[0028] Example 1

[0029] Please see the attached Figure 1-3 The purpose of this embodiment is to provide a 3D printed implant guide, including: an implant guide body 1, the implant guide body 1 is sleeved on the tooth, the implant guide body 1 is connected to a guide member through two support rods 2; the guide member is a guide sleeve, the opening of the guide sleeve is arranged toward the implant guide body 1, and the bottom of the guide sleeve is a fitting surface; a plurality of hollow grooves are provided on the side wall of the guide sleeve.

[0030] In this embodiment, the guide sleeve is a first guide sleeve 3. The sidewall of the first guide sleeve 31 in the first guide sleeve 3 is provided with a plurality of first hollow grooves 33. The plurality of first hollow grooves 33 can reduce the use of 3D printing materials. In a preferred embodiment, the implant guide body 1 can also be provided with a plurality of hollow grooves to further reduce the use of 3D printing materials. The bottom of the first guide sleeve 31 is a first fitting surface 32, which is used to fit the surface of the maxillary bone. The maxillary bone is not a bone surface, but rather the outer surface of the soft tissue of the maxillary bone in the oral tissue. The first guide sleeve 31 is provided with a first curved guide inner wall 311. The first guide sleeve 31 is also provided with a guide side ring 312. The inner surface of the guide side ring 312 forms a limiting annular surface with the first curved guide inner wall 311. The bottom surface of the guide side ring 312 is located higher than the highest point of the first fitting surface 32. The first opening 313 of the first guide sleeve 31 extends upward from the top surface of the guide side ring 312. In this embodiment, based on the CT scan data of the teeth and jaws in the oral cavity, the implant guide body 1, the support rods and the guide parts are 3D printed, except for the implant mobile phone 5.

[0031] The implantation system using the implantation nail guide plate includes: an implantation mobile phone 5, the implantation mobile phone 5 includes a handle 51, and the handle 51 is connected to a connecting rod section 52 and a guide section 53 in sequence.

[0032] It can be seen from the above structure that the inner side surface of the guide side ring 312 and the first arc-shaped guide inner wall 311 form a limiting annular surface. When using the implantation mobile phone 5 to implant the implant nail, the guide section 53 fits the inner side surface of the guide side ring 312 and the first arc-shaped guide inner wall 311 to implant the implant nail. The inner side surface of the guide side ring 312 and the first arc-shaped guide inner wall 311 jointly guide the guide section 53. After the implant nail is implanted, the guide section 53 moves upward and can be removed from the first opening 313, which is convenient to use.

[0033] It should be noted that some existing guide sleeves use a completely open opening, which provides poor guidance and can easily cause the implanted handpiece to shift. Completely enclosed sleeves can make it difficult to remove the implanted handpiece, making it inconvenient to use. The guide plate of this application overcomes these shortcomings by providing both a closed guide portion and an opening.

[0034] Example 2

[0035] Please continue to refer to the attached Figure 4-8 The purpose of this embodiment is to provide a 3D printed implant guide, including: an implant guide body 1, the implant guide body 1 is sleeved on the tooth, the implant guide body 1 is connected to a guide member through two support rods 2; the guide member is a guide sleeve, the opening of the guide sleeve is arranged toward the implant guide body 1, and the bottom of the guide sleeve is a fitting surface; a plurality of hollow grooves are provided on the side wall of the guide sleeve.

[0036] In this embodiment, the guide sleeve is a second guide sleeve 4. The sidewall of the second guide sleeve 41 within the second guide sleeve 4 is provided with a plurality of second hollow grooves 43. These multiple second hollow grooves 43 can reduce the amount of 3D printing material used. In a preferred embodiment, the implant guide body 1 can also be provided with multiple hollow grooves to further reduce the amount of 3D printing material used. The bottom of the second guide sleeve 41 is a second fitting surface 42, which is designed to fit the surface of the maxillary bone. The maxillary bone is not a bone surface, but rather the outer surface of the soft tissue of the maxillary bone in the oral cavity. The second guide sleeve 41 is also provided with a second, opposing, curved guide inner wall 411 and a second opening 412.

[0037] Specifically, the second guide sleeve 41 is further provided with a first guide assembly 44 and a second guide assembly 45 above and below. The first guide assembly 44 and the second guide assembly 45 have the same structure. Each of the first guide assembly 44 and the second guide assembly 45 includes a screw 442 disposed on the outer wall of the second guide sleeve 41. Each screw 442 is screwed onto a nut 441. The two sides of each nut 441 are connected to the two ends of a steel wire 443. Each steel wire 443 passes through a pair of through holes 413 in the second guide sleeve 41.

[0038] The implantation system using the implantation nail guide plate includes: an implantation mobile phone 5, the implantation mobile phone 5 includes a handle 51, and the handle 51 is connected to a connecting rod section 52 and a guide section 53 in sequence.

[0039] From the above structure, it can be seen that by rotating the nut 441, the length of the steel wire 443 in the second opening 412 of the second guide sleeve 41 is adjusted so that the inner diameter of the limiting portion composed of the steel wire 443 and the second curved guide inner wall 411 is equal to the outer diameter of the guide segment 53. The guide segment 53 fits the inner side of the steel wire 443 and the second curved guide inner wall 411. The inner side of the steel wire 443 and the second curved guide inner wall 411 jointly guide the guide segment 53. After the implant nail is implanted, the guide segment 53 moves upward and out, which is easy to use.

[0040] Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model should be included in the scope of protection of this utility model.
