DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to an artificial tooth root for implanting teeth, and more particularly to an artificial root having a plurality of protruding structures. [Prior Art] In the field of dental technology, the use of dentures, braces or bridges has traditionally been used to repair the interdental structure of the teeth, but this way to the adjacent healthy teeth will have an unnecessary influence. It is necessary to cut the healthy teeth before and after the missing teeth as a solid pillar to provide enough space to accommodate the advancement of dentures, braces or teeth with the technology. Currently, it has developed φ 锸 m m. The technique of implanting artificial roots directly into the alveolar bone completely replaces the teeth of the singularity. Since artificial implants do not need to be attached with other devices and support the adjacent teeth, it is less likely to damage the adjacent natural teeth and prevent the atrophy of the alveolar bone and the flesh, and maintain the health and function of the sigma cavity for a long time. Ο In the 1950s, Swedish scientists M (10) (10) geologists further discovered that Chin metal has local biocompatibility, and proposed the concept of osseointegrator & (d). In particular, money records are repelling or inflamed to the human body U, and the bone tissue is easy to grow on the surface of the titanium metal and directly bonded to the titanium metal, and thus is widely used for making artificial roots. In this way, the combination of the root of the jade tooth and the alveolar bone is not purely dependent on the mechanical force, but also uses the bio-surface bonding force to achieve a better combination effect. The process of implanting teeth can be roughly divided into two stages. In the first stage, the hole is drilled in the alveolar bone, and the artificial root is placed in the human body; since the period of the bone tissue growth is required to avoid the stress period (stress such as e Peri0d), the micro movement should be avoided as much as possible (micr) 〇_m〇ti〇n) 200940032 After the artificial root surface is on the surface of the artificial root, it is better to temporarily suspend the teeth and produce the meat. The roots of the artificial roots have been tightly combined and then the whole skeletal period. Organization and abutment!!] In the first stage of the person's re-entry, re-open the flesh and make the artificial artificial roots to make the final # combination of dentures to the abutment. The purpose of the alveolar bone is that the 'form' can be locked in the operation and rotation mode by mechanical force and the root of the alveolar bone and the alveolar bone are combined at the initial stage, and the thread can be locked in the process. And weaving can grow on artificial roots. However, hurt. If the heat is generated in order to reduce the force of the 7-force, it will cause too much time for the bone tissue, and the creator will be locked by the tr-speed method, which makes the surgery discomfort. The conventional technique shortens the Si+ a integration effect during surgery, presents a dilemma of I-like time and improves the bones. This provides the artificial root of the joint, α, and osseointegration effect: the surgical procedure The damage caused by bone cells and the promotion of the roots are the goals that the industry has hoped for. SUMMARY OF THE INVENTION The present invention is directed to providing an artificial root that enhances the effect of osseointegration. The osseointegration effect can be enhanced by the protrusion structure of the artificial root surface to increase the surface area of bone cell growth by the bone integration stage after implantation of the artificial root. Another object of the present invention is to provide an artificial root that is easy to implant. Because the protruding structure of the surface is designed to be easy to implant, it can effectively shorten the operation time and improve the frictional heat damage of the bone tissue in the prior art. The shortcomings. The invention further aims to provide a human root, which can be processed into a protruding structure by forming a longitudinal and lateral staggered groove on the surface, so that the artificial root of the invention has low cost in 200940032. Advantage. A further object of the present invention is to provide an approximation of the surface features of an artificial artificial tooth root, so that the artificial root can form a better stress distribution between the bite and the alveolar bone after the osseointegration is completed, thereby avoiding stress. Concentration causes damage to bone tissue. In order to achieve the above object, the artificial tooth root disclosed in the present invention comprises a body portion having a plurality of longitudinal grooves and a plurality of lateral grooves disposed on the surface of the body portion and separated from the longitudinal direction and at least A peripheral direction extends to form a plurality of raised structures. The technical spirit and the object of the present invention, as well as the technical means and preferred embodiments of the present invention, will be readily apparent to those skilled in the art. [Embodiment] The preferred embodiment of the human body disclosed in Shuming is shown in the figure. The artificial root 1 includes a body portion u, an end portion 15, a crown portion 16, and a neck portion 17, wherein the end portion 15 is formed at one end of the body portion u, and preferably has an arc shape. The portion 16 is disposed opposite the end portion 15 with the neck portion 17 interposed between the body portion 11 and the crown portion 16. Since the artificial tooth root i is implanted, the η portion corresponds to the silver portion of the tooth and the silver tissue is difficult to form a substantial biocompatibility between the metal and the metal. Therefore, the neck portion 17 is preferably designed to have a crown portion 16 The gradual smooth surface forms a better affixing effect with the gum tissue. However, any person skilled in the art can also appropriately change the contour of the head of the 200940032, which is not limited herein. The present