3. The controllable range of the hardness of the silicon rubber is large

(1) The hard silicon rubber can achieve enough supporting force for the nose augmentation operation.

(2) The soft silicone rubber can protect the hard silicone rubber, and avoid direct contact between the soft silicone rubber and tissues to cause irritation reaction, red swelling and exudation, and even penetration and infection of severe patients.

(3) Can achieve good tissue simulation hand feeling.

4. The fretwork design of the support network structure can effectively ensure that the nasal septum cartilage is in partial contact with the mucosa, ensure the nutrition supply of the nasal septum cartilage, and avoid the problem that the secondary softening of the nasal septum caused by other products loses the supporting force.

5. The hard silicon rubber of the net-shaped structure of the support can be used as a fixing pile when being sutured and fixed, is not easy to tear, and avoids the cutting problem when costal cartilage is fixed.

6. The integrated design of the nose tip area reduces the complicated processes of building a bracket and moulding the nose tip in the operation. Wherein the hard silicon rubber becomes thinner gradually and extends into the central area of the nasal meatus to disappear, so that the nasal tip area has both supporting force and simulated hand feeling.

7. The nose tip area is in a Y-shaped form, and the two side walls are cambered surfaces which are inwards concave, so that the cambered form at the top end of the nostril is favorably maintained, and the hard sharp corner deformity is avoided.

8. The three-dimensional structure of the triangular pyramid in the subnasal point area is strong and powerful, and can better maintain the columella nasi area to be neutral position, thereby avoiding the askew condition of the columella nasi.

9. The integrated into one piece design of extension of point district to the foot under the nose can effectively lift the point under the nose, improves nasolabial angle, nose point drapability, more is favorable to nasal part aesthetic form.

Of course, it is not necessary for any particular product to achieve all of the above-described advantages simultaneously.
