Dental implant structure

The present invention relates to the technical field of artificial implants, and in particular to a dental implant retainer structure that strengthens the fixation of the alveolar bone.

With the advancement of dental medical technology, the teeth are currently removed surgically for the more severely damaged teeth, and the artificial roots are implanted in the cogging of the removed teeth, and then placed on the upper end of the artificial root. Artificial crown to replace the tooth removed due to damage.

Referring to FIG. 1 and FIG. 2, the prior art artificial root 300 is disposed in the perforations 203 of the mutually connected gingiva 100 and the alveolar bone 200. The artificial root 300 has a head 301 and a thin The threaded portion 302 and a thick thread 303 are integrally formed at one end of the thin threaded portion 302, and the thick threaded portion 303 is connected to one end of the thin threaded portion 302 away from the head 301, and the thin threaded portion 302 is fastened At the perforation 203 and relative to the softer cartilage area 202 of the alveolar bone 200, the thick threaded portion 303 is threaded through the perforation 203 and is relatively hard with the hard bone region 201 of the alveolar bone 200. Corresponding to the gum 100 above the alveolar bone 200; in actual use, the prior art artificial root can be fixed to the cogging by osseointegration of the thin thread portion 302 and the thick thread portion 303 with the bone cells. Bone 200.

However, the force between the thin threaded portion 302 and the thick threaded portion 303 and the alveolar bone 200 is fixed only by a long time, and it is easy to be loosened for a long time, which is inconvenient for the patient, and is for the medical practitioner. The words are very troublesome.

In view of this, the creator has improved the shortcomings of the prior art, and after years of experience in this industry, he created the creation.

This creation department provides a dental implant holder structure, which is placed in the perforated bottom space of the alveolar bone by a capsule fixed to the artificial root, and uses a material such as silicone which does not harm the human body. The capsular bag is enlarged to be fixed in the bottom space of the perforation, and the firmness of the artificial root in the alveolar bone is improved, so as to avoid the situation that it is easy to loose under a long time.

Therefore, the purpose of the present invention is to solve the above problems and provide a dental implant fixture structure which is fixedly inserted in a perforation of a gingival and a alveolar bone which are laminated to each other, the dental implant holder structure including an artificial The root portion includes a head portion, a body portion and a center through hole, the body portion having a thin thread portion and a thick thread portion, the fine thread portion being disposed adjacent to the head portion, the thick thread portion and the thin portion a threaded portion is connected away from one end of the head, the central through hole is bored in an axial direction of the body; and an elastic bag is fixed to the bottom of the body and communicates with the central through hole, the elastic bladder The bag is fastened in a spherical space at the bottom of the perforation; wherein a silicone material is poured into the elastic bag through the central through hole, so that the elastic bag is gradually expanded to support the spherical space, and further The artificial root is fixed.

In some embodiments, the thick threaded portion is secured to the perforation and is located in a hard bone region of the alveolar bone, the fine threaded portion being secured to the perforation and located at a softer portion of the alveolar bone. In a cartilage area, the head is placed over the gum above the alveolar bone.

In other embodiments, the elastic bladder is made of silicone.

In one embodiment, the implant fixture structure further includes a soft sleeve that is sleeved on the head of the artificial root.

The above objects and advantages of the present invention will be readily understood from the following detailed description of the embodiments and the accompanying drawings.

Of course, the present invention is allowed to differ in some of the parts, or the arrangement of the parts, but the selected embodiments are described in detail in the present specification, and the construction thereof is shown in the drawings.

Figure 5 is a cross-sectional view showing the implanted alveolar bone of the present implant anchor structure.

Referring to FIGS. 3 to 5, the dental implant structure 1 of the present invention may include an artificial root 2 and a bladder 3.

The artificial root 2 can include a head portion 21, a body portion 22, and a center through hole 23. The body portion 22 has a thin threaded portion 221 and a thick threaded portion 222. The thin threaded portion 21 is disposed adjacent to the head portion 21, and is thick. The threaded portion 222 is connected to one end of the thin threaded portion 221 away from the head portion 21, and the central through hole 23 is bored in the axial direction of the body portion 22.

Furthermore, the gingival 100 and the one-toothed bone 200 are lapped through each other with a through hole 203. The bottom of the fixing hole is substantially a spherical space 204, and the thick threaded portion 222 can be fixed to the through hole 203 and located at the tooth groove. The hard bone region 201 where the bone 200 is harder, the fine thread portion 221 can be fixed to the perforation 203 and located in the cartilage region 202 where the alveolar bone 200 is soft, and the head portion 21 can be worn over the alveolar bone 200. 100 places.

The elastic bladder 3 can be made of silicone rubber, but not limited thereto; the elastic bladder 3 can be fixed to the bottom of the body 22 of the artificial root 2 and communicate with the central through hole 23, and the elastic bladder 3 is in the perforation. The bottom of the 203 is in the spherical space 204.

When the fixation is performed, the artificial root 2 and the capsule 3 are placed in the perforation 203, and a silicone material 5 is poured into the elastic bladder 3 through the central through hole 23, so that the elastic bladder 35 is gradually expanded to support the spherical shape. The space 204, in turn, secures the artificial root 2 .

In addition, the artificial dental implant fixture 1 of the present invention may further comprise a soft sleeve 4, and the soft sleeve 4 is sleeved on the head 21 of the artificial root 2; in detail, the soft sleeve 4 is inserted into the perforation of the artificial root 2 After 203, the head 21 of the artificial root 2 is placed, and after the gum 100 and the alveolar bone 200 are healed, the soft sleeve 4 is removed to carry out the installation of the artificial crown (not shown).

With the above structure, the silicone which does not affect the human tissue and the elastic capsule are utilized. The bag is fixed to the artificial root to improve the firmness of the artificial root, and the bag is made of elastic material, does not compress nerves or human tissues, is safe, and has a simple structure and simple operation.

The above description of the embodiments is intended to be illustrative of the present invention and is not intended to limit the present invention, so any change in the value or substitution of equivalent elements should still fall within the scope of the present invention.
