I 3 i 5 201212893 Sex. More importantly, through the development of new dental implants, dentists and orthopedics are encouraged to provide this service to patients. New implants can reduce the nerve damage caused by implant surgery, increase the initial stability, and reduce the operation of patients. Injury, shorten the time of surgery, shorten the time required to load dentures, increase the amount and quality of bone sticking, avoid additional bone grafting, increase contact between implants, abutments and screw surfaces, thereby improving stability and sputum The success rate of the complex reduces the difficulty of technical application. SUMMARY OF THE INVENTION A primary object of the present invention is to provide a dental implant that can increase the amount and quality of bone sticking. Another object of the present invention is to provide a dental implant that can be conveniently used to reduce the technique. Difficulties in application. Another object of the present invention is to provide a dental implant which provides an initial stability of maximum φ. Another object of the present invention is to provide a dental implant that enhances the protection of bone. Another object of the present invention is to provide a dental implant that can (10) rotate without post-operative implants. Another object of the present invention is to provide a dental implant that avoids loosening of the screw from the abutment, which is the most common cause of treatment failure after treatment. 201212893 Another aspect of the present invention is the self-seeking, 彳(4)-ton success rate, and avoiding unnecessary ❹ 物 同Another goal of this month is to provide a dental implant that reduces the time required to hold dentures and overall treatment. Another object of the present invention is to provide a dental difficult body that allows for changing the position of the rim of the iliac complex. Another object of the present invention is to provide a cure for the neck, which can improve the neck slope to the gums, thereby avoiding damage to the alveolar bone. Thus, in order to achieve the above objects, the present invention provides a dental implant comprising: a body of a dental implant. A root tip ring lock. The outer side wall of the implant has asymmetric threads on the outer side of the implant, and the outer side wall of the root of the implant has a helical sharp cut end. A complex of three root grooves. The Felot torus provides extra stability and aesthetics and functionality. The neck bevel can change the design of the edge of the complex. The neck step can change the design of the edge of the complex. The largest hex lock is located inside the implant and provides maximum friction between the abutment and the implant. 201212893 The root sinus push-up end is located at the end of the implant. The features and advantages of the present invention can be more specifically embodied by the following detailed description. [Embodiment] Figure! Fig. 3 is a front view of the root implant of the present invention. It can be seen that the shape of the root implant 1〇 is __, which is like 丨 -12. Twisting is used to insert the corresponding position on the bone, while the top 12 is matched by the screw and the abutment (9). The root of the root implant 1G has an asymmetrical snail (10), the bottom end 11 has a root tip ring lock 30, and the top end 12 has a maximum hex lock 40. The root implant 10 has an annular section between the bottom end U and the tip end 12, and a tapered insertion end near the bottom end 11. This design allows the dental implant 1G to be more easily inserted into the bone. in. The top end 12 includes a Filo annulus 5〇 and a platform 16. The platform 16 is located at the topmost end of the root implant for mating with the abutment 60. The present invention allows both the tip 12 to mate with the abutment (9) on the silver of the teeth and also allows it to mate with the abutment 6 under the gums. There is a neck bevel or a neck step between the top end 12 and the asymmetrical thread 2〇, which is designed to allow the teeth to align the edges of the complex. Depending on the condition of the sinus, the size of the dental implant will vary, and the dimensional change will be mainly reflected in its length and width. The asymmetrical thread 20 is attached to the outer side wall of the dental implant 1 位于 between the annular surface and the bottom end u. The asymmetrical thread 20 can be a continuous thread or a segmented continuous function that locks the implant 1 on the bone after the dental implant 10 is inserted into the bone of the sinus. 