Detailed Description

The technical solution of the present invention is further described in detail by the accompanying drawings and embodiments.

The invention is inspired by minimally invasive surgery, the minimally invasive surgery can be performed only by forming a small hole on the body and the chest and abdomen, and the invention has the great advantage of small damage to the human body. Therefore, the invention adopts the prior art that the fine holes are drilled on the broken teeth, the tooth roots and even the gums, namely the tooth bones, and the fine holes are drilled, so that the dental implant of the invention can be implemented on the broken teeth, the tooth roots and the tooth bones, and the dental implant can be implemented without tooth extraction at all and after several months.

The invention is also inspired by construction in the construction industry, and in the construction industry, on the basis of a house which is provided with reinforced cement, even if a period of time passes, days and months, the reinforced cement can still be welded upwards on the basis, the cement is poured continuously, and the building construction is continued. Therefore, the thin dental pile of the invention is equivalent to a steel bar, the filling agent is equivalent to cement, the broken tooth with the thin dental pile installed, or the tooth root, or the tooth bone is equivalent to the foundation of the steel bar cement, the broken tooth, the tooth root, or the tooth bone are firmly bonded together by the filling agent with strong bonding force to form a new dental pile with enough strength, and the dental crown is installed on the new dental pile, thus completing the dental implant of the invention.

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 holes 1, preferably between 2 mm and 5 mm, may be any depth, depending on the actual situation, for example between 7 and 15 mm, even if they are driven into the root 52, and is usually 3 to 5 mm. Due to the fine holes, the two fine holes 1 are spaced by 3, 4 mm, even 5,6 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, and it is explained that 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 like an acupuncture needle. The lower part of the spiral section 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 rod and a wire is wound around the outside of the round rod. 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 piles 2 in the present invention are hard enough like steel needles and do not break. The insertion section 2-1 is constructed in a needle-like thin round rod structure, and the thickness and length of the insertion section are matched with those of the fine hole 1, and the insertion section can be inserted into the fine hole 1 relatively tightly, preferably with a diameter of 0.1 to 0.6 mm. Instead of a round rod, a column may be used, and various shapes such as a hexagonal rod, an octagonal rod, and the like may be used as long as the rod can be tightly inserted into the inside of the pore 1. Since an adhesive is used during the insertion, a cylinder of a hexagonal, octagonal, etc. shape, which is used to fix the stud 2 to the wall of the hole 1, can receive 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 fitted over the broken tooth 51, it is shorter, about 3 to 4 mm in height, about 3 to 6 mm in length, about 15 to 16 mm in length, if it is fitted over the tooth root 52. 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 thin dental pile 2, which is characterized in that the upper spiral section 2-2 is constructed as a cylinder having a central axis, and the central axis is provided with a plurality of support bars extending up and down to fix the cylinder, 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 both inside and outside the cylinder.

Fig. 6 shows a fine dental pile 2 in the form of a straight round bar, in which shallow micro-pits 7 are formed on the surface thereof, for example, by laser drilling, which does not affect the rigidity and strength of the fine dental pile 2, but the micro-pits 7 can contain a small amount of filler 4 therein 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 0.4 mm in diameter, 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.

Fig. 9 is a schematic view of an embodiment of a different structure of the fine tooth post 2. The insertion section 2-1 is a round bar, for example, 0.4 mm in diameter, while the screw section 2-2 is a bottomed cylinder structure, the upper end of the insertion section 2-1 is attached to the center of the bottom of the cylinder, the diameter of the cylinder is, for example, 2 to 3 mm, and the wall thickness is, for example, 0.3 mm. This structure can contain more filler 4.

Fig. 10 is a schematic view showing another different structure of the fine dental pile 2, in which the upper and lower structures are a circular rod, the spiral section 2-2 is formed by making four pieces in a transverse cross direction from the circular rod, and the four pieces are fixed on the circular rod of the central shaft to form an integral rigid structure.

