Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, and more specifically, to a probe for measuring the thickness of dental implant bone. Background Technology
[0002] In dental restoration, dental implants require obtaining the distance (i.e., bone thickness) from the alveolar bone preparation cavity to the adjacent bone surface to provide a reference for subsequent surgical procedures. Currently, CT (Computed Tomography) scans are commonly used for measurement. However, CT scans involve radiation, and to avoid affecting the patient's health, continuous or repeated imaging is not possible. Furthermore, CT scans are complex to operate and costly, failing to meet the need for rapid and repeated measurements. Utility Model Content
[0003] The purpose of this invention is to provide a dental implant bone thickness measurement probe, which has a simple structure, simplifies the operation of measuring bone thickness, improves measurement efficiency, and enables repeatable and rapid measurement.
[0004] A dental implant bone thickness measuring probe includes a rod and a metal sheet, one end of the rod being formed as a connecting end, the metal sheet being connected to the connecting end, the rod being used to insert into a cavity in the alveolar bone, and the metal sheet being configured to be flexible for conforming to at least one side of the alveolar bone surface where the cavity is located to measure the distance between the cavity and the bone surface.
[0005] In the above technical solution, the rod can be inserted into a pre-drilled hole in the alveolar bone to locate and form a measurement reference point. Then, the metal sheet is bent to deform and fit against one side of the alveolar bone where the hole is located. After completion, the rod and the metal sheet are removed together. The distance between the circumference of the rod and the metal sheet is then measured using an existing length measuring tool to obtain the bone thickness corresponding to the hole. The overall operation is simple, effectively simplifying the measurement steps and improving measurement efficiency. Moreover, the measurement can be repeated simply by replacing the metal sheet, reducing measurement costs and increasing measurement flexibility.
[0006] Furthermore, the connecting end is provided with a fixing member for fixing the metal sheet, the connecting end forms a support surface, the middle of the support surface extends along the axial direction of the rod to form a connecting shaft, the fixing member is detachably sleeved on the connecting shaft, and the metal sheet is sandwiched between the fixing member and the support surface.
[0007] In the above technical solution, the fastener and the support surface cooperate to clamp and fix the metal sheet, preventing the metal sheet from shifting during measurement; the detachable connection structure facilitates the replacement or sterilization of the metal sheet, improving the reusability of the instrument.
[0008] Furthermore, the fastener is provided with a connecting hole, through which the connecting shaft passes and is interference-fitted with the fastener.
[0009] In the above technical solution, the connecting shaft and the fixing component are interference-fitted, which allows the fixing component to be quickly assembled and disassembled without auxiliary tools. The friction generated by the interference fit can keep the fixing component stable and avoid measurement errors caused by loosening.
[0010] Furthermore, the metal sheet has a through hole corresponding to the connecting shaft, and the connecting shaft passes through the through hole.
[0011] In the above technical solution, the metal sheet is connected to the connecting shaft through a through hole, thereby forming a limit and improving the measurement stability. At the same time, it ensures that the metal sheet can rotate around the connecting shaft, making it convenient to adjust the angle of the metal sheet.
[0012] Furthermore, the surface of the metal sheet is smooth.
[0013] In the above technical solution, the smooth surface can reduce the friction between the metal sheet and the oral cavity, which not only protects the patient's oral cavity from scratches, but also enhances the conformity of the sheet in the moist oral environment.
[0014] Furthermore, the end of the rod away from the metal sheet is formed into a cone shape.
[0015] In the above technical solution, the tapered end structure reduces the resistance when the rod is inserted into the prepared hole, guides the instrument to be accurately positioned, and improves the smoothness and safety of the operation.
[0016] Furthermore, the circumferential surface of the rod is provided with a plurality of marking rings, which are arranged at equal intervals along the axial direction of the rod.
[0017] In the above technical solution, the equidistant marking rings form a visual scale on the surface of the rod, which makes it convenient for doctors to measure the bone thickness data corresponding to different depths of the prepared hole.
[0018] Furthermore, both the rod and the metal sheet are made of titanium.
[0019] In the above technical solution, titanium metal can meet the strength requirements of the rod, and the use of titanium metal in the metal sheet allows it to bend and deform while having a certain degree of elasticity, thus meeting the measurement requirements.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: the rod can be inserted into a pre-drilled hole in the alveolar bone to locate and form a measurement reference point. Then, the metal sheet is bent to deform and fit against one side of the alveolar bone surface where the hole is located. After completion, the rod and the metal sheet are removed together. The distance between the circumference of the rod and the metal sheet is measured by existing length measuring tools to obtain the bone thickness corresponding to the hole. The overall operation is simple, effectively simplifying the measurement steps and improving measurement efficiency. Moreover, the measurement can be repeated by simply replacing the metal sheet, reducing measurement costs and improving measurement flexibility. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0028] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0029] This invention provides a dental implant bone thickness measurement probe for measuring the bone thickness of dental implants. It should be noted that during the implantation process, it is necessary to measure the bone thickness from the prepared cavity to both sides of the bone surface. Based on the bone thickness data, the dentist determines the specific surgical procedure. For example, if the bone thickness meets the requirements, the dentist can perform operations such as grinding and drilling on the corresponding side; if the bone thickness on one side is too small, the dentist can choose to operate from the other side.
