Description

Technical Field

[0001] The present invention relates to a root implant structure for dental implant surgery, and more particularly to a root implant structure that can increase the surface area contact and force when entering the alveolar bone, making the root implant more stable and thus improving the strength of the root implant. Background Art

[0002] Dental implant is a treatment process that replaces the tooth root with an artificial root implant to compensate for tooth loss. In the dental implant process, first, an artificial metal root implant is implanted into the alveolar bone as a stable base. After the bone grows to cover the artificial root implant, when it is confirmed that the root implant is tightly combined with the bone, a crown can be connected to the upper connecting kit to complete the dental implant process. The root implant of a common dental implant surgery penetrates the gum, so a small hole will be drilled in the bone of the gum in advance to insert and fix the root implant. After a period of time, the bone of the gum will proliferate, so that the root implant can be firmly fixed on the gum.

[0003] The structure of a general root implant generally includes the following steps:

[0004] 1. Before dental implant, the doctor will first check the patient's teeth, oral cavity, and physical health status and customize a suitable dental implant plan.

[0005] 2. Incise the dental implant position (the upper jaw bone or the lower jaw bone in the oral cavity), and drill a dental hole for dental implant in the alveolar bone at that place.

[0006] 3. Lock the root implant (artificial tooth root) into the dental hole and ensure it is fixed in the correct position. Wait for the bone to grow and heal to cover the implant instead of the extracted tooth root.

[0007] 4. Confirm that the alveolar bone is firmly combined with the implant. Lock a " abutment tooth" (also known as a dental post) on the root implant to support the denture to be installed later.

[0008] 5. Lock the denture onto the abutment tooth, fine-tune and confirm to complete the dental implant process.

[0009] In the aforementioned dental implant process, the artificial root implant is screwed into the alveolar bone by the provided thread to fix the root implant in the alveolar bone, and the gum covers the end of the artificial root. After the alveolar bone grows through a period of osseointegration to initially stabilize the artificial root, the gum at the end of the artificial root is then incised to combine the abutment at the end of the artificial root. However, only relying on the contact between the thread of the artificial root implant and the alveolar bone to fix the artificial root implant, since the contact area is limited, the supporting force of the alveolar bone on the artificial root implant may also be limited, which is likely to lead to poor initial stability of the artificial root implant and cause the overall failure of the dental implant surgery.

[0010] In view of this, through continuous research and experiments, the inventor of this case came up with the idea of designing a root implant structure for dental implant surgery, so as to improve the stability and strength of the root implant when it enters and locks into the alveolar bone. Summary of the Invention

[0011] The main object of the present invention is to provide a root implant structure for dental implant surgery, so that when the root implant enters the alveolar bone, the contact area and force can be increased, making the root implant more stable when locked into the alveolar bone, thereby improving the strength of the root implant and facilitating subsequent dental implant surgery.

[0012] The present invention provides a root implant structure for dental implant surgery, which is provided with an implant body. The implant body includes a head section for applying force to the root implant, a first helical section and a second helical section extending along the longitudinal axis of the implant body from the head section, and a third helical section extending along the longitudinal axis of the implant body from the second helical section and being tapered. Among them, the first helical section has fine-pitch threads and is composed of a plurality of teeth arranged at intervals; the second helical section and the third helical section have coarse-pitch threads and are composed of a plurality of teeth arranged at intervals; the third helical section is arranged in a cross-shaped radial pattern along the transverse axis of the implant body. Its characteristics are as follows:

[0013] The interval sections of each tooth of the second helical section and the third helical section are respectively provided with recessed grooves.

[0014] The groove is recessed inward by the upper inclined surface and the lower inclined surface of the interval section to form a triangular groove body.

[0015] The upper edge and the lower edge of the teeth of the second helical section and the third helical section are respectively set as inclined sections towards the end.

[0016] The front edge of the teeth of the second helical section and the third helical section is a vertical cross-section.

[0017] The third helical section is provided with four right-angled cutting grooves.

[0018] Thereby, when the root implant enters the alveolar bone, the contact area and force can be increased, making the root implant more stable, and thus improving the strength of the root implant. Brief Description of the Drawings

Detailed implementation mode

[0024] Please refer to Figure 1 and Figure 2 simultaneously, which is the perspective view of the present invention. As shown in the figure, the present invention provides a root implant structure for dental implant surgery, provided with an implant body 1, the implant body 1 includes a head section 11 for applying force to the implant body 1, a first helical section 12 and a second helical section 13 extending along the longitudinal axis of the implant body 1 from the head section 11, and a third helical section 14 extending along the longitudinal axis of the implant body 1 from the second helical section 13 and being tapered. Among them, the inner edge of the head section 11 is provided with a tool embedding section 111 generally in a hexagonal shape, and the tool embedding section 111 can be used to cooperate with a tool to screw the implant body 1 into the alveolar bone, and can also serve as a abutment for assembling an artificial dental crown.

