Description

Technical Field

[0001] This utility model relates to dental implant auxiliary tools, and more particularly to a simple dental implant preparation direction guide clip. Background Technology

[0002] In dental implant surgery, stable integration between the implant and alveolar bone is a core prerequisite for ensuring implant success and long-term use. The precision of alveolar bone drilling directly determines the implant placement, angle, and subsequent osseointegration quality. Furthermore, after implantation, the following requirements must be met: the distance between the mesial and distal alveolar bone and adjacent natural teeth must be at least 1.5 mm, and the thickness of the buccal and lingual alveolar bone must be at least 1 mm.

[0003] In current clinical practice, doctors primarily rely on preoperative oral CT scans to assess the overall thickness of the alveolar bone and combine this with clinical experience to determine the drilling direction, thus avoiding implant exposure postoperatively due to thin bone at the drilling location. Therefore, the surgeon performing the procedure must possess extensive experience and advanced skills, placing high demands on the surgeon. Especially when the alveolar bone is thin on the buccal and lingual sides, drilling requires even greater precision; otherwise, implant threads can easily become exposed, necessitating procedures such as bone grafting and periosteum covering, increasing patient costs. The fabrication of personalized surgical guides also implies longer waiting periods and higher patient costs.

[0004] To address the aforementioned problems, corresponding drilling guidance devices have been proposed, such as the handheld dental implant guide disclosed in utility model publication number CN222357657U. This handheld dental implant guide can improve drilling accuracy to a certain extent and assist in drilling; however, handheld operation also presents challenges due to factors such as vibration, leading to displacement and angular deviations. Utility Model Content

[0005] This invention addresses the issue of improving drilling accuracy for dental implants by proposing a dental implant preparation direction guide device with a different structure. Specifically, it is a simple dental implant preparation direction guide clamp, which is more suitable for patients with thin buccal and lingual bone plates.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows: A simple dental implant preparation direction guide clamp includes a clamp body for clamping onto the alveolar bone and two tail handles for controlling the opening of the clamp body. The clamp body includes an elastic connecting plate at the top and clamp plates disposed on both sides of the elastic connecting plate. The two tail handles are respectively connected to the clamp plates on the corresponding sides. The feature is that a U-shaped recess is provided in the middle of the upper end of the tailstock, the bottom of the U-shaped recess is lower than the elastic connecting plate, a through hole is provided in the middle of the elastic connecting plate, and a downwardly extending guide tube is fixedly provided at the through hole.

[0007] In one embodiment of this utility model, the clamp has an extension at the center of its bottom edge, which is used to clamp onto the alveolar bone.

[0008] In one embodiment of this utility model, anti-slip teeth are provided at the position where the clamp contacts the alveolar bone.

[0009] As one embodiment of this utility model, the bottom of the guide tube is provided with a positioning tip.

[0010] As one embodiment of this utility model, the tail handle includes two symmetrically arranged vertical rods, a rotating shaft extending laterally outward from the bottom of the vertical rods, a transverse extension rod extending laterally outward from the top of the vertical rods, a curved portion at the end of the transverse extension rod, and a connecting rod connecting the two curved portions. A connecting portion is provided on the outer side of the two corners of the bottom edge of the clamping plate, and the rotating shaft is placed inside the connecting portion. The curved portion is higher than the elastic connecting plate, and the lateral extension rod is lower than the elastic connecting plate. The curved portions on both sides and the lateral extension rod in the middle form the U-shaped recess.

[0011] In one embodiment of this utility model, the elastic connecting plate and the clamping plate are integrally formed from stainless steel sheet.

[0012] In one embodiment of this utility model, the clamping plate has a width of 1.0-1.3cm and a height of 1.5-1.8cm; the guide tube has an inner diameter of 2.5-2.7mm or 3.5-3.7mm and a height of 0.5-0.7cm; and the elastic connecting plate has a width of 1.0-1.3cm.

[0013] The beneficial effects of adopting the above technical solution are as follows: This invention provides a dental implant preparation direction guide clamp. The clamp body secures a guide tube to the alveolar bone. After adjustment, the guide tube serves as a drilling guide. The dentist holds the dental implant handpiece and drills along the guide tube. Using this invention to guide the preparation direction during dental implantation significantly improves drilling accuracy. Furthermore, this invention has a simple, compact, and flexible overall structure, is easy to use, and is easy to sterilize. It can be reused or used as a disposable product.

Detailed Implementation

[0020] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be clearly and completely described below in conjunction with specific embodiments.

[0021] like Figure 1 and Figure 2 The illustrated simple dental implant preparation guide clamp includes a clamp body for clamping onto the alveolar bone 101 and two tail handles 3 for controlling the opening of the clamp body. The clamp body includes an elastic connecting plate 1 at the top and clamping plates 2 on both sides of the elastic connecting plate 1. The two tail handles 3 are respectively connected to the corresponding clamping plates 2. Connecting parts 2-1 are provided on the outer sides of the two corners of the bottom edge of the clamping plates 2. In the closed state of the clamp body, the cross-section of the two clamping plates 2 and the elastic connecting plate 1 is triangular. In the open state of the clamp body, the cross-section of the two clamping plates 2 and the elastic connecting plate 1 is U-shaped. When opened, the elastic connecting plate 1 bends and deforms to provide clamping force.

[0022] The upper middle part of the tailstock 3 is provided with a U-shaped recess, the bottom of which is lower than the elastic connecting plate 1. The elastic connecting plate 1 is provided with a through hole 4 in the middle, and a downwardly extending guide tube 5 is fixedly installed at the through hole 4. The main function of the U-shaped recess is to expose the middle part of the clamping body, so as to prevent the tailstock 3 from obstructing the mobile phone 104 and the drill bit 103.

