Problems solved by technology

But for lab animals, it's much more difficult
The existing orthodontic devices are designed with brackets bonded to the teeth, and some with bands bonded to the teeth. However, due to the relatively poor compliance of animals, these orthodontic devices often fall off, which affects the smooth progress of the experiment.
In addition, the movement of teeth is a three-dimensional movement, including buccolingual, mesio-distal, and gingival. Existing orthodontic devices can only control the movement of teeth in the near-distal direction, but cannot realize the three-dimensional direction of the teeth. sports

Embodiment Construction

[0018] In order to clearly illustrate the technical features of the solution, the solution will be described below through a best specific implementation mode. The purpose of the present invention is to establish a canine animal experimental method for orthodontic tooth movement, and the implementation steps of the method are as follows:

[0019] (1) Preparation of experimental canine animals: fasting the day before the operation, Sumianxin 0.1ml / kg, intramuscular injection of ketamine 3mg / kg, reaching the depth of anesthesia for the operation ten minutes later;

[0020] (2) Preparation of canine dentition plaster model: use impression paste to make individual trays, repair the individual trays, use alginate impression material to make canine dentition impressions, and superhard plaster infusion to obtain canine dentition models;

[0021] (3) Making casting metal crowns for anchorage teeth and moving teeth: making a movable model, then making a wax model on the movable model, ...

Abstract

The invention relates to a dog animal experimental method for orthodontic tooth movement, which belongs to the field of experimental zoology, The animals of the experimental method meet the characteristics of human oral cavity; because a cast metal crown is adopted, an orthodontic device can be well fixed in the oral cavity; in addition, a 'square hole buccal tube'-shaped lug is completely cast on the tongue side of the cast metal crown as a track structure for tooth movement, and a 0.019*0.025-inch stainless steel square wire is matched to manufacture a guiding device for tooth movement, so as to control the tooth movement in three-dimensional directions. The dog animal experimental method for orthodontic tooth movement can reduce the fall-off rate of the orthodontic device in an orthodontic tooth movement process and realize the tooth movement in the three-dimensional directions, so as to guarantee smooth dog animal experiments.

Description

technical field [0001] The invention relates to a canine animal experiment method for orthodontic tooth movement, belonging to the field of experimental zoology. Background technique [0002] With the improvement of living standards, more and more people choose orthodontic technology to correct deformities such as misaligned teeth and protrusion. The core of orthodontics lies in the controllable movement of teeth in the jawbone. For this reason, many scholars have done a lot of research on tooth movement. There are many factors that affect tooth movement, and some implementation measures cannot be directly studied on human body. Therefore, animal experiments have become one of the basic experimental methods for orthodontic tooth movement research. [0003] Reasonable selection of experimental animals plays a key role in the establishment of animal models of orthodontic tooth movement. Currently, commonly used animals are rats, miniature pigs, rabbits, dogs, and primate mon...
