Embodiment Construction

[0015] The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.

[0016] The method for virtual reconstruction of the functional aesthetic form of tooth dentition of the present invention has the following steps:

[0017] 1) Batch 3D scanning of normal upper and lower jaw dentition as standard template data;

[0018] 2) The current dentition that needs to be virtually reconstructed in the 3D scan is recorded as data D1;

[0019] 3) Select a set of standard template data from step 1) and record it as data D2;

[0020] 4) Taking the unchanged part after reconstruction as the common area, using the common area registration algorithm to register data D2 with data D1;

[0021] 5) If you need to retain the original tooth shape, extract the three-dimensional data of the crown of each tooth in data D1 and register it on the corresponding tooth in data D2 to obtain virtual prediction data;

[0022] 6) If you don't need to keep the or...

Abstract

A method for highly efficient virtual reconstruction of tooth dentition functional aesthetics form includes such steps as 1) scanning normal maxillary and mandibular dentition as standard template data; 2) scanning the current dentition requiring virtual reconstruction, recording the current dentition as data D1; 3) selecting a set of standard template data from that step 1) and recording the dataas data D2; 4) registering the data D2 with the data D1 by taking the unchanged part after reconstruction as a common area; 5) if that original tooth shape is to be preserved, extracting the three-dimensional data of the crown of each tooth in the data D1, registering the three-dimensional data on the corresponding tooth of the data D2, and obtaining the virtual prediction data; 6) if that original tooth shape does not need to be retained, the data D1 is directly replaced with the data D2 to obtain the virtual prediction data; 7) the virtual prediction data is three-dimensionally printed to present the entity of the prediction result. The reconstruction result of the invention can be directly used for digitally restoring the dental functional aesthetics form of the teeth, and the functional aesthetics design level of the operator is rapidly improved.

Description

Technical field [0001] The invention relates to a method for virtual reconstruction of tooth dentition, in particular to a method for high-efficiency virtual reconstruction of tooth dentition functional aesthetic form. Background technique [0002] The normal tooth database currently only has a basic shape, which is mainly used as a basic template for manual interactive CAD design. However, for the aesthetic shape, because of the higher degree of personalization, there is no ready-made database, especially for the Chinese. The standard data of tooth dentition aesthetics not only requires a single tooth, but also the arrangement relationship between the teeth, that is, the dentition. Therefore, it is very difficult for operators to realize the functional aesthetic design of tooth dentition for tooth dentition restoration and orthodontic diagnosis and treatment; not only is the work flow long, but also often not satisfactory results are obtained. Summary of the invention [0003] T...
