Embodiment Construction

[0061] The technical solution of the present invention will be described in detail below in combination with the embodiments and the accompanying drawings.

[0062] The method for generating an osteotomy guide plate for zygomatic bone and zygomatic arch plastic surgery according to the present invention, its flow chart can be found in figure 1 , including the following steps:

[0063] Step 1. Perform spiral CT examination on the patient's head to obtain CT data, and import the CT data to establish a 3D model of the craniofacial bone.

[0064] In order to illustrate the parameter requirements of CT examination, in this step, when performing spiral CT examination on the patient's head, the parameters of CT examination are preferably: the matrix size is 512×512, the slice thickness is less than or equal to 1.0 mm, and the slice distance is less than or equal to 1.0 mm, the layer distance is equal to the layer thickness, the reconstruction algorithm is High resolution standard al...

Abstract

The invention relates to a template manufacturing technology, and provides an osteotomy guide plate for a cheekbone and zygomatic arch plastic surgery and an internal pushing guide plate generation method in order to solve the problem that no special osteotomy guide plate or internal pushing guide plate exists in the existing cheekbone and zygomatic arch plastic surgery. The technical scheme can be summarized as follows: establishing a 3D model of a cranio-maxillofacial bone according to the head of a patient; designing an osteotomy line, performing simulated osteotomy and inward pushing according to requirements to obtain a simulated scheme, importing the simulated scheme, and generating an osteotomy guide plate attached to the anatomical morphology surface of an osteotomy in the simulated osteotomy scheme through a surface stretching function; then enabling the osteotomy guide plate to at least extend to the lower surface of an orbital space and a zygomatic alveolar ridge surface to obtain required osteotomy guide plate data, and designing an internal pushing guide plate to obtain required internal pushing guide plate data, and obtaining the osteotomy guide plate and the internal pushing guide plate through rapid prototyping and a 3D printing technology. The method has the beneficial effects that the osteotomy guide plate and the inner pushing guide plate of a patient can be conveniently and quickly generated. The method is suitable for generating the osteotomy guide plate and the inner pushing guide plate for the zygomatic bone and zygomatic arch plastic surgery.

Description

technical field [0001] The invention relates to template manufacturing technology, in particular to the manufacturing technology of an osteotomy guide plate and an inner derivation guide plate for zygomatic bone and zygomatic arch plastic surgery. Background technique [0002] Zygoma and Zygomatic Arch Protrusion Correction, also known as Zygomatic Bone and Zygomatic Arch Reduction, Zygomatic Bone Lowering and Zygomatic Bone Reduction, is an important field of maxillofacial cosmetic surgery. The goal of zygomatic bone and zygomatic arch plastic surgery should be achieved: the newly formed zygomatic face should have a natural and smooth contour to achieve harmony and symmetry with the upper and lower parts of the face, and there should be no traces of surgery on the appearance. Not only does the face conform to the prevailing aesthetic standards in both frontal and side views, but it also appropriately meets the individual aesthetic demands of the beauty seeker. Personalized...
