Embodiment 1

[0046] This embodiment discloses the investigation of the sintering conditions of the aluminosilicate of the present invention, specifically:

[0047] Step 1. Use CAD / CAM technology to cut VITA In-Ceram 2000YZ porcelain blocks into ceramic pieces with a thickness of 1mm, a length of 21mm, and a width of 10mm. After sandblasting, they are cleaned with plasma water for 5 minutes, and placed in a VITA Zyrcomat porcelain furnace at 1000°C Roast for 15 minutes, take it out from the porcelain furnace and let it stand for 5 minutes to obtain zirconia porcelain pieces, which are set aside;

[0048]Step 2. Apply a thin (<0.5mm) layer of VITA VM9 adhesive effect porcelain powder mixed with VITA VM9 adhesive effect porcelain special liquid on the surface of the zirconia ceramic sheet treated in step 1, and then apply ceramic The firing bracket is placed in a ceramic furnace, and the temperature in the furnace is pre-fired to 500°C, and then kept for 6 minutes, then the temperature is rai...

Embodiment 2

[0053] This embodiment provides the preparation method of the aluminosilicate-assisted deposition of the silver-containing coating of the planting abutment ceramic material of the present invention, specifically:

[0054] Step 1. Use CAD / CAM technology to cut VITA In-Ceram 2000YZ porcelain blocks into ceramic pieces with a thickness of 1mm, a length of 21mm, and a width of 10mm. After sandblasting, they are cleaned with plasma water for 5 minutes, and placed in a VITA Zyrcomat porcelain furnace at 1000°C Roast for 15 minutes, take it out from the porcelain furnace and let it stand for 5 minutes to obtain zirconia porcelain pieces, which are set aside;

[0055] Step 2. Apply a thin (<0.5mm) layer of VITA VM9 adhesive effect porcelain powder mixed with VITA VM9 adhesive effect porcelain special liquid on the surface of the zirconia ceramic sheet treated in step 1, and then apply ceramic The firing bracket is placed in a ceramic furnace, and the temperature in the furnace is pre-...

Embodiment 3

[0060] Compared with Example 2 in this example, in step 2, the porcelain furnace is heated to 980°C and kept for 1 minute, and then kept under vacuum for 6 minutes to obtain a sintered aluminosilicate-coated tile; the rest of the conditions are same. For sample 1.

[0061] The implant abutment ceramic material impregnated with 1mol / l silver nitrate is marked as sample 1-1, and the implant abutment ceramic material impregnated with 5mol / l silver nitrate is marked as sample 1-5.

[0062] Compare the appearance of samples 1-1, 2-1, 1-5, and 2-5, and the results are attached image 3 shown. Among them, sample 1-0 represents the part of sample 1 that is not impregnated with silver nitrate, and 2-0 represents the part of sample 2 that is not impregnated with silver nitrate. After the sample was cut and dipped in silver nitrate solution, there was no special color display before the second sintering; after the sample was dipped and second sintered, it showed the color of reduced A...

Abstract

The invention discloses an aluminosilicate-assisted deposition of a silver-containing coating ceramic material and a manufacturing method for a planting abutment, which solves the problem that there is no antibacterial treatment of the ceramic abutment in the prior art. The preparation method of the present invention comprises the following steps: after coating a layer of aluminosilicate on the surface of zirconia tiles, firing to obtain sintered aluminosilicate coated tiles; immersion in an ultrasonic water bath; after the immersion, take out the aluminosilicate-coated tiles and bake them to reduce the silver nitrate impregnated on the coating of the aluminosilicate-coated tiles in situ to obtain aluminosilicate-assisted deposition Implant abutment ceramic material with silver coating. The invention has scientific design, simple operation, aesthetics and antibacterial properties, can continuously and stably exert antibacterial effect for a long time, and has simple preparation method, low cost and high safety.

Description

technical field [0001] The invention belongs to the technical field of oral cavity materials, and in particular relates to an implant abutment ceramic material and a preparation method for aluminosilicate-assisted deposition of a silver-containing coating. Background technique [0002] Oral implants have become a routine treatment for patients with clinical tooth loss. Despite the high success rate of oral implants, 5-11% of implants need to be removed due to implant failure. Implant failures generally fall into two broad categories: biomechanical and biological causes. Planting failure due to biological reasons is closely related to microbial plaque accumulation and bacterial infection. [0003] The abutment and the implant are important components of the implant system, the former extending from the implant part fixed in the bone, passing through the gum tissue, providing support for the superimposed structure of the implant (such as crown, bridge, denture, etc.). Abutm...
