The effect of prosthetic rhinoplasty is very natural. Doctors can vividly show the effect of rhinoplasty for beauty seekers in three-dimensional space, and beauty seekers can also make suggestions to doctors according to their own aesthetics, so as to better meet the requirements of beauty seekers and obtain a natural beautiful nose. According to the deformation of soft tissues in different rhinoplasty areas, combined with the digital expert experience library, the prosthesis conforms to the personality characteristics of beauty seekers in shape and fits stably, and the rhinoplasty effect after implantation is completely consistent with the simulation effect. Traditional rhinoplasty needs to carve the prosthesis by hand, but we don't know the shape of the nasal bone of the beauty seeker. It is difficult for the prosthesis to fit the nasal bone completely, which may easily lead to sliding, dislocation, deviation and stepped deformity of the nasal root. The shape of digital prosthesis comes directly from the nasal bone model reconstructed by computer, and the thickness of prosthesis is analyzed by analyzing the difference between the simulation effect and the original nasal shape.
