Individualized nasal base shaping device and making method thereof

Abstract

The invention discloses an individualized nasal base shaping device and a making method thereof. The making method includes steps: collecting data: collecting three-dimensional data of facial soft tissue of a patient under different postures; remodeling: rebuilding a virtual three-dimensional model for the facial soft tissue of the patient according to the collected data; determining a boundary: drawing a range curve for the shaping device according to the rebuilt three-dimensional model of the soft tissue, determining the curve as the boundary of the shaping device, and generating thickness of the shaping device according to the boundary, wherein the different postures include at least one of sitting position, standing position, supine position and lateral decubitus position. The shapingdevice can realize retention by utilizing own undercut, and a breathing hole is formed in the shaping device; by utilizing the shaping device made by the method after an operation, through action of mechanical force, and postoperative nose wing widening and nasal columella collapse of an orthognathic patient can be relieved to maintain preoperative state of nose wing and nasal columella.

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...

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
