Method for manufacturing personalized ceramic bracket appliance

Abstract

The invention discloses a method for manufacturing a personalized ceramic bracket appliance, which comprises the following steps: scanning to obtain the appearance data of the tooth surface of a patient; using a three-dimensional auxiliary design software to obtain a bracket appliance bottom plate attached to the tooth surface to be bonded and a body digital model designed according to the orthodontic treatment requirement; additionally arranging a casting channel after being integrated into a complete bracket appliance model; obtaining a bracket appliance resin wax pattern by using a 3D printing technology; using a casting ceramic material which is consistent with or close to the tooth color of the patient as a raw material; preparing a bracket appliance blank by using an embedding hot die casting technology and deembedding; obtaining the bracket appliance to be bonded after polishing and glazing. The ceramic bracket appliance has the advantages that the manufacturing period is greatly shortened, the tooth surface appearance and the tooth color of different patients can be different, the bracket appliance bottom plate which is perfectly attached to the tooth surface to be bonded and the semitransparent bracket appliance whole body which is consistent with or close to the tooth color of the tooth surface to be bonded are manufactured, the accuracy of bonding positioning is improved through indirect bonding, the personalized reticulated bottom plate also improves the bonding strength of the bracket, so that the effect of invisible orthodontic treatment is achieved, and the personalized customization requirement in clinical treatment is more met.

Description

technical field [0001] The invention belongs to the field of orthodontics, and relates to a manufacturing method of a labial ceramic orthodontic bracket appliance. The bracket appliance has a rough bottom plate that fits the labial side of the teeth, and a translucent bracket appliance main body that is close to or consistent in color with the tooth surface to be bonded. Background technique [0002] With the gradual improvement of living standards, people's yearning for a better life has become stronger, and more and more people choose orthodontics to improve their quality of life. Orthodontics is a routine clinical method for treating human oral malocclusion. The fixed appliances used in orthodontics are composed of brackets, arch wires, and ligature rings (wires), among which bracket appliances mainly include metal and materials such as ceramics. In orthodontic treatment, bracket appliances mainly bond the base plate to the tooth surface, and fix the orthodontic archwir...

Problems solved by technology

[0004] The invention overcomes the problems that the bottom plate of the bracket appliance does not fit the patient's tooth surface in the manufacture of the traditional ceramic bracket appliance, and the color of the bracket appliance is quite different from that of the patient's teeth, and proposes a personalized labial ceramic bracket A manufacturing method of a slot appliance, the method obtains the topography data of the patient's tooth surface by means of scanning, and uses a three-dimensional auxiliary design software to obtain the bottom plate of the bracket appliance that fits the tooth surface to be bonded and the bracket designed according to the requirements of orthodontic treatment The digital model of the appliance body, and integrate the two parts into a complete bracket appliance model, using 3D printing technology to obtain the resin wax model of the bracket appliance, using glass ceramic materials that are consistent or close to the patient's tooth color as raw materials, through packaging The blank body of the bracket appliance was made by buried hot die-casting technology, and finally the bracket appliance to be bonded was obtained by polishing and glazing
