[0117] The following is a description of the method of preparing an orthodontic component according to the present invention.
[0118] First, a water-soluble or biodegradable material is mixed with pure water, thereby preparing a composition for an orthodontic member (step a).
[0119] The composition for an orthodontic member may further include a compound represented by Chemical Formula 1 below.
[0120] [chemical formula 1]
[0121]
[0122] In Chemical Formula 1, n is any integer of 1-8.
[0123] Step (a) is to prepare the composition by mixing gelatin, glycerin, sorbitol solution and purified water. The solvent of the sorbitol solution can be water.
[0124] The water-soluble or biodegradable material may be a compound represented by Chemical Formula 2 below.
[0125] [chemical formula 2]
[0126]
[0127] In Chemical Formula 2, R is independently a hydrogen atom, a deuterium atom, a C1-C6 alkyl group or a C1-C6 hydroxyalkyl group, n is a repeating unit, and th...

[0146] Preparation Example 1: Preparation of Coating Solution
[0147] 430 parts by weight of gelatin (manufactured via Geltech, 250 bloom) was dispersed in 390 parts by weight of water, and then 140 parts by weight of glycerin was added thereto and mixed therewith. Subsequently, 5 parts by weight of a sorbitol solution (70% concentration) dissolved in water was added and uniformly dispersed. Subsequently, the gelatin was dissolved at 90° C. for 60 min and defoamed at 65° C. under a vacuum of 700 mmHg for 30 min. The defoamed solution was cured at 60° C. for 6 hours to prepare a coating solution.

[0148] Preparation Example 2: Preparation of Coating Solution
[0149] The coating solution was prepared using hydroxypropylmethylcellulose (HPMC) having a viscosity of 6 mPa·s in a 2 wt % aqueous solution. 585 parts by weight of pure water and 1 part by weight of potassium sorbate were added and mixed together, and the resulting solution was heated to 90°C. 220 parts by weight of HPMC and 194 parts by weight of ethanol were added to the solution at 90° C. and mixed for 2 h, thereby dissolving the HPMC. The prepared composition was cured at 55° C. for 12 hours to obtain a coating composition for orthodontic components.
