Description of the Invention: [Technical Field] The present invention relates to a dental implant. In particular, it relates to a dental implant having a proximal plate-like projection. [Prior Art] The bite force can be divided into a vertical force and a horizontal force. The vertical force of the dental implant is the compressive force at the bottom and the shear force at the side. The horizontal force is the tilting force of the dental implant. This means that the ends of the dental implant are most stressed and the force directions at both ends are opposite. The middle portion of the dental implant has a center of rotation. Since the horizontal force to the adjacent end side is supported by the adjacent teeth (or implants), such forces have less damage to the alveolar bone (alve〇lar b〇ne). The dental implant grasps the bone to resist the bite force. Therefore, it is necessary to allow the dental implant to grasp enough alveolar bone for the bite force and to protect the alveolar bone from being damaged. This is the basic and most important consideration for the design of the dental implant. Due to the advent of titanium dental implants, multi-dental implants continue to utilize the root shape of natural teeth. But in fact, the support mechanism of natural teeth is different from the support mechanism of dental implants. The natural tooth is suspended in the bone by the moving belt, and the implant is „fixed" to the bone. It is meaningless to imitate the root shape of the natural tooth. Referring to Fig. 1, the conventional dental implant 80 includes a central portion 81 and a plurality of fins 83. The central portion 81 is a tapered cylinder. The taper of the central portion of the dental implant 8〇 reduces the ability to resist vertical and horizontal forces. And as seen clinically, the deeper portion of the alveolar bone always has sufficient space for the dental implant. Another drawback of many current dental implants is the thread or fin 83. The thread or fin 83 is substantially a horizontal projection that protrudes from the center portion 81. Fin (horizontal projections) 112063.doc 1314858 • u is larger than the horizontal force but the vertical force to grasp the bone. This may explain why the success rate of the dental implant in the maxilla is lower than the success rate of the dental implant in the mandible. Because the dental implant in the upper collar receives more horizontal force than the dental implant in the mandible. : US Patent No. 4,738,623 discloses a dental implant that is endured by many dentists as the best dental implant system, but also has the disadvantages mentioned above. Like other dental implants, the entrance to the bone is the most vulnerable. Xi ♦ #牙 implant body seriously dealt with the problem. According to its manual, it is known that dental implants are implanted under the alveolar ridge 1 _~2 _. Later, some of the bones are removed and the struts and crowns are attached to conventional dental implants. However, as observed clinically, the bones will eventually return to the shoulders of the dental implants. Although the material of the dental implant is the same as that of the pillar body, the pillar body cannot be osseointegrated. There may be a micro-turn of the pillar body. A column that is not osseointegrated in the bone is a high velocity channel for harmful bacteria. Under a clear condition, the degeneration of the moon continues and the exposure of the dental implant is inevitable. This exposure is often on the horizontal force bearing side. Such exposure can make the patient feel • troubles are also a test for the dentist. SUMMARY OF THE INVENTION - The present invention relates to a dental implant. The dental implant of the present invention comprises: a center-to-night abutting convex plate and at least one fin, the central portion having a first portion, a flute-eight", a horizontal direction and a vertical direction. The abutting end protrudes from the first portion of the central portion in a horizontal direction and extends in a vertical direction. The fin protrudes from the second portion of the center portion in the horizontal direction. The dental implant of the present invention focuses on the horizontal force that is normally ignored by other dental implant systems. The dental implant of the present invention is provided by the provision of the sulcus bulging plate and the gap between the oral side and the lingual side 112063.doc 1314858 The bite force can be handled more correctly. The abutting end projections of the present invention capture more bone at horizontal forces and are free of most vertical forces. The abutting end projecting plate is produced from the cylinder toward the telecentric side or the proximal side. It does not have an abutting end projecting plate with respect to the oral side and the lingual side at the level of the abutting end projecting plate. Because the mouth and hyoid plates are always thin and are also a weakness in dental implants, it is best not to wear too much bone. The dental implant of the present invention further comprises a neck disposed on the first portion of the central portion. The voids and neck provide more space for the bone plate and transmit less force to the bone