Fig. 11 is a schematic view of another example of the fine tooth pile 2, in which a spiral portion 2-2 is in the shape of a paper clip. The structure is like a paper clip.

Fig. 12 is a view in which a fine wire 6 is wound and fixed to the outside of the spiral section 2-2 of 2 fine dental piles 2 to form a dental pile frame 3 in order to reinforce the rigidity of two separately used fine dental piles 2 and to increase the contact area with the filler 4.

Fig. 13 is a schematic view of an embodiment in which three dental piles 2 are used and a dental pile frame 3 is formed by winding and fixing a thin metal wire 6. This further enhances the stiffness of the entire structure, increasing the contact area with the filler 4.

Fig. 14 is a schematic view of an embodiment in which one thin tooth pile 2 is attached to a tooth 51. The root 52 is arranged under the broken tooth 51, after the adhesive is coated on the insertion section 2-1 of the fine tooth pile 2, the fine tooth pile 2 is inserted into the drilled fine hole 1 on the broken tooth 51, so that the fine tooth pile 2 and the broken tooth 51 are firmly integrated. 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.

The above-mentioned fine dental piles 2 are all prefabricated and are used by the doctor. The dental pile frame 3 may be formed by winding and fixing the fine metal wire 6 for clinical use of the fine dental pile 2 in practice, may be formed by mechanical fixing, laser fixing, or may be pre-manufactured and selected by a doctor.

Fig. 17 is a schematic view of an embodiment in which a filler 4 is added to the embodiment of fig. 12. The filler 4 may be any suitable filler available at present and may be selected. The filling agent 4 may be injected, applied, sprayed, etc. into and out of the thin stump 2 to form a hard whole with the fractured tooth 51, and the place where the crown 5 is installed may be made into a predetermined configuration such as a mountain shape, a steamed bun shape, etc. so as to install the crown 5 thereon. The filling agent 4 is usually thick and can be filled by direct injection or coating, or like cement pouring in the construction industry, the periphery of the filling agent is limited by a template and is placed around the thin dental pile 2, after the filling agent 4 is filled, the template is removed and then is trimmed to be repaired into a shape convenient for placing the dental crown 5. This is what any dentist will do.

In the period of the Titan Tang in ancient China, the technology of inserting and filling teeth is developed equivalently, and the new herbal remedies are written in the book, and amalgam mainly containing silver and tin is recorded as a filling material for tooth restoration. Mercury is now used only sparingly because of its toxicity. It is still a filler 4.

The invention also proposes a filler 4 comprising a plurality of metal balls having a diameter of 0.5 to 1 mm, and a binder. The filler 4 is formed by mixing the metal balls and the binder. The filler may also include an accelerator to adjust the rate at which the filler sets. The metal balls may be stainless steel balls, or other alloy metal balls.

Fig. 18 is a schematic view of the construction of a dental implant according to the invention, comprising a root 52, a post 2, an extender 4, a crown 5. A fine hole 1 is drilled on a tooth root 52, a fine tooth post 2 is installed in a bonding mode, a filling agent 4 is added, a tooth crown 5 is installed in a bonding mode, and the dental implant is completed. The crown 5 may be any crown known in the art, such as a porcelain crown, a stainless steel crown, or the like.

The dental implant of the present invention is mounted on the root 53 of the broken tooth 51, and has the same structure as that of the present example.

The embodiment shown in fig. 19 is intended to use the filling agent 4 together with the crown 5, and the filling agent 4 is first filled into the crown 5, and directly and together mounted on the thin stump 2, and directly bonded with the broken tooth 51, the tooth root 52, or the tooth bone 53, to complete the dental implant of the present invention.

Since the tooth itself has a size of only a few millimeters in length, width and height, the fine tooth post 2 of the present invention is also a small-sized member, and generally has a total length of not more than a few millimeters to about ten and several millimeters, and it is easy to perform such a dental implant.

The invention can greatly expand the applicable population of the dental implant, and can easily implement the dental implant of the invention by a large number of people with broken teeth, and even people without tooth roots, thereby greatly improving the quality of life.
