Abstract
An implanter is provided, which enables rebuilding of an interdental papilla with a simple method. An implanter 1 is made up of a T-shaped steel member as a main body. The lateral side portions centering a web portion 2 in a flange portion 3 are inclined so as to be closer to the web portion 2 with respect to a plane perpendicular to the web portion 2, to provide an angular shape, with its peak residing in a portion joining with the web portion. A plurality of holes 4 large enough for gingival fibers to thrust in are opened in the flange portion 3. One or more embedding portions 5 are projected from a tip end portion (lower end portion) of the web portion 2. Each of the embedding portions 5 has a tip end portion with at least an acute shape, or a shape that enables embedding by being driven into alveolar bone 10.
Claims2
An implanter for embedding in an interdental space between teeth, the implanter comprising:
- an embedding portion configured to be embedded in alveolar bone beneath an interdental papilla portion in the interdental space between two teeth, the interdental space having a width between the two teeth;
- and
- an implanter body integral with and extending from the embedding portion and configured to project above the alveolar bone, the implanter body having a surface in which holes are formed, the holes configured for receiving gingival fibers therein to embed the implanter body in gingival, wherein the implanter body comprises:
- an upright portion which has a planar configuration with an upper end portion and a lower end portion, the embedding portion extending from the lower end portion, wherein the upright portion is configured to extend in a direction orthogonal to the width of the interdental space when embedded;
- and
- a roof portion having an apex at the upper end portion of the upright portion with side portions extending from the apex on both sides of the upright portion, the side portions configured to extend toward the teeth of the interdental space when embedded so as to have an angular shape as viewed from the direction orthogonal to the width of the interdental space, wherein the roof portion and the upright portion define a cavity on each side of the upright portion.
