Description
Technical Field
The utility model relates to the technical field of dental medical instruments, in particular to a novel impression material injection device.
Background
The impression is used for making veneering, inlay, crown bridge, artificial tooth or implant repairing, and its purpose is to duplicate anatomical structure and provide morphological foundation for making repairing body. The method focuses on pushing the more dilute intra-orally injected alginate with the more dense alginate in the tray, which allows a smooth pressure-free impression.
The close degree of the edge of the prosthesis is important to the long-term curative effect of the prosthesis. For the restoration of the ceramic crown of the front tooth, in order to meet the requirement of beauty, the neck margin is designed to be the lower gingival edge, the front crown is folded to the subgingival part, the dental crown is split to the subgingival part, the lower gingival edge is deeper, and the teeth which need full crown restoration are required, the corresponding difficulty is increased when the impression is taken, the integrity of the impression of the neck margin directly influences the fitting degree of the restoration body, and the success or failure of the restoration treatment is determined. The integrity of the neck-edge impression is closely related to various factors such as impression technology, impression materials and the like, a small amount of alginate impression materials are taken by fingers and coated around a prepared tooth body to take a mould at the present stage, and the percent of pass of the alginate impression materials directly coated around the tooth is reported to be 40 percent and the percent of pass of the alginate impression materials injected by a disposable syringe to the periphery of the tooth is 80 percent. After preparing the abutment, a suitable tray is selected, alginate impression materials are mixed, part of the mixed impression materials are placed in a syringe, injection is carried out along the gingival margin, the abutment is completely covered, then the tray containing the impression materials is placed in the mouth, and the whole oral cavity impression is prepared. The advantage of using the injector to make the impression is that the injection head can enter the adjacent surface and gingival sulcus, and the pressure is large during injection, so that bubbles are not easy to generate.
However, the disadvantage of using a common disposable syringe clinically is that when a pressure-free primary impression is prepared by a two-component alginate primary film method, the syringe is straight and conical and too short in length, and is difficult to use in the mouth. When a neck edge impression is made, a straight conical needle is difficult to make a posterior tooth preparation, resistance is too large in the processes of piston placement and injection, and the impression is difficult to be quickly made in alginate impression operation time, so that the impression is solidified, and the impression taking failure is caused, and therefore a novel impression material injection device is urgently needed to be designed.
