Description
Technical Field
The invention relates to the field of oral medicine, in particular to a complete denture manufacturing method and device based on data mining.
Background
According to the third national epidemiological investigation of oral health, the number of patients with the Chinese edentulous jaw exceeds ten million. Although implant restoration is a more ideal restoration method for dentition loss, conventional complete dentures remain the treatment of choice for most edentulous patients due to problems of local anatomical conditions, general health and economic conditions. Meanwhile, the conventional complete denture is also one of important diagnosis tools and transitional repair modes for the edentulous jaw implantation repair.
CAD/CAM (Computer Aided Design/Computer Aided manufacturing) technology is already applied to the field of oral restoration from the 20 th century to the 80 th century, and by utilizing a high-precision digital impression, intelligent restoration special-purpose Aided Design software and a multi-axis numerical control cutting or 3D printing technology, a restoration with more stable quality and more reliable precision can be manufactured, and the technology has more and more deep and wide application in the aspect of fixed restoration. However, the development of the digital technology in the field of complete denture repair is slow, and one of the important reasons is that it is difficult to completely and accurately interpret the clinical concept of key steps such as recording the relationship between the functional pressure impression and the jaw position required by complete denture repair, and high-efficiency digital processing of personalized balanced occlusal tooth arrangement and dentures in a three-dimensional digital quantitative manner.
In recent years, more and more scholars have focused on digital solutions for complete dentures, and complete denture digital repair techniques have been increasingly studied and form a plurality of sets of practically applicable complete denture digital repair systems. The complete denture digital restoration system available at home and abroad currently includes the American AvaDent system, the American Dentca system, the FSD system of the oral hospital of Beijing university in China, the Ceramil FDS system in Germany, the Dentalwings system in Canada, and the 3shape system in Denmark. However, each of the above systems designs the artificial dentition and polished surface appearance of the complete denture by adopting a manual forward construction mode, and the personalized balance occlusal relationship and aesthetic form design effect are still difficult to be accurately and rapidly realized, and the advantages of precision, automation and high efficiency of a three-dimensional digital technology cannot be fully utilized.

In step 102, a target denture template is selected from a complete denture template database based on the alveolar ridge data. The complete denture template database comprises a plurality of standard denture templates, and the standard denture templates can be complete denture scanning data or complete denture design data. In one embodiment, the alveolar ridge data may be fuzzy matched to data in the complete denture template database, resulting in a standard denture template that best matches the patient's alveolar ridge data as the target denture template.

In one embodiment, the operations of tooth arrangement, adjustment, and fusion with the patient's alveolar ridge surface data may be performed on a template basis to obtain complete denture design data. In one embodiment, because the target denture template and the patient's alveolar ridge data are not necessarily a perfect match, fine-tuning may be performed on the basis of the target denture template to improve the accuracy of the complete denture design data.
In the practice of denture fabrication, the inventors have found that the morphology of complete dentures which can be designed and fabricated for different patients according to individual conditions of the patients can be roughly divided into several types, and the complete dentures of the same type have small differences. By the method, the alveolar ridge data of the patient can be matched with the standard denture template data in the template library, so that the standard denture template suitable for the patient is obtained, and further complete denture design is performed based on the template, so that the tedious and complicated manual steps of manually manufacturing the complete denture are replaced, and the automation degree of the complete denture design and the complete denture manufacturing efficiency are improved.
In one embodiment, the acquired alveolar ridge data of the patient may include one or more of arch curve data, base margin line data, and alveolar ridge data.

(2) Measuring the curve distance of the tangent lines between the oral angle lines at two sides of the patient's occlusal embankment, subtracting 4-5mm, comparing with artificial teeth of the same tooth type with various widths, selecting the suitable width of the upper anterior tooth, and selecting the model closest to the standard width.
In the case of no standard wax levee provided clinically, the bilateral crest lines should be drawn first and extended forward and backward, and then the bisector of the incisor papilla (bisection of the labial jaw) should be drawn and extended left and right to intersect the elongation lines of the crest of the alveolar ridge. The distance between the two intersections was taken to determine the anterior tooth width (the two intersections are the medial axis points of the bilateral canines).
According to the selected model of the upper anterior teeth, the model of the lower anterior teeth can be determined in a one-to-one correspondence mode.
When selecting posterior teeth, selecting a distance of 2-5 mm from the far middle of upper incisor teeth (the projection point of the intersection point of the oral angle line and the incisal edge line on the alveolar ridge of the lower jaw moves to the far middle by about 1.5 mm) and the front of the posterior pad of lower molar teeth to confirm the length of 4-7 posterior teeth, and selectively arranging 4 or 7 teeth in fewer rows according to the absorption condition and steep condition of the alveolar ridge so as to obtain the model of the artificial posterior teeth of the patient without the dental jaw.
In one embodiment, upon completion of the manual anterior and posterior tooth model combination, the data may be entered for subsequent screening operations.
In step 203, screening a standard denture template in a complete denture template database according to the obtained combination mode of the artificial anterior and posterior tooth models to obtain a primarily screened denture template; and matching the alveolar ridge data in the initially screened denture template to obtain the target denture template.
