Example 1

As shown in fig. 1 to 12, the digital tooth arrangement guide plate of the present invention comprises an injection molding hole 1, an observation hole 2, a first positioning area 3, a transfer area 4 and a second positioning area 5, wherein the specific structure and connection relationship are as follows:

the tooth form of 1 tooth form of the adjacent area on the left side of the restoration area is taken as a first positioning area 3 in the first positioning area 3, the tooth form of one tooth form or the alveolar ridge part area of the adjacent area on the right side of the restoration area is taken as a second positioning area 5 in the second positioning area 5, the full tooth form and the base gum form of the restoration area are taken as transfer areas in the transfer area 4, the first positioning area 3 and the second positioning area 5 are respectively positioned on the left side and the right side of the transfer area 4, the first positioning area 3 and the second positioning area 5 are connected with the transfer area 4, the detection hole 2 is positioned above the tooth of the transfer area 4, and the injection molding hole 1 is positioned above the base of the transfer area 4.

The use method of the digital tooth arrangement guide plate comprises the following steps:

1. as shown in fig. 7, resin teeth are placed at the tooth positions in the transfer area 4;

2. as shown in fig. 8, the fit between the finished resin tooth and the guide plate was confirmed through the inspection hole;

2. as shown in fig. 9, the excess resin root excess is removed;

3. taking down the bracket and the guide plate, and coating a dental separating agent on the model and the guide plate;

4. as shown in fig. 10 to 13, the first positioning area 3 and the second positioning area 5 are reset to the corresponding areas of the working model, melted denture wax or mixed denture polymer is sucked by a syringe, and after cooling or solidification, the tooth arrangement guide plate is separated and taken out, so that the full tooth form and the denture gum form of the restoration area can be transferred to the crown of the model.

The structure principle is as follows: the tooth arrangement data of the designed restoration area is transferred out by a transfer area 4 on the corresponding model three-dimensional data, the operation position of the digital porcelain-applying guide plate is positioned by collecting the data of a first positioning area 3 and a second positioning area 5 of adjacent areas, the specific structure of the working model is determined according to the oral cavity condition of each patient, and the working model is personalized and has no uniform standard structure.

Model data are scanned through a D2000 scanner of the 3shape, a bracket of the movable partial denture and teeth are arranged on the digital model through digital design software of the 3shape, and the 3shape software can accurately arrange the radian of the dental arch and accurately control the area of a contact area between the resin teeth and the jaw. And designing gingiva and a guide plate by using EXOCAD digital design software on STL data of the bracket and the tooth arrangement designed by the 3shape software. The tooth arrangement technician copies the tooth arrangement data to a real model by using the guide plate, can accurately control the occlusion relation, the arch radian and the gum form of the restoration area without too much experience, and reflects the designed data by using a digital cutting machine or 3D printing equipment and the like in a transfer device mode of the digital tooth arrangement guide plate so as to achieve the effect of accurately controlling tooth arrangement.