embodiment is characterized in that a plurality of longitudinal grooves 12 and a plurality of lateral grooves 13 are provided on the surface of the body portion 11 to form a plurality of protrusion structures 14. More specifically, the longitudinal grooves 12 extend substantially in parallel along a longitudinal direction, and the lateral grooves 13 extend substantially in parallel along a peripheral direction. As shown, the longitudinal direction is substantially perpendicular to the surrounding direction. Therefore, the longitudinal groove 12 and the lateral groove 13 are also substantially perpendicular. The longitudinal grooves 12 and the lateral grooves 13 of this embodiment can be designed to have different cross-sectional shapes. Please refer to FIG. 2A , which is a schematic cross-sectional view of the first plan taken along line 2A-2A of the scraping line. It can be clearly seen from the relationship between the protruding structure 14 and the longitudinal groove 12 that the longitudinal groove 12 has an angular shape. Moreover, the protruding structure 14 also has an angular cross-sectional structure in the peripheral direction. Similarly, please refer to FIG. 2B, which is a schematic cross-sectional view along the 2B-2B section line in the longitudinal direction of FIG. 1. The relationship between the protrusion structure 14 and the lateral groove 13 can be seen. It has a trapezoidal angular profile. φ However, the longitudinal groove 12, the lateral groove 13 or the protruding structure 14 is not limited to the above-described angular shape. As shown in Fig. 2C, the protrusion structure 14 and the groove may have a triangular-like cross section; or as shown in Fig. 2D, the protrusion structure 14 has a triangular-like cross section, and the groove has a trapezoidal angular scraping surface. It should be noted that the shape may be an angular structure of various symmetry, asymmetry, or a polygonal shape, and the plurality of longitudinal grooves 12 and the lateral grooves 13 may be alternately designed with different scraping shapes, which are not limited herein. . Alternatively, the longitudinal groove 12, the lateral groove 13 or the protrusion structure 14 may also be an arc-shaped structure, see FIGS. 2E and 2F, wherein FIG. 2E shows the protrusion structure 14 having an arc 8 200940032 profile. And FIG. 2F shows a groove having an arcuate cross section; in addition, the shape of the arc may be symmetrical or asymmetrical. All of the above-mentioned shapes, such as the angles and the arcs, can be combined according to actual design requirements, and are not limited herein. Those skilled in the art can use the cutting longitudinal grooves 12 and the lateral grooves 13 to have different sections according to their knowledge. The shape, and thus the formation of the raised structure 14, has a predetermined cross-sectional shape. Preferably, the body portion 11 may have a shape that is tapered toward the end portion 15 (not shown). It is conceivable that the body portion 11 having a tapered configuration will facilitate the implantation process of the artificial root 1 . And when the bite is completed after the completion of the implant, a better stress distribution is exhibited. Referring to FIG. 2A again, the protruding structure 14 disclosed in this embodiment has a center distance W1 and a height H1. Preferably, the height H1 and the center distance W1 are between about 0.1 and 3 millimeters. Better results are achieved during osseointegration or surgery. It should be noted that the direction defined by the center distance W1 is not limited and can be applied to the longitudinal direction or the surrounding direction. In addition, the artificial root 1 of the embodiment may further include a connecting structure 16a disposed in the crown portion 16, and combined with a table (not shown) in the second stage to further accept the crown. Or artificial teeth. The connecting structure 16a can be a screw hole for the support to be screwed. The material of the artificial root 1 is preferably titanium or titanium alloy, so that the artificial root 1 is highly biocompatible. Another preferred embodiment of the present invention is shown in Fig. 3. Similar to the previous embodiment, the artificial root 3 includes a body portion 31, an end portion 35, a crown portion 36 and a neck portion 37. The body portion 31 forms a plurality of 200940032 protrusion structures by the longitudinal grooves 32 and the lateral grooves 33. 34; a connecting structure 36a 'for example, a screw hole' may be formed in the crown portion to be connected to a table (not shown) after the end of the osseointegration period. The present embodiment is characterized in that the lateral grooves 33 are substantially simultaneously formed by a threaded structure and are interleaved with the longitudinal grooves 32 to form a protruding structure 34. The connection relationship between the body portion 31, the end portion 35, the crown portion 36, and the neck portion 37 has been described in detail in the previous embodiment, and will not be further described herein. In summary, the artificial root disclosed in the present invention can reduce the generation of frictional heat during implantation to avoid bone tissue damage. The present invention utilizes a relatively simple method of forming a longitudinal groove and a lateral groove on the surface of the body portion to form a plurality of geometrically contoured protrusion structures, thereby providing sufficient contact area for bone cell growth after implantation of the artificial root. , thereby shortening the osseointegration time and achieving better bone integration. The above embodiments are merely illustrative of the principles and effects of the present invention, as well as the technical features of the present invention, and are not intended to limit the protection of the present invention. Anyone skilled in the art can do without departing from the technical principles of the present invention. And the spirit of the changes, the arrangements that can be easily completed or the equality are all within the scope of the invention. Therefore, the scope of the present invention should be as described in the following claims.
