Technical Field

[0001] The utility model belongs to the field of dental implants, in particular to a flat dental implant. Background Art

[0002] The existing dental implants for bone-level implantation in the market have a cylindrical or cone-shaped appearance. Cavity preparation is required before implantation. When the width of the patient's alveolar bone is insufficient, bone augmentation surgery must be performed to increase the width of the alveolar ridge in the surgical area before preparing the cavity for implant implantation. The entire process has many steps and a complicated surgery. The operation cycle is long, the patient suffers from many illnesses, and the medical staff is burdened with a large amount of pain. Utility Model Content

[0003] In view of this, the utility model aims to provide a flat dental implant to avoid a large amount of alveolar bone loss, reduce the amount of bone substitutes used during surgery, reduce the difficulty of surgery, reduce surgery costs, and reduce the pain of patients.

[0004] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0005] A flat dental implant comprises a head, a neck and a root, wherein the head is connected end to end with the neck, and the neck is in a conical structure;

[0006] The front side of the root is V-shaped, and the root is connected with the neck to form an integral structure; the side of the root is flat;

[0007] The top section of the head is provided with a hexagonal hole.

[0008] Furthermore, the thickness of the neck is greater than the thickness of the root.

[0009] Furthermore, the necks arranged on the front and back sides of the root are provided with chip grooves, and the number of chip grooves on each side is 2.

[0010] Furthermore, a plurality of contact grooves are provided on the front and back sides of the root, and the contact grooves are V-shaped or circular in shape, and the depth of the contact grooves is 0.1-0.2 mm.

[0011] Furthermore, the ratio of the height of the head to the height of the root is 10:23.

[0012] Furthermore, the four corners of the root are all arc angles.

[0013] Furthermore, the ratio of the thickness of the root to the height of the root is 5:34.

[0014] Compared with the prior art, the flat dental implant described in the utility model has the following advantages:

[0015] The utility model discloses a flat dental implant. For implant surgery when the width of the alveolar ridge of a patient is insufficient, there is no need to perform bone augmentation surgery or step-by-step implantation socket preparation. Only the bone splitting technique is required and a cortical bone forming drill is used once to drill a hole for implantation of the new dental implant. This can reduce the amount of bone substitutes used during the operation, reduce the difficulty of the operation, reduce the cost of the operation, simplify the implantation steps, shorten the treatment time of the implantation operation, and reduce the pain of the patient.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0026] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0027] A flat dental implant, such as Figure 1-Figure 4 As shown, it comprises a head 1, a neck 2 and a root 3, wherein the head 1 is connected end to end with the neck 2, and the neck 2 is a conical structure;

[0028] The front side of the root 3 is V-shaped, providing a V-shaped or wedge-shaped guiding side, and the bone splitting instrument also has a similar wedge shape, which can increase the contact area between the dental implant and the patient's bone and improve the initial stability of the dental implant;

[0029] The root 3 is connected to the neck 2 to form an integral structure; the side of the root 3 is flat. When implanting a dental implant, the requirement for the width of the patient's alveolar ridge will be significantly reduced, and a thickness of 2 to 4 mm can meet the needs of implantation;

[0030] The top section of the head 1 is provided with a hexagonal hole 6 , and below the hexagonal hole 6 is a threaded hole.

[0031] Preferably, the thickness of the neck portion 2 is greater than the thickness of the root portion 3 .

[0032] Preferably, the neck 2 arranged on the front and back sides of the root 3 is provided with chip grooves 4, and the number of chip grooves 4 on each side is 2.

[0033] Preferably, a plurality of contact grooves 5 are provided on the front and back sides of the root 3. The contact grooves 5 are V-shaped or circular in shape. The depth of the contact grooves 5 is 0.1-0.2 mm. The contact grooves 5 can increase the contact surface between the implant and the native bone and improve the implantation stability of the product.

[0034] Preferably, the four corners of the root 3 are all arc angles. The arc angle design can reduce the stress concentration points on the implant surface and reduce the risk of damage to the implant or surrounding bone tissue due to stress concentration.

[0035] Preferably, the ratio of the height of the head 1 to the height of the root 3 is 10:23.

[0036] Preferably, the ratio of the thickness of the root 3 to the height of the root 3 is 5:34.

[0037] The overall size parameters of the implant are designed. This design can optimize the mechanical properties of the implant, so that after the implant is implanted in the alveolar bone, it can better disperse the chewing force and reduce the stress concentration on the surrounding bone tissue, thereby improving the stability and long-term success rate of the implant.

[0038] The appropriate height ratio helps to ensure the biocompatibility and integration of the implant with the surrounding bone tissue, which is beneficial to the initial healing and long-term stability of the implant.

[0039] When the width of the alveolar ridge is insufficient (2 to 4 mm), which cannot meet the implantation conditions of cylindrical or cone-shaped implants, this new structure dental implant can be used for implantation. By utilizing the good biological elasticity of the alveolar bone through bone splitting technology, it is only necessary to wedge the bone splitting instrument into the gap between the bilateral cortical bone plates to expand the horizontal width of the alveolar bone, and use a cortical bone forming drill to prepare a hole in the implantation area, the new implant can be implanted.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
