Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of implant denture repair of jaw reconstruction patients, and particularly relates to a preparation method and device of a soft tissue fixing and forming device and a medium. BACKGROUND

[0002] As an important part of occlusal function reconstruction after maxillary and mandibular bone defects, dental implant repair is still challenging. Peri-implantitis is a common biological complication after implantation of jaw defects, which has potential threat to the success of such implant dentures. One of the factors leading to a high incidence of peri-implantitis is that the vestibule is shallow, and the movable oral mucosa or the bulky graft flap covers the alveolar ridge, and it is difficult to form sufficient keratinized gingiva around the implant to form a good biological seal. Therefore, the following soft tissue management methods for implantation of mandibular defects are proposed and recognized by the industry: first, thinning the bulky flap on the top of the alveolar ridge to reduce activity and facilitate its fixation on the alveolar ridge, second, in order to obtain keratinized mucosa tissue with good fixation on the alveolar ridge, the hard palate mucosa is transplanted to the top of the alveolar ridge, and then it is covered and protected by using a method similar to a surgical guide plate or a removable denture, but it will affect the patient's occlusion, and sometimes it is difficult to resist the pulling of the lips and cheek muscles and dislocation, losing the protection effect. Third, the bulky flap on the top of the alveolar ridge is removed, and the granulation tissue is allowed to cover the wound to obtain scar healing, and during this period, iodoform gauze is used to pack and suture to protect the wound, which not only affects the patient's eating, but also has strong discomfort. For other situations where the above soft tissue management measures cannot be taken due to various reasons, when the implantation of the second stage operation is connected to the healing abutment, due to the poor fixation of the alveolar mucosa or the flap, the soft tissue covers the healing abutment, forming a blind bag between them, which is easy to cause soft tissue inflammation, i.e. peri-implant mucositis or peri-implantitis. In summary, there is still a lack of an ideal solution that does not affect the patient's eating, is comfortable to wear, and can achieve the fixation or shaping of the soft tissue around the implant.

[0065] It should be noted that the soft tissue fixation and forming device is used for the soft tissue fixation and forming related to the jaw bone defect implant of the patient.

[0066] In this embodiment, first, the ct data is acquired: the patient with jaw defect implantation takes the dentition ct before the implantation of the second stage surgery, the range includes the upper and lower jaw dentition, the jaw bone or the reconstructed jaw bone and the implant, one is to confirm the good implant bone combination, and the second is to save the ct data in the form of DI COM file for standby.

[0067] At the same time, the scanning data is acquired, which refers to the patient's intraoral dentition and alveolar ridge soft tissue surface morphology data: the patient with jaw defect implantation obtains the intraoral dentition and alveolar ridge surface soft tissue morphology, the occlusal relationship of the upper and lower dentition and other data before the second stage implantation, and the soft tissue range is extended to the vestibule as far as possible to ensure that the soft tissue around the implant can be obtained. If the oral scanning cannot be completed, the conventional intraoral alginate or silicone rubber impression can be taken according to the needs, and then the gypsum model is poured, and the gypsum model is scanned to obtain the above data, and the.stl format file is saved for standby.

[0068] Step S102: fitting based on the ct data and the scanning data to determine the thickness of the soft tissue on the surface of the alveolar bone or the reconstructed jaw bone;

[0069] As an example, the ct data and the scanning data are input in the Zirkonzahn software, the obvious tooth tips in the dentition are selected as the mark points, and the ct data and the scanning data are fitted according to the mark points, so as to determine the thickness of the soft tissue on the surface of the alveolar bone or the reconstructed jaw bone.

[0070] Step S103: generating a virtual implant according to the implant implanted in the patient, fitting the virtual implant and the implant ct to obtain the three-dimensional position of each implant;

[0071] As an example, according to the implant system name and specification implanted in the patient, the same specification virtual implant is selected and inserted in the implant database embedded in the Zirkonzahn software, and the virtual implant and the implant image of the ct are fitted in the coronal plane, the sagittal plane and the axial plane, the boundary of the virtual implant does not exceed the implant image of the ct, so as to obtain the three-dimensional position of the implant.

[0072] Step S104: generating a virtual screw retention abutment according to the thickness of the soft tissue on the surface of the alveolar bone or the reconstructed jaw bone, and determining the abutment gingival penetration position of the virtual screw retention abutment;

[0073] As an example, the abutment height and the gingival penetration position are obtained: according to the thickness of the soft tissue on the surface of the alveolar bone or the reconstructed jaw bone, the same virtual screw retention abutment of the implant system and with appropriate height is selected and inserted in the abutment database embedded in the Zirkonzahn software, and the gingival penetration position of the abutment is determined.

