Abstract

The invention discloses a zirconium dioxide all-ceramic tooth through 3D printing. The zirconium dioxide all-ceramic tooth through 3D printing comprises a false tooth body and connection rods, and connection grooves with downward openings are formed in the false tooth body; the upper ends of the connection rods are connected with the false tooth body through the connection grooves, the lower endsof the connection rods extend into the root of an incomplete tooth and are connected with root tubes, and accordingly the false tooth body is fixed. According to the zirconium dioxide all-ceramic tooth through 3D printing, the false tooth body and the connection rods are prepared by zirconium dioxide composite powder through a 3D printing technology, the nanoscale zirconium dioxide powder is adopted as a main material, the tooth has good biocompatibility and is not easily dissolved and deformed in the oral cavity, and the service life of the false tooth body is prolonged; the tooth is preparedby adopting the 3D printing technology, the product precision is high, the production period can be shortened, and the workload can be reduced; the false tooth body can be disassembled from the connection rods, and the tooth is convenient to replace, easy to clean and repair and wide in suitable population range.

Description

technical field [0001] The invention relates to the technical field of dental medical equipment, in particular to a 3D printed zirconia all-ceramic tooth and a preparation method thereof. Background technique [0002] The root of the tooth is the part of the tooth buried in the gum, also known as the tooth root. Teeth are an important part of the oral cavity and are the masticatory organs of the human body. The incidence of dental disease is on the rise with age. However, suffering from "tooth decay" (caries) is not treated in time, and as a result most of the teeth are damaged, and some people easily pull out the remaining stump roots. For many years, people think that it is a matter of course to extract the residual tooth roots in the oral cavity and then install the teeth. In fact, it is not the case. Pulling out the residual tooth roots will easily cause facial muscles to collapse, causing uneven force on the roots of other teeth, and other teeth will slowly recover. ...
