New description: , [New technical field] The author of this case is related to an artificial implant with thick and thin threads, especially one that facilitates the screwing, improves the grip after bone hyperplasia, and has Helps to organize the structure of the implant and the structure of the implant to prevent the risk of bacterial infection. [Prior Art] Old-fashioned dentures use existing human teeth and gums to bridge the way # fixed dentures, but in order to cooperate with the installation of dentures, it is often necessary to perform destructive surgery on adjacent healthy teeth. This method has gradually been eliminated by the industry. . The new type of artificial implant has been used in oral therapy for many years, and the success rate of implants has been greatly improved due to the improvement of materials and the improvement of implant technology. The so-called artificial implants mainly include artificial implants. In the three parts of the abutment and the crown, the implant system can be implanted into the humerus of the affected part of the oral cavity to replace the extracted root. The implant and the abutment must be designed to be combined with the locking structure. The fixed crown on the table is a series of artificial substitutes, the purpose of which is to replace the lost teeth. Referring to the first figure, the conventional implant 10 is a conical cylinder, and the outer peripheral surface of the lower end edge is provided with an external thread 11 . Generally, the external thread 11 is equidistant and contoured. The upper end surface of the implant 10 is recessed with a coupling hole 12, which is a blind hole having an internal thread, which can be screwed and fixed to the support table 13, and the support 13 can be fixedly coupled to the crown 14. When the dental implanting operation is performed according to the above-mentioned conventional structure, a dental hole is first drilled on the tibia, and then the lower end edge of the implant 10 is screwed into the dental hole by the external thread 11, so that the implant 10 is buried in the tibia and Only the bonding hole 12 is exposed for the 3 M43Q963 solid support abutment 13 and the crown 14; after the regenerative regeneration of the osteoblast, the bone tissue is proliferated into the screw gap of the external thread 11, and then covered The entire implant 10 is ordered to firmly bind the implant to the tibia. Since the external thread 11 of the conventional implant 10 is of an equidistant and contoured thread design, although the bone tissue is proliferated and can be closely adhered to the outer surface of the implant 10, the shape of the external thread 11 which is only sinful can not be effectively expressed. The grasping force between the implant 1 and the skeletal tissue, in other words, the known implant 丨〇 structure may cause the implant 10 to be easily loosened, not only the implant 1 can not be loaded, and the crown 14 attached thereto It is also difficult to maintain normal chewing ability. It can be seen that the above-mentioned conventional implant 10 still has a defect, which is not necessary for a good design and improvement. [New content] The purpose of the creation of this case is to improve the problem that the artificial implants can not effectively grasp the grasping force only by the consistent external thread shape; thereby providing a kind of facilitating the susceptibility of the snail and improving the bone hyperplasia. Post-grip force and implant structure that contributes to the tightness of the tissue and the risk of bacterial infection. In order to achieve the purpose, the present invention comprises: the implant, the implant is a conical cylinder, the lower end edge is a first screwing zone, and the upper edge is a second screwing zone, the first screwing zone and the second screwing zone The screwing zone has a thread, and the thread pitch of the first-screwing zone is wider. The pitch of the screw-to-feed distance is pure, and the pitch of the H-zone is narrower, and the distance from the valley to the peak is lower. ...", thereby, when the implant is screwed into the tooth hole, the first screwing region is screwed into the deeper bone. The squeezable thread increases the density of the bone, and also contributes to the snail by the design of the thread. The ease of human beings and the grip of the bones after the promotion of bone hyperplasia; and the 4th M430963: ^ screwing position (four) bones in the upper layer position 'the design of the thread is to help the tissue to seal the tightness, so that the wound damage is less The recovery is faster, and at the same time, it can prevent and reduce the risk of bacterial infection. [Embodiment] The technical content, features and effects of the present invention are described in detail below with reference to the preferred embodiments of the reference drawings. In addition, it is necessary to specifically describe the present invention before it is described in detail, and the drawings are illustrative of the basic structure of the present invention, and thus only the structures or elements related to the present invention are shown in the drawings. And the structural shape, size, ratio, or number of components shown, etc., is an optional design and will be described first. Please refer to the second figure for the specific embodiment of the present invention. And the cross-sectional structural diagram of the specific embodiment of the present invention is shown in the third figure. The present invention is an implant 2〇. The implant 2 is a conical cylinder whose top end surface is a polishing platform. The upper recess is provided with a coupling hole 21, and the binding hole 21 is a blind hole having an internal thread 211; the lower end edge of the implant 20 is a first screwing area 22, and the upper end edge is a second screwing area 23, the first screw The joint 22 and the second screwing zone 23 each have a thread 22 231, and the thread 221 of the first screwing zone 22 has a double crepe design with a wider pitch, and the thread 231 of the second screwing zone 23 is four inches. The micro-tight thread design of the grain has a narrow pitch, and the spiral valley to the screw peak distance of the ridge pattern 221 of the first screwing region 22 is high, and the spiral valley of the thread 231 of the second screwing region 23 has a spiral peak distance. Lower, the