Background
The zygomatic grafting is a tooth implantation repair method adopted in tooth implantation repair, wherein the maxillary bone mass is seriously damaged or atrophied, and a patient does not want to accept bone augmentation operations such as bone implantation, bone distraction and the like. The cheekbone-passing implantation means that a dental implant is implanted into cheekbones, and 2-4 conventional dental implants are implanted into an anterior dental area by means of a compact bone block of the cheekbones so as to jointly complete the repair of maxillary dentition. The length of the cheekbone implant is generally 30.0-60 mm. The zygomatic implant enters the maxillary sinus from the dental ridge and enters the zygomatic bone through the mucosa outside or the outer bone wall of the maxillary sinus, and most of the middle part of the implant is exposed outside the mucosa of the maxillary sinus and under soft tissues. The length of the cheekbone implant is closely related to the jaw-face anatomical structure of the patient. Generally, the zygomatic implant is implanted at the atrophic alveolar ridge palatal side of the posterior dental area, the cortical bone of the alveolar bone of a patient with severe bone atrophy is less, and after the implant is repaired, the cervical bone absorption of the zygomatic implant is easy to occur, and finally the cervical thread of the implant is exposed, so that complications such as peri-implant inflammation, oronasal maxillary sinus fistula and the like occur. Researches show that the existing clinically used full-thread coarse surface cheek implant has the problems of peri-implantitis, maxillary sinus stimulation inflammation, aseptic inflammation of cheek bone and cheek face and other complications, and recently, scholars at home and abroad propose improved operative formulas to reduce the generation of related complications, and meanwhile, new operative formulas urgently need to carry out various forms of improved design on the cheek implant according with clinical needs.

The included angle between the working surface of the thread in the alveolar bone thread part 22 and the radial direction of the implant transition part 2 is 5-20 degrees; 5 degrees to 10 degrees; 10 degrees to 15 degrees; or 15-20 degrees, etc. The design has the advantages that the contact area of the implant and the alveolar bone is increased, the stress of the cervical and palatal bone plates can be effectively dispersed, and the bone absorption is reduced.
In the cheekbone implant provided by embodiments of the present application, as shown in fig. 1, in one particular embodiment, the implant neck 3 is a smooth surface machined without threads. Therefore, after the dental implant is repaired, if the alveolar bone at the top of the alveolar ridge is absorbed, the peri-implantitis can be effectively avoided.
As shown in FIG. 2, in another specific embodiment, different from the first embodiment, the implant neck 3 includes a rough surface, and the roughness of the rough surface can be 0.1-1 um; 0.1-0.3 um; 0.3-0.5 um; 0.5-0.8 um; 0.8-1 um; 0.1-0.6 um; or 0.7-1 um. Since the implant neck 3 is located at the alveolar ridge portion, osseointegration and surface cleaning are facilitated after low-roughness surface treatment.
In the embodiment of the present application, one end of the implant neck 3 away from the implant transition portion 2 is a hollow inner hexagonal structure, when the implant is packaged from a factory, the implant neck 3 is provided with an implanted carrying body, the carrying body is an outer hexagonal structure, and the outer hexagonal structure of the carrying body is matched with the inner hexagonal structure of the implant neck 3. The carrying body is made of disposable medical stainless steel, and the tail part of the carrying body is provided with a covering screw. Because the implant neck 3 is a hollow structure, the implant and the carrying body are matched for use for convenient installation and carrying, and the carrying body can be taken down after the implant is installed.

Clinically, according to the specific conditions of a patient, an implant with a proper length is selected, and the implant is implanted after the implant pit is prepared. The specific clinical use of the zygomatic implant of the application is as follows:
1. according to the cheekbone planting process, anaesthetizing, turning a valve, windowing a maxillary sinus, carrying out preoperative design and ZAGA anatomical classification, completing fixed point, positioning and three-dimensional direction determination, completing drilling a preparation hole by using a cheekbone planting reamer, washing bone chips, soft tissue chips and the like in a pore canal;
2. zygomatic implant implantation: (1) accurately measuring the depth of an implant pore channel by using a cheekbone implant depth measuring ruler, and selecting a cheekbone implant with a proper length; (2) confirming the length of the implant, opening the external package of the zygomatic implant, taking out and carefully opening the sterile plastic package, and carefully pouring the zygomatic implant with the sterile inner-layer package on a sterile operating table to avoid contact with the sterile inner package and falling and pollution of the inner-layer package; (3) fully exposing the operation area in the mouth, stabilizing the opening position of a patient, holding an implant carrier by an operator, removing the aseptic titanium tube package, carefully screwing the cheekbone-passing implant into the cheekbone-upper jaw base positioning hole through the finger of the maxillary sinus area from the implantation site, completely implanting the cheekbone-passing implant by using a manual implantation wrench, and adjusting the inner hexagonal plane to be consistent with the buccal surface; the oral cavity is exposed to heal by installing a sealing screw or installing a composite abutment and a healing cap, and the oral cavity can be repaired by matching with other implants under the condition of better initial stability; (4) note that: when the implant is implanted, if the thread section of the implant is implanted into the bone less than 1/3, namely the torsion is larger, the implant is recommended to be withdrawn from the sterile titanium sleeve, and the implant can be implanted again after a part of preparation is carried out according to the condition of the bone; the implantation torque is controlled to be about 55Ncm, and excessive torque implantation is not recommended.
3. And finishing other work flows of planting, sewing and the like according to the zygomatic planting flow.
In summary, the cheekbone implant and the oral implant provided by the embodiment of the application have the following advantages:
1. guide portion 11 is the smooth guide area of minor diameter, is the smooth unthreaded surface of machining, avoids guide portion 11 to cause the emergence of inflammatory reaction such as skin cheek fistula.
2. The mounting part 12 is in a conical design, the zygomatic bone implanted thread section comprises two sections of threads, and the large-pitch self-tapping thread design is convenient for implantation, reduces bone damage during implantation and obtains better initial stability.
3. The implant transition part 2 includes the connected maxillary sinus smooth surface part 21 and the alveolar bone screw part 22, and the maxillary sinus smooth surface part 21 avoids the maxillary sinus membrane irritative wound, protects the integrity thereof, and can effectively avoid various biological complications. The alveolar bone screw part 22 is located at an alveolar bone part, and can be osseointegrated well with the alveolar bone.
4. The implant neck 3 positioned in the alveolar ridge section during installation is a thread-free and low-roughness surface, so that osseointegration is facilitated, and the occurrence of biological complications of the implant neck is reduced.
In conclusion, the present application effectively overcomes various disadvantages of the prior art and has high industrial utilization value.