[0023] like Figure 1 and Figure 4 As shown, the clamp 2 has a connecting part 2-1 on the outer side of the two corners of its bottom edge, and an extension part 2-2 in the middle of its bottom edge. The extension part 2-2 is used to clamp onto the alveolar bone. The connecting part 2-1 is higher than the extension part 2-2, so that the extension part 2-2 can penetrate further into the gingiva 102, thus preventing the gingiva 102 from obstructing the connection between the clamp and the alveolar bone 101.

[0024] like Figure 2 and Figure 3 As shown, anti-slip teeth 2-3 are provided on the clamp 2 at the position where it contacts the alveolar bone 101. Specifically, in this embodiment, the anti-slip teeth 2-3 are provided on the extension 2-2. Since the contact area between the extension 2-2 and the alveolar bone is limited, and the alveolar bone has an uneven and irregular shape, the anti-slip teeth 2-3 can make the clamp body and the alveolar bone more stably and reliably bonded.

[0025] Preferably, the bottom of the guide tube 5 is provided with a positioning tip 5-1, which abuts against the top surface of the alveolar bone 101. Together with the anti-slip teeth 2-3 on both sides, it forms multi-point contact with the alveolar bone 101, further improving the stability of the clamp's connection with the alveolar bone. The height of the guide tube 5 can be configured according to actual needs, forming guide plate clamps of different sizes to suit different situations; for example, common dimensions for different positions can be obtained through data statistics, and guide plate clamps of corresponding sizes can be configured accordingly. In specific implementation, the guiding function is not affected even if the positioning tip 5-1 of the guide tube 5 does not contact the alveolar bone 101.

[0026] like Figure 4 As shown, in this embodiment, the tail handle 3 includes two symmetrically arranged vertical rods 3-1, a rotating shaft 3-2 extending laterally outward from the bottom of the vertical rods 3-1, a transverse extension rod 3-3 extending laterally outward from the top of the vertical rods 3-1, a curved portion 3-4 at the end of the transverse extension rod 3-3, and a connecting rod 3-5 connecting the two curved portions 3-4. A connecting portion 2-1 is provided on the outer side of the two corners of the bottom edge of the clamping plate, and the rotating shaft 3-2 is placed inside the connecting portion 2-1. The curved portion 3-4 is higher than the elastic connecting plate 1, and the transverse extension rod 3-3 is lower than the elastic connecting plate 1. The curved portions 3-4 on both sides and the transverse extension rod 3-3 in the middle form the U-shaped recess. The height of the curved portion 3-4 above the elastic connecting plate 1 should be such that it does not affect the surgical operation and facilitates opening the clamp. If necessary, other tools (such as surgical forceps) can be used to apply force to the two tail handles 3 to open the clamp.

[0027] The connecting part 2-1 is formed by the corner of the clamping plate 2 being rolled upward to form a tubular structure, and the two corners of the clamping plate 2 being rolled upward to form the middle extension part 2-2.

[0028] In this embodiment, the elastic connecting plate 1 and the clamping plate 2 are integrally formed from a thin stainless steel plate with a thickness of 0.2-0.3 mm. Based on the typical diameters of the alveolar bone 101 and the drill bit 103, the clamping plate 2 is configured with a width W of 1.0-1.3 cm and a height H of 1.5-1.8 cm. The guide tube 5 has an inner diameter of 2.5-2.7 mm or 3.5-3.7 mm and a height of 0.5-0.7 cm. The elastic connecting plate 1 has a width L of 1.0-1.3 cm. The drill bit diameter commonly used for the first drill is 2.2 mm; therefore, the inner diameter of the guide tube 5 should be slightly larger than the diameter of the first drill bit. The overall dimensions of the clamping body should be sufficient to stably clamp and fix the guide tube 5. The height of the guide tube 5 is set so that when the clamping plate 2 holds the alveolar bone 101, the guide tube 5 can just touch the top of the alveolar bone 101.

[0029] The tailstock 3 is formed by bending a steel wire.

[0030] like Figure 5 As shown, during installation, the gingiva 102 at the corresponding position can be flipped open first so that the splint 2 can directly contact the alveolar bone 101. When performing hole preparation operations (positioning, drilling, enlarging, etc.), first position the implant, and mark the preoperative CBCT design data of the implant placement direction (the relationship between the extension of the implant placement direction centerline and the buccal-lingual and mesiodistal directions of the opposing tooth). Then, place the direction measuring rod into the guide tube 5, and position the exposed part to the corresponding position of the opposing tooth. Adjust the position of the guide clamp so that the tilt direction is consistent with the direction measuring rod. At this time, the tilt direction of the guide clamp is the designed implant tilt direction. Fix the guide clamp (the tooth imprint positions of anti-slip teeth 2-3 can be made with corresponding dot-shaped grooves using a positioning drill to better fix the guide clamp) on the alveolar bone 101. After securing the guide plate clamp, the doctor holds the handpiece 104 and guides the drill bit 103 along the guide tube 5 (2.5-2.7mm in diameter) to perform the first drilling. During drilling, when the drill bit 103 contacts the guide tube 5, adjustments are made quickly to ensure accurate drilling position and direction. After the first drilling is completed, the guide plate clamp is removed for subsequent reaming operations. At this point, a guide plate clamp with a diameter of 3.5-3.7mm can be used for a second directional calibration during reaming to ensure no directional deviation during the reaming process (anti-slip teeth 2-3 can be positioned at the original groove).

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