[0074] Step S105: based on the abutment through gingival position, implant three-dimensional position, scanning data, constructing the soft tissue fixation and forming device for jaw bone defect implantation.

[0075] In an embodiment, specifically, the screw channel is determined with the abutment through gingival position as the center, extending about 2mm in each direction, circular or quasi-circular in the occlusal view, and the tissue surface is consistent with the surface soft tissue morphology. The data is saved in stl format.

[0076] In an embodiment, after step S105, the method further comprises:

[0077] Step A: printing the soft tissue fixation and forming device for jaw bone defect implantation to obtain a target device, wherein the target device is used for installing the patient in the implant second stage surgery.

[0078] In an embodiment, the physical object of the soft tissue fixation and forming device for jaw bone defect implantation is made by digital auxiliary production printing or cutting forming as the target device, and then the patient in the jaw bone defect implantation undergoes the dental implant second stage surgery under local anesthesia, connects the appropriate screw retention abutment on the implant according to the design, and performs soft tissue augmentation or flap trimming at the same time. After the above treatment, the target device is fixed with a repair screw with a force of 15Ncm, and it is observed whether the soft tissue is white and cannot be red for several minutes. If so, the soft tissue surface of the target device is ground for one layer until the above problem is solved. The target device is fixed with at least two repair screws with a force of 15Ncm, and is worn in the mouth for 2-8 weeks as needed. During the wearing period, the patient is reexamined to evaluate the healing of the soft tissue around the implant, oral hygiene and screw stability, etc. After the soft tissue heals stably, the target device is removed, and the mouth is scanned or the silicon rubber is molded according to the need, and then the target device is worn in the mouth. After the restoration is made according to the implant denture production process, the target device is removed again, and the restoration is worn.

[0088] In this embodiment, first, the CT data is obtained: the dental arch CT of the patient with jaw defect implant is taken before the implant secondary surgery, which includes the upper and lower dental arches, jaw bones or reconstructed jaw bones and implants. The first is to confirm the good osseointegration of the implant, and the second is to save the CT data in the form of a DICOM file for future use.

[0089] At the same time, the scanning data, that is, the patient's intraoral dental arches and alveolar ridge soft tissue surface morphology data, is obtained: the patient with jaw defect implant obtains the intraoral dental arches and alveolar ridge surface soft tissue morphology before the secondary implant surgery, and obtains the data such as the occlusal relationship of the upper and lower dental arches. The range of the soft tissue taken is extended to the vestibule as much as possible to ensure that the soft tissue around the transgingival position of the implant can be obtained. If the oral scanning cannot be completed, the conventional intraoral alginate or silicone rubber impression can be taken according to the needs, then the gypsum model is cast, and then the gypsum model is scanned to obtain the above data, which is saved in the.stl format file for future use.

[0090] Step S202: Obtain three-dimensional reconstruction data of the dental arches and three-dimensional reconstruction data of the implants based on the CT data;

[0093] As an example, the reconstruction data of the dental arches, the reconstruction data of the implants and the scanning data are input into the Geomagic software, the reconstruction data of the dental arches and the reconstruction data of the implants are regarded as a whole, the obvious landmark points in the dental arches are selected as a reference, and the three-dimensional reconstruction data of the dental arches and the scanning data are fitted to determine the thickness of the soft tissue on the surface of the alveolar bone or reconstructed jaw bone. Each data is saved in the.stl format.

[0094] Step S204: Generate a virtual implant based on the implanted implant of the patient, and fit the virtual implant with the three-dimensional reconstruction data of the implant to obtain the three-dimensional position of each implant;

[0095] As an example, the above data is imported into design software PowerSHAPE, and according to the implant system and specifications implanted in the patient, a virtual implant of the same system and specifications is selected and inserted in the implant database, and the virtual implant and the three-dimensional reconstruction data of the implant are fitted according to the top plane alignment and axis symmetry to obtain the three-dimensional position of the implant

[0096] Step S205: generating a virtual screw-retained abutment according to the soft tissue thickness of the alveolar bone or the reconstructed jaw bone surface, and determining the gingival penetration position of the virtual screw-retained abutment;

Save the data in stl format, use digital auxiliary manufacturing to print or cut and shape, refer to Figure 13 .

[0108] (6) After the completion of the shaping device, the patient is reexamined for implant second stage surgery, and soft tissue treatment is performed at the same time. The implant is connected with the pre-designed screw retention abutment, and the 32, 42, 44, 45, 46 implants are connected with the 4mm high uni abutment. Use the restoration screw to fix the two devices with a force of 15Ncm. The device is successfully positioned during the process, the screw can be pre-tightened to 15Ncm, and the soft tissue is not compressed, refer to Figure 14 .