end of the first screwing zone 22 is a circular arc designer. According to the structure of the implant 20 of the above specific embodiment, the lower end edge of the implant 20 is provided with one or more cutting grooves 24, preferably The 'cut 5 M43Q963 grooved groove 24 is designed for three self-tapping spiral cutting grooves, and each is placed at the lower end of the implant 2 at an angle of 12 degrees. The cutting groove 24 has a sharp cut edge to enable self-tapping ability when the implant 20 is screwed. According to the implant 2〇 structure of the above specific embodiment, the polishing platform design of the top surface of the implant 2〇 The bottom edge of the recessed coupling hole 21 has an internal thread 211, and a tapered hole 212 is provided above the internal thread 211 to the top end surface of the implant 20. Preferably, the cone The hole 212 has a taper angle of about 22 degrees; the design of the joint hole 21 allows the abutment to be more tightly coupled to the plant body 20, and has a situation of preventing leakage and looseness. The thread 221 of the zone 22 is of double thread design, exhibiting a surface area of about 15% in a butterfly arc shape, reducing local stress concentration. The thread surface of the thread 221 is about 20 degrees, and the upper surface is about 14.5 degrees. Similar to ACME35. The thread shape can increase the BIC (Bone-to-implant contact), the torsion force and the bearing capacity. The double-threaded lead has a forward lead of about 1.8 legs, which makes it possible to implant the bone more quickly. It is easy to change the implantation angle at the time of implantation, and the tapered shaft of the first screwing region 22 and the second screwing region 23 are double-joined to effectively expand the bone ridge, make the bone denser, and can The bite force of the implant is effectively transmitted to the sponge bone, avoiding the excessive concentration of the occlusal stress on the alveolar bone 'to help the stability of the implant and bone integration. The thread 231 of the second screwing zone 23 is a four-thread design, the pitch is 〇. 45 dirty, and has a deeper fine thread than a general implant (about 2525 mm), and has sufficient bone volume storage space. The micro-tight thread design of the thread 231 increases the surface area and relatively increases the stability of the bone at the beginning of the implant. The cutting groove 24 of the lower edge of the implant 20 is designed by three self-tapping spiral cutting grooves, and in addition to improving the self-tapping ability, the 6 M430963 for the bone can be reduced. Destruction prevents the occurrence of skewing and reversal after implantation, and reduces the coefficient of friction between the bone and the bone, thereby reducing the chance of bone necrosis. Furthermore, the circular arc design at the end of the first screwing region 22 prevents damage to the superior sinus and the sacral neural tube structure during surgery. Referring to the fourth embodiment, by the structure of the implant 2.0, an aperture can be drilled on the tibia, and then the thread 221 of the first screwing region 22 of the implant 20 and the thread of the second screwing region 23 can be utilized. 231 is screwed into the dental hole, the implant 20 is embedded in the tibia and the bonding hole 21 is exposed to be fixed by the abutment 30, and the tooth Φ 訄 40 is fixed by the abutment 30, and the recovery and regeneration of the bone cell are repeated. The bone tissue is proliferated into the gap between the thread 221 of the first screwing region 22 of the implant 20 and the thread 231 of the second screwing region 23, thereby covering the entire implant 2〇, so that the implant 2 is stable. Combined with the tibia. Therefore, since the lower end edge of the implant 20 is provided with a cutting groove 24, the cutting groove 24 has a sharp cut edge, so that the implant 2 can be screwed into the tooth hole without the tapping process, and the valley is easy to self-tapping. . Moreover, since the pitch of the snail 221 of the first screwing region 22 is wider, the distance from the snail valley to the snail peak is higher, and the pitch of the thread 231 of the second screwing region 23 is narrower, and the distance from the snail valley to the snail peak is higher. Low, therefore, when the implant 20 is screwed into the tooth hole, the tapered first screwing region 22 is screwed into the deeper tibia, the squeezable thread increases the bone density of the tibia, and the thread 221 is designed to have a wider pitch, which helps The ease of screwing, the higher distance of the spiral valley to the screw peak of the thread 221 is to help improve the grasping force after the bone hyperplasia; and the second screwing area 23 is located at the upper bone position of the bone, the second screwing area The thread 231 of 23 is designed with a narrow pitch and a low distance from the snail valley to the snail peak. It helps the tissue to be sealed tightly, making the wound less damaged and recovering faster. It also prevents and reduces the bacterial sensation. 7 M430963 Risk of dyeing. Therefore, the surgeon can use the surgical technique to implant the implant 20 into the oral cavity of the patient, and after the osseointegration between the bone cells, the tibia and the implant 20 are tightly combined, in particular, the implant 20 is first snail. The thread 22, 231 of the joint region 22 and the second screwing region 23 are designed to ensure better effect of the implant body 20 from the operation to the postoperative treatment, and to ensure that the implant 20 is not affected by the transverse and longitudinal stresses. Loosening, the implant 20 and the tibial tissue maintain a close combination of optimal conditions. As can be seen from the above-described embodiments shown in the drawings and the drawings, the structure of the present invention serves as an implant in the dental implant structure, and has many advantages that are not available to a person after implantation. Therefore, the case has been progressive and in line with patent requirements. The above is only the preferred embodiment of the present invention and is not intended to limit the scope of the present invention. That is, the equal changes and modifications made by the patent application scope of this creation are covered by the scope of the creation patent.
