Dental implant impression kit and dental implant impression manufacturing method

The invention relates to a dental implant stamping kit and a dental implant printing method, in particular to a dental implant printing kit and a dental implant printing method which use a connecting member and a positioning cap to position the implant body.

In general, in order to install a crown on the missing gum, the implant will be implanted first, and after the bone integration is completed, the implant and the gum can be overturned to create an anastomotic conformation to the implant and The crown of the gums.

Referring to the first figure, the first figure shows a schematic diagram of the prior art using an open mold to model the implant. As shown in the figure, the prior art mainly provides a table tooth PA1 on an implant PA201 implanted on the gingival PA200, and then fixes the abutment tooth PA1 to the implant PA201 by using a locking component PA2. At the same time, an open mold PA400 covers the gap around the implant PA201, and the locking component PA2 is exposed from the opening of the open mold PA400, and finally the impression material PA300 is filled into the open mold PA400 and the gum PA200. In the space formed by the enclosure, the shape of the surface of the abutment tooth PA1, the implant PA201 and the gum PA200 is reproduced. Among them, the operation mode of fixing the abutment teeth PA1 through the opening of the open mold plate PA400 is accurate, strong and stable, and the like. Advantages, but since the patient's mouth opening is limited when the abutment teeth, implants and gums are actually reproduced, it is difficult to lock and disassemble the abutment teeth PA1 in a limited space, which is very difficult to operate. .

As described above, in order to improve the shortcomings of the open mold, the prior art has developed a technique for performing implant and gum reprinting using a closed mold. Please refer to the second to fifth figures. The second figure shows a schematic diagram of the prior art using a closed mold to take a pattern of the implant, the abutment and the gum.