plate. Because of the reduced chance of neck exposure, the implant of the present invention provides ample space for the sheet which is undisturbed by any protrusions and which helps to meet aesthetic needs. The dental implant of the present invention is effectively treated by a sufficient bone structure around the plate-like projections. [Embodiment] Before describing the dental implant of the present invention, some terms must be clearly defined. The term "lower" is independent of gravity, which is expressed in deeper bones, and "upper" means that it is close to the gums or crown. And "oral" means the mouth or face, and, tongue " indicates tongue or sputum . "Vertical" means that in the direction along with the longitudinal axis of the dental implant, "horizon" is indicated in a direction perpendicular to "vertical". See Figures 2a, 2b, 2e, 2d, 2e *2f' which shows a dental implant according to the first embodiment of the present invention. The dental implant 2 is named as a type A dental implant, and the dental implant 2 of the present invention receives more horizontal force than vertical force (from occlusion) The type A dental implant will be used for the anterior part of the maxilla. See Figures 3 & 讣, 、, ^, and 3e' which show the dental implant 1 according to the second embodiment of the present invention. 3 Chu 112063.doc 1314858 3 Named B-type dental implants The dental implant 3 of the present invention will receive more vertical force. The dental implant of the present invention is often a cylindrical and non-tapered implant, which facilitates the connection of the prosthesis. Referring to Figures 2a to 2f, the dental implant 2 of the present invention comprises: a central portion 6〇, at least one upper abutting end projecting plate U, at least one fin 2〇 and at least one lower abutting end projecting plate 30. 6〇 has a first partial Η, a second portion 62, a third portion 63, a horizontal direction and a vertical direction. In this embodiment The central portion 60 is cylindrical in shape and does not taper. The central portion 60 further includes a neck (four) disposed on the first portion 61. The neck portion 10 has a grace of about 0.5 mm to 3.0 mm. The neck portion 10 has an edge 1 〇1, which has a plurality of round ridges, and the edge ι〇ι is inwardly and upwardly with respect to the longitudinal wheel of the dental implant. If mechanically permitted, the neck ι is preferably as narrow as possible. The neck 10 has a rim 1〇2, and the rim 〇2 on the neck 1〇 is narrower. The rim 1G2 toward the oral side is subjected to (iv) to simulate the curvature of the oral tooth silver. See Figures 2a and 4 'The modified rim 1〇2 starts from the abutting end side down to the oral side and is preferably concave. The modified rim 1〇2 will allow the surgeon to not worry about the dental implant on the oral side. In the case of exposure, the implant is not buried deep in the bone. The modified rim 1〇2 preferably matches the asymmetric absorbed ridge. The depth of the modified rim 1〇2 is at 〇5. The claw is added between 2 mm. Below the neck 10 is the upper abutting end projection 11 and the oral side or lingual space 12. The upper abutting bulge 丨i is horizontally The first portion of the core protrudes 'm straightly. In the embodiment, a plurality of upper abutments 112063.doc 1314858 4 are provided on the first portion 61 of the central portion 6〇. Preferably, the upper abutting end is convex. The ejecting plate 11 is completely cut at the upper edge to form the cut upper edge 111. See 圊5a, singular, and 5. 'It shows a top view of the different configurations of the upper abutting end bulging plate according to the present invention. The protrusions are produced from the central portion 60, as shown in Figure 5a, about 90 degrees from the tangent to the central portion 60, or as shown in Figure 5 and in Figure 5c, which is easy to manufacture and still for horizontal forces. Grab a lot of bones • The bulge of the head. Preferably, the upper abutment projections do not extend beyond the tangent to the mouth or tongue boundary. For the horizontal force, the abutting end projecting plate can better grasp the moon head and is protected from vertical force. This type of design prevents overload. The abutting end projections are approximately parallel to the adjacent abutting projections adjacent the abutting end projections. Referring again to Figures 2a to 2f, the upper abutting end projecting plate is disposed on the abutting end side of the first portion 61 and the first portion 61 has an oral side void 12 or a lingual space 12, both of which have no upper abutment The end projections, the oral side voids or the tongue side voids 12 are respectively disposed on the oral side and the lingual side of the first portion 6!. Also - that is, the relative position of the oral side and the lingual side of the upper abutting end projecting plate 11 - Λ, does not have the upper abutting end projecting plate. The void 12 is a protrusion. Because the mouth and hyoid plates are always thin and also a weakness in dental implants, the plate is best 'not tolerate too much force. Attached to the neck brace, the void 12 and the neck 10 provide more space for the bone plate ^ and transfer less force to the plate.

