Description

Immediately implanted dental structure

This creation is about a dental implant structure, especially a specially designed dental implant structure.

The growth of the teeth is divided into two stages. In the first stage, the baby teeth are started, and in the second stage, the deciduous teeth begin to fall off, and the permanent teeth that are harder than the deciduous teeth will grow. (permanent teeth), in which, after the permanent teeth grow out, no new teeth will grow, and when the permanent teeth have serious defects (for example, cavities, permanent teeth fractures), only the defects of the permanent teeth can be performed. Repair or remove the entire permanent tooth, and the damaged permanent tooth or the removal of the permanent tooth will not only cause the appearance of the tooth to be unsightly, but also cause the dislocation of the surrounding tooth, in the event of tooth dislocation. It can lead to malocclusion, which makes chewing and speaking more and more difficult. However, in order to avoid the occurrence of tooth dislocation, many patients often turn to the dentist for repairing defective teeth.

In addition, as the technique of repairing teeth changes with each passing day, some patients will repair the defective teeth by artificial implants. In the case of artificial implants, a drill bit is drilled on the patient's alveolar bone. The hole is cut, and the implant body is implanted into the inside of the cut hole, so that a part of the implant body is located inside the cut hole, and the remaining part of the implant body is convexly protruded to the cut hole to install the artificial crown.

However, in order to prevent the rat implant from being punctured when it is inserted into the cut hole, the dentist usually selects a drill of a suitable size according to the size of the implant and the size of the implant, thereby forming an appropriately sized cut hole in the alveolar bone. However, if the size of the cut hole is too large, the implant will be shaken when it is implanted into the cut hole, and the dentist must take extra time to put the filler into the cut hole in order to make the implant body stable inside the cut hole. Therefore, the operation time of implanting the implant into the alveolar bone will be lengthened. On the contrary, when the size of the cut hole is too small, a large amount of bone fragments will be generated during the implantation of the implanted body, resulting in implants. The experience is difficult to implant inside the cut hole, and the working time of implanting the alveolar bone relative to the implant body becomes longer.

The main purpose of this creation is that the dental implant structure can be directly implanted into the alveolar bone to achieve the effect of shortening the working time, and can effectively discharge excess bone during the implantation of the dental implant structure into the alveolar bone. The swarf enables the intimate joint between the alveolar bone and the implant structure to ensure that the implant structure does not sway, thereby improving the success rate of the operation.

In order to achieve the above purpose, the present invention relates to a ready-to-plant dental implant structure, wherein the above-mentioned ready-to-plant dental implant structure is directly implanted into an alveolar bone, and is mainly composed of a dental implant body and a plurality of groovings. The implant body has a dental implant portion and is spirally fitted to the alveolar bone through a threaded portion formed on a periphery of the dental implant portion, and one end of the dental implant portion extends to form a tapered pusher portion.

Each of the slits has a first slit, a second slit and a turning point, and the first slit is located at a periphery of the pushing portion, and is simultaneously formed on the dental implant portion, the pushing portion and the thread And the second cutting slot is located at a periphery of the dental implant portion and is formed at the dental implant portion and the thread portion, wherein the turning portion is used to change the grooving trajectory, and is located at the first grooving and the first Between the two slots, the grooving trajectory of the first grooving is different from the grooving trajectory of the second slot.

Wherein the threaded portion has a thick thread close to the pushing portion and a fine thread away from the pushing portion, the coarse thread has a pitch larger than the fine thread, and the slit extends from the pushing portion to the The overall length of the thick thread is such that a partial section of the slit can be formed on a partial length of the fine thread, or the slit extends from the pushing portion to an overall length of the fine thread, and the center of the pushing portion Forming a first thrust surface, and forming a second thrust surface having a curvature different from the first thrust surface on a periphery of the first thrust surface, and the second thrust surface has the first slot In a preferred embodiment, the plurality of slits are annularly arranged on the outer periphery of the ejector portion such that the ejector portion has a cross shape.

Furthermore, the average slope of the first slit is smaller than the average slope of the second slit, such that the second slit is nearly parallel to the periphery of the dental implant portion, and each of the first slits is away from the second portion. One end of the grooving joint forms a ring of an outer ring having an outer diameter smaller than the outer periphery of the dental implant portion, and the abutting ring is located at a center of the pushing portion. In a preferred embodiment, the diameter of the abutting ring is less than 2 mm.

