Specific embodiment

In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and It is not used in the restriction present invention.

The invention discloses a kind of digitized manufacturing system methods of operation on oral cavity hard and soft tissue protection jaw pad, specifically include following Step:

S1, the layer data that patient's head is scanned by CBCT, sweep parameter 110kVp, 0.7mA, 3.6s scan model It encloses and guarantees to obtain the upper lower jaw of patient by three-dimensional reconstruction software acquisition three-dimensional reconstruction image for eye socket upper limb to inferior border of mandible The DICOM data (Fig. 1) of bone sclerous tissues；

S2, cleaning patient oral cavity, the solid matters such as removal swill are obtained by denture infrared scanning in oral cavity The stl data of the upper mandibular dentition of patient；

S3, completed using open medical image software Pro-plan head 3-dimensional image and denture image superposition, and Using reverse engineering software, according to the region of operation on oral cavity region design protection jaw pad, specifically:

(1) the DICOM data of upper mandibular sclerous tissues and denture stl data are inputted into Pro-plan software, passes through 3D weight Established model carries out mandibular and denture modeling respectively；

(2) according to clearly denture mark point is marked after modeling, the mark point of maxilla denture and mouth are swept into denture Label matched, maxilla and mouth are swept into three image overlaps of denture, and calibrated according to all denture points, until tooth Arrange compound with maxilla perfection, and respectively in Coronal, horizontal position, sagittal plain further confirms that (Fig. 2)；It will according to same procedure Mandibular carries out be overlapped (Fig. 3) with mandibular dentition；

(3) position and the range of upper lower jaw protection jaw pad are designed on 3D model after reconstruction, and in Coronal, axle position, Sagittal plain further confirms that whether protection jaw pad is consistent with design.By the designed upper mandibular comprising including jaw pad part and Denture overlay model exports the preservation of stl file again；

S4, the stl file of preservation is imported in reverse engineering software Geomagic Studio, carries out protection jaw pad 3D mould The design of type, wherein for upper jaw jaw pad using maxillary dentition as template, the lower following jaw denture of gnatho-guide plate is template, and the jaw pad is disk Structure covers entire denture, and occlusal surface is corresponding with upper mandibular dentition, and stinging with depth is 1mm, edge thickness 2mm, upper jaw model It encloses and extends to cheek side gum attached gingiva, palate side extends to the soft or hard palate intersection of palatine, and lower jaw lip side extends to the attachment of cheek side gum Gum, tongue side extend to gum mucous membrane of floor of mouth intersection.It is plane that jaw, which pads tooth and closes the face back side, convenient for connecing when operation with metal openings device It touches (Fig. 4, Fig. 5).

S5, strip poly-lactic acid material is injected in 3D printer barrel, by 3D printer by designed surgical guide 3D model prints, and obtains complete personalized protection jaw pad.

The present invention obtains the upper mandibular sclerous tissues of patient and denture number by combining CBCT and denture to scan 3-dimensional image According to, and data are analyzed, according to the operative region of patient, so that design effectively is suitable for the personalized protection jaw of the patient Pad, to cope with the oral condition under different patient's different conditions；In addition, the present invention is by being overlapped jawbone and denture using computer Three-dimensional reconstruction image the denture other than operative region is chosen, and design the effective range of jaw pad, effectively according to operative region Guarantee the accuracy of maintenance jaw pad；Furthermore the present invention is generated using reverse engineering software and is performed the operation by the personalized jaw pad of design Guide plate data model effectively makes the jaw generated pad data model be suitable for respective patient denture, to protect tooth by jaw pad Column and soft tissue realize the protection to denture and soft tissue, improve operation safety；Finally, the present invention passes through 3D printer for hand The personalized protection jaw pad of art guide plate data model preparation, effectively avoids the damage of universal metal opener, improves art split shed Stability, while avoiding operative region, realize in surgical procedure safely and effectively.

The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
