Rat anterior tooth reverse jaw dental crown and manufacturing method thereof

Abstract

The invention relates to a rat anterior tooth reverse jaw dental crown that is characterized in that an upper jaw dental crown is a double-tooth single crown and a lower jaw dental crown is a single-tooth single crown. According to the invention, occlusion disorder is caused to rats from two aspects of the thickness and angle of the dental crown, and a clinically applied digital oral scanning technology and a 3D printing technology extend to the field of basic experiments, so that the universal dental crown is made; the maxillary double-tooth single crown is realized; the reverse jaw angle and height are repeated, the dental crown strength is high, the manufacturing and wearing are simple, and the repetition rate is high. Close contact without shedding is realized; the dental crown can be kept in mouth for more than two months; and the successful rate is high. And personal errors caused by operation differences of experimenters are greatly reduced. The dental crown can be directly applied to rats with similar weights at the same age group, the anesthesia frequency of experimental animals is reduced, the experimental animals only need to be anesthetized once when dental crowns are installed, operation steps are simplified, time for taking molds from mouths of the rats to manufacture the dental crowns is saved, and experimental operation difficulty is reduced.

Description

technical field [0001] The invention relates to the field of basic research of stomatology and jaw science, in particular to a rat anterior crossbite crown. Background technique [0002] In order to study the changes in the emotional and physical conditions of rats in the case of occlusal disorders, in order to find solutions to the bad emotions and other adverse responses, to make crowns or dentures that make rats occlusal disordered, single-tooth teeth are mostly used at present. Single crowns are used to make rat tooth crowns. Single-tooth single crowns have low strength and are easy to bite off or deform. In the production, the dental crown is made by taking an impression in the mouth of each rat, and the experimental animals need to be anesthetized many times, the operation steps are cumbersome, and the experimental operation is difficult. [0003] Rats have two incisors and six molars in each of the upper and lower jaws, a total of 16 teeth, and there is an edentulous...

[0002] In order to study the changes in the emotional and physical conditions of rats in the case of occlusal disorders, in order to find solutions to the bad emotions and other adverse responses, to make crowns or dentures that make rats occlusal disordered, single-tooth teeth are mostly used at present. The single crown is used to make rat tooth crowns. The strength of the single tooth single crown itself is low, and it is easy to bite off or deform.
