Problems solved by technology

[0004] (1) The process is complicated, and the cost of time and materials is high;
[0005] (2) The error exists in each operation link. If there are many operation links, the final cumulative error will be large, and the gingival shape cannot be copied very accurately.
[0006] (3) When there are more than two implants or bridges, it is difficult to place the personalized impression post in place, and it needs to be placed in sections, which makes the operation more complicated and more difficult to make an accurate impression

Embodiment 1

[0040] Such as figure 1 As shown, the patient has lost three front teeth and needs to implant the front teeth aesthetic area. The impression method for accurately replicating the shape of the gums in this embodiment includes the following steps:

[0041] Step (1), the gums are shaped to obtain a shaped temporary denture 5; the shaped temporary denture 5 is put into the vacant part 3 of the gum 4, and cooperates with the surrounding upper teeth 1 and lower teeth 2, as figure 2 shown.

[0042] Step (2), while wearing the formed temporary denture 5 of step (1), use a second silicone impression to make sure that the crown of the temporary denture 5 is fully in place in the oral cavity, and the crown is tightly combined with the implant. gaps, such as image 3 as shown, image 3 Both silica gel 6 and mold 7 are prior art.

[0043] Step (3), taking the model to obtain a precise and bubble-free silicone model that is stable in shape with the patient's teeth, such as Figure 4 A...

Embodiment 2

[0052] The impression method for accurately replicating the shape of the gingiva in this embodiment, in view of the situation where the crown of the temporary denture is short and poorly retained, the temporary crown can be appropriately lengthened, and then the silicone model can be taken, so that the temporary crown can perfectly replace the impression column, specifically including the following steps:

[0053] Step (1), the gums are shaped to obtain a shaped temporary denture with an elongated crown; the shaped temporary denture is put into the vacant part 3 of the gum 4 to cooperate with the surrounding upper teeth 1 and lower teeth 2 .

[0054] Step (2), while wearing the formed temporary denture 5 of step (1), use a second silicone impression to make sure that the crown of the temporary denture 5 is fully in place in the oral cavity, and the crown is tightly combined with the implant. Gap, silica gel 6 and mold 7 are all prior art.

[0055] Step (3), taking the model t...

Abstract

The invention relates to an impression method for accurately copying a gingival pattern. The method belongs of the field of oral implant restoration, and comprises the steps of directly using a formedtemporary denture as an impression column, directly manufacturing an artificial gingiva on the impression column, and after finishing model filling, taking down a temporary crown, disinfecting and wearing into a patient mouth. The method provided by the invention is simple without complicated and overloaded processes, the errors caused by repetitively copying the model for multiple times are avoided, the gingival pattern is accurately transferred, the problems of complicated and overloaded processes of an individualized impression column technology, easiness in producing error, and difficultyin operating multiple teeth are effectively solved, the processes are simple, and the errors are small; the problems that a common path of insertion cannot be obtained when the model is taken througha traditional mode, multiple division is required, and combined wear is complicated to operate and big in difficulty are avoided; under the conditions of saving time and a lot of material cost, an accurate impression effect can be obtained, and the method is simple to operate and easy to popularize.

Description

technical field [0001] The invention relates to an impression method, in particular to an impression method for accurately replicating the shape of gums, and belongs to the field of oral implant restoration. Background technique [0002] Implant restoration has become the main restoration method for missing teeth. Due to the texture of the gum itself, it is easy to deform and collapse without temporary denture support. Mastering the gingival shape and contact point design of implant dentures will not achieve good aesthetic and physiological effects. [0003] The current method of personalized impression post for gingival morphology replication is as follows: cast gypsum model—silicone rubber copy temporary crown piercing gingiva partial negative model—resin (or other material) stacking personalized impression post—intraoral impression taking —Go to the workshop to reproduce the final model. However, this method has the following problems: [0004] (1) The process is compl...
