Technical Field

The invention relates to the technical field of dental implants, in particular to a bone shaper and an implant assembly.

Background

The dental implant mainly comprises an implant body, an abutment and a dental crown. The process of implanting the tooth is as follows: s1, preparing a hole on the alveolar bone and implanting the implant; s2, waiting for the implant to be combined with the bone; s3, a secondary surgeon cuts the gingiva, installs the healing abutment, enables the healing abutment to penetrate out of the gingiva and waits for the formation of soft tissue; s4, after the soft tissue is formed, the healing abutment is detached, and the permanent abutment is installed; and S5, wearing a crown.

The following three conditions are often encountered in dental implants:

referring to fig. 1, fig. 1 is a schematic view illustrating a structure of an implant, an artificial bone and a bone tissue when a bone tissue is defective according to the prior art; alveolar bone from which teeth are lost may be subject to bone resorption due to trauma of tooth extraction, etc. In the case of dental implantation, if the bone height or the bone thickness is insufficient due to a defect of bone tissue, it is necessary to implant the artificial bone 300, which has various materials and is generally filled in the missing position of the alveolar bone in the form of bone powder (granules). As shown in fig. 1. Because the growth speed of the bone tissue is slow, the periosteum 400 only plays a barrier role, a patient can eat normally after the soft tissue is healed, the chewing force downwards, front and back and left and right after the material object is filled, and the bone forming effect is poor and the bone forming shape is not ideal under the pressure conduction of the soft tissue 100 where the artificial bone 300 is located; poor effect of vertical bone increment, etc. In this case, the titanium mesh is usually wrapped outside the artificial bone 300 in the prior art, as shown in fig. 1, the titanium mesh is relatively hard, but the artificial bone 300 after being implanted is protected by the titanium mesh and is generally used when the bone defect is large, a larger wound is artificially made to facilitate the implantation of the titanium mesh, and the titanium mesh needs to be taken out by a secondary operation, so that the time and the capital cost are extremely high. The pain of the patient is great.

Referring to fig. 2, fig. 2 is a schematic view illustrating a structure of a prior art implant implanted under bone tissue; when the tooth is implanted under normal conditions, in order to increase the survival rate and survival effect, the implant 2 is implanted into the bone for 1-2mm, then the neck of the implant is sealed by a cover screw, the soft tissue opening is tightly sutured, and the implant 2 is waited to be integrated with the bone tissue 200; in this case, as shown in fig. 2, after the implant 2 is integrated with the bone tissue 200, the bone at the neck of the implant 2 needs to be destroyed again to facilitate the repair, and at this time, the bone needs to be ground by a doctor to form a bone socket. Screwing the healing abutment to wait for the gingiva to be formed, and then repairing the worn crown. This procedure is a primary procedure, requiring a secondary procedure. When the neck bone fossa of the implant is polished in a secondary operation, the implant is easy to damage, and further the failure of the surviving implant is caused, or the use time is reduced after the damage; the bone pit polishing time and cost are high, and the pain of the patient is great.

The doctor can avoid the secondary operation with healing base station screw in, avoids patient's secondary misery. This method of using the healing abutment to leak out of the soft tissue may greatly reduce the survival rate in patients with bad oral environment and alcohol smoking, or may cause the failure of implant implantation due to chewing and tongue licking of the healing abutment.

Referring to fig. 3, fig. 3 is a schematic view showing a fitting structure of an implant, bone tissue and an artificial bone in a maxillary sinus cavity in the prior art; when the maxillary sinus lifting is needed in the implantation operation, namely, the implant 2 is implanted after the artificial bone 300 is filled in the maxillary sinus cavity 500, the maxillary sinus floor membrane is broken or leaks when being lifted, or bad tissues are brought when the artificial bone is implanted to generate inflammation. The implant may fall into the upper frontal sinus cavity with more serious consequences. If a healing abutment with a larger diameter is screwed in during the operation, the risk of falling into the sinus cavity is solved, but the survival rate is reduced.

In summary, in the prior art, the artificial bone is difficult to form a good bone shape only by fixing the artificial bone by means of periosteum, titanium mesh and the like, and the operation cost and the time cost are high, so that the pain of a patient is great. After the healing abutment is used, the implant can be implanted under the bone, a bone pit and a gum pit can be formed smoothly, but the survival rate is reduced, and only a few patients can adopt the healing abutment.

