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 ...

Abstract

The invention discloses a method for preparing an oral functional dental jaw pad by combining a hot pressing membrane and 3D direct printing. The method is characterized by comprising the following steps of acquiring dental arch three-dimensional data and occlusion records of a patient, importing dentition data into 3D image processing software to construct a model, connecting a 3D printer to print and solidify a dentition model, and manufacturing a retention device of the dental jaw pad by adopting a positive-pressure hot-pressing membrane technology and the like. The dental jaw pad is prepared by combining the advantages of elasticity, relatively small thickness and relatively good tooth fitting property of the membrane prepared by the hot pressing membrane technology and the advantage of relatively high precision of the oral functional jaw pad prepared by 3D printing, and has the advantages of rapid and direct forming, short manufacturing period, high precision, low cost, low difficulty and the like; and the manufactured jaw pad can effectively solve the problem of difficult reservation of a tooth lacking gap in the manufacturing process of a replacement dentition jaw pad.

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 Arthritis, slightly harder jaw pads are required, suc...
