Description

Technical Field

[0001] The utility model relates to the technical field of dental implant marking, and particularly relates to a positioning and marking tooling for dental implants. Background Art

[0002] It refers to a tooth defect restoration method that supports and retains the upper dental prosthesis based on the lower structure implanted in the bone tissue. It includes two parts: the lower supporting implant (dental implant) and the upper dental prosthesis (dental prosthesis, implant - supported). It uses artificial materials (such as metals, ceramics, etc.) to make implants (generally in a shape similar to the root of a tooth), which are implanted into the tissue (usually the upper and lower jaws) through surgical methods and obtain firm retention and support from the bone tissue, and the upper dental prosthesis is connected and supported through special devices and methods. Since the implant is directly implanted inside the gum, it is sometimes directly called a dental implant. Dental implants can achieve a restoration effect very similar to that of natural teeth in terms of function, structure, and aesthetic effect, and have become the preferred restoration method for more and more tooth - missing patients.

[0003] There are various different shapes of dental implants. Usually, laser marking is used to mark different dental implants for distinction. Laser marking is a marking method that uses a laser with a high energy density to locally irradiate the workpiece, causing the surface material to vaporize or undergo a chemical reaction with color change, thereby leaving a permanent mark. Laser marking can produce various characters, symbols, patterns, etc. The character size can range from millimeters to micrometers, which has special significance for product anti - counterfeiting.

[0004] The marking positions of dental implants with different shapes may be different. Some dental implants are marked on their sides, and some are marked on the end face at one end. Even some dental implants are marked at multiple circumferential positions along their sides during marking. In the related art, dental implants are often fixed on the workbench with putty, and then the laser marking device is aligned with the marking part on the side of the dental implant. The alignment operations include adjusting the position of the lens (so that the lens is perpendicular to the current marking surface of the dental implant) and adjusting the focal length (so that the laser can be focused on the current marking surface), etc. Then, marking can be carried out. After marking the current marking part, the position of the dental implant is adjusted again, and the laser marking device is aligned with the marking part of the dental implant again, so as to mark multiple marking parts of the dental implant. In the above - mentioned situation, the lens of the laser marking device needs to be aligned with the marking part of the dental implant multiple times, resulting in a relatively cumbersome marking process for dental implants. Content of the Utility Model

[0005] The purpose of the present utility model is to provide a positioning and marking tooling for dental implants, so as to solve the problem that the process of marking multiple parts on the side of dental implants is rather cumbersome.

[0006] The present utility model is realized through the following technical solutions:

[0007] A positioning and marking tooling for dental implants includes a workbench. Above the workbench, a three-jaw chuck is rotatably arranged, and the rotation axis of the three-jaw chuck is parallel to the working surface of the workbench; a vacuum suction sleeve is clamped on the three-jaw chuck, and the central axis of the vacuum suction sleeve is parallel to the rotation axis of the three-jaw chuck. One end of the vacuum suction sleeve close to the three-jaw chuck is a vacuum chamber, and an installation hole is opened at the other end inside. The end of the vacuum chamber away from the installation hole is sealed. The installation hole is larger than the inner diameter of the vacuum chamber. A sudden expansion step is provided between the vacuum chamber and the installation hole. A positioning post is arranged in the installation hole. One end of the positioning post located in the installation hole is used to abut against the sudden expansion step. An air suction hole is opened on the side wall of the vacuum chamber. A positioning groove is opened on the end face of the positioning post located outside the installation hole. The positioning groove is used to install the dental implant, and a plurality of marking holes are opened on the side wall of the positioning groove along the circumferential direction; a through hole is opened inside the positioning post, and one end of the through hole is communicated with the vacuum chamber, and the other end extends to the corresponding end face of the dental implant after passing through the positioning post.

[0008] Furthermore, the cross-section of the installation hole is circular, and the positioning post is in sliding fit with the inner hole wall of the installation hole. A through threaded hole is opened on the side wall of the installation hole, and a tightening bolt is threadedly connected inside the threaded hole. The extension line of the end of the tightening bolt located inside the installation hole intersects with the central axis of the installation hole; a tightening plane is provided on the side wall of the positioning post, and the tightening plane is parallel to the central axis of the installation hole. The tightening bolt is used to abut against the middle of the tightening plane.

[0009] Furthermore, a positioning plane is provided on any one of the jaws of the three-jaw chuck. A fitting plane is opened on the outer wall of the vacuum suction sleeve, and the fitting plane is parallel to the central axis of the inner hole of the vacuum suction sleeve. The positioning plane is used to fit with the fitting plane.

[0010] Further, a sliding groove is formed in the upper surface of the workbench along the rotation axis direction of the three-jaw chuck, and a fixing plate is placed on the workbench; a fixing table is arranged on the fixing plate, and a stepped structure is arranged on the fixing table. The stepped structure includes a plurality of inclined steps with inclined upper surfaces and at least one horizontal step with a horizontal upper surface. The inclination angles of the upper surfaces of the plurality of inclined steps on the stepped structure gradually decrease along the climbing direction; a fixing block is arranged on each of the inclined steps and the horizontal step, and a fixing hole is formed in each fixing block. A thread is formed inside the fixing hole, and each fixing hole is used for threadedly connecting a corresponding dental implant. One end face of the dental implant away from the fixing block inside each fixing hole is parallel to the upper surface of the fixing plate.

[0011] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0012] In the utility model, when the marking part is located on the side surface of the dental implant and there are many marking parts, it is more convenient to use the marking tooling of this scheme; for the same-shaped dental implants mentioned above, first clamp the vacuum suction sleeve in the middle of the three-jaw chuck, and connect the suction pipe of the vacuum device to the suction hole of the vacuum suction sleeve; then install one end of the dental implant to be marked in the positioning groove of the positioning post, so that a plurality of marking parts on the side surface of the dental implant are all located at the corresponding marking holes, and then install the positioning post inside the vacuum suction sleeve so that the positioning post abuts against the protruding and expanding step, and then start the vacuum device. The vacuum chamber of the vacuum suction sleeve is sucked into a vacuum through the vacuum device, so that the positioning post is tightly adsorbed in the installation hole. Since one end of the through hole is communicated with the vacuum chamber and the other end extends to the corresponding end face of the dental implant after passing through the positioning post, the inside of the through hole also becomes a vacuum, so that the dental implant is also tightly adsorbed in the positioning groove of the positioning post. At this time, the fixation of the dental implant is realized; first, align one marking surface of the dental implant with the lens of the laser marking device, and record the angle information of the three-jaw chuck at this time. The three-jaw chuck is connected to the servo motor through the main shaft, and the angle information of the three-jaw chuck can be determined by the rotation angle of the servo motor. Then rotate the three-jaw chuck so that the lens of the laser marking device is aligned with the next marking surface, and record the angle information of the three-jaw chuck at this time. Repeat the above steps to record the angle information of the three-jaw chuck corresponding to all marking surfaces of the same dental implant in sequence; and during the specific marking, only the first marking surface needs to be positioned, and the remaining other marking surfaces can be rotated by a pre-determined angle by the servo motor driving the three-jaw chuck, so as to quickly position the other marking surfaces, and then the marking operation of the above dental implant can be carried out conveniently and quickly.
