Description

Technical Field

[0001] The present invention relates to the technical field of dentistry, and particularly relates to a personalized assistance system for oral implantation. Background Art

[0002] Oral implantation refers to a tooth restoration method that supports and retains the upper tooth restoration based on the lower structure implanted in the bone tissue. It includes two parts: the lower support implant and the upper tooth restoration. It uses artificial materials to make the implant, which is implanted into the upper and lower jaws through surgical methods and obtains firm retention and support from the bone tissue, and connects and supports the upper tooth restoration through special devices and methods. Dental implants can obtain a restoration effect that is very similar to the function, structure, and aesthetic effect of natural teeth, and have become the preferred restoration method for more and more toothless patients.

[0003] In dental implant surgery, the implant position, direction, and depth of the dental implant are the key factors affecting the success of the surgery. Traditional dental implant surgery is carried out based on the doctor's personal experience, which may lead to phenomena such as bone fracture in the implant area, perforation of the lateral wall of the alveolar bone, and root nerve injury. At present, with the development of technology, oral implant surgery guided by a digital dynamic real-time navigation implant system has gradually replaced traditional dental implant surgery. The digital dynamic real-time navigation implant system uses three-dimensional medical images to fuse the patient's jaw position, implant handpiece position, and drill bit position, avoid the root nerve, and combine active infrared positioning technology to achieve the fusion of surgical instruments, medical images, and human spatial positions. Therefore, during the surgery, the system can present the patient's anatomical structure in real time, monitor the implant site, angle, and depth throughout the process, so as to achieve the purpose of precise implantation and meet the personalized implantation requirements.

[0004] Before the operation, the digital dynamic real-time navigation implant system obtains the alveolar bone and overall oral environment data of the patient through CBCT and oral scanning, etc. The imaging data and model data are imported into the dynamic navigation system. Through 3D printing technology, an implant guide plate is prepared, and the whole process of implant placement with restoration guidance is simulated. The surgical steps are carefully planned. During the operation, according to the surgical plan formulated before the operation, under the assistance of dynamic navigation, operations such as accurately guiding the step-by-step preparation of the hole are carried out. The position and movement trajectory of the surgical instrument will be displayed on the screen of the navigation system. The doctor can accurately operate according to the displayed information to ensure that the implant is implanted at the preset position, angle and depth. Due to the limitation of computing power, there will be a delay in the position of the implant handpiece displayed on the screen of the current dynamic navigation system. The doctor cannot directly observe the screen of the navigation system for surgery. Although the guiding holes for determining the drilling direction of the drill bit are set on the implant guide plate, the depth still depends on the doctor's control of the handpiece. Dental implant requires multiple drillings with different drill bits, including: positioning round drills, pioneer drills, reamers, etc. The large number of drillings and the screen display delay of the navigation system will both cause problems such as the doctor operating the implant handpiece to drill too deep. For this reason, the inventor proposes a personalized assistance system for oral implant. Summary of the Invention

[0005] The purpose of the present invention is to provide a personalized assistance system for oral implant to solve the problems raised in the background technology. The specific technical solutions are as follows:

[0006] To achieve the above object and other related objects, the present invention provides a personalized assistance system for oral implant, including: a data acquisition device, a computer processing system, a navigation and positioning device, a display device, an implant handpiece, an implant guide plate, and a guiding device.

The sliding rod slidably penetrates through the lower support part. The spring is arranged between the support piece and the lower support part. A stepped structure cooperating with the sliding rod is arranged on the outer peripheral surface of the upper support part. The stepped structure includes a reference table surface and a plurality of auxiliary table surfaces. The upper support part is arranged to be rotatable on the upper side surface of the head so that the reference table surface or any one of the auxiliary table surfaces rotates to the position pointed by the end of the sliding rod.

[0008] Preferably, a plurality of gaskets with the same thickness are arranged on the auxiliary tabletop.

[0009] Preferably, a thrust ball bearing is arranged on the lower side surface of the upper support portion.

[0010] Preferably, a plurality of downward limiting blocks are arranged around the upper support portion, and the plurality of limiting blocks are respectively arranged on the side surface of the machine head.

[0011] Preferably, the support connection portion is a clamping strip, the clamping strip is arranged on the lower support portion, a clamping groove corresponding to the clamping strip is formed on the upper support portion, and the clamping groove is of a strip-shaped structure.

[0012] Preferably, a bevel groove is arranged on one side of the clamping groove.

[0013] Preferably, a plurality of protrusions are arranged inside the clamping groove.

