Embodiment 1
[0031] The specific steps of combining 3D printing and hot pressing film technology described in the present invention are as follows:
[0032] Step 1: Use a 3D scanner to scan the patient's upper dentition to obtain the 3D data of the patient's dental arch outside the body.
[0033] Step 2: Use high-precision silicone rubber to obtain the patient's occlusal record, and record the position of the midline and the mesiobuccal cusp of the left and right first molars. Use a 3D scanner to scan the occlusal record and convert it into digital jaw pad data. To determine the required jaw pad height and the corresponding jaw position for an open bite.
[0034] Step 3: Import the dentition data in Step 1 into Magics software for model restoration, flatten the model gums to make the bottom surface flat, save and export the model STL file;
[0035] Model repair, steps include but not limited to edge trimming of the jaw pad, removal of flash edges, repair of errors such as loopholes, anti-...
Embodiment 2
[0053] (1) Use a three-dimensional scanner to scan the patient's upper dentition to obtain dentition data, that is, the three-dimensional data of the patient's upper dental arch in vitro;
[0054] (2) Obtain the patient's occlusal records, record the midline and the positions of the left and right premolars or the mesiobuccal cusps of the reserved molars, and then use the 3D scanner to scan the occlusal records; to determine the height of the jaw pad required for opening the occlusion and the corresponding position Dental pad position relationship.
[0055] (3) Import the dentition data in step (1) into Magics software for model restoration, cut flat model gingiva to make the bottom surface flat and save it, and export the model STL file;
[0056] (4) Data processing: Import the corrected dentition data in step (3) and the occlusal record data in step (2) into freeform software for jaw pad design: take the occlusal surface as the reference maxillofacial surface, and design in ...