The length of the first portion 6 J 112063.doc 1314858 having the upper abutting end projections is about 1/4 to 2/5 of the total length of the central portion 60. Since the horizontal force is least felt in the middle portion of the central portion, The abutting end projecting plate does not appear in the middle portion of the center portion 6''. The abutting end projections include at least one locating abutment projections 112 that extend beyond the outer diameter of the fins 2''. Therefore, the width of the positioning abutting end projecting plate 112 is larger than the width of the abutting end projecting plate. In the present embodiment, δ is again placed on the abutting end side of the two positioning abutment end projecting plates 112' for positioning the dental implant 2. And after surgery, it is easier to keep the implant in the bone in the right direction. Further, the abutting end projecting plate includes at least one traction abutment end projecting plate 112. In this implementation, the fixed "terminal protruding plate is (4) the abutting end protruding plate. The length of the traction abutting end projecting plate 112 is higher than the length of the abutting end projecting plate 11, and the traction abutting end projecting plate 112 extends to the neck portion 1''. The traction abutment projection U2 has a traction hole 116 for enabling a pulling device (not shown) to be pulled out of the dental implant 2. In addition, the traction abutment projections can have traction slots for enabling a traction device to pull the implant. The abutting end projecting plate U comprises at least one common abutting end projecting plate. In the embodiment, the length of the ordinary abutting end projecting plate 113 is lower than the length of the traction abutting end projecting plate U2; and the common abutting end protrudes from the plate ι 3 The width is smaller than the width of the protruding abutting end projecting plate 112. That is, the normal abutting end: the width of the ejecting plate 113 is equal to the outer diameter of the fin. The abutting end projecting plate 11& includes at least one small abutting end projecting plate. In the embodiment, the length of the small abutting end projecting plate 114 is lower than the length of the ordinary abutting end projecting plate (1); and the small abutting end projecting plate ι 4 The width is smaller than the width of the ordinary adjacent 112063.doc 1314858 end protruding plate 1]. Therefore, the length of the abutting end projecting plate U gradually decreases from the traction abutting end projecting plate 112 to the small abutting end projecting plate 114, and the width of the abutting end projecting plate u is from the positioning abutting end projecting plate 112 to the small abutting end. The bulging plate 114 gradually becomes smaller. The upper abutting end bulging plate has an angle corresponding to the longitudinal axis of the dental implant. In the first embodiment, the angle of the plate-like projection is a twist. However, as shown in Fig. 6, the angle of the abutting end projecting plate may be between about 45 degrees. That is, the abutting end projecting plate 11 has an inclination angle of between 0 and 45 degrees. Adjacent to the abutting end projecting plate 11, the fin 2b projects in the horizontal direction from the second portion 62 of the center portion 6A. In the embodiment, a plurality of fins are disposed in a loop shape on the periphery of the second portion 62 of the center portion 60. The fins 2 do not shrink. The length of the second portion 62 having fins is about 1/5 to 1/2 of the total length of the central portion 6〇. The lower abutment end projecting plate 30 is disposed on the third portion 63 of the center portion 6A. The length of the third portion 63 having the lower abutting end projections is about i/4 to 2/5 of the total length of the central portion 6〇. In the present embodiment, it is suggested that the abutting end projecting plate: the projecting angle is perpendicular to the tangent of the center portion 60. The lower abutment end projection plate % has a cut lower edge 301. Near the bottom 31 of the central portion 60, the edge of the lower abutment end projection 30 is cut to match the bottom of the bone socket (b〇ny s〇eket); that is, the shape of the drill bit is matched. The central portion 60 further includes a bottom portion 31 and a well 13. The bottom is flat. The well 13 is attached to the pillar body and has an opening at the top of the central portion 60. Referring to Figures 3a, 3b, 3c, 3d and 3e, the present invention is one of the first embodiment of the second embodiment of the dental implant 112063.doc -11 - 1314858 The body 3 comprises: a central portion 7〇, at least one abutting end projecting plate “and at least one fin 50. The central portion 7〇 has a first portion 71, a second portion 72, a horizontal direction and a vertical direction. The central portion 70 further comprises a setting The neck portion 40 on the first portion h. The neck portion 4 of the second embodiment is similar to the neck portion of the first embodiment, but the neck portion 40 here is shorter. The neck portion 4 includes the rim 4〇 The rim 4〇1 is flat or less modified. The length of the neck 4〇 is between 〇5111111 and 2, and the depth of the modified rim is recommended to be 〇_5mn^|jl2mm. The horizontal direction is extracted from the center portion of the core portion and extends in the vertical direction. The abutting end projection plate 41 and the gap 42 on the oral side and the lingual side are also similar to those previously described in the first embodiment. The length of the first portion 71 having the abutting end projecting plate 41 is about 1/6 to 2/5 of the total length of the center portion 7''. The positioning abutment end projecting plate and the traction abutment end projecting plate 412 are similar to those described in the first embodiment. The fins 50 project in a horizontal direction from the second portion 72 of the central portion 7(). The center (four) step-by-step includes The bottom 51 and the well 43. The fin 5Q continues down to the bottom 51 without shortening its diameter. The bottom 51 is concave. Since the bone at the bottom receives the contraction force 'the concave bottom 51 can disperse the force. It is especially important for short dental implants with a diameter. If any deeper length is important, then a special design of the drill bit is required to perform the bottom of the bone socket. The above examples are merely illustrative of the principles of the present invention and The present invention is not limited to the scope of the present invention, and the scope of the present invention should be as described in the following claims.
