Problems solved by technology

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art, and propose a three-dimensional printing preparation method for the crown of the upper part of the dental implant to overcome the defects of cumbersome traditional techniques, long molding time, time-consuming and labor-intensive work, and low work efficiency. Due to the accumulation of errors caused by multiple processes, which affects the final precision, it solves the problem that the traditional casting molding has a thick oxide film that affects the fit with the oral cavity, and avoids the waste of raw materials caused by defective molding.

Embodiment 1

[0023] The three-dimensional printing preparation method for the crown of the upper part of the implant involved in this embodiment, the specific process includes dental model scanning, scanning data processing, crown restoration design, printing powder configuration, typesetting data transmission, and crown restoration printing Six steps:

[0024] (1) Dental mold shape scanning: use the existing technology to manufacture the plaster dental mold of the patient, computer-controlled optical scanner to scan the shape and size of the plaster model, collect the three-dimensional data of the optical impression of the plaster dental mold, and store the scanned data in the computer;

[0025] (2) Scanning data processing: using a computer system to process the three-dimensional data of the impression collected in step (1) and stored in the computer;

[0026] (3) Design of dental crown restorations: Design metal dental crowns by using the existing art implant software CAD installed in t...

Embodiment 2

[0034]The three-dimensional printing preparation method of the crown of the upper part of the implant involved in this example, its specific process is the same as the five steps in Example 1, and the components and proportions of the printing powder involved are as follows: albite, potassium feldspar, quartz, Talc powder, borax, sodium carbonate, potassium carbonate, sodium borate and cerium oxide, the printing powder is nano-scale fine particles, and the components of the porcelain tooth printing powder of selected color numbers are prepared and printed according to the following mass ratio: 25: 25:23:17:1:2:2:4.8:0.2, this ratio of printing powder is especially suitable for preparing posterior tooth crowns. The obtained posterior tooth crowns have a bending strength of 85MPa, a compressive strength of 800MPa, and a shrinkage rate of 0.5%, with high wear and corrosion resistance, beautiful appearance.

Embodiment 3

[0036] The three-dimensional printing preparation method of the crown of the upper part of the implant involved in this example, its specific process is the same as the five steps in Example 1, and the components and proportions of the printing powder involved are as follows: albite, potassium feldspar, quartz, Talc powder, borax, sodium carbonate, potassium carbonate, sodium borate, and cerium oxide, the printing powder is nano-scale fine particles, and the components of the porcelain tooth printing powder of selected color numbers are prepared according to the following mass ratios and printed: 26: 26:21:17:1:2:2:4.2:0.8, this ratio of printing powder is especially suitable for preparing incisor crowns. The prepared incisor crowns have a bending strength of 76MPa, a compressive strength of 720MPa, and a shrinkage 0.7%, with high wear resistance and corrosion resistance, beautiful appearance, bright color, milky white color.

Abstract

The invention belongs to the technical field of denture processing, and relates to a three-dimensional printing preparation method for the upper dental crown of a dental implant. The method specifically comprises the six steps of dental model scanning, scanning data processing, dental crown restoration design, printing powder preparation, typesetting data transmission and dental crown restorationprinting, wherein printing powder is prepared from albite, potassium feldspar, quartz, talcum powder, borax, sodium carbonate, potassium carbonate, sodium borate and cerium dioxide, wherein the printing powder is nano-scale fine particles. The three-dimensional printing preparation method for the upper dental crown of the dental implant has the advantages that the printing powder is prepared to control the color and transparency of a restoration, a computer controls a three-dimensional printer for molding through one-time printing, cumbersome procedures of traditional processing are eliminated, the work efficiency is high, the repair accuracy is high, a molded product has good compatibility with the oral cavity, the defect rate is low, and defective products are prevented from causing waste of raw materials; the production method is scientific in principle, easy to implement, safe and reliable, and the method is friendly to the application environment.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of denture processing, and relates to a three-dimensional printing preparation method for an implant upper crown, in particular to an integrated manufacturing method using computer-aided three-dimensional shape scanning, computer-aided design and computer three-dimensional printing. [0003] Background technique: [0004] In the field of dentistry, the manufacture of dental implants needs to first make a mold of the patient's teeth. The traditional production method is to take a mold from the patient's teeth, use the tooth prototype to make a silicone rubber impression, and use the silicone rubber impression to make a plaster model. A plaster cast is made into the desired implant. The traditional method of making implant crowns is to make resin crowns on the foundation piles of plaster molds based on the size and shape of the crowns, the occlusal relationship between the upper and lower jaws of the mi...