In order to facilitate the connection of the former body 1 with the torsion device, referring to fig. 4 and 5, the former body 1 of the present embodiment is provided with a screwing cavity 15, the screwing cavity 15 extends from the surface of the supporting portion 11 to the inside of the former body 1, the screwing cavity 15 is used for connecting with the torsion device, and when the two are connected, the former body 1 can be screwed into the implant 2, and the former body 1 can be screwed out from the implant 2. The torsion device can be a special screwing abutment device in the field of dental implants, and details are not described herein. The screwing cavity 15 is convenient for the former body 1 to be connected with a torsion device, and prevents the former body 1 from being implanted into the implant 2 or pulling out the implant 2.

Referring to fig. 5 to 8, an implant assembly including the implant 2 and the above-described bone shaper is also provided according to an embodiment of the present invention.

The implant 2 is matched with the bone shaper, and the bone shaper can support the artificial bone 300, so that the artificial bone 300 can be conveniently shaped, and the survival rate of the implant 2 is improved; the neck bone tissue of the implant 2 is not needed to be polished in a secondary operation, so that the pain of a patient is relieved; even in the case of a small amount of bone tissue 200, it is possible to fix the implant 2 well and prevent the implant 2 from falling into the maxillary sinus cavity 500.

The following is a comparative description of the three cases mentioned in the background.

Example one

Comparing fig. 1 and 6, when bone tissue 200 is defective:

in the prior art shown in fig. 1, the periosteum 400 or the titanium mesh is used to wrap the artificial bone 300 in the prior art, the periosteum 400 is soft, the protection effect is poor, and the artificial bone 300 is not easy to form; the implantation of titanium mesh requires the creation of a larger wound, causing pain to the patient.

In the embodiment shown in fig. 6, after the shaper body 1 and the implant 2 are connected in place, the support portion 11 is located outside the bone tissue 200 and abuts against the outer edges of the artificial bone 300 and the bone tissue 200, and is located between the soft tissue 100 and the bone tissue 200 to protect the implanted artificial bone 300 and the periosteum 400 from being extruded and deformed, so that a good bone shape can be obtained; larger wound does not need to be made manually, the cost is lower, and the pain of the patient can be relieved by taking out the wound in the secondary operation.

Example two

Comparing fig. 2 and 7, when the implant 2 is normally implanted, in order to ensure survival rate and prolong the life span, the doctor implants the implant 2 1-2mm below the bone tissue 200:

in the prior art shown in fig. 2, it is necessary to destroy the bone of the neck of the implant 2 again for repair, at which time the bone is required to be ground by the doctor to form a bone socket; the secondary operation brings more pain to the patient.

In the embodiment shown in fig. 7, the implant 2 is implanted into a bone, the supporting portion 11 is abutted against the outer edge of the bone tissue 200, after the bone shaper is taken out, the soft tissue 100 does not need to be cut secondarily and the bone tissue 200 around the neck of the implant 2 does not need to be ground, the bone shaper is taken out conveniently, the bone forming pit 600 is naturally formed around the upper part of the neck of the implant 2, the pain of a patient is reduced, and time and labor are saved; and the bone shaper is below the soft tissue 100 which is closely sutured, so that the survival rate of the implant 2 is not influenced.

EXAMPLE III

Comparing fig. 3 and 8, when it is desired to perform the maxillary sinus lift procedure:

in the prior art shown in fig. 3, when the maxillary sinus lift is required for the implant operation, that is, the implant 2 is implanted after the maxillary sinus cavity 500 is filled with the artificial bone 300, there is a case that the inferior membrane of the maxillary sinus is lifted, or a leak hole is formed, or an inflammation is generated by introducing a bad tissue when the artificial bone is implanted. The implant may fall into the upper frontal sinus cavity with more serious consequences.

In the present embodiment illustrated in fig. 8, the support part 11 is abutted against the outside of the bone tissue 200 and connected with the implant 2, and even if a small amount of bone fixes the implant 2, it is difficult for the implant 2 to fall into the maxillary sinus cavity 500 and the implant is effectively protected from surviving under the sutured soft tissue 100.