8 201212893 As shown in Fig. 3, the thread 20 in the present invention has an asymmetrical design, that is, the screw _ has a single oblique angle on both sides. As can be seen from the cross-sectional view of Fig. 3, the asymmetrical thread 2〇 includes a bevel 21 and a bevel 2 & The beveled surface 21 faces the bottom end 1 of the dental implant 10 and has a smaller angle of inclination. The beveled surface 22 faces the tip end 12' of the dental implant 1G, which has a large inclination angle. In other words, the bevel 22 is steeper than the bevel -21. When the dental implant is inserted, there is less resistance because the bevel - 21 _ oblique angle is smaller. Compared with τ, the inclination angle of the slanting surface 22 is large, and when the dental implant is tilted from the money, the age is large. Therefore, in terms of inserting the alveolar bone and increasing the woven thief species, the exclusive 2 〇 has a better effect in inserting the bone and improving the initial stability of the implant. As shown in Figure 3, the asymmetric thread design includes a length of main thread 25 and a length of tail thread 26, wherein the tail thread 26 is adjacent the bottom end 11 of the implant and the main thread 25 is located between the neck bevel 4 and the tail thread 26. The depth and pitch of the tail threads 26 are smaller relative to the main thread 25. As seen in Figures 3, 4 and 7, the details of the first portion 45 of the largest hex lock 44 can be seen. The wall of the largest hex lock has a total of four layers of retention. The first layer 451 is adjacent to the platform 16, and is formed by six planes 4511 and six vertical curved surfaces 4512 at an angle of 90°, and further includes six sets of 12 turns. Groove. The first layer retention function cooperates with the undulating protrusion portion 611 on the abutment to greatly improve the stability between the dental implant and the abutment. The second layer 452 is composed of six vertical lobes 4521 and six vertical circular faces 4522 (depth 1.2 faces to 1.3 mm). The third layer 453 includes six curved faces. There are two angled planes 4531' between each adjacent two curved faces. The two planes have an angle of 12 inches. . The fourth layer 454 is a 360° circular wall. 201212893 Depending on the hardness, bones can be divided into sounds. The first category represents the hardest bone and the fourth category represents the softest bone. As shown in Figures 1 and 3, the asymmetrical threads have cutting edges 23 which are located at the top of the beveled one and the beveled surface 22. The cutter 23 can easily cut the third and fourth types of bones, and will also reduce the resistance encountered when cutting the first and second types of bones. When the dental implant is held into the third or fourth type of bone, the cutter 23 can be directly cut into the bone without the need to actually perform the implant surgery. The collection - or the second shouting head, can also cut the amount of bones in a large area. This is the most important age, and the stability and success rate of this dental surgery is critical. In addition, the cutting edge 23 on the asymmetric thread 2G can greatly reduce the heat generated during cutting/cutting, thereby shortening the operation time. The heat generated during the surgery and the operation time also affect the success rate of the operation. In order to improve the efficiency of the dental implant when it is inserted into the bone, the design comprises three root groove complexes evenly distributed at the insertion end of the dental implant 1G. As shown in Fig. 3 and Fig. 3, each of the root groove complexes 13 has a V-shaped cross section which is formed by cutting the dental implant 10 from the bottom end u from the bottom end 131 to form a "over the cut surface 131". A section of the asymmetrical thread 2〇 is seen, and the cutter 23 also forms a tangent point 24 here. When the dental implant of the present invention is inserted into the bone, the 'Na 24 will be the first bone. If the bone is too hard, some of the bone will be pushed into the root groove complex 13 by the point 24. As can be seen, the dental implant of the present invention has a total of three sets of root groove complexes 13. As shown in Fig. 3 and Fig. 5, the root tip ring lock 3 is located at the bottom end of the dental implant 1〇. The root tip ring lock 31 has a root tip cavity 31, and the root tip cavity 31 includes a cavity bottom 32 and a cavity wall 33 cavity. The wall 33 forms a cavity edge 34 where it is joined to the circumference of the circle 201212893. The lumen edge 34 defines the root tip 35 which allows the bone to grow into the apical cavity 31. A lock element 36 is included in the root tip cavity 31 of the root tip ring lock 30. The lock element 36 includes grooves and flanges to increase friction. In the present invention, the lock element 36 is a set of internal threads on the cavity wall 33. In the opposite case, the face can be made more blood after the implant surgery, so the dental implant can better integrate with the bone in this area. The phantom space of the root tip allows the bone to grow in Φ and grow into the groove of the thread, creating a locking mechanism to ensure long-term bonding of the dental implant and bone. One of the failures of dental surgery is the loosening of the implant. It can be removed from the alveolar bone before the implant and alveolar bone are combined. It