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] Example 1: A rhinoplasty material prepared by the following method: the teeth that have been separated from the human body are first immersed 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 use a dental dissection machine to cut the tooth into a leaf shape; connect the demineralized leaf-shaped tooth tissue according to the parameters obtained by the facial model to form a rhinoplasty prosthesis; The rhinoplasty prosthesis is adjusted and ground into the desired personalized prosthesis.

Embodiment 2

[0014] Example 2: A rhinoplasty material prepared by the following method: the third molar of the rhinoplasty subject was cut into a leaf shape with a dental dissection machine, and then soaked in 10% hydrochloric acid for 12 hours to demineralize, and then demineralized for 12 hours. Soak the demineralized tooth tissue in 5% hydrochloric acid for 4 hours; connect the demineralized leaf-shaped tooth tissue to the parameters obtained from the facial model with titanium wire to form a rhinoplasty prosthesis; finally, according to the facial model, the rhinoplasty prosthesis is adjusted and ground 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's requirements for beauty are getting higher and higher. Whether it is a Chinese or a foreigner, there are many people whose nose shape does not meet the aesthetic standards. Therefore, rhinoplasty, which corrects the poor appearance of the nose, has become a popular surgery second only to double eyelid surgery, ranking second in plastic and cosmetic surgery. There are two major types of rhinoplasty filling materials currently used in clinical practice, one is transplantation tissue, and the other is tissue substitutes. The transplanted tissues include: 1. The tissues of the nose itself, such as nasal septal cartilage, nasal alar cartilage, lateral foot, and lateral nasal cartilage tissue. However, these tissues are extremely limited...
