Description

Technical Field

[0001] The utility model relates to the technical field of nail removal equipment for dental implants, in particular to a nail removal device for dental implants. Background Art

[0002] In the cavity department, dental implant is one of the common tasks. However, during the dental implant process, the implant nails need to be implanted in the gums to provide convenience for the later dental implantation. However, during the implant nail implantation process, various reasons such as surgical complications, incorrect implantation position, infection or patient needs may lead to implantation failure. The implant nails need to be removed from the patient's mouth. When removing the nails, there is a relative difficulty because there is no bridge to transmit torque. If they are pulled out hard, the gums will be damaged, so a nail remover is needed to complete the removal work. However, the nail removal end of the existing nail remover is usually a flat structure or only one side is opened to facilitate the entry of the implant nail. This structure is difficult to achieve the wrapping and limiting of the implant nail. When pulling out the nail, one end of the nail remover is easily separated from the implant nail, which is easy to cause damage to the patient's oral cavity. In addition, the existing nail remover is difficult to meet the limiting fixation of implant nails of different sizes when in use. When removing the nails, the impact force of the nail remover is difficult to adjust, which is easy to cause damage to the gums, which is inconvenient when used. Utility Model Content
