Digital preparation method of intraoral protection device for fixing tooth trauma

Abstract

The invention provides a digital preparation method of an intraoral protection device for fixing a tooth trauma. The digital preparation method comprises the following steps: acquiring impression data of a single-jaw dentition where a digital traumatic tooth is located, and carrying out data modeling; performing 3D printing after data modeling to obtain a single-jaw dentition model; and performing film pressing on the single-jaw dentition model by adopting a double-sided interlayer film to obtain a whole dentition pad serving as the intraoral protection device for fixing the tooth trauma. The digital impression and 3D printing technology is adopted, iatrogenic injuries, caused by a traditional preparation mode, of traumatic teeth are avoided, meanwhile, the tedious steps of tray selection, impression material blending, gypsum casting and model finishing are omitted, the preparation process is simplified, and the cost is saved; The accuracy of the digital impression technology is higher than that of an alginate impression material, the success rate is high, the model can be immediately printed by scanning data after being damaged, repeated intraoral operation is not needed, the medical experience of a patient is good, medical waste is reduced, and environmental protection is facilitated.

Description

technical field [0001] The disclosure relates to the technical field of oral digitalization and 3D printing, in particular to a digital preparation method of an oral protection device for dental trauma fixation. Background technique [0002] The intraoral fixation and protection device used in the treatment of dental trauma is a full dentition fixation for dental trauma Pad, the material used is generally 1.8 ~ 2.5mm thick double-sided sandwich material, one side is soft, as The tissue side of the pad is made of polycarboxylate material; the other side is hard and made of polyacrylate material. Intraoral protection device for tooth trauma fixation is different from traditional orthodontics, surgery or restoration Pads can be used alone for fixation of mixed dentition trauma subluxation, partial luxation, total luxation and permanent dentition subluxation and partial luxation after reduction, and can also be used as other types of dental trauma (such as lateral displacem...

AI Technical Summary

Problems solved by technology

[0012] 1. When removing the impression tray in the mouth, it may cause traumatic loosening and displacement or prolapse of the affected tooth, causing iatrogenic injury;

[0013] 2. When taking an impression in the mouth, it is necessary to pull the lips, put the tray in place and press the gums, etc., which will bring pain to patients with dental trauma accompanied by oral and maxillofacial soft tissue injuries; fluid alginate or edge stimulation of the tray All of them may cause nausea, discomfort, tooth sensitivity and even difficulty in breathing. If the gag reflex is obvious or the children have a short esophagus, they may vomit, which will lead to the risk of coughing and suffocation;

[0014] 3. Temporary fixation of traumatic teeth, selection of trays, mixing of impression materials, casting of plaster, and model trimming are relatively cumbersome steps, and the clinical chairside operation time is long;

[0015] 4. If the patient’s cooperation with the mold is not good enough to change the position when the alginate is solidified or the tray is unreasonable, or the model is damaged during the production of the oral protection device for dental trauma fixation, it is necessary to repeat the operation in the patient’s mouth, and Materials such as impression materials and plaster cannot be reused, resulting in a large amount of medical waste and a waste of medical resources