[0014] Preferably, the implant handpiece includes a handle, a handpiece logo plate, a machine head and a drill bit. The handpiece logo plate is arranged on the handle, the machine head is arranged at the end of the handle, and a replaceable drill bit is arranged on the machine head.

[0016] A personalized auxiliary system for oral implant provided by the present invention has the following beneficial effects:

[0017] By adding a guiding device and installing the guiding device on the machine head, an auxiliary tabletop corresponding to the stepped structure can be processed, and a reference tabletop lower than the auxiliary tabletop is set. When the sliding rod contacts the reference tabletop, the reference tabletop provides support for the implant handpiece. The doctor can turn his head to look at the display. After waiting for the system delay, check whether the gap between the drill bit and the drilling target depth conforms to the height difference between the reference tabletop and the auxiliary tabletop. After determining compliance, rotate the upper support portion to move the auxiliary tabletop corresponding to the drill bit above the sliding rod, continue to press down the implant handpiece to complete one drilling, then replace the drill bit on the machine head and execute the above steps. Finally, complete all drilling operations. It is convenient to use and will not cause the problem that the doctor drills too deep when operating the implant handpiece due to the delay generated by the existing navigation system. It is convenient to perform multiple drillings during the operation to ensure that the drilling depth meets the requirements. When there is an error in the depth, the corresponding thickness of the gasket can be increased or decreased according to the deviation value, and the adjustment can be made in time.

[0030] The computer processing system includes a computer host with computing power to process and analyze a large amount of three-dimensional image data and oral implant navigation software. It integrates, analyzes, and processes the data from the cone beam CT and the intraoral scan, reconstructs a three-dimensional model of the patient's oral cavity. Doctors can perform virtual planning of implant surgery in the software, including selecting the type and size of the implant, determining the implant position, angle, and depth, etc., and can simulate the surgical process, evaluate the surgical risks and effects, and construct the three-dimensional structure of the implant guide 200, which is printed out by a 3D printing device;

[0031] The navigation and positioning device includes a camera and a navigation marker board. The camera tracks the position and attitude of the implant handpiece 100 in real time by recognizing the navigation marker boards installed on the implant handpiece 100 and the implant guide 200;

[0032] The implant handpiece 100 is for the doctor's manual operation. The implant handpiece 100 includes a handle 110, a handpiece marker board 120, a head 130, and a drill bit 140. The handpiece marker board 120 is arranged on the handle 110. The head 130 is arranged at the end of the handle 110, and a replaceable drill bit 140 is arranged on the head 130;

[0033] The display device is a monitor, which is used to display the comparison information between the surgical instruments and the virtual planning path, as well as data such as the real-time position and angle of the implant, enabling the doctor to adjust the surgical operation in a timely manner;

[0034] The implant guide 200 includes a guide plate body 210. The guide plate body 210 is provided with positioning holes 211 and marking grooves 212. A guide tube 220 is inserted into the positioning holes 211, and the marking grooves 212 are used for the installation of the navigation marker board;

[0035] The guiding device 300 is arranged at the nose 130 of the implant handpiece 100. The guiding device 300 includes a lower support portion 310, an upper support portion 320, a support connection portion 330, and a guide plate connection portion 340. The lower support portion 310 is arranged on the lower side of the nose 130, and the upper support portion 320 is arranged on the upper side of the nose 130. The lower support portion 310 and the upper support portion 320 are detachably connected through the support connection portion 330 and are mounted on the nose 130 through the lower support portion 310, the upper support portion 320, and the support connection portion 330. The guide plate connection portion 340 is arranged below the lower support portion 310 and is used for connecting the guide cylinder 220. The guide plate connection portion 340 includes an outer sliding sleeve 341, a sliding rod 342, and a spring 343. The outer sliding sleeve 341 is slidably connected to the guide cylinder 220. A plurality of support pieces 344 extend outward from the outer peripheral surface of the outer sliding sleeve 341. The sliding rod 342 is arranged on the support pieces 344 and slidably penetrates through the lower support portion 310. The spring 343 is arranged between the support pieces 344 and the lower support portion 310. A stepped structure 321 that cooperates with the sliding rod 342 is arranged on the outer peripheral surface of the upper support portion 320. The stepped structure 321 includes a reference table surface 321a and a plurality of auxiliary table surfaces 321b. The upper support portion 320 can rotate on the upper side surface of the nose 130 so that the reference table surface 321a or any one of the auxiliary table surfaces 321b rotates to the position pointed by the end of the sliding rod 342. A plurality of gaskets 321c with the same thickness are arranged on the auxiliary table surface 321b.

