Description

[0001] TITLE: A EZEE APICALLY EXPANDING IMPLANT

[0002] FIELD OF THE INVENTION:

[0003] The present invention generally relates to the field of dentistry. Specifically, the present invention relates to an apically expandable dental implant. More particularly, the present invention relates to an apically expandable dental implant for greater stability and bone anchorage.

[0004] BACKGROUND OF THE INVENTION:

[0005] Artificial teeth are man-made teeth having almost the same appearance and functions as human natural teeth and are used to replace natural teeth lost due to various causes.

[0006] Prosthetic appliances, dentures, and artificial teeth are used as substitutes for natural teeth. When using prosthetic appliances, since other neighboring natural teeth need to be partially ground, the natural teeth are damaged a lot. Moreover, the life span of prosthetic appliances is about 10 years - not long term. When using dentures, natural teeth are damaged during preparation for fabricating dentures. In addition, dentures may come out of a mouth and make users uncomfortably feel a foreign body sensation in their mouths. For these problems, the use rates of prosthetic appliances and dentures haven been decreased. In the meantime, when artificial teeth are fixed to an alveolar bone, other neighboring natural teeth are not damaged. Artificial teeth after being fixed are sufficiently the same as natural teeth in appearance and functions to be difficult to be discriminated from natural teeth. In addition, their life span is semi-permanent depending on maintenance.

[0007] When an artificial tooth is fixed to an alveolar bone, a dental implant is used. In other words, the body of a dental implant is fixed in an alveolar bone, and then an artificial tooth is joined with the body of the dental implant so that the artificial tooth is used like a natural tooth. Conventional implants are in conical shape either two-piece implants or single piece implants. It is dependent on crestal bone for its anchorage. It injures the vital structures near them in certain circumstances. Conventional implants are contraindicated in bone loss conditions. Removal of implant could be difficult in implant failure cases.

[0008] There are reports available in the state of the art relating to dental implants.

[0009] US8636511B2 discloses a dental implant system, comprising: a screw including a head and a threaded end portion; a dental implant comprising: a proximal end; an internal bore extending distally from the proximal end, the internal bore including an upper tapered section, an anti-rotation section having a non-round shape and including at least one planar surface, a lower section having a dimension that is smaller than a dimension of the anti-rotation section, and a threaded section distal of the lower section, the antirotation section being located between the upper tapered section and the lower section; an external surface including an external-threaded section, a portion of the anti-rotation section being located distal to a proximal end of the external-threaded section of the implant; and a unitary abutment for attachment to the dental implant comprising: a tapered first section including a first dimension and being received in the upper tapered section of the internal bore of the implant; a second section having a predetermined shape adapted to rotationally lock with the anti-rotation section of the dental implant, the second section including a second dimension that is smaller than the first dimension of the tapered first section; a third section including a third dimension that is smaller than the second dimension and adapted to assist axial insertion of the abutment into the dental implant, the second section being located between the first section and the third section, the third section of the abutment having a cylindrical shape; a tapering section that is above the first section and outside of the implant, the tapering section tapering outwardly in a direction from the implant toward a proximal end of the abutment; a prosthesis-supporting section that is above the tapering section and configured to support a prosthesis, the prosthesis-supporting section having a length that is greater than a length of the tapering section; a through-bore extending along a longitudinal axis of the abutment; and an internal shoulder integrally formed within the abutment and partially defining the through-bore, the internal shoulder engaging the head of the screw when the screw passes through the through-bore and the threaded end portion threadably engaging the threaded section of the internal bore of the dental implant so as to axially retain the abutment on the implant with the tapered first section of the abutment received in the upper tapered section of the internal bore of the implant, the axial retention inhibiting axial movement of the abutment distally and proximally relative to the implant.

[0010] US4180910A discloses an implant for fixing an artificial replacement tooth to a jaw, comprising a post for firmly holding said replacement tooth and at least two hollow cylindrical bodies having parallel axes, said bodies each being rigidly connected to said post, open at a respective one axial end and having a cylindrical wall which is intended to be inserted into the bone of said jaw and which is provided with means defining passages therethrough.

[0011] US4626214A discloses improved fixed dental implant of the type fixed to the maxilla, comprising a first elongated body having external thread means for securing said first body to the maxilla with one end of said first body extending into the maxilla, said first body having an axial internal bore extending out of the other end thereof, a second elongated body bearing a dental prosthesis at one end and having a shaft portion at the other end dimensioned to be removably received within said bore with a pressure fit, but to be moveable under normal chewing action, a free face on said first body through which said bore extends, an opposing face on said second body positioned to be opposed to said free face when said shaft portion is received in said bore, and sealing means interposed between said free face and said opposing face, said sealing means being made of a sufficiently resilient material so as to serve as a force absorber between said first and second bodies, while also serving as a seal.

[0012] Though conventional dental implants exhibit advantages in the prior arts, they do exhibit disadvantages such as comparatively less bone anchorage and stability as it depends only on crestal bone support, damaging the vital anatomical structures in certain situations by its long conical shape, contraindicated in bone loss conditions, removal of implant could be difficult in implant failure cases.

[0013] Thus, there exists a need in the state of art for an alternative dental implant with enhanced bone anchorage, stability and durability.

[0014] Hence an attempt has been made to fabricate an apically expandable dental implant for greater stability and bone anchorage which is devoid of above said drawbacks.
