Dental model making method, dental model and orthodontic force measurement method

Abstract

The application provides a method for making a dental model, a dental model and a method for measuring orthodontic force, which relate to the field of orthodontics. The manufacturing method of the tooth and jaw model includes: preparing artificial teeth with a standard tooth shape, and bonding brackets on each artificial tooth; making a bottom bracket according to the artificial teeth arranged in order; rebuilding the periodontal ligament for each artificial tooth and the inherent alveolar bone; use the arch wire to arrange all the simulated teeth in order and connect and fix them into the base bracket, pour the pouring material simulating cancellous bone into the base bracket to reconstruct the cancellous bone for each simulated tooth, and wait for pouring After the material is solidified, the dental model is formed. The jaw model in this application is a standard model, which can accurately simulate the physiological structure of teeth in the human oral cavity, and simulate the elastic modulus and biomechanical properties of the periodontal ligament, intrinsic alveolar bone and cancellous bone of human teeth. The application can accurately measure the strain and displacement of the teeth after orthodontic force application, and calculate the magnitude and direction of the orthodontic force actually received by the teeth according to the elastic modulus of the material used.

Description

technical field [0001] The present application relates to the field of orthodontic treatment, in particular, to a method for making a dental model, a dental model and a method for measuring orthodontic force. Background technique [0002] The main purpose of orthodontic treatment is to solve the patient's malocclusion and align the teeth. In orthodontic treatment, the teeth gradually move to the target position under the action of orthodontic force. The orthodontic target not only includes the accurate movement of the teeth, but also hopes to minimize the root absorption and alveolar damage caused by excessive orthodontic force and reciprocating movement. Bone resorption and loosening of teeth. Therefore, the goal of orthodontic treatment is to move the teeth under the action of light force, while avoiding the reciprocating movement of the teeth, shorten the course of treatment, and promote dental health. Therefore, in the process of orthodontic treatment, clinicians are m...

Problems solved by technology

At present, the most accurate method is the contact measurement method. Due to the large size of the measurement tool, the bracket is in contact with the arch wire through the inner surface instead of the outer surface. The measurement device needs various degrees of freedom of adjustment and a firm fixed test device. , it is difficult to realize clinical real-time monitoring research

There are also scholars who place miniature sensors in orthodontic brackets to measure various pressures and stresses on the teeth. However, due to the need for lead wires and the high price of wireless devices, they cannot be implemented in clinical practice at present, and can only be used for enlarged models.

Even in the enlarged model, the system construction is still very difficult, and the measurement methods are cumbersome, expensive, and difficult to popularize and apply