[0036] Specifically, before the operation, the doctor first obtains the three-dimensional image data of the patient's oral and maxillofacial bones through cone-beam CT to provide detailed bone structure information, including bone density, bone mass, anatomical structure, etc., providing basic data for the planning of the implant surgery. The intraoral scanner is used to obtain the surface morphology data of the teeth, gums and other soft tissues in the patient's oral cavity and send it to the computer processing system. The data of cone-beam CT and intraoral scan are integrated, analyzed and processed to reconstruct the three-dimensional model of the patient's oral cavity. The doctor can perform virtual planning of the implant surgery in the software, including selecting the type and size of the implant, determining the implant position, angle and depth, etc., and can simulate the surgical process, evaluate the surgical risks and effects. Based on the implant position and angle, the three-dimensional structure of the implant guide plate 200 with the positioning holes 211 is constructed and printed out by a 3D printing device. The guide cylinder 220 is press-fitted into the positioning holes 211 of the implant guide plate 200. Then, the implant guide plate 200 is installed and fixed on the patient's teeth according to the pre-planned surgical plan, and the navigation marker plate is installed in the marker groove 212 of the implant guide plate 200. According to the pre-determined implant depth, the stepped structure 321 is processed. Since the upper support part 320 is always attached to the upper side surface of the nose 130 of the implant handpiece 100 under the action of the support connection part 330, the distance between the stepped structure 321 and the end of the drill bit 140 is fixed. Therefore, during the simulation of the operation, the distance of the downward movement of the drill bit 140, that is, the downward movement distance of the upper support part 320, can be determined. The outer sliding sleeve 341 is sleeved on the guide cylinder 220, and the drill bit 140 can only move along the axis direction of the guide cylinder 220. The length of the sliding rod 342 is fixed. Therefore, according to the downward movement requirements of different drill bits 140, the corresponding auxiliary table surface 321b is processed on the stepped structure 321, and a reference table surface 321a lower than the auxiliary table surface 321b is set. The lower support part 310 and the upper support part 320 are respectively placed on the lower side and the upper side of the nose 130, and the lower support part 310 and the upper support part 320 are firmly connected to the body by the support connection part 330. During the operation, first rotate the upper support part 320 to move the reference table surface 321a above the sliding rod 342, press down the implant handpiece 100, and use the drill bit 140 to drill. When the sliding rod 342 contacts the reference table surface 321a, the reference table surface 321a provides support for the implant handpiece 100. The doctor can turn his head to look at the display, and after waiting for the system delay, check whether the gap between the drill bit 140 and the drilling target depth meets the height difference between the reference table surface 321a and the auxiliary table surface 321b. After determining that it meets the requirements, rotate the upper support part 320 to move the auxiliary table surface 321b corresponding to the drill bit 140 above the sliding rod 342, continue to press down the implant handpiece 100 to complete one drilling, and then replace the drill bit 140 on the nose 130 and perform the above steps until all drilling operations are completed. When it does not meet the requirements, according to the deviation value, increase or decrease the gasket 321c with the corresponding thickness.The gasket 321c can be arranged on the auxiliary tabletop 321b in a bonding or magnetic attraction connection manner.

[0037] Furthermore, in order to facilitate the rotation of the upper support portion 320, a thrust ball bearing is provided on the lower side surface of the upper support portion 320. In order to prevent the upper support portion 320 from rotating deviantly, a plurality of downward limiting blocks 322 are provided on the periphery of the upper support portion 320. The plurality of limiting blocks 322 are respectively arranged on the side surface of the machine head 130 and are used to limit the upper support portion 320.

[0038] As an implementation manner of the present invention, the support connection portion 330 is a card strip. The card strip is arranged on the lower support portion 310. A card slot 323 corresponding to the card strip is opened on the upper support portion 320. The card slot 323 has a long strip-shaped structure so that the end portion of the card strip can slide in the card slot 323. A groove 323a is provided on one side of the card slot 323. By rotating the upper support portion 320, the end portion of the card strip can be made to slide out of the card slot 323 from the groove 323a, realizing the detachment from the upper support portion 320. A plurality of protrusions 324 are provided inside the card slot 323. The protrusions 324 are used to limit the end portion of the card strip so as to limit the position of the card strip in the card slot 323, making the relative position of the sliding rod 342 and the stepped structure 321 correspond and not shift.

[0039] Finally, it should be noted that the above implementation manners are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred implementation manners, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention.
