Description

Universal rotary push structure for multi-size dental implants

technical field

The present invention relates to a universal rotary structure for multi-size dental implants, so that the rotary structure of the dental implant can be quickly rotated and positioned in response to different widths of the dental bone, and bone meal or filler can be pushed in at the same time, and the direction angle of the implant can be ensured. stability and reliability.

Background technique

Since the lateral torque generated by the non-axial force of the implant after dental implantation will greatly increase the stress (stress), therefore, the direction and angle of implant placement are very important, but the related cortical bone (cortical bone) Thickness is also an important factor, mainly because increased cortical bone thickness can significantly reduce stress values around implants. It is also for this reason that before the tooth is implanted, the condition of the gums is usually checked. If the thickness of the cortical bone is found to be insufficient, bone meal or fillings must be added to increase the thickness of the cortical bone.

When the thickness of the cortical bone in the implant area is insufficient and needs to be increased, the existing method is mainly to perform an osteotomy (osteotomy) to drill a hole of a set size in the cortical bone, and then fill the hole with bone powder (bone growth powder). ) or fillings to increase cortical bone thickness for subsequent implant procedures.

The traditional bone meal or filling tool for dental implants is mainly equipped with a push pin at the end of a handle to fill the bone meal or filling through the opening, but it is very difficult to use this traditional hand tool to fill the bone meal. Moreover, it is slow and time-consuming. In addition to increasing the discomfort of the patient, it is also a considerable burden on the time and physical strength of the doctor.

In today's more advanced dental implant surgery, during the process of positioning the implant body in the opening of the osteotomy operation, the bone meal or filling is simultaneously pushed out of the implant body through the relevant rotary structure of the implant body. The front end of the implant can be pushed in to reach the desired position. The evolution of this dental implant technology can quickly and simultaneously fill bone powder or fillings and position the implant. Faster and more convenient.

The dental implant should be able to be pushed in and positioned at the position of the patient's tooth bone, and at the same time be able to push the bone powder or filler to the desired position, of course, a relevant rotary structure must be provided. In the existing dental implant structure, the patient's tooth bone is mainly pushed through the helical cutting structure and the bone meal or filling is simultaneously pushed, especially in the helical structure, a helical groove must be provided for cutting positioning. However, since the patient places the implants on the dental bone with different widths, implants of different sizes and diameters must be used. All use the same rotary push structure, which seriously affects the convenience and appropriateness of the implant.

Contents of the invention

The purpose of the present invention is to provide a universal rotary push structure for multi-size dental implants, which can make the incision and positioning of the dental implants in different dentaries and the insertion of bone powder or fillings more rapid and convenient, and can make the implant implantation easier.

In order to achieve the above purpose, the present invention discloses a multi-size dental implant universal rotary push structure, including a dental implant, which is characterized in that: the dental implant is provided with a base portion with a set size and diameter, and the base portion The required thread portion is formed from bottom to top with a gradually decreasing diameter, and a plurality of equally spaced spiral grooves are provided to match the diameter of the base portion and run through the thread portion from bottom to top. The thread portion forms a plurality of spaced cutting ends, and forms an arc top at the top; the ratio of the diameter of the base of the dental implant to the number of the spiral grooves is between 1.2 and 2.0.

Wherein, the diameter of the base part is between 3 and 7 mm, and the number of the spiral grooves is between 2 and 4.

Wherein, the diameter of the base part is 3.75 mm, two opposite spiral grooves are provided, and the number ratio of the spiral grooves is 1.875.

Wherein, the diameter of the base portion is 4.5 mm, three equally spaced spiral grooves are provided, and the number ratio of the spiral grooves is 1.50.

Wherein, the diameter of the base part is 5.25 mm, four equally spaced spiral grooves are provided, and the number ratio of the spiral grooves is 1.3125.

Wherein, the thread portion and the spiral groove spiral in the same direction.

Wherein, the thread portion and the spiral groove spiral in opposite directions.

Through the above structure, the ratio of the diameter of the base of the dental implant to the number of the spiral grooves in the present invention is about 1.2 to 2.0, so that the dental implant can be rotated and positioned more conveniently according to different bone width positions. At the same time, push the bone powder or filler, and make the angle of implant placement more stable and reliable.

Detailed ways

As shown in Figures 1 to 4, this embodiment is a smaller size (such as 3.75mm) dental implant body 10, the material of this type of dental implant body can be zirconium dioxide, and the dental implant body 10 is provided with a specific size diameter The base part 11 of A, the diameter A matches the width of the cementum of different sizes, and the size is between 3mm and 7mm. In the following examples, the diameter A of Fig. 1 to Fig. 4 is 3.75mm, and Fig. 5 to Fig. 4 The diameter B in FIG. 6 is 4.5 mm, and the diameter C in FIGS. 7 to 8 is 5.25 mm, but this is only for convenience of illustration, not limitation.

Please refer to Fig. 1 to Fig. 4 again, the structure of the dental implant 10 includes the required thread portion 12 formed from bottom to top by the base part 11 in a manner of gradually reducing the diameter, and a plurality of threads matching the diameter A is provided with equally spaced spiral grooves 13 (in this embodiment, two opposite spiral grooves 13) that run through the threaded portion 12 from bottom to top, and the spiral grooves 13 cooperate with the threaded portion 12 to form a plurality of The cutting ends 14 are spaced apart, and an arc tip 15 is formed at the tip. The dental implant body 10 can thus be driven and rotated by a tool (not shown in the figure), cut and positioned at the position of the tooth bone, and synchronously push in bone meal or filler. At the same time, in this embodiment, the thread portion 12 and the spiral groove 13 spiral in the same direction, that is, when the thread portion 12 spirals clockwise from top to bottom in the drawing , the spiral groove 13 also extends downward in a clockwise direction.