is worth noting that the direction of the threads on the cavity wall 33 is exactly opposite to the direction of the asymmetric threads 20. That is to say, when the external force tries to loosen the solid formed by the asymmetrical thread, the internal thread inside the root tip ring lock 3 is simultaneously crushed. Thus, the two effects mutually prevent the release of the wrong body. 3 and 5, the root sinus push-up end 37 is a narrow plane located at the bottom of the dental implant 1〇. The three root groove complex 13 has a slight contact with the root sinus push-up end 37. The apical cavity 31 occupies most of the center of the platform, turning the platform into a thin, pointed ring. When the root sinus push-up end 37 of the dental implant 10 is screwed into the sinus, the ascending end of the root is in contact with the bottom layer of the sinus. At the bottom of the sinus, the torsion is converted into a linear force due to the action of the asymmetrical thread. The root sinus push-up end 37 will undergo bone expansion from its outer wall. At the same time, the push-up end 37 of the root sinus will penetrate deeper into the sinus, thereby enhancing the bottom of the nose. Due to the sinus lift and bone expansion, the dental implant is locked more firmly. 11 201212893 As shown in Fig. 1 'Fig. 4 and Fig. 7, the maximum hexagonal lock 4 of the dental implant 10 ± is intended to accommodate the abutment 60. The maximum hex lock 40 has two parts: a lock chamber 41 and a thread lock 42. At the top end 12, the lock chamber 41 has a lock port 44' which extends vertically into the interior of the implant. The lock chamber can be divided into first and second portions, the first portion 45 is adjacent to the lock port 44, and is used to position the hexagonal root portion 61 'plane 4531 of the support 6〇 and the hexagonal body 613 of the abutment 60. The cooperation is relatively loose. As shown in Figs. 4 and 8, the first portion 45 of the lock chamber 41 is a φ hexagonal cylindrical rod 83 for arranging the implant fixing driver 8〇. The fit of the hexagonal cylindrical rod 83 of the flat surface is relatively loose. The snap ring 831 on the hexagonal cylindrical rod 83 is tightly fitted to the flat surface 4531 so that the dental implant 1 can be caught and placed in the alveolar bone during the implant surgery. The second portion 46 is adjacent to the first portion 45 and is located deeper in the lock chamber. The thread of the threaded lock 42 is distributed over the inner wall of the second portion. The threaded lock 42 is for mating with the screw 7〇. After the implant is fixed in the bone, the abutment 6 can be placed. First, the hexagonal root portion 61 of the abutment 6 is inserted into the first portion 45 of the lock chamber 41, and then the support 6 is fixed to the implant with a screw 7〇. The through hole 62 inside the lug support 60 connects the lock port 44 and the second portion 46 of the lock chamber 41. The top portion 71 of the screw 70 has an external thread 72' which is connected to the internal thread of the implant through the through hole 62, and the head portion 73 of the screw 7 is retained in the through hole 62 to fix the abutment 6''. The metal fit between the screw 7〇 and the dental implant 1〇 securely secures the abutment to the implant 1〇 for maximum stability. It is worth mentioning that the traditional dental implant has only three bayonet openings for interfacing with the three jaws of a conventional abutment. Thus the abutment must be rotated 12 turns. In order to find the next installation position, there are a total of three installation positions L which are extremely inconvenient in the age of the anchor, especially for angled abutments. As shown in Fig. 4, the third layer of the first portion of the lock chamber 41 [201212893 453 has six pairs of planes 4531 which are evenly distributed around the wall of the implant 10 about the central axis of the implant 10. In this case, the angle between two adjacent money positions is from 120. Reduced to 6〇. The number of installation locations has increased from the previous three to six. It is therefore easier to find a suitable assembly angle' and to simplify the alignment of the crown. (1) Under very bad circumstances, 'because some of the sinus _ s Zhang, so there is not enough space to place the whole implant' (2) and some cases, when the alveolar nerve and alveolar ridge are very close, #also no Sufficient work space to place the entire implant. In this way, the dentist can retain part of the neck slope or neck step outside the tooth silver to avoid damage to the nerve tissue. The dental implant of Fig. 1 S3' Fig. 4 and Fig. 6' has a neck bevel 14 or a neck step 17 between the Felot annulus 50 and the annular surface 15. The neck slope u is formed by the tapered surface (4) extending upward from the annular surface 15 to the Feiluo annulus 5〇. The neck bevel 14 thins the top 12 of the implant 10' but is said to increase the width of the implant. The neck bevel 14 can be a smooth, thick