Problems solved by technology

However, hydroxyapatite cannot be formed before the operation. It can only be gently squeezed and pressed with fingers to form the desired shape during the insertion process. It requires certain experience, and it takes a long time to solidify after implantation, and it is easy to deform when subjected to external force. In addition, granular hydroxyapatite is easy to move in the nose

Embodiment 1

[0013] Embodiment 1: A kind of rhinoplasty material, made by the following method: the tooth that has been separated from the human body is first soaked in hydrochloric acid with a concentration of 20% (volume percentage, the same below) for 8 hours, and then demineralized in 6% hydrochloric acid. Soak and demineralize for 5 hours; then cut the tooth body into leaf shape with a tooth cutter; connect the demineralized leaf-shaped tooth tissue with titanium wire to form a rhinoplasty prosthesis according to the parameters obtained by taking a facial model; The rhinoplasty prosthesis is adjusted and ground into the desired personalized prosthesis.

Embodiment 2

[0014] Embodiment 2: a kind of rhinoplasty material, is made by following method: the third molar of rhinoplasty object is cut into blade shape with dental cutter, then soaks demineralization in 10% hydrochloric acid for 12 hours, then in 7 % hydrochloric acid for 4 hours; the demineralized blade-shaped tooth tissue was connected with titanium wires to form a rhinoplasty prosthesis according to the parameters obtained by taking the facial model; finally, the rhinoplasty prosthesis was adjusted to the desired Personality prosthesis.

Abstract

The present method of nose-lifting material includes the following steps: soaking the tooth separated from human body in hydrochloride acid whose concentration is 5%-20% to make demineralization, then cutting the tooth body into leaflet from or firstly cutting the tooth body into leaflet form, then soaking it in hydrochloric acid to make demineralization; the connecting the demineralized leaflet tooth tissue into hump nose prosthesis by means of titanium wire; finally regulating and grinding the hump nose prosthesis into individual prosthesis according to the facial model. Said invention uses human tooth as main raw material, the decalcified tooth body can be arbitrarily moulded according to the requirment, and possesses good tissue compatibility, and possesses good affinity with peripheral tissue, after it is transplanted, it is not easy to be absorbed.

Description

technical field [0001] The invention relates to a rhinoplasty material and a preparation method thereof. Background technique [0002] Plastic and cosmetic surgery is an important part of medical science. With the improvement of material life, people have higher and higher requirements for beauty. Whether Chinese or foreigners, there are quite a few people whose nose shape does not meet the aesthetic standards. Therefore, rhinoplasty to correct the bad appearance of the nose has become a popular surgery after double eyelid surgery, ranking second in plastic surgery. At present, there are two types of filling materials for rhinoplasty clinically used, one is transplanted tissue, and the other is tissue substitute. The transplanted tissues include: 1. The tissues of the nose itself, such as the nasal septal cartilage, the lateral crus of the alar cartilage, and the lateral nasal cartilage tissue. However, these tissues are extremely limited and are only suitable for fillin...
