Description

Technical Field

[0001] This utility model relates to the field of planting bridge technology, specifically a planting bridge that facilitates the horizontal adjustment of a composite base. Background Technology

[0002] Implant bridges generally refer to metal or frame structures used to support dentures on dental implants; they are components that connect the implants and the superstructure.

[0003] For example, Chinese patent CN223208522U discloses a dental implant bridge, including a support column. The bottom end of the support column is fixedly connected to a main bolt, and the top end of the support column is fixedly connected to an adjustment mechanism. The top end of the adjustment mechanism is movably connected to a connecting column, and the top end of the connecting column is movably connected to an implant. A limiting plate is fixedly connected inside the connecting column, and a connecting bolt is movably connected to the opposite side of the limiting plate. A set of left-right symmetrical adjustment grooves are opened on the outer wall of the connecting column. By rotating the adjustment rod on the adjustment mechanism, the top end of the telescopic rod can be moved up and down, thereby moving the top end of the telescopic plate up and down, thus adjusting the distance between the connecting column and the support column, thereby reducing the gap between the implant and the gingiva, thereby improving the comfort of the user. The stability of the telescopic plate during movement is improved by the spring, thereby preventing shaking after prolonged use.

[0004] Existing implant abutments typically employ a fixed height design or rely on multiple abutment sizes to adapt to different alveolar bone heights, resulting in cumbersome clinical procedures and high costs. Conventional implant posts are mostly one-piece structures with fixed angles or only minor adjustments, making it difficult to meet the restoration needs of complex occlusal relationships. Utility Model Content

[0005] The purpose of this invention is to provide an implant bridge that facilitates horizontal adjustment of the composite abutment, thereby solving the problem in the prior art where existing implant abutments typically employ a fixed height design or rely on multiple abutment sizes to adapt to different alveolar bone heights, resulting in cumbersome clinical operations and high costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a planting bridge that facilitates horizontal adjustment of the composite abutment, comprising an implant body, wherein an abutment is installed inside the implant body;

[0007] The abutment has threads on its outer side, and an adjusting nut is installed on the abutment through the threads on its outer side. The adjusting nut fits against the top end face of the implant to form a positioning structure. An adjustable post is installed on the top of the abutment.

[0008] Preferably, a fixing disk is fixedly connected to the top of the base, and a flange is formed on the outer side of the fixing disk on the top of the base, and friction texture is provided on the outer side of the fixing disk.

[0009] Preferably, a ball seat is provided at the middle of the upper part of the base, and the top of the ball seat passes through the fixing disk and forms an open structure in the middle of the fixing disk.

[0010] Preferably, threaded holes are provided inside both sides of the fixed disk, the threaded holes penetrate the interior of the fixed disk, and the two ends of the threaded holes are respectively connected to the interior of the ball seat and the outside of the fixed disk.

[0011] Preferably, a positioning bolt is threaded inside the threaded hole, the positioning bolt passes through the threaded hole and extends into the ball seat, and the end of the positioning bolt and the threaded hole faces the center of the ball seat.

[0012] Preferably, the implant has an internal mounting cavity, the abutment is threaded into the mounting cavity, and a baffle is fixedly connected to the top edge of the implant, the baffle being located outside the fixing plate.

[0013] Preferably, a connecting ball is fixedly connected to the bottom of the tooth post, the connecting ball is rotatably connected to the inside of the ball seat to form a ball joint structure, and the outer side of the connecting ball is provided with evenly distributed positioning holes, and the end of the positioning bolt is engaged with the inside of the positioning hole to form a positioning structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This implant bridge, which facilitates horizontal adjustment of the composite abutment, uses an adjusting nut on the outer side of the abutment to engage with the threaded part of the abutment, allowing the adjusting nut to fit snugly against the top end face of the implant to form a positioning structure. As the adjusting nut moves along the abutment thread, the depth to which the abutment is screwed into the implant mounting cavity can be precisely controlled, achieving stepless adjustment of the abutment height.

[0016] The connecting ball at the bottom of the post and the ball seat at the top of the abutment form a ball-joint rotation structure, allowing the post to rotate freely in three-dimensional space. Once the post is adjusted to the target angle, positioning bolts are screwed into the threaded holes on both sides of the fixing plate, causing the ends of the positioning bolts to engage with the positioning holes of the connecting ball, thus achieving rigid locking of the angle. The post direction can be dynamically adjusted according to the morphology of adjacent teeth and occlusal relationships, improving the functional adaptability of the restoration.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figures 1 to 6 The present invention provides the following technical solution:

[0026] like Figure 1 and Figure 2 As shown, an implant bridge that facilitates horizontal adjustment of the composite abutment includes an implant 1, with an abutment 2 installed inside the implant 1; the abutment 2 has threads on its outer side, and an adjusting nut 3 is installed on the abutment 2 through the threads on its outer side. The adjusting nut 3 fits against the top end face of the implant 1 to form a positioning structure, and an adjustable post 4 is installed on the top of the abutment 2.

