Description

Technical Field

[0001] The present invention belongs to the technical field of suture distraction, and in particular relates to a design method and system of an integrated titanium plate component for traction of an external support for suture distraction in an auxiliary plane. Background Art

[0002] Midface hypoplasia is a common developmental deformity of the craniofacial region, most commonly seen in patients with congenital cleft lip and palate. It is mainly manifested by skeletal Class III malocclusion, accompanied by flatness or even depression in the paranasal, infraorbital, and zygomatic regions. It is a three-dimensional dysplasia of the midface skeleton, often accompanied by narrow maxillary dental arch, crowded and disordered dentition, missing teeth, and true or false overgrowth of the mandible. Midface depression often appears in the patient's childhood and progressively worsens with growth and development, affecting the patient's pronunciation and chewing function, and even causing psychological disorders in the patient, affecting his physical and mental health. This deformity lacks early and effective treatment methods. In the past, the main intervention measures were orthodontic face bow traction and orthognathic surgery. However, the orthodontic face bow traction has limited effect, and the traction device is difficult to fix in the mouth of patients in the deciduous or replacement period, which can easily cause loss of anterior tooth anchorage. About 25% of patients still require combined surgical treatment. It is generally believed that orthognathic surgery can only be performed after the patient reaches adulthood, completely missing the progression of the disease and allowing the development of the deformity. Suture distraction is achieved by surgically inserting a traction hook into the patient's maxillary bone. The strong support of an external skull stent applies traction to the patient's entire mid-face skeleton, promoting suture growth and bone formation, and ultimately achieving the treatment of mid-face dysplasia.

[0003] However, due to the large differences in facial deformities among each patient, there is currently no scientific means of personalized customization, and it almost entirely depends on the doctor's experience, which may lead to unsatisfactory postoperative results. Summary of the invention

[0047] First embodiment

[0048] This embodiment provides a method for designing an integrated titanium plate assembly for assisting mid-surface suture distraction external bracket traction, comprising:

[0049] Scanning the target object by a medical scanning device to obtain a three-dimensional model of the internal structure and tissue of the target object, wherein the three-dimensional model at least includes a bone structure and a tooth tissue that can be displayed independently;

[0050] Performing bone analysis on the bone structure of the target object based on the three-dimensional model to obtain weak points of the bone structure;

[0051] Acquire the root position of the tooth tissue of the target object based on the three-dimensional model;

[0052] Determine the osteotomy position 3 and select the shape and size of the integrated titanium plate component model based on the bone analysis results, and determine the fixing hole position of the integrated titanium plate component model based on the root position;

[0053] A three-dimensional model of the integrated titanium plate assembly is generated based on the shape, size and fixing hole positions of the integrated titanium plate assembly model.

[0054] The technical solution of this embodiment uses a medical scanning device to scan the patient's head, and can obtain a model of the patient's bone structure and various tissues, providing a data model for the subsequent design of an integrated titanium plate assembly. The integrated titanium plate assembly designed based on this can better fit the bone surface, thereby improving the postoperative effect. Specifically, it is necessary to avoid the weak points of the bone wall and the position of the tooth root of the bone structure during design. Therefore, after adjusting the software threshold analysis to obtain the weak points of the patient's bone wall and the root position, they can be effectively avoided to prevent poor postoperative traction effects or damage to the root. See Figure 1 is a schematic diagram of the integrated titanium plate 1 designed and generated by the method being installed at the target position, and the osteotomy position 3 is Figure 1 At the junction of the yellow and white bones, the yellow bone block outside the osteotomy position 3 is the bone block pulled out by distraction of the present invention.

[0055] Preferably, the method further comprises generating a three-dimensional model of the first pre-fixation plate and the second pre-fixation plate based on the bone analysis results, the shape and size of the integrated titanium plate assembly model, and the position of the fixation holes:

[0056] Determine the shape and position of the piriform foramen and zygomatic alveolar ridge of the target object based on the bone analysis results to determine the shape and coordinates of both ends of the first pre-fixation plate and the second pre-fixation plate, and determine the shape and size of the three-dimensional model of the first pre-fixation plate and the second pre-fixation plate according to the shape and size of the integrated titanium plate assembly model;

[0057] Pre-fixing hole positions are formed at corresponding positions on the first pre-fixing plate and the second pre-fixing plate based on the fixing hole positions.

[0058] See also Figure 2 The technical solution of this embodiment also generates a three-dimensional model of the first pre-fixation plate and the second pre-fixation plate to obtain the first pre-fixation plate and the second pre-fixation plate, so that before the integrated titanium plate assembly is fixed on the patient's bone, the first pre-fixation plate and the second pre-fixation plate are first used to fix the patient's bone, and the two ends are respectively suitable for snapping into the piriform hole and the zygomatic alveolar ridge, and then pre-fixed on the patient's bone through the positioning through hole, and then the first pre-fixation plate and the second pre-fixation plate are retrieved, and then the integrated titanium plate assembly is placed according to the pre-fixed position, and fixed to the bone through multiple fixing holes, thereby preventing the problem of position deviation caused by direct fixation with the integrated titanium plate assembly. And the first pre-fixation plate and the second pre-fixation plate are designed based on the patient's bone structure and tooth tissue three-dimensional model, so as to improve the matching accuracy of the pre-fixation plate and the integrated titanium plate assembly, which is conducive to the overall surgical traction accuracy and effect.

[0059] Preferably, performing bone analysis on the skeletal structure of the target object based on the three-dimensional model further comprises:

[0061] When the number of marked pixel units within the preset range reaches a second threshold, the preset range is marked as a weak point of the bone structure.

[0062] The technical solution of this embodiment can obtain the bone thickness of each pixel unit based on the patient's bone structure model obtained by scanning. If the thickness is less than the first threshold, it will be marked. The first threshold here can be determined according to the actual situation of the patient. Because different patients have different ages, deformity types, deformity degrees, etc., the threshold may vary greatly. When the number of marked pixel units within a certain range reaches the second threshold, it is determined to be a weak point in the bone structure.

[0063] Preferably, determining the position of the fixing hole of the integrated titanium plate assembly model based on the tooth root position further includes:

[0064] Segment the maxillary and mandibular bones and tooth roots according to the patient's CT threshold;

[0065] The tooth root position coordinates in the system are read, and a plurality of fixing holes are determined on the first fixing plate and the second fixing plate of the integrated titanium plate assembly model, the distance from the tooth root coordinate position being greater than a third threshold and avoiding the weak points of the bone structure.

[0066] The technical solution of this embodiment aims to effectively avoid the tooth root position during design, prevent damage to the patient's tooth root, and avoid other adverse effects on the patient.

[0069] After generating the three-dimensional model of the integrated titanium plate assembly, the 3D printing device is driven to print the integrated titanium plate assembly.

[0070] The technical solution of this embodiment determines the coordinates of the fixing holes after considering the weak points of the bone wall and the damage to the tooth roots as mentioned above, and then fuses the shape and size of the integrated titanium plate assembly model with the positions of the fixing holes to obtain a three-dimensional model of the integrated titanium plate assembly, which is then imported into a 3D printing device for printing to finally obtain an integrated titanium plate assembly.

[0071] Preferably, the method further comprises:
