Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dental implant instruments, in particular to dental implant auxiliary forceps. Background Art
[0002] Implant dentures, also known as dental implants, have become one of the conventional treatments for repairing missing or damaged teeth. Clinically, it is required that the implant and bone tissue can achieve good bone integration. Titanium and titanium alloys are the most widely used dental implant materials due to their good biocompatibility and ideal mechanical properties. Repairing missing or damaged teeth through implant technology can achieve a harmonious and natural aesthetic effect between the patient's oral and facial appearance, and also help improve the chewing function. The effect can generally last for more than 10 years. Currently, dental implants, that is, fixed dentures implanted into the bone, are an advanced method for repairing autologous tooth loss in oral medicine. The so-called dental implant technology is to drill implant holes on the patient's gums with a drill after the patient's teeth are missing, and then fix the artificial teeth in the implant holes. Auxiliary devices are needed to assist in implantation.
[0003] A Chinese patent discloses an auxiliary device for dental implant installation, with the publication number CN213665874U. The technical solution disclosed in the patent document is as follows: it includes a first rod body, one end of the first rod body is fixedly connected to a first clamping plate, one side of the first rod body is fixedly connected to a first connecting rod, one end of the first connecting rod is movably connected to a second connecting rod through a pin shaft, one end of the second connecting rod is fixedly connected to a second rod body, one end of the second rod body is fixedly connected to a second clamping plate, and one side of the first rod body and the second rod body are both fixedly connected to anti-slip pads.
[0004] In order to solve the problem that the dental implant is not firmly clamped and is easy to fall, the existing technology adopts the method of setting an anti-skid pad to deal with it. However, the clamping stability is poor. This structure drives the first clamping plate and the second clamping plate to clamp the dental implant through the elastic force of the spring. When clamping, the first clamping plate and the second clamping plate are both inclined relative to the dental implant, which makes the contact area between the anti-skid pad and the dental implant smaller, which leads to the problem that the clamping stability is poor and easily affects the smooth progress of the dental implant.