[0030] Please refer to Figures 1 to 4 In a preferred embodiment, the dental implant bone thickness measuring probe of the present invention mainly includes a rod 1 and a metal sheet 2. One end of the rod 1 is formed as a connecting end 11, and the metal sheet 2 is connected to the connecting end 11. The rod 1 is used to insert into a cavity in the alveolar bone, and the metal sheet 2 is configured to be flexible and used to conform to at least one side of the alveolar bone surface where the cavity is located, so as to measure the distance between the cavity and the bone surface.
[0031] It should be noted that the pre-drilled cavity is a hole drilled into the alveolar bone for dental implantation. The rod 1 is cylindrical, with one end inserted into the cavity to establish a measurement reference point. At this point, the metal sheet 2 is positioned above the cavity. The metal sheet 2 is then bent, deforming it and fitting it to one side of the alveolar bone where the cavity is located. After completion, rod 1 and metal sheet 2 are removed together. The distance between the circumference of rod 1 and metal sheet 2 is then measured using existing length measuring tools, such as calipers, to determine the bone thickness corresponding to the cavity. Figure 4 As shown, after removing rod 1, d1, d2, d3, and d4 represent the bone thickness corresponding to different depths of the prepared hole. This invention is simple to operate, effectively simplifying the measurement steps and improving measurement efficiency. Furthermore, it only requires replacing the metal sheet 2 for repeated measurements, reducing measurement costs and enhancing measurement flexibility.
[0032] In this embodiment, the connecting end 11 is provided with a fixing member 3 for fixing the metal sheet 2. The connecting end 11 forms a support surface 12, and the middle of the support surface 12 extends along the axial direction of the rod body 1 to form a connecting shaft 13. The fixing member 3 is detachably sleeved on the connecting shaft 13, and the metal sheet 2 is clamped between the fixing member 3 and the support surface 12. The fixing member 3 and the support surface 12 cooperate to clamp and fix the metal sheet 2, preventing the metal sheet 2 from shifting during measurement. The detachable connection structure facilitates the replacement or sterilization of the metal sheet 2, improving the reusability of the instrument.
[0033] The fastener 3 has a connecting hole 31, through which the connecting shaft 13 passes and is interference-fitted with the fastener 3. For example, the connecting hole 31 is located in the middle of the fastener 3 and extends through it. The fastener 3 can be interference-fitted with the connecting shaft 13 through the connecting hole 31, thereby clamping the metal sheet 2 between the fastener 3 and the support surface 12. The interference fit between the connecting shaft 13 and the fastener 3 allows the fastener 3 to be quickly assembled and disassembled without auxiliary tools, and the friction generated by the interference fit maintains the stability of the fastener 3, avoiding measurement errors caused by loosening.
[0034] The metal sheet 2 has a through hole 21 corresponding to the connecting shaft 13, and the connecting shaft 13 passes through the through hole 21. The metal sheet 2 is connected to the connecting shaft 13 through the through hole 21, thereby forming a limit and improving the measurement stability. At the same time, it ensures that the metal sheet 2 can rotate around the connecting shaft 13 as an axis, which facilitates the adjustment of the angle of the metal sheet 2.
[0035] In this embodiment, one end of the metal sheet 2 is connected to the connecting shaft 13, and the other end extends outward to form a bendable measuring end to measure the distance between one of the alveolar bone surfaces and the cavity. In other possible embodiments, the metal sheet 2 can be formed with the middle connected to the connecting shaft 13 and both ends extending outward to form connecting ends 11. The distance between the two bone surfaces and the cavity can be measured simultaneously through the two connecting ends 11, further improving the measurement efficiency.
[0036] In this embodiment, the surface of the metal sheet 2 is smooth. The smooth surface reduces the friction between the metal sheet 2 and the oral cavity, protecting the patient's oral cavity from scratches and enhancing the sheet's conformability in the moist oral environment.
[0037] The end of the rod 1 furthest from the metal sheet 2 is tapered. The tapered end structure reduces the resistance when the rod 1 is inserted into the prepared hole, guides the instrument into precise positioning, and improves the smoothness and safety of the operation.
[0038] The circumferential surface of the rod 1 is provided with several marking rings 14, which are arranged at equal intervals along the axial direction of the rod 1. The equidistant marking rings 14 form a visual scale on the surface of the rod 1, which facilitates the doctor to measure the bone thickness data corresponding to different depths of the prepared hole.
[0039] Both the rod 1 and the metal sheet 2 are made of titanium. Titanium provides the strength required for the rod 1, while the use of titanium in the metal sheet 2 allows it to bend and deform while maintaining a certain degree of elasticity, thus meeting the measurement requirements.
