Problems solved by technology

Although this method can analyze the pressure distribution of each point, once the pressure-sensitive paper is taken out, it is difficult to determine the corresponding position of each color point on the tooth, and this method is more suitable for qualitative analysis rather than quantitative analysis. force

Embodiment Construction

[0028] The present invention provides a three-dimensional force measurement method for a seamless appliance, which uses vacuum forming technology to make the original integrated dental and jaw gypsum model of the seamless appliance, cuts the original integrated dental and jaw plaster model with a diamond disc, and separates a single tooth to be corrected from The original overall dental and jaw plaster model is separated, and the relative positional relationship between the single tooth to be treated and the original overall dental and jaw plaster model remains unchanged. Correctly wear the non-marking appliance on the cut overall dental and jaw plaster model, use a constant temperature box to simulate the real oral environment, and control the movement and rotation of a single tooth to be corrected through the X, Y, and R axis displacement fine-tuning platform to simulate orthodontics. During the orthodontic treatment process, the six-dimensional force sensor is used to measur...

Abstract

The invention relates to a measure problem of dentistry no-orthodontic bracket no-trace rectification force in three dimensional coordinate, and provides a three-dimensional force measure system of non-trace rectification device as well as a measure method. The measure system and the measure method are characterized in that a single tooth to be straightened is separated from an integral jaw gypsum model, a six-dimensional force transducer is fixedly connected to the single tooth to be straightened, X, Y and R shafts displacement can be used for finely tuning a platform to simulate a straightening process, so that the position change of the single tooth to be straightened can be controlled, deformation of the non-trace rectification device is generated, deformation restoring force is generated, so that orthodontic force of non-trace rectification on the three dimensional coordinate can be determined. By researching the active force system and effect of the non-trace rectification device on the three dimensional coordinate, the orthodontic doctors can make a more reasonable and effective treatment scheme, and design staff can design a better customized non-trace rectification device. The method has the advantages of high measure precision, good real-time capability, simple and easy measure process.

Description

technical field [0001] The invention relates to the field of measurement of the traceless orthodontic force in three-dimensional coordinates in stomatology, especially the three-dimensional orthodontic force measurement system and method for the traceless appliance, which measures and analyzes the three-dimensional coordinates in the process of toothless orthodontics. Stress situation. Background technique [0002] The so-called invisible orthodontic technology without brackets is compared with traditional fixed orthodontic technology. It is a "no bracket" clear aligner. The emergence and development of bracketless invisible orthodontic technology has integrated modern orthodontics, digital image acquisition and processing technology, rapid prototyping technology and other multi-disciplinary and multi-field scientific and technological achievements. [0003] During tooth eruption and movement, the alveolar bone on the compression side resorbs, while the alveolar bone on th...
