Technical Field

[0001] The utility model relates to the technical field of dental surgical tools, in particular to a digital combined guide plate for full-mouth implantation. Background Art

[0002] As my country's population ages further, the number of edentulous patients will increase accordingly. Traditional full dentures are unsatisfactory in restoring chewing function. Due to severe absorption of alveolar bone and changes in the position and morphology of soft tissues leading to changes in the neutral zone, full dentures can cause pain, poor retention, dysphonia, nausea and other problems during use. With the development of implant restoration technology, implant-supported full denture restoration for edentulous jaws has become another treatment option for edentulous patients, providing a solution for fully restoring the chewing function of edentulous jaw patients and improving their quality of life. Computer-assisted implant surgery, driven by the development of digital technology, has been widely used in the field of edentulous implant restoration due to its high predictability and accuracy. In the clinical operation of computer-assisted implant surgery, implant guides provide surgeons with a way to implant implants in the ideal position with high accuracy.

[0003] Currently, related technologies for digital guides for full-mouth implants, such as CN116919636A, CN116570393A, CN114366359A, CN114081649A, etc., all disclose combined digital guides, which complete the implantation of the implant through a combined method. However, during the operation, there is no fixing device on the gums. Due to the yieldability of the gums and the swelling of the gums caused by local anesthesia, the accuracy of the guide installation position is easily reduced. In addition, the gums after flap treatment block the field of view of the surgical area, and the needle may damage the gums when preparing the implant hole.

[0004] Therefore, people are in urgent need of a full-mouth implant digital combination guide that can improve the guide installation accuracy, gum protection and surgical area exposure by fixing the gums. Summary of the Invention

[0005] The purpose of this utility model is to provide a digital combination guide for full-mouth implants to solve the problems existing in the above-mentioned prior art. By reserving a gap, the gingiva after flap opening is fixed, and the installation accuracy of the guide is improved, the protection effect on the gingiva and the exposure effect of the surgical area are improved.

By reserving a gap, the gingiva behind the flap is fixed, and the installation accuracy of the guide is improved, the protection effect on the gingiva and the exposure effect of the surgical area are improved.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0032] Please refer to Figures 1 to 6 As shown, a full-mouth implant digital combination guide is provided, including a retention nail guide fixed on the alveolar bone by a fixing nail and a guide plate 2 for implantation. The implantation guide plate 2 is detachably connected to the retention nail guide plate. The fixing nail guide plate 1 is annular, and the annular structure matches the surrounding structure of the maxillary or mandibular teeth. The fixing nail guide plate 1 is arranged around the alveolar bone. There is a reserved gap 7 for accommodating the gums between the implantation guide plate 2 and the inner edge of the fixing nail guide plate 1. The implantation guide plate 2 is provided with an implant guide hole 5 for guiding the implant to enter corresponding to the desired implantation position. The fixing nail guide plate 1 is provided with a fixing nail hole 6 for the fixing nail to pass through. During the operation, due to the presence of the reserved gap 7, the gingiva after the flap is turned can be placed in the reserved gap 7 to complete the fixation of the gingiva. After the gingiva is fixed, the guide plates on both sides will have a certain restrictive effect on the gingiva, so that it will not hinder the installation of the implant guide 2, thereby improving the accuracy of the guide installation. Moreover, the gingiva remains in a shape turned outward to the circumferential side, and will not block the surgical area, thereby improving the exposure effect of the surgical area and making the surgical field clearer. At the same time, it reduces the possibility that the needle may damage the gingiva when preparing the implant hole. During the operation, the cooling saline can also accurately reach the drilling site to cool it without the obstruction of the gingiva, which is beneficial to improving the success rate of the operation. The retaining nail guide and the implant guide 2 can be a 3D-printed resin structure or a 3D-printed metal structure.

