Tooth occlusion model manufacturing method, tooth occlusion model and orthodontic force measuring method

Abstract

The invention provides a tooth occlusion model manufacturing method, a tooth occlusion model and an orthodontic force measuring method, and relates to the field of tooth orthodontics. The tooth occlusion model manufacturing method comprises the following steps of preparing simulation teeth in the appearance of a standard tooth body; bonding a support groove on each simulation tooth; manufacturinga bottom supporter for the sequentially arranged simulation teeth; rebuilding a peridental membrane and inherent alveolar bone for each simulation tooth; sequentially arranging all simulation teeth byarch wires, and connecting and fixing the simulation teeth; then, putting the simulation teeth into the bottom supporter; casting casting materials of simulation cancellous bone into the bottom supporter for rebuilding the cancellous bone for each simulation tooth; and forming a tooth model after the casting material solidification. The tooth model is a standard model; the physiological structureof teeth in the human oral cavity can be precisely simulated; and the elasticity modulus and the biomechanical performance of the peridental membrane, the inherent alveolar bone and the cancellous bone of the human teeth can be simulated. The strain and the displacement of the teeth after orthodontic strength application can be precisely measured; and the practical received orthodontic force anddirection of the teeth are calculated according to the elasticity modulus of used materials.

Description

technical field [0001] The application relates to the field of orthodontic treatment, in particular, to a dental Model making method, teeth Model and measurement method of orthodontic force. Background technique [0002] The main purpose of orthodontic treatment is to solve the patient's fault Crooked, aligned 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 most concerned ab...

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