or threaded bevel. _ ® 6 shows another dental implant with a neck step 17 of the present invention. The neck step 17 includes a plurality of step faces 172 and a plurality of slopes 171. This type of dental implant can be evenly distributed between 2 to 6 steps between the Ferro ring surface 50 and the annular surface 15, the width of the step is between 〇.lmffl to 〇.5, oblique® 171 and The angle between adjacent steps δ172 is between 45. To 15 baht. between. The neck step 17 will slightly reduce the thickness of the top 12, but it gives more room for the bone to grow' so there will be better bone stickiness. The neck bevel 14 and the neck step I? are designed for aesthetics, stability and safety, allowing the dentist to leave a part of the implant in the gums during tissue atrophy, technical difficulties or safety hazards. Come up to change the edge position of the 201212893 body or crown to enhance the appearance. In many clinical applications, the depth of the alveolar bone is not sufficient to accommodate the entire implant. In order to prevent the implant from injuring the alveolar nerve or the gum tissue, the dentist may choose to retain the neck bevel 14 or a portion of the neck step 17 on the gum. The exposed part can be covered with a sputum complex or ceramic crown to create a tooth color that enhances aesthetics. The neck bevel 14 and neck step 17 of the present invention may illustrate the surgeon's ability to control the depth of insertion of the implant. With the design of the neck bevel 14 and the neck step π, the chance of injury to the alveolar nerve during surgery is greatly reduced. Because the damage to the alveolar nerve is a major part of the medical malpractice claim, the design of the neck bevel 14 and the neck step 17 can greatly increase the safety of the implant surgery. In addition, by placing the edge of the iliac complex at a position closer to the tip of the root, the degree of solidification can be greatly increased. Also, whether it is to retain the neck slope 14 and the neck step 17 on the silver or all of the teeth silver, the alveolar bone can grow along the slope or the step, so as to reach _ Implant, avoid displacement, resist thrust and pull. As a result, the life span of the implant and the scorpion complex will be greatly improved. As shown in Figures 1 and 5, the dental implant 1 has a Ferro annulus 5 〇 located at the top of the implant 1 。. The Fello torus 50 is actually a chamfer 51 located at the circumferential edge of the tip 12. The 5's of the Fello torus increases the thickness of the top 12. Designing the Ferro Ring _ The purpose is to improve the appearance and improve the stability. If the insertion depth of the implant 1G is not enough, the part of the implant will be exposed to the outside, which will affect the appearance. The Ferro torus 5G in the present invention indicates that the surgeon controls the implant during the operation, the gums should be reduced, and the lion is thick and thick, and the exposed area of the implant is also reduced, and the implant is improved. stability. In addition, the ceramic material edge of the sputum complex can cover the exposed part of the implant, further improving the appearance and improving the function of the light body. 201212893 As shown in Fig. 2'Fig. 3, Fig. 4 and Fig. 7, the hexagonal root portion 6i of the support 6〇 is inserted into the lock chamber 41 of the implant 1,, and the first layer of the pottery 451 and the support _ The undulating protrusions are closely fitted, and the Ferro body 60 is engaged with the chamfer 51 on the implant 10. These two retention functions can greatly improve the stability between the implant 10 and the abutment 60. In summary, the present invention is an automated or non-f-drilled dental implant that uses asymmetric threads 20 to simplify surgery and increase stability. Asymmetric thread 2 () (four) illusion and cut point money _ when the maximum protection of the bone. The root cavity 31 of the root tip ring lock 3 allows the bone to grow therein. The internal thread 36 increases friction and thereby increases the stability between the abutment and the implant. Further, since the direction of the internal thread 36 and the direction of the asymmetrical thread 20 are opposite, it is possible to prevent the implant from coming loose. There is also a 'root root ring lock 3' with a root sinus push-up end 37, which can raise the sinus during implant surgery. The present invention also provides a larger mounting position for the center 45 of the locking chamber 41 of the support 6() __ ι by the gold hybrid, thereby greatly simplifying the installation and calibration. The neck bevel 14 and the neck step 本 in the present invention may indicate that the physician controls the implant's __ ι4 and the purchase step 17 to allow the bone to grow along the slope or step, so that the implant can be fixed step by step. The Felot torus can be used to indicate where the physician controls the implant's fixation and reduction of metal exposure.
