Embodiment 1
[0049] In view of the fact that the existing isolated tooth models are not perfect enough to restore model teeth with thick root canals, this embodiment is optimized to solve the problems existing in the existing models.
[0050] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, this embodiment discloses an affected tooth model for simulating root canal barrier surgery in vitro, including a model affected tooth 1 and a base 2, the model affected tooth 1 and the base 2 are movably connected, and the model affected tooth 1 is placed on the base The inside of the seat becomes the whole tooth model. The model affected tooth 1 is provided with a model single canal simulating the thick root canal of the affected tooth, and the size of the apical foramen 14 simulates the common immature thick single root canal of the affected tooth in clinical practice. The base is provided with a space (embedded hole 21) for accommodating the single canal root of the model, and a hem...
Embodiment 2
[0056] The content of the above-mentioned embodiment 1 discloses the structure of the affected tooth model for in vitro simulation of the root canal barrier technique, and this embodiment also discloses the method for constructing the affected tooth model of the root canal barrier technique, which is now specifically described:
[0057] Step 1: Scan the isolated tooth by CBCT, obtain the data in DICOM format of the isolated tooth and convert it into an editable 3D data format (such as STL format), according to the clinically measured thick root canal and immature apex For the root length and the size of the apical foramen of the affected tooth, the shape of the root canal of the corresponding size is designed in the 3D software, and after the design is completed, it is imported into the 3D printer to make a model of the affected tooth;
[0058] Step 2: According to the designed model of the affected tooth, design the corresponding base in the 3D software that can just accommoda...
