Therefore, the utility model discloses a thin dental pile is equivalent to the reinforcing bar, and the filler is equivalent to cement, has installed the broken tooth of thin dental pile, or the tooth root, or the ossicle, is equivalent to reinforced concrete's basis, utilizes the filler that the adhesion is strong, firmly bonds them together, becomes an organic whole, becomes a new enough strong new dental pile, installs the dental crown on it, has just accomplished the utility model discloses a plant tooth.

The utility model is inspired by the minimally invasive surgery, the minimally invasive surgery is only on the body, and on the chest and abdomen, a small hole is opened, the surgery can be performed, and the injury to the human body is small, thereby having great advantage. Therefore, the utility model adopts the mode of drilling the pores on the broken teeth, on the tooth root and even on the gum, namely on the tooth bones, and the pores are opened, so that the utility model can be applied to the broken teeth, on the tooth root and on the tooth bones, the tooth planting of the utility model can be implemented without pulling out the teeth, and the tooth planting can be implemented after several months.

Fig. 1 is a schematic view showing an example in which two pores 1 are drilled in a broken tooth 51, and only the broken tooth 51 and a root 52 therebelow are shown in the figure, and in the case where the broken tooth 51 is sufficiently strong, the pores 1 may be directly drilled in a rough cross section at the broken portion of the broken tooth 51, and the pores 1 may be drilled in an appropriate position without leveling, even if the cross section is inclined, but rough, and in the figure, the two pores 1 are drilled in the broken tooth 51. The diameter of the pores 1 may be 0.3 mm, or 0.1 to 0.6 mm. Finer is preferable. For example 0.3 mm. The depth of the pores 1, preferably between 2 mm and 5 mm, may be as deep as practical, for example to 7 to 15 mm, or even into the root 52, but usually 3 to 5 mm! Due to the pores, the two pores 1 are spaced by 3, 4 mm, even 5 to 6 mm. This is an advantage of the pores 1. Since the biting force of the tooth is a compressive force, there is no problem in using the implant as long as the adhesion between the fine dental stump 2 attached to the fine hole 1 and the filler 4 and the crown 5 is strong.

The drill hole 1 may be drilled by a mechanical drill, or may be drilled by ultrasonic or laser drilling, in any manner. As to why it is recommended that the diameter of the fine holes 1 is about 0.1 to 0.6 mm, since the diameter of the needle for sewing clothes which is commonly used is also such a size, it is known that the sewing needle has sufficient rigidity. The fine holes 1 cause little damage, which is beneficial to the patient. The diameter of the acupuncture needle used in medical science is usually about 0.2 to 0.3 mm. The pores 1 described in the present invention are all such pores. The diameter of the pores 1 can be selected by a physician according to the circumstances.

Fig. 2 is a schematic view of an embodiment in which a fine hole 1 is drilled in a root 52. Many people, the tooth is lost and the root 52 is intact, so that the fine hole 1 can be drilled in the root 52. In this embodiment, only one fine hole 1 is drilled, which is an illustration, and the present invention can be implemented by drilling only one fine hole 1. The diameter and depth of the fine pores 1 are the same as those described with reference to fig. 1. The root 52 is sufficiently strong and it is also sufficiently strong that a hole 1 is drilled in a suitable position of the root 52, for example in the middle, and only one thin stump 2 is mounted thereon. This is the simplest implementation. Of course, because the lower surface of the tooth root is in a two-branch structure, two pores 1 and three pores 1 can be selected, and two or three thin tooth piles 2 can be placed.

Fig. 3 is a schematic view of an embodiment in which a fine hole 1 is drilled in a tooth bone 53 below a root 52. In the case where the root 52 is not rotten, the root is cleaned, and the root is placed on a bed below the root, or a bed bone, referred to as a bone 53 in the present specification, and a fine hole 1 is drilled in the upper surface of the bone 53, and an example of three fine holes 1 is shown in the drawing, the three fine holes 1 are arranged in a substantially triangular shape, the fine holes 1 are spaced apart by about 3 to 6 mm, and the fine holes 1 are oriented in a slightly oblique upper direction toward the crown 5 to be fitted. Due to the fine holes 1, a plurality of, for example, 3 to 5, can be drilled in the dental bone 53 without damaging the dental bone 53 itself. Even if the position is deep, one, two, three or four pores 1 are conceivable embodiments.