[0033] In this embodiment, the detachable connection method of the fixed nail guide 1 and the planting guide 2 is: a plurality of slots 8 are provided around the fixed nail guide 1, and a plurality of first pins 9 are provided at positions corresponding to the slots 8 on the planting guide 2. The slots 8 match the first pins 9, and the detachable connection is completed by plugging. In other embodiments, the connection method of the fixed nail guide 1 and the planting guide 2 can be a groove type, a snap type or a magnetic type. When the groove type is connected, matching vertical grooves and vertical slide rails are respectively provided on the opposite wall surfaces of the fixed nail guide 1 and the planting guide 2, and the vertical slide rails are slidably inserted in the vertical grooves. When the snap type is connected, a protrusion is provided on the outer periphery of the fixed nail guide 1, and a deformable hook body is provided on the planting guide 2 for hooking the protrusion; when the magnetic type is connected, lateral protrusions are provided on the fixed nail guide 1 and the planting guide 2, and the lateral protrusions of the two guides are opposite to each other up and down, and magnets are provided on the lateral protrusions to complete magnetic attraction.

[0034] The full-mouth implant digital combination guide also includes a positioning guide 3, which is detachably connected to the fixed nail guide 1. The end of the positioning guide 3 close to the teeth is provided with a positioning groove 11 corresponding to and matching the remaining teeth (teeth retained for positioning during positioning). The positioning groove 11 is formed by the plate surface at the specified position of the positioning guide 3 protruding in the direction away from the teeth, and the shape of the protruding outer surface matches the remaining teeth. The setting of the positioning guide 3 enables the fixed nail guide 1 to be positioned after being connected to the positioning guide 3. The positioning function of the positioning groove 11 of the positioning guide 3 and the remaining teeth is relied upon to complete the positioning of the fixed nail guide 1, thereby improving the convenience of positioning. Local anesthesia can be performed after the positioning of the fixed nail guide 1 is completed to prevent local anesthesia from being performed before the guide is installed, and gum swelling from affecting the accuracy of guide positioning.

[0035] The inner bottom wall of the positioning slot 11 that matches the remaining tooth matches the end surface of the remaining tooth away from the alveolar bone, and the size of the slot should ensure that the remaining tooth can enter the positioning slot 11.

[0036] In this embodiment, the detachable connection method of the fixed nail guide 1 and the positioning guide 3 is: a plurality of slots 8 are provided around the fixed nail guide 1, and a plurality of second pins 10 are provided at positions corresponding to the slots 8 on the positioning guide 3. The slots 8 match the second pins 10, and the detachable connection is completed by plugging; in other embodiments, the connection method of the fixed nail guide 1 and the positioning guide 3 can be selected from the groove type, snap-on type or magnetic type connection between the above-mentioned fixed nail guide 1 and the planting guide 2.

[0037] In this embodiment, the positioning guide 3 is made of translucent resin and is formed by 3D printing. The translucent property allows for observation of whether the positioning slot 11 fits the remaining teeth after the positioning guide 3 is installed, making it easier to determine whether the positioning is complete.

[0038] The full-mouth implant digital combination guide also includes a temporary dental restoration guide 4. The end surface of the temporary dental restoration guide 4 away from the alveolar bone is a protruding structure simulating a tooth. After the implant is implanted, the patient's chewing function can be restored through the temporary dental restoration guide 4. Since the implant has a protruding base, an abutment guide hole 12 is provided at the position of the temporary dental restoration guide 4 corresponding to the abutment of the implant.

[0039] In order to improve the installation stability of the temporary dental restoration guide plate 4, the abutment guide hole 12 is matched with the abutment, and the abutment is inserted into the abutment guide hole 12 to complete the limitation of the temporary dental restoration guide plate 4.

[0040] The temporary dental restoration guide plate 4 is made of temporary crown material, such as polycarbonate, methyl methacrylate plastic, acrylic resin, etc., which can be formed by 3D printing, or made of resin material and processed by CAD / CAM.

[0041] The fixing nail guide plate 1 is provided with an osteotomy plane 13 for guiding the trimming of the alveolar bone. The osteotomy plane 13 can be a straight plane, an arc surface or an irregular curved surface.

[0042] During actual use, the positioning pin guide is first connected to the positioning guide 3, and the positioning groove 11 of the positioning guide 3 is matched with the remaining teeth to complete the positioning. After the positioning is completed, local anesthesia is performed, and after local anesthesia, the fixing pin guide 1 is fixed to the alveolar bone with a fixing pin; the positioning guide 3 is removed, the gingiva is opened, and the implant guide 2 is installed.
