesive; the adsorption splicing sheet and the adhesive are convenient to release; the dental crown and the adhesive are not released and the working efficiency of the doctor is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an auxiliary device for bonding an implant crown and an abutment in vitro. Background technique [0002] For example, the patent of invention with application publication number 201720181026.X discloses an auxiliary device for in vitro bonding of implant crowns and abutments, including a base for receiving the abutment, the base includes an upper surface and a lower surface, and the upper surface of the base There is a pipe string vertically on the top, and a casing is sleeved on the outside of the pipe string. There is a clearance fit between the outer surface of the pipe string and the inner surface of the casing. There is clearance fit between the inner surfaces of the holes, and the end of the casing away from the base is a closed end. The through-piercing column and sleeve are used in the in vitro bonding process of the abutment and the crown, which perfectly replac...
