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 invention provides a three-dimensional force measurement method for a non-marking appliance. The non-marking appliance is made of an original integral dental plaster model using vacuum forming technology. The original integral dental plaster model is cut with a diamond grinding disc, and a single tooth to be corrected is removed from Separate the original integral dental jaw plaster model, and keep the relative positional relationship between the single tooth to be corrected and the original integral dental plaster model unchanged. Wear the non-marking appliance correctly on the cut overall dental plaster model, use a thermostat to simulate the real oral environment, and control the movement and rotation of the single tooth to be corrected through the X, Y, R axis displacement fine-tuning platform to simulate the orthodontics During the orthodontic correction process, the six-dimensional force sensor is used to measure the deformation restoring force applied to the t...

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 measurement field of the orthodontic force of non-marking and non-marking orthodontics in stomatology, in particular to the measuring system and method of the three-dimensional orthodontic force of the non-marking appliance. It measures and analyzes the value of teeth in the three-dimensional coordinate during the non-marking orthodontics. Stress situation. Background technique [0002] The so-called bracketless invisible orthodontic technology is relative to the traditional fixed orthodontic technology. The orthosis is made of medical resin film, and there is no orthodontic device for fixing the orthosis such as band rings, brackets, and arch wires. It is a "no brackets" invisible appliance. The generation and development of bracketless invisible orthodontics technology integrates modern orthodontics, digital image acquisition and processing technology, rapid prototyping technology and other scientific and technological achiev...
