Embodiment Construction

[0044] A method for making a surgically oriented template for repairing a mandibular defect with a fibula flap, comprising the following steps:

[0045] 1) The image data collection of the patient's jaw and fibula. The data can be collected by means of CT, MRI and the like. Taking CT as an example, spiral CT thin-slice scanning can be used, and the tomographic data can be stored in a storage device in DICOM format after scanning.

[0046] 2) Three-dimensional model reconstruction of the jaw and fibula. Import the stored image data into medical design software, such as Mimics from Materlise or 6D software from Hangzhou Liuwei Company and other software with similar functions. Here, the 3D reconstruction of the jaw image and the fibula image are performed separately. Analyze and determine the patient's diseased area in the software, propose a preliminary jaw resection plan, and determine the fibula of the left or right foot as the target fibula for fibula flap transplantation r...

Abstract

The invention discloses a manufacturing method for a fibular flap repairing mandible defect operation guiding template. The manufacturing method for the fibular flap repairing mandible defect operation guiding template comprises the steps that a mandible three-dimensional model and a fibula three-dimensional model are rebuilt, a lesion area is determined, and the target fibula is determined; the lesion area is excised, and a jaw non-lesion area model and a lesion area model are saved; the inner surface of a jaw cutting locating guiding template is attached to the outer surface of the lesion area model; the area where the fibula three-dimensional model and fibula subsection models are placed is partitioned to form a fibula repairing area; the inner surface of a fibula molding guiding template is entirely attached to the cheek side surface of the fibula repairing area; the inner surface of a fibula cutting locating guiding template is entirely attached to the outer surface of the corresponding fibula subsection model; the jaw cutting locating guiding template, the fibula molding guiding template and the fibula cutting locating guiding template are molded. The fibular flap repairing mandible defect operation guiding template and the manufacturing method have the advantages that the bone cutting scheme of the fibula and the molding position of each section of the fibula can be accurately controlled, the precise implement of a fibular flap transplanting repairing mandible defect operation is guaranteed, the operation time is shortened for the fibular flap repairing mandible defect operation.

Description

technical field [0001] The invention relates to a surgical guide template for dental surgery and a manufacturing method of the template, in particular to a manufacturing method of a surgical guide template for digitally navigating a fibular flap to repair mandibular defects. technical background [0002] Mandibular defects are mostly caused by diseases such as tumors, trauma, inflammation, and bony joint ankylosis. Mandibular defects directly affect the oral function and appearance of patients. The mandible is the largest bone in the face, the main supporting structure of the facial shape, and the only movable bone in the face. The mandible is the main site responsible for chewing and speech functions. The purpose of mandibular defect treatment is to rebuild the integrity of the mandible, restore its shape and function, and improve the patient's survival and quality of life. [0003] Since Hidalgo used the fibula flap for the repair and reconstruction of maxillofacial defe...