[0027] like Figure 3 and Figure 4 As shown, a fixed plate 5 is fixedly connected to the top of the base 2. The outer side of the fixed plate 5 forms a flange on the outer side of the top of the base 2, and friction texture is provided on the outer side of the fixed plate 5.

[0028] like Figure 5 As shown, a ball seat 6 is provided at the middle of the upper end of the base 2. The top of the ball seat 6 passes through the fixing plate 5 and forms an open structure in the middle of the fixing plate 5. Threaded holes 7 are provided inside both sides of the fixing plate 5. The threaded holes 7 pass through the interior of the fixing plate 5, and the two ends of the threaded holes 7 are respectively connected to the interior of the ball seat 6 and the outside of the fixing plate 5. A positioning bolt 8 is threaded inside the threaded hole 7. The positioning bolt 8 passes through the threaded hole 7 and extends into the interior of the ball seat 6. The ends of the positioning bolt 8 and the threaded hole 7 face the center of the ball seat 6.

[0029] like Figure 3As shown, the implant 1 has an installation cavity 9 inside, and the base 2 is installed inside the installation cavity 9 by threads. A baffle 10 is fixedly connected to the top edge of the implant 1, and the baffle 10 is located outside the fixing plate 5.

[0030] like Figure 6 As shown, a connecting ball 11 is fixedly connected to the bottom of the tooth post 4. The connecting ball 11 is rotatably connected to the inside of the ball seat 6 to form a ball joint structure. The outer side of the connecting ball 11 is provided with evenly distributed positioning holes 12. The end of the positioning bolt 8 is engaged with the inside of the positioning hole 12 to form a positioning structure.

[0031] When assembling and adjusting the implant bridge that facilitates horizontal adjustment of the composite abutment, the implant 1 is first fixed in the alveolar bone as the basic support of the overall structure. The implant 1 has an installation cavity 9 inside. The abutment 2 is initially installed by engaging the threads on the outer side with the threads on the inner wall of the installation cavity 9.

[0032] The depth to which the base 2 is screwed into the mounting cavity 9 is adjusted by rotating the fixing plate 5 on the top of the base 2. The friction texture on the outside of the fixing plate 5 increases the friction between the hand and the fixing plate 5, making it easier for the operator to apply force to rotate. First, rotate the adjusting nut 3 to move it downward along the thread of the base 2 to a suitable position on the outside of the base 2. Then, rotate the adjusting nut 3 on the outside of the base 2 and rotate the fixing plate 5 to move the thread of the base 2 downward until the bottom of the adjusting nut 3 is tightly fitted with the top end face of the implant 1. At this time, the adjusting nut 3 restricts the up and down movement of the base 2 in the mounting cavity 9 by the force of the fitting with the implant 1, thereby achieving the positioning and fixation of the height of the base 2.

[0033] After the height of the base 2 is adjusted, the angle of the tooth post 4 is adjusted. The connecting ball 11 fixedly connected to the bottom of the tooth post 4 is fitted into the ball seat 6 in the middle of the upper end of the base 2 to form a ball joint rotation structure. Since the connecting ball 11 can rotate freely inside the ball seat 6, it drives the tooth post 4 to rotate synchronously, thereby realizing the multi-directional adjustment of the orientation angle of the tooth post 4.

[0034] After the angle of the dental post 4 is adjusted to the appropriate position, the positioning bolt 8 is rotated through the threaded holes 7 on both sides of the fixing plate 5. The positioning bolt 8 moves along the internal thread of the threaded hole 7 towards the center of the ball seat 6 until the end of the positioning bolt 8 is inserted into the positioning hole 12 on the outside of the connecting ball 11, forming a locking fit. At this time, the positioning bolt 8 restricts the rotation of the connecting ball 11 in the ball seat 6 through the locking force, thereby fixing the angle of the dental post 4 and completing the assembly and adjustment of the entire implant bridge. The baffle 10 at the top edge of the implant 1 is located on the outside of the fixing plate 5, which can protect the fixing plate 5 and surrounding components to a certain extent and reduce the impact of external impurities on the adjustment structure.