Furthermore, the first slit has a first cutting surface and a first deposition surface adjacent to the first cutting surface, and the second slit has a second cutting adjacent to the first cutting surface And a second stacking surface adjacent to the second cutting surface, an acute angle is formed between the first cutting surface and the second cutting surface and the outer surface of the thread portion, and the first stacking surface and the first stacking surface Forming an obtuse angle between the two deposition surfaces and the outer surface of the threaded portion, and a side of the first cutting surface not connected to the first deposition surface and the first deposition surface not connected to the first cutting surface Forming a first width between the sides, and forming a width smaller than the first width between a side of the second cutting surface not connected to the second stacking surface and a side of the second stacking surface not connected to the second cutting surface The second width.

It can be seen from the foregoing description that the present invention is characterized in that the end portion of the dental implant structure is provided with a ejector portion having a tapered appearance, so that the dental implant structure can be directly implanted into the alveolar bone, and the dental implant structure has two different paths. The grooving of the trajectory causes the excess bone fragments to be automatically discharged through the two groovings during the implantation of the dental implant structure, and the bone fragments generated by implanting the dental implant structure into the alveolar bone can be implanted. The dental structure is tightly coupled to the alveolar bone, thereby not only shortening the operation time of implanting the dental implant structure, but also ensuring that the dental implant structure does not sway, and significantly improving the safety and stability of the implant.

In order to further understand the structure, use and characteristics of this creation, we have a deeper and clearer understanding and understanding. The preferred embodiment is described below with reference to the following:

Referring to FIG. 1 to FIG. 3, in the first preferred embodiment, the present invention provides a dental implant structure 1 for assembling an artificial crown (not shown), and is mainly composed of a dental implant body 10 and A plurality of slots 20 are formed.

The first implant post 111 is recessed toward the second implant post 112 at a center away from the second implant post 112. Connected to the connecting hole 113 of the artificial crown, and the second implant 112 is tapered away from the first implant 111 in a direction away from the first implant 111 to form a tapered push. In addition, the center of the ejector portion 12 forms a first thrust surface 121 that is not connected to the dental implant portion 11, and forms a curvature different from the first thrust surface 121 at the periphery of the first thrust surface 121. The second thrust surface 122 is pushed, and the second thrust curved surface 122 is connected to the dental implant portion 11.

A plurality of slots 20 are annularly equidistantly arranged on the outer peripheral side of the implant body 10. As shown, each slot 20 has a first slot 21 and a second slot on the side of the first slot 21 The groove 22, the first slit 21 is formed by the second pushing surface 122 of the pushing portion 12 extending along the first path P1 around the implant body 10 so that the first slit 21 is located at the pushing portion. The outer periphery of 12, and then the first slot 21 is transmitted through the first path P1 to generate a first average slope S1. In this embodiment, the first slot 21 is simultaneously formed on the second implant column of the implant portion 11. 112, the pushing portion 12 and the thread portion 13.

The second slot 22 of the slot 20 is formed by a recessed extension of one end of the first slot 21 along a second path P2 different from the first path P1, such that the first slot 21 and the second slot 22 The second slot 22 is located at the periphery of the implant portion 11 and passes through the second path P2 to form a second average slope S2. Thereby, the slot 20 extends from the jacking portion 12 to the thick thread 132. The overall length is such that the slit 20 is not formed on the periphery of the first implant column 111. However, the slit 20 is not formed on the outer periphery of the first implant column 111 for convenience of explanation, that is, as shown in FIG. In the case where the slit 20 extends to the entire length of the thick thread 132, a partial section of the slit 20 may extend to a partial length of the fine thread 131 such that the remaining length of the fine thread 131 does not form the slit 20.

In this embodiment, the second slot 22 is simultaneously formed on the second implant post 112 and the threaded portion 13 of the implant portion 11, wherein the slot 20 is in both the first slot 21 and the second slot 22 The connected places form a turning point 23 which changes the grooving trajectory, whereby since the grooving 20 has the turning point 23, the grooving trajectory of the first grooving 21 is different from the kerf trajectory of the second slit 22.

