Description

  The present invention relates to a package for housing a dental implant, and in particular, to a package for housing a dental implant in which a fixture and an attachment are combined together.

  It has been clinically already practiced that an implant is implanted in the alveolar bone at a site where a tooth is missing and a denture is attached to the distal side of the implant to substitute a natural tooth.

  In general, dental implants that are housed and packaged in a package in an aseptic environment are transported to a dental clinic or the like for use. Packages for receiving and transporting dental implants have been proposed and provided in various forms.

  A package for housing a dental implant is disclosed in Patent Document 1, for example.

JP 2004-243127 A

  In the implant package disclosed in Patent Document 1, an implant holder is disposed in a case having a shape of a plane hexahedron that is halved diagonally, and a slit with a notch for the implant holder to elastically hold the implant is provided. The implant that is provided and gripped by the notched slit is configured to be attached or detached through the opening. That is, the slit is made of an elastic material or covered with a lip made of an elastic material, and the slit with notches is elastically expanded to grip or release the cylindrical implant. It is comprised so that it can do.

  By the way, in general, the thread of the implant is subjected to surface processing such as roughening by sandblasting or coating processing such as calcium phosphate in order to strengthen the intraosseous maintenance force. If these surface processed threads are rubbed in direct contact with other members before being embedded in the alveolar bone, the surface processing applied to the implant will be altered, and the implant Does not have the ability to maintain bone.

  In the implant package of Patent Document 1, when the implant is attached to or detached from the slit, the surface-treated thread of the implant rubs against the side wall surface of the slit. As a result, there is a problem that the surface processing of the screw thread is altered and the implant cannot obtain a strong intraosseous maintenance force.

  Moreover, in the package for implants of Patent Document 1, when viewed from the opening side, a slit with a notch is tapered, so that a large-diameter implant is a notch portion on the opening side and a small-diameter implant is a non-opening portion It is comprised so that it can each accommodate in the notch part of the side. In order to accommodate many different diameter implants, many notches are required, which necessitates long slits extending in the depth direction from the opening, which necessitates a large implant package. There is a problem of becoming.

  Therefore, the technical problem to be solved by the present invention is that the surface treated portion of the fixture can be used for dental treatment without contact with other members before being embedded in the alveolar bone. It is to provide a package for containing an implant.

Means and actions / effects for solving the problem

  In order to solve the above technical problem, according to the present invention, the following packages are provided.

That is, the package for housing the dental implant according to the present invention is:
A fixture that has external threads and is embedded in the alveolar bone;
A neck portion located between the head portion and the fitting portion having a fitting portion for fitting to the fixture at one end and a head portion to be attached to the driver holder at the other end. A package for housing a dental implant integrally combined with a driver attachment having a narrowed portion whose diameter is reduced from the surroundings,
The package is
A holder for detachably holding the dental implant through the opening;
A case for holding the holder;
A cap that covers the case,

  The package for housing a dental implant according to the present invention relates to a package for housing a dental implant in which a fixture and a driver attachment are combined together in advance.

  According to the above configuration, the narrow portion reduced in diameter from the periphery provided in the driver attachment is elastically engaged with the U-shaped notched portion provided in the holder, The dental implant is clamped. Since the part that engages with the holder is a driver attachment, the surface of the fixture embedded in the alveolar bone is processed when the dental implant is attached to or removed from the holding part. The screw thread is not rubbed against the side wall surface of the clamping portion. Therefore, it is possible to handle the fixture without contacting the other members before the surface-treated thread of the fixture is embedded in the alveolar bone.

  Although there are various sizes of fixtures, the narrow portion of the driver attachment combined with the fixture can be shared, so that any size fixture can be supported.

  The engaging means in the clamping part is, for example, a locking claw protruding from the side wall surface of the clamping part.

  According to the above configuration, when the narrow portion of the driver attachment is pushed into the holding portion of the holder made of an elastically deformable material, the holding portion is slightly expanded to accept the narrow portion. Although the slightly expanded pinching portion returns to the original opening size, the locking claw functions as a pop-out preventing stopper, so that the dental implant is stably pinched without popping out.

  Moreover, the engaging means in the said clamping part is the latching recessed part dented in the side wall surface of the clamping part.

  According to the above configuration, when the narrow part of the driver attachment is pushed into the holding part of the holder made of an elastically deformable material, the holding part slightly expands and the narrow part is formed by the locking recess. accept. Although the slightly expanded pinching portion returns to the original opening size, the locking recess functions as a pop-out prevention stopper, so that the dental implant is stably pinched without popping out.

  The holder holder with the dental implant is locked in the package by a support portion provided in the center of the cap and extending toward the case contacting the upper surface of the head portion of the driver attachment.

  According to the said structure, since the holder holder with a dental implant is stably hold | maintained in a package, it can carry and store, without a dental implant separating from a holder.

  The fixture and the driver attachment can be combined together in various forms, but are connected by a connection screw inserted from the communication hole.

  The holder may have a substantially cylindrical shape, but is preferably a substantially regular polygon from the viewpoint of ease of handling when temporarily placed on a mounting table or the like, that is, from the viewpoint of preventing the holder from rolling. is there.

  By pulling out the dental implant together with the driver holder from the opening side, the engaged dental implant can be easily removed from the holding part of the holder. By pressing a pair of pressing marker portions arranged on both sides, the side surface of the holder is elastically deformed and the holding portion is slightly expanded, so that the dental implant held by the holding portion is further simplified. It becomes possible to leave.

  Alternatively, a U-shaped notch is provided on the same side of the upper and lower ends of the holder, the U-shaped notch on the upper end side is used as a clamping portion, and a pressing marker portion is disposed at a position near the notch on the lower end side. It can be set as the structure which has. In such a configuration, when the pressing marker portion is pressed, the side body in the vicinity of the notch on the lower end side is slightly crushed, but by the reaction of the crushing, the side surface of the holder is elastically deformed and the clamping portion By slightly expanding the dental implant, the dental implant held by the holding portion can be detached.
