Problems solved by technology
[0002] At present, when there is no tooth in the mouth for immediate load arrangement of the upper part of the implant, the conventional method is to take the mold and then manually arrange the teeth on the model, which is time-consuming and laborious, and the accuracy is not high. After the try-in in the mouth, it is often necessary to rework and re-arrange the teeth
Moreover, Chinese teeth have their unique bony landmarks corresponding to the corresponding tooth positions. The maxillary first molar corresponds to the root of the maxillary zygomatic bone, and the maxillary first premolar corresponds to the canine socket. The known digital tooth arrangement method does not have According to the characteristics of Chinese teeth, it cannot meet the bone needs of Chinese teeth, and the applicability of tooth arrangement is not high

Embodiment Construction
[0028] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0029] Such as figure 1 , 2 , 3, 4 shows a kind of toothless implant immediate load personalized three-dimensional digital tooth arrangement method suitable for Chinese, including the following steps:
[0030] (1) Construction of 3D tooth model for edentulous implants: Continuous cone-beam CT scans were performed on the patient's mouth, and the scanning results were imported into Mimics 17.0 software to reconstruct a 3D dental model of edentulous implants;
[0031] (2) Optimization of the 3D tooth model for edentulous implants: perform multi-order curve interpolation and adaptive subdivision of the point cloud data of the 3D dental model for edentulous impla...

The invention discloses a toothless implantation immediate loading personalized three-dimensional digital tooth arrangement method suitable for Chinese people. The method comprises the steps of toothless implantation three-dimensional tooth model rebuilding, toothless implantation three-dimensional tooth model optimizing, digital tooth arrangement standard point determining, maxillary personalizeddigital tooth arrangement and mandibular personalized digital tooth arrangement. The toothless implantation immediate loading personalized three-dimensional digital tooth arrangement method suitablefor Chinese people is reasonable in structure, and has the advantages of being simple in structure, convenient to use, capable of saving time and labor, high in precision, high in pertinence and the like, and the problem that a tooth arrangement method for the characteristics of teeth of Chinese people does not exist is effectively solved.
Description
technical field [0001] The invention relates to the field of three-dimensional digital tooth arrangement methods, in particular to a personalized three-dimensional digital tooth arrangement method for immediate load of toothless implants suitable for Chinese people. Background technique [0002] At present, when the full mouth is edentulous for immediate load placement on the upper part of the implant, the routine is to take the mold and then manually arrange the teeth on the model, which is time-consuming and laborious, and the accuracy is not high. Moreover, Chinese teeth have their unique bony landmarks corresponding to the corresponding tooth positions. The maxillary first molar corresponds to the root of the maxillary zygomatic bone, and the maxillary first premolar corresponds to the canine socket. The known digital tooth arrangement method does not have According to the characteristics of Chinese teeth, it cannot meet the bone needs of Chinese teeth, and the applicabi...
