Description

Oral cavity kind implant registration fixing device

Technical Field

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

Background

The implant is comfortable, beautiful and durable, does not damage adjacent teeth, and is the preferred restoration scheme after the loss of the teeth at present. The dental implant is a dental implant which anchors root-type pure titanium or titanium alloy material in jaw bone to provide support and fixation for repairing lost teeth, and in order to manufacture the dental implant according to the tooth shape of a user, the tooth row shape of the user needs to be copied through a dental impression device, and the currently known dental impression devices are all in a tray shape. After filling such a tray with a uniformly viscous impression material, the tray is inserted into the mouth of the user, the user bites down on the impression material until the impression material sets and hardens in the mouth, leaving an impression of the user's teeth on the impression material, and finally the tray with the set impression material is removed from the user's mouth and used as a mold to form a model of the user's dentition.

However, the above method has the following disadvantages: firstly, the process of obtaining, blending and cleaning impression materials adopted by the tray type dental impression device is troublesome; secondly, doctors usually need to put trays with different specifications into the oral cavity of users according to experience to find the impression tray which is most matched with the actual dental arch of the users; thirdly, when reusing the dental impression tray, it is necessary to remove the residual impression material in the tray and to clean and sterilize the empty tray; fourthly, when a user bites down the impression tray, the oral cavity is filled with the impression material, and strong discomfort is easily generated.

Therefore, we propose an oral implant registration fixture to solve the above problems.