Referring to fig. 4, fig. 4 shows an example of the thin dental stump 2, which is a needle-shaped round rod with a wire wound around the upper portion thereof, and is constructed like an acupuncture needle. The lower part of the spiral rod is an insertion section 2-1 which can be inserted into the pore 1 and is a round rod, and the upper part of the insertion section 2-1 is a spiral section 2-2. Is a round bar and a wire is wound around the outside of the round bar. The dental stump 2 has sufficient rigidity, sufficient toughness, no deformation, hardness like a sewing needle, and no fracture. Therefore, it is necessary to use stainless steel, alloy steel, and other metals and alloy materials. The used sewing needle has good rigidity, can be broken, has poor toughness, is bent and has good toughness, can not be broken after being bent for several times, but has poor rigidity. The fine tooth pile 2 in the utility model is hard enough and can not be broken like a steel needle. The structure of the insertion section 2-1 is a needle-shaped thin round rod structure, the thickness and length of which are matched with those of the fine hole 1, and the thickness of which can be relatively tightly inserted into the fine hole 1 is best, and the diameter of which is also 0.1 to 0.6 mm. Instead of a round rod, a cylindrical rod, a hexagonal rod, an octagonal rod, and various shapes may be used, and the rod may be inserted into the inside of the pore 1 in a tight fit manner. Because an adhesive is used during the insertion, a circular prism, such as a hexagon, an octagon, etc., which is used to firmly adhere the fine tooth pile 2 to the wall of the fine hole 1 can accommodate more adhesive. Regarding the size of the dental pile 2, the insertion section 2-1 is fitted into the fine hole 1 in correspondence with the depth of the fine hole 1, typically several millimeters. Regarding the spiral segment 2-2, if it is mounted on the broken tooth 51, it is shorter, about 3, 4 mm in height, about 3 to 6 mm in height, about 15, 16 mm long if it is mounted on the tooth root 52, and about 53 mm long if it is mounted on the tooth bone 53. According to specific conditions. Its transverse dimension, i.e. the direction perpendicular to the insertion section 2-1, may be in the range of about 2 to 3 mm. The structure may be various, for example, a structure in which a spiral wire is wound around a needle shaft, such as a shaft of an acupuncture needle, and the like, and several embodiments are illustrated in the following for further explanation.

Referring to fig. 5, fig. 5 shows another embodiment of the fine dental pile 2, which is characterized in that the upper spiral section 2-2 is constructed as a cylinder having a central axis, the central axis is fixed by a plurality of support bars extending up and down from the central axis, the diameter of the cylinder is, for example, 2 to 3 mm, and the wall thickness is, for example, 0.1 to 0.3 mm, so that the filler 4 can be injected into the cylinder.

Fig. 6 shows a fine dental post 2 in the form of a straight round rod, in which shallow micro-pits 7 are formed on the surface thereof, for example, by laser drilling, which does not affect the stiffness, strength and hardness of the fine dental post 2, but a little filler 4 can be contained in the micro-pits 7 in order to increase the contact area with the filler 4.

Fig. 7 is a view showing an example in which a thread structure is formed on the surface of the insertion section 2-1 of the fine screw pile 2, and various shallow thread structures can be used without affecting the rigidity, strength, hardness and toughness of the entire fine screw pile 2, in order to increase the amount of the binder 4 used so that it is more firmly bonded to the inner wall of the fine hole 1. In the figure, its helical section 2-2 is still in the configuration of a wire wound around the central rod.

Fig. 8 shows a further embodiment of a fine dental pile 2, the insertion section 2-1 being a round rod, for example with a diameter of 0.4 mm, and the screw section 2-2 also being a round rod, but with a larger diameter, for example 2 to 3 mm, being a solid round rod.

The adhesive can be any adhesive available in the prior art, such as the adhesive commonly used in dentistry, and even the glue 502, the newly invented glue 8000 and the like can be used. Many existing adhesives can firmly bond bones and metals, and can be used as long as they are harmless to the human body.

Fig. 15 is a schematic view showing an example in which three thin dental piles 2 are installed on a dental bone 53. Since the tooth bone 53 is at a deep position, the spiral section 2-2 of the fine tooth post 2 can be as long as about 1 to 3 cm. The inventive fine dental post 2 is sufficiently rigid, and the use of a long fine dental post 2 also results in a non-problematic implant.

Fig. 16 is a schematic view showing an embodiment in which two thin tooth piles 2 are installed on the roots 52, and then the thin metal wires 6 are wound and fixed on the outer surfaces of the spiral sections 2-2 of the thin tooth piles 2 to form a pile frame 3.