[0025] The first helical section 12 has relatively dense fine-threaded threads, and is provided with a plurality of semi-circular grooves 121 arranged at intervals, and the plurality of semi-circular grooves are used to form a plurality of tooth portions 122 arranged at intervals.

[0026] The second helical section 13 has relatively sparse coarse-threaded threads and is composed of a plurality of tooth portions 131 arranged at intervals. The upper edge and the lower edge of the tooth portions 131 are respectively provided with an upper inclined section 132 and a lower inclined section 133 that are appropriately inclined towards the end, the front edge is provided with a vertical cross section 134, and a recessed groove 135 is provided at the interval section between the tooth portions 131.

[0027] The third helical section 14 has relatively sparse coarse-threaded threads and is composed of a plurality of tooth portions 141 arranged at intervals. It is provided with four right-angled cutting grooves 142, so that the third helical section 14 is arranged in a generally cross-shaped radial pattern along the transverse axis of the implant body 1. A sharp cutting bottom end is formed by the four cutting grooves 142, thereby forming a self-tapping root implant to facilitate cutting into the patient's alveolar bone during dental implant surgery; the upper edge and the lower edge of the tooth portions 141 of the third helical section 14 are respectively provided with an upper inclined section 143 and a lower inclined section 144 that are appropriately inclined towards the end, the front edge is provided with a vertical cross section 145, and a recessed groove 146 is provided at the interval section between the tooth portions 141.

[0028] In this embodiment, the grooves 135 and 146 formed in the spacer sections between the teeth 131 and 141 of the second helical section 13 and the third helical section 14 are formed by inwardly concave upper and lower inclined surfaces in the spacer sections to form a generally triangular groove body.

[0029] By means of the aforementioned components, a dental implant root implant is formed. When the dental implant root implant enters the alveolar bone during the dental implant surgery, the upper inclined sections 132 and 143 and the lower inclined sections 133 and 144 at the upper and lower edges of the second helical section 13 and the third helical section 14, as well as the grooves 135 and 146 formed in the spacer sections between the teeth 131 and 141, can increase the surface area contact and force application, making the dental implant root implant more stable after being locked into the alveolar bone, thereby improving the strength of the dental implant root implant and facilitating the subsequent dental implant surgery.

[0030] Please refer to Figure 3 , which is a partial cross-sectional view of the present invention. As shown in the figure, in the preferred implementation state of the present invention, the second helical section 13 is provided as hollow, and an internal thread 136 is provided on the inner edge of the hollow section to facilitate the cooperation with different types of tools to screw the implant body 1 into the alveolar bone. The third helical section 14 is solid to improve the strength of the third helical section 14 and the entire dental implant root implant, thereby facilitating the entry into the alveolar bone. When the dental implant root implant is locked into the alveolar bone, the dental implant root implant can be more easily screwed into and fixed in the alveolar bone. And when the dental implant root implant is fixed in the alveolar bone, the adhesion between the dental implant root implant and the alveolar bone can be effectively improved, so that the dental implant root implant will not easily be unscrewed and loosened from the alveolar bone.

[0031] Please refer to Figure 5 , which is a bottom view of the present invention. As shown in the figure, the third helical section 14 of the present invention is provided with four right-angled cutting grooves 142, which are arranged in a generally cross-shaped radial pattern along the transverse axis of the implant body 1. By means of the four cutting grooves 142, a sharp cutting bottom end is formed. During the dental implant process, first drill a hole in the alveolar bone, and then screw the dental implant root implant into the alveolar bone. With the self-tapping root design of the cutting grooves 142, the sharp cutting bottom end can be directly used to cut the alveolar bone and screw it in, avoiding the trouble of prior tapping. And the cut bone chips can be concentrated in the depressions formed by the cutting grooves 142, and the dental implant root implant can be more firmly combined with the alveolar bone.

[0032] In the actual application of the present invention, since the dental implant root implant is designed in a tapered shape with a narrower bottom and a wider top, and the grooves 135 and 146 are provided in the spacer sections between the teeth 131 and 141 of the second helical section 13 and the third helical section 14, the alveolar bone can be clamped against the depressions of the grooves 135 and 146, increasing the adhesion between the dental implant root implant and the alveolar bone, and further improving the bonding reliability between the dental implant root implant and the alveolar bone.

[0033] The foregoing embodiments are only illustrative of the preferred embodiments of the present invention and do not limit the patent scope of the present invention. Any minor modifications or changes still fall within the gist of the present invention and do not depart from the spirit of the present invention.

[0034] In summary, the present invention provides a dental implant structure for dental implantation surgery, which is composed of an implant body provided with first, second, and third thread segments, and grooves provided at intervals between the teeth of the second and third thread segments. When the dental implant enters the alveolar bone, the surface area of contact and stress can be increased, so that the dental implant can be locked in the alveolar bone more firmly, thereby improving the strength of the dental implant, which is conducive to subsequent dental implantation surgery.
