Embodiment 1

[0022] The three-dimensional printing preparation method of the implant bridge involved in this embodiment, its specific process includes tooth model shape scanning, scanning data processing, dental bridge restoration design, printing powder configuration, typesetting data transmission, dental bridge restoration printing, matching Interface processing seven steps:

[0023] (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;

[0024] (2) Scanning data processing: use the computer system to process the three-dimensional data of the impression collected in step (1) and store in the computer, and calculate the retainer and connection of the dental bridge according to the way in place and the way of tooth a...

Embodiment 2

[0034] The three-dimensional printing preparation method of the implant bridge involved in this example, its specific process is the same as the seven steps in Example 1, and the components of the printing powder involved are 64:25:5:5:1 by weight. Proportional printing powder is especially suitable for the preparation of incisor bridges. The prepared incisor bridges have a bending strength of 80MPa, a compressive strength of 900MPa, a shrinkage rate of 0.4%, and are highly wear-resistant and corrosion-resistant.

Embodiment 3

[0036]The three-dimensional printing preparation method of the implant bridge involved in this example, its specific process is the same as the seven steps in Example 1, and the components of the printing powder involved are 69:24:2:2:1 by weight. Proportional printing powder is especially suitable for preparing molar bridges. The prepared incisor bridges have a bending strength of 105MPa, a compressive strength of 1100MPa, a shrinkage rate of 0.2%, and are highly wear-resistant and corrosion-resistant.

Abstract

The invention belongs to the technical field of denture processing, and relates to a three-dimensional printing preparation method for the dental bridge of a dental implant. The method specifically comprises the seven steps of dental model scanning, scanning data processing, dental bridge restoration design, printing powder preparation, typesetting data transmission, dental bridge restoration printing and cooperative connector processing. The three-dimensional printing preparation method for the dental bridge of the dental implant has the advantages that a computer assists in design, and three-dimensional scanning is performed on the shape and size of a dental model, so that the production procedure is simplified, the design precision is high, the computer controls a three-dimensional printer to print for molding, cumbersome procedures of traditional processing are eliminated, the work efficiency is high, the repair accuracy is high, a molded product has good compatibility and biocompatibility with the oral cavity, the finished product ratio is high, and defective products are prevented from causing waste of raw materials; the precision of the cooperative connection of the dental bridge and a foundation pile is high, the installation is firm and reliable; 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 of an implant bridge, 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] Dental bridge restoration is a method of denture restoration technology. It mainly uses natural teeth or implants at both ends or one end of the missing tooth gap as abutment teeth, and makes denture retainers on the abutment teeth, and connects them with artificial teeth to form A whole, and then cement the denture crown to the bridge with cement. This restoration method can fill the missing tooth, prevent the adjacent teeth from shifting, avoid irregular teeth and malocclusion, and restore the chewing, pronunciation and appearance of the teeth. The traditional method of making dental b...