Furthermore, both the first path P1 and the second path P2 are spiraled such that both the first slot 21 and the second slot 22 assume a spiral shape, and the first slot 21 of the spiral-like state is present. The pitch is smaller than the pitch of the second slot 22 exhibiting a spiral pattern such that the first average slope S1 is less than the second average slope S2, thereby making the second slot 22 nearly parallel to the periphery of the implant portion 11.

Referring to FIG. 5, the first slot 21 of each slot 20 is formed at an end away from the second slot 22 to form a ring ring 24 having an outer diameter smaller than the periphery of the dental implant portion 11. The ring 24 is located at the center of the pushing portion 12 such that the first pushing curved surface 121 is located inside the ring 24, and in this embodiment, the diameter of the ring 24 is less than 2 mm, and as shown, The artificial implant structure 1 has four slits 20, and the four slits 20 are annularly arranged equidistantly on the periphery of the implant body 10 such that the four first slits 21 are distributed at the four oblique angles of the thrust portion 12. The position, in turn, causes the appearance of the urging portion 12 to assume a cross shape.

Referring to FIG. 6 , the first cutting groove 21 has a first cutting surface 211 and a first deposition surface 212 . The first cutting surface 211 and the first deposition surface are adjacent to each other such that the first cutting surface 211 intersects with the first cutting surface 211 . A stacking surface 212 further forms a first angle 213 between the first cutting surface 211 and the first stacking surface 212, wherein the first cutting surface 211 forms an angle of less than 90 degrees with the outer surface of the threaded portion 13. a first acute angle 214, and a first obtuse angle 215 greater than 90 degrees is formed between the first accumulation surface 212 and the outer surface of the threaded portion 13, and the first cutting surface 211 is not connected to the side of the first accumulation surface 212. A first width 216 is formed between the side of the first deposition surface 212 that is not connected to the first cutting surface 211.

Referring to FIG. 7, the second slot 22 has a second cutting surface 221 connected to the first cutting surface 211 and a second stacking surface 222 connected to the first stacking surface 212. The second cutting surface 221 Adjacent to the second stacking surface 222, the second cutting surface 221 and the second stacking surface 222 intersect with each other, thereby forming a second angle 223 between the second cutting surface 221 and the second stacking surface 222, wherein a second acute angle 224 of less than 90 degrees is formed between the second cutting surface 221 and the outer surface of the threaded portion 13, and a second obtuse angle greater than 90 degrees is formed between the second deposition surface 222 and the outer surface of the threaded portion 13. 225, and a second width of the first cutting surface 221 not connected to the second stacking surface 222 and a side of the second stacking surface 222 not connected to the second cutting surface 221 is formed to have a width smaller than the first width 216 226, whereby the width of the first slit 21 is greater than the width of the second slit 22.

Referring to FIG. 8 , in a specific application, since the dental implant structure 1 has a ejector portion 12 having a tapered shape at one end, the dental implant structure 1 can be directly implanted into the alveolar bone 30, and the dental implant structure 1 During the implantation into the alveolar bone 30, the alveolar bone 30 can penetrate through the implant structure 1 to form a cut hole (not shown) corresponding to the shape of the dental implant structure 1 and simultaneously produce a bone 31. The bone chips 31 are discharged along the first slit 21 and through the second slit 22 to the outside of the cut hole (not shown), wherein when the implant body 10 is implanted into the alveolar bone 30, The width of all the grooves 21 is larger than the width of the second slits 22, so that the first slits 21 can accommodate most of the bone chips 31, and the chance of moving the bone chips 31 between the two threads of the coarse threads 132 is reduced. When the bone chips 31 move to the inside of the second slit 22, since the width of the second slit 22 is smaller than the width of the first slit 21, the moving speed of the bone chips 31 is accelerated, thereby allowing the bone chips 31 to be cut. The inside of the hole (not shown) is quickly discharged to the inside of the patient's mouth, so that the inside of the cut hole (not shown) does not accumulate excessive bone chips 31, the dentist does not It takes too much effort to directly implant the dental implant structure 1 into the alveolar bone 30, whereby the dental structure 1 is easy to be implanted into the dental bone 30, removes the bone debris 31, removes the bone debris 31, and is tight. Combined with four major functions such as dental bone 30.
