Personalized nose base shaper and manufacturing method thereof

Abstract

The invention discloses an individualized nasal base shaping device and a manufacturing method thereof. The manufacturing method includes: a data collection step: collecting three-dimensional data of the facial soft tissue of the patient in different postures; a model reconstruction step: reconstructing the patient's facial soft tissue according to the collected data virtual three-dimensional model; and boundary determination step: according to the reconstructed three-dimensional model of soft tissue, draw the curve of the range of the shaper, and determine the curve as the boundary of the shaper, and then generate the thickness of the shaper according to the boundary; the different postures include At least one of sitting position, standing position, supine position, and lateral position; the individualized nasal base shaper can be retained by its own undercut and the individualized nasal base shaper is designed with ventilation holes; after the operation The nasal base shaper produced by the production method of the present invention can reduce the widening of the nasal alar and the collapse of the nasal columella of orthognathic patients after operation through the action of mechanical force, so as to maintain the preoperative state.

Description

technical field [0001] The invention relates to a nose wing and nostril shaper, in particular to an individualized nasal base shaper and a manufacturing method thereof. Background technique [0002] Orthognathic surgery is an important method for correcting dentofacial deformities clinically, and maxillary Le Fort I osteotomy is one of the most commonly used procedures. However, during the operation, the attachments of the transversus nasimus, orbicularis oris, levator labii, and levator angle oris muscle attached to the anterolateral wall of the maxilla in the nasolabial region need to be stripped, resulting in contraction of these muscles to the sides or the center. Ultimately, the soft tissue in the nasolabial area is displaced laterally. Therefore, while correcting the deformity of the jaw, this surgery often causes changes in the shape of the nasal base, including widening of the alar base and shortening of the nasal columella, which are not conducive to aesthetic chan...

AI Technical Summary

Problems solved by technology

However, during the operation, the attachments of the transversus nasimus, orbicularis oris, levator labii, and levator angle oris muscle attached to the anterolateral wall of the maxilla in the nasolabial region need to be stripped, resulting in contraction of these muscles to the sides or the center. Eventually leading to lateral displacement of the soft tissue in the nasolabial region

Therefore, while correcting the deformity of the jaw, this surgery often causes changes in the shape of the nasal base, including widening of the alar base and shortening of the nasal columella, which are not conducive to aesthetic changes. Currently, there are no good clinical treatment measures. It is usually prevented by suture suspension in the operation, but the effect is not very satisfactory
