Problems solved by technology

[0007] In view of the above problems, the present invention provides a method for preparing oral functional dental and jaw pads by combining hot-pressing film technology and 3D direct printing, and preparing oral functional dental and jaw pads by combining hot-pressing film technology and 3D direct printing, which overcomes the existing traditional functional pad preparation. The process is complex, difficult, large in size and uncomfortable to wear, etc.; the preparation of dental and jaw pads with short clinical operation time, simple process, small size, easy to remove and wear, and accurate occlusion can meet clinical needs; Soft and high warhead, suitable for the needs of the target group

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, the steps include but are not limited to jaw pad edge trimming, flash removal, loopholes, anti-triangular and bad edge repairs. ...

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 ...

Abstract

The invention discloses a method for directly preparing oral functional dental and maxillary pads by combining hot-pressed film and 3D printing. Connect the 3D printer to print and solidify the dentition model, and use the positive pressure hot-pressed membrane technology to make the retention device of the jaw pad and other steps. The invention combines the advantages of elasticity, thinner thickness and better tooth fit of the diaphragm made by hot-pressed film technology, and the advantages of high precision in preparing oral function jaw pads by 3D printing to prepare dental jaw pads, which has the advantages of rapid and direct molding , short production cycle, high precision, low cost, less difficulty, etc., and the manufactured jaw pad can effectively solve the rare problem of reserving gaps for missing teeth in the process of manufacturing jaw pads for dentition.

Description

technical field [0001] The invention belongs to the field of oral surgery, and in particular relates to a method for preparing oral functional dental and jaw pads by combining hot-pressed film technology and 3D direct printing, which can be quickly and directly formed, and is suitable for clinical orthodontics, restoration, joints, oral and maxillofacial, etc. Background technique [0002] Dental pad technology has always been an important part of oral clinical use. The clinical application of dental pads in oral cavity is mainly distributed in the diagnostic restoration of jaw position, exclusion of occlusal interference, jaw position treatment, etc., especially in oral joints, orthodontics, restoration The most common treatment in oral and maxillofacial surgery. [0003] At present, the clinical application of dental and maxillary pads in the oral cavity mainly involves the following aspects ① In the department of oral and joint joints, slightly harder jaw pads are require...
