Problems solved by technology

[0004] The present invention solves the problem of the low spatial resolution of CT cranio-maxillofacial bone data in the prior art, and the cranio-maxillofacial bone model made based on it cannot describe the anatomical details of the oral cavity and the dental model can only obtain part of the upper and lower jaw data and tooth data , the technical problem of being unable to obtain the adjacent relationship between the upper and lower jaws and the craniomaxillofacial bone, providing a manufacturing method that can produce a fine and personalized skull model that can describe the occlusal relationship of the teeth, which can help doctors intuitively understand the patient's oral cavity anatomical details

Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] See figure 1 , has described the simplified flow chart of the inventive method, comprises five basic steps:

[0032]The first step is to use CT tomography to obtain the tomographic image data of the patient's cranio-maxillofacial bone; the second step is to reconstruct the cranio-maxillofacial bone computer; the third step is to take plaster impressions of teeth and the three-dimensional data collection of plaster casts; the fourth step 1. Carry out data fusion and separation of the three-dimensional data of the tooth part obtained in the third step and the three-dimensional graphic data reconstructed from the CT image in the second step; the fifth step, respectively rapid prototyping and processing of the mandible data and the skull data from which the mandible has been stripped into Authentic models, and make organic connections.

[0033] Among the...

Abstract

The invention discloses a preparing method of fine personalized skull model to depict teeth occlusal relationship, which comprises the following steps: adopting CT tomographic scanning to pick patient skull tomographic image data, reconstructing three-dimensional skull facial bone computer, gathering three-dimensional data of teeth gupse pattern and gupse mode, fusing and separating data of three-dimensional image data, moulding skull data rapidly, connecting organically.

Description

Technical field: [0001] The invention relates to a method for manufacturing a skull model, in particular to a method for manufacturing a fine and individualized skull model that can describe the occlusal relationship of teeth. Background technique: [0002] Personalized head models play a very important role in preoperative program design, intraoperative program guidance, and skill training in craniomaxillofacial plastic surgery, stomatology, and other related disciplines. However, at present, personalized head casts are usually completed by rapid prototyping of CT data, because the spatial resolution of CT data is at the millimeter level, so fine anatomical relationships such as tooth occlusal relationships cannot be reflected, which greatly limits the use of head casts in dentistry. Applications. In dentistry, fine models of teeth are usually obtained by plaster impressions, but this method can only obtain part of the upper and lower jaw data and tooth data, and users can...
