Description

Oral cavity kind implant registration fixing device

Technical Field

The invention relates to the technical field of oral medical instruments, in particular to a registration fixing device for an oral implant.

Background

The implant is comfortable, beautiful and durable, does not damage adjacent teeth, and is a preferred restoration scheme after the existing teeth are lost; the existing dental implant generally means that an implant is implanted into an alveolar bone in a tooth lacking area until the implant is combined, and then a base station, an impression preparation and a false tooth wearing are sequentially implanted.

In order to make an implant denture according to the tooth shape of a user, the dental impression apparatus is required to reproduce the tooth row shape of the user, and the currently known impression apparatus is tray-shaped. After filling such a tray with impression material of moderate consistency, the tray with the impression is inserted into the mouth of the user and pressed into the desired dentition along the long axis of the teeth until the impression material sets and hardens, and finally the tray with set impression material is removed from the user's mouth and the impression is taken to complete the plaster cast of the user. The processes of obtaining, blending and cleaning the impression material adopted by the existing tray type impression making device are troublesome; doctors usually need to put trays of different specifications into the oral cavity of users according to experience to find the tray which is most matched with the actual dental arch size of the users; when the impression is taken, the impression material is in the mouth, which is easy to cause uncomfortable feelings such as choking, vomiting and breathing obstruction caused by sensitive throat.

The false tooth is worn by fixing the abutment to the implant by using a screw, then adhering and fixing the dental crown to the abutment by using an adhering material, and the dental crown is directly fixed to the abutment by using a repairing screw, but the dental crown is required to be accurately fixed, so that the correct installation angle of the dental crown is ensured, and the dental crown is required to be installed by a doctor according to visual inspection at present, and the installation angle of the dental crown cannot be accurately controlled.
