Problems solved by technology

Three-dimensional measuring instrument measurement is more accurate than manual measurement. It reflects the characteristics of the model from a three-dimensional perspective. The calculation is simple and reduces the workload of the measurer. However, the measurement probe may not be able to reach the measurement blind area, resulting in measurement errors and the required equipment technology is more complex and expensive.
This method has statistical significance only in experiments with a large number of samples. If the samples are limited or there are large differences between individuals, the measured data cannot truly reflect the growth and development of the jaw

Embodiment Construction

[0039] The digital measurement method for the growth and development of the teeth and jaws of the present invention continuously tracks and regularly acquires the teeth and jaws models of the same group of children, from which the normal (occlusal) teeth and jaws models are screened out, and the midpoint of the central incisor papilla, The three-point relationship between the midpoint of the left first palatal fold and the midpoint of the right first palatal fold is registered to the dental model of the same individual at different growth and development stages, and the dental arch curve of the previous stage dental model is used as the reference to measure the jaw model of the next stage. Finally, statistical analysis was carried out to determine the normal growth and development of teeth and jaws in this area. What needs to be explained here is that the above-mentioned (occlusion) means a word, which is composed of "tooth" and "he", with "tooth" on the left and "he" on the ri...

Abstract

The invention relates to the technical field of computer-assisted orthodontic treatment, in particular to a method for digitally measuring dental jaw growth and development laws. The method includes continuously tracking and regularly acquiring dental jaw models of the same child group; screening normal (occlusion) dental jaw models from the dental jaw models; registering the dental jaw models of the same individual at different growth and development stages by the aid of positional relations of the middle point of the central incisor papilla in palatal rugae of the dental jaw of the individual, the middle point of left first palatal rugae of the dental jaw of the individual and the middle point of right first palatal rugae of the dental jaw of the individual; measuring variation data of jaw bones of the individual at a next stage on the basis of a dental arch curve of the dental jaw model of the individual at a previous stage; determining the normal dental jaw growth and development laws of certain areas by means of statistics and analysis. The method has the advantages that the measurement accuracy is high, measurement results are stable and reliable, and measurement procedures are simple and feasible.

Description

[0001] technical field [0002] The invention relates to the technical field of computer-aided orthodontic treatment, in particular to a digital measurement method for the growth and development law of teeth and jaws. Background technique [0003] The growth and development of the jaw is one of the important theoretical foundations of orthodontics. Dental models can objectively and completely record the shape and size of teeth, alveolar bone, dental arch, etc., lesions, tooth arrangement, (occlusal) curve height, and the relationship between the upper and lower jaws, etc. important method of development. In addition, the morphological structure of teeth and jaws among people of different races, regions, and genders has its own characteristics and rules, and the related research is complex and diverse. With the advancement of science and technology, the exploration and research on the growth and development of teeth and jaws has changed from cross-sectional observation to l...
