Embodiment 1
[0028] An easily detachable dental bonding stick, comprising a handle 1 and an adhesive 3, the adhesive 3 is fixed on the handle 1 through a connecting body 2, and the material of the adhesive 3 is hydrogel.
[0029] The usage method of this embodiment is: use the adhesive glue of the bonding stick to fix the dental restoration, and then place the dental restoration on the teeth. When the adhesive between the dental restoration and the tooth is initially solidified, use a dental probe dipped in a small amount of water to destroy the connection between the dental bonding rod and the dental restoration, and then the dental bonding rod and Dental restorations isolated.
Embodiment 2
[0031] This embodiment provides that this embodiment provides a method for preparing a hydrogel for Example 1, comprising the following steps:
[0032] Step 1: Mix 20 parts of polyimide, 2 parts of ammonium persulfate, 0.01 part of N,N-methylenebisacrylamide and 30 parts of water according to parts by mass to obtain a mixed solution for later use;
[0033] Step 2: According to the volume ratio of 1:1.2, add a dopamine aqueous solution with a pH of 9 and a concentration of 3g / L to the mixed solution prepared in Step 1, and stir evenly in an ice-water bath for 20 minutes to obtain a soft tissue repair material for use;
[0034] Step 3: put the soft tissue repair material in step 2 into vacuum drying, and dry at 37° C. for 6 hours to obtain a soft tissue repair layer.
Embodiment 3
[0036] This embodiment provides that this embodiment provides a method for preparing a hydrogel for Example 1, comprising the following steps:
[0037] Step 1: Mix 28 parts of silk fibroin, 3 parts of ammonium persulfate, 0.03 parts of N,N-methylenebisacrylamide and 50 parts of water according to parts by mass to obtain a mixed solution for later use;
[0038] Step 2: according to the volume ratio of 1:1, add a dopamine aqueous solution with a pH of 10 and a concentration of 4g / L to the mixed solution prepared in step 1, and stir evenly in an ice-water bath for 15 minutes to obtain a soft tissue repair material for subsequent use;
[0039] Step 3: put the soft tissue repair material in step 2 into vacuum drying, and dry at 37° C. for 6 hours to obtain a soft tissue repair layer.
