Titanium alloy embedded tooth individual traction accessory printed through three-dimensional technology

Abstract

The invention relates to the technical field of medical treatment, in particular to a titanium alloy embedded tooth individual traction accessory printed through a three-dimensional technology. According to the titanium alloy embedded tooth individual traction accessory printed through the three-dimensional technology, according to the best traction pulling path for an impacted tooth, an adhesionpart and the traction direction of the traction accessory are designed, and the best specific part of a main traction accessory body and the best position of a traction hook are determined. Based on atitanium alloy material, according to the best design scheme for the traction accessory device, the main traction accessory body and the traction hook which completely fit the corresponding tooth surface are printed, wherein the main traction accessory body and the traction hook are integrally formed. The main traction accessory body and the traction hook can completely fit the tooth surface, andafter adhesion, the main traction accessory body and the traction hook cannot easily fall; compared with traditional stainless steel, the titanium alloy material is significantly excellent, the phenomenon of the soft and sclerous tissue inflammatory reaction cannot easily occur; the integrated structure is firmer, and the phenomenon of fracturing cannot easily occur.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a three-dimensionally printed titanium alloy individualized traction accessory for embedded teeth. Background technique [0002] An impacted tooth is a very common developmental abnormality in clinical oral diseases, which is likely to cause a series of complications, such as recurrent pericoronitis, caries of adjacent teeth, tilt, accelerated deformity recurrence after orthodontics, food impaction, oral Odors and more. Ordinary impacted teeth can be extracted surgically, but the risk of direct extraction of impacted teeth that are closely related to important organizational structures such as the inferior alveolar neurovascular bundle, maxillary sinus cavity, and nasopalatine nerve is high.

AI Technical Summary

Problems solved by technology

Ordinary impacted teeth can be extracted surgically, but the risk of direct extraction of impacted teeth that are closely related to important organizational structures such as the inferior alveolar neurovascular bundle, maxillary sinus cavity, and nasopalatine nerve is high. Surgical exposure combined with orthodontics Traction is one of the best treatments

In the past treatment, the finished traction device was used, which was easy to fall off, and the position of the traction action was not easy to determine, and the direction could not be controlled, etc.

[0003] Existing problems specifically include: First, the traction design is often out of touch with the surgical fenestration position, and the orthodontist can only glue the accessories and determine the traction direction according to the surgeon’s fenestration position after surgery; operations often need to be done under blind vision, Remove a large amount of bone to find a relatively flat tooth surface that is conducive to bonding, and sometimes the exposed position is not conducive to traction treatment

Second, improper traction direction may result in loss of attached gingiva or marginal bone or failure of traction

In addition, most of the clinically used traction devices are finished lingual buckles, brackets or temporary bent parts, which cannot fit the tooth surface of the impacted teeth optimally, have low shear resistance, and the traction devices often fall off. Secondary surgery, rebonding the traction device, increases the trauma, pain and cost of the patient, and is prone to doctor-patient disputes

Finally, the thickness of the lingual buckle or the bracket cannot be changed. For the case where the exposed surface is deep, it is easy to compress the gums during traction and cause inflammation, etc.
