Problems solved by technology

However, for edentulous patients, due to the large number of missing teeth, when taking impressions with silicone rubber, the silicone rubber has no adhesion to adjacent teeth and is easy to deform. The possibility of deformation makes the position of the transfer rod easy to shift; the final result is that the tooth plaster model made has a large error, which in turn affects the accuracy of the made restoration

Embodiment

[0043] A method for making a precise tooth transfer model of an edentulous jaw, comprising the following steps:

[0044] Step 1: Taking impressions for the first time, adopting the method of window-opening type impression-taking, specifically including, first fixing the transfer rod 3 on the implant with fixing screws, mixing the silicone rubber on the window-opening tray, and then placing the silicone rubber impression With the tray of wood in place in the mouth, make sure that the setscrew can pass through the fenestration. About 4-5 minutes after the impression material is solidified, loosen the fixing screw from the opening to completely dislocate the transfer rod 3, and then take the tray out of the oral cavity. At this time, the transfer rod 3 together with the fixing screw is taken out of the oral cavity together with the silicone rubber impression, and then the implant substitute 2 is installed in the silicone rubber impression, and the substitute 2 is fixed on the tra...

Abstract

The invention discloses a making method of an edentulous jaw precise tooth transfer model. The making method includes following steps: step 1, modeling for the first time: using a tray and silicone rubber, and adopting a windowing modeling method to acquire a patient tooth matching relationship; step 2, pouring a tooth gypsum model on a solidified silicone rubber impression, and obtaining a preliminary model; step 3, mounting transfer rods on the tooth gypsum model in situ; step 4, arranging a position fixing device between each two adjacent transfer rods; step 5, cutting one position fixing device to form an incision; step 6, trying the transfer rods connected with the position fixing devices on in the mouth of a patient according to an arranging sequence, and adjusting positions of the transfer rods; step 7, adopting a curing agent to reconnect the position fixing devices which are cut open at the incisions; step 8, adopting the windowing modeling method for second-time modeling; step 9, pouring a tooth gypsum model on a silicone rubber impression obtained by second-time modeling, and obtaining a final model. By the making method, making accuracy of tooth gypsum models for edentulous jaw patients can be improved effectively.

Description

technical field [0001] The invention relates to the technical field of denture production, in particular to a method for producing a precise tooth transfer model of an edentulous jaw. Background technique [0002] Dental implants are a common method of replacing missing teeth. [0003] At present, dental implant restoration methods mainly include several steps of implant placement, implant abutment installation in place, and restoration retention installation. In order to make a suitable restoration, tooth impression is very important. Denture manufacturers usually use the plaster model of the patient's teeth as the basis for the production and processing of the restoration. Therefore, an accurate dental plaster model can greatly reduce the chances of later restorations returning to the factory for rework. [0004] In the prior art, the fenestration-type impression-taking method is often used for the impression-taking of the edentulous jaw, that is, the fenestration-type t...
