Definitions

  • This invention relates to an artificial tooth implant device comprising an implanting portion engageable into a jawbone for permanent retention therein.
  • the implant device will be held in place by the pressure of the bone tissue on the side surfaces of the implant blade portion the surface area of which is sufficiently large to produce effective retention when it is first driven into the bone by force applying means such as a mallet.
  • force applying means such as a mallet.
  • the bone structure grows through the opening provided in the blade portion to thereby retain the same within the jawbone.
  • This known implanting arrangement is objectionable in that the resistance of the gum and the slight pressure fit of the blade portion are insufficient for retaining the initially embedded blade portion in place against the effect of the mastication pressure tending to force the blade portion somewhat deeper into the bone structure so that the known arrangement cannot be relied upon for retaining an artificial tooth or tooth structure in the initially implanted position thereof.
  • Another ojbect of the invention is to provide an extremely dependable artificial tooth implant device which is simple in design and econimical to manufacture.
  • FIG. 1 is an enlarged view in perpsective of an artificial tooth implant device constructed according to one embodiment of the invention.
  • FIG. 2 is a perspective view of a jawbone portion provided with an artificial recess, and illustrating the manner in which the device shown in FIG. 1 is to be inserted in the recess.
  • FIGS. 3 and 4 are transverse and longitudinal sectional elevations respectively of the implant device after its insertion in the artificial recess shown in FIG. 2.
  • FIG. 5 is an enlarged view in perpective of an artificial tooth implant device constructed according to another embodiment of the invention.
  • FIGS. 6 and 7 are enlarged perspective views respectively of two further different embodiments of the invention.
  • the artificial tooth implant device I here shown is more particularly adapted for implantation within the molar and premolar region of a patients jawbone.
  • the implant device 1 is preferably in the form of a unitary metallic structure and comprises a thin flat anchoring plate 2 of square or rectangular shape having a smaller width than that of the jawbone portion into which plate 2 is to be introduced, and a post structure 3 projecting from a central portion of one face of the plate 2 in a direction substantially perpendicular thereto.
  • the plate 2 is provided with a plurality of openings 2a, and post 3 is adapted to support an artificial tooth such as shown at 9 in FIG. 3 and which may be secured onto the post 3 in any suitable manner such as by an application of cement.
  • the post 3 is preferably angular in cross section to snugly fit a corresponding cavity formed in the gingival end of tooth 9, with the longitudinal edges of such post being preferably smoothed off or rounded.
  • the post 3 may be hollow and be provided with an internal screwthread adaped to cooperate with an external screw-thread 5a formed on the shank of a screw member 5 which may be used as a means for fastening the artificial tooth to post 3.
  • a shank length portion 5b of screw member 5 extending above the threaded length 3 portion thereof may be bent so as to form a suitable angle with the threaded length portion 5a of the shank.
  • the anchoring plate 2 may have a length ranging between 18 and 28 mm, a width of 7.5 mm, and a thickness of 0.5 mm; the post 3 may have a length ranging between 12 and mm, and may be of square transverse section so as to present four side faces having each a width of about 2 As previously indicated, the implant device 1 is intended for transverse insertion into an artificial recess formed in a jawbone.
  • an incision is made in the mucous tissue on the crest of a jawbone portion 6 into which the device is to be inserted, which tissue is then scraped by means of a suitable tool so as to leave the underlying front or rear face portion of the bone uncovered, whereafter the artificial recess is formed in the bare rear face or front face portion of the bone.
  • This artificial recess consists of a substantially horizontal groove 7 and a vertical groove 8 extending from the groove 7 at substantially the midleng'th thereof to the crest of bone 6.
  • the groove 7 is intended for the reception of anchoring plate 2, and groove 8 for the reception of the post 3 of the implant device 1 shown in FIG. 1, with the groove 7 being located at such a distance from the bone crest that the length portion of the post 3 which will extend beyond said crest after insertion of the device is adequate for securing and adjusting an artificial tooth 9 onto said length portion of the post 3.
  • the grooves 7 and 8 such dimensions that the plate 2 and post structure 3 are frictionally engageable into their respective grooves whereby the device, upon complete insertion into the grooves, will be securely anchored in the bone structure without vertical, longi tudinal and transverse looseness relative to the bone structure, and this not only by virtue of its positive retention against displacements in two opposite vertical directions as well as in three horizontal directions, but also by virtue of its frictional retention against a displacement in the fourth horizontal direction, namely in a direction opposite to that of its frictional engagement into the grooves.
  • the groove 7 should have a depth such that the plate 2, when moved to its operative position in the groove 7, will lie entirely within the bone structure 6, whereas the depth of groove 8 should be such that its vertical bottom wall is spaced from the horizontal bottom wall of groove 7 by a distance equal to the distance existing between the edge of anchoring plate 2 intended to contact said bottom wall of groove 7 and the face of the post structure 3 intended to contact said bottom wall of groove 8.
  • the bone structure 6 grows through the openings 2a formed in the plate 2 to additionally lock the device in the anchored position thereof.
  • FIG. 5 is more particularly adapted for implantation within the incisor, canine, or posterior region of a jawbone.
  • This device differs from the device of FIGS. 1 to 4 only in that the anchoring plate 2 is of a substantially V-shaped form, the apex of which constitutes a transverse median portion of plate 2, and in that post structure 3 is positioned on the outer flattened face of such median portion substantially at the center thereof.
  • the construction of the anchoring plate 2 shown in FIG. 6 is the same as in FIG. 1, but the anchoring plate has on one of its flat faces two longitudinally spaced posts 3 and 3a extending from said face in substantially parallel relation.
  • the two posts 3 and 3a may be of same structure and may be of same or different length, with each post being adapted to have an artificial tooth or an artificial tooth structure such as a bridge or the like secured thereto.
  • anchoring plate 2 has been described as being of generally square or rectangular form, it should be understood that it may be otherwise designed without departing from the principles of the invention.
  • a flat anchoring plate of corresponding arcuate configuration such as shown at 10 in FIG. 7.
  • One of the two curved longitudinal edges of the plate 10 may be provided with a tapered cutout 11 permitting, is that is desired, to vary the radius of curvature of plate 10 by deforming the plate manually in such a manner as to approach the edges of cutout 11 towards each other.
  • the anchoring plate may be divided into two half portions having each a post structure normal thereto so that each half portion of the plate and its corresponding post structure may be used as an individual implant device such as shown in FIG. 2.
  • an anchoring plate having two or more longitudinally spaced post structues such as 3 and 3a thereon requires the formation of a corresponding number of longitudinally spaced post receiving grooves 8 in the rear or in the front face of the jawbone.
  • the device finds the grooves 7, 8, into which it is to be pushed, of a width so commensurate with the thickness of the anchoring plate and of the post structure, respectively, that it makes for ease of initial frictional inter-relation of the device with the grooves.
  • the width of the grooves should be found somewhat too large to assure the desired frictional interrelation, it is possible to compensate for this inconvenience by any suitable accurate expedient such as, for example, by deforming some edge length portions of the anchoring plate so that they protrude slightly from the plane of the plate.
  • An artificial tooth implant device engageable into a complemental artificial recess formed in the front or rear face of a jawbone for permanent retention of said device in said jawbone, said device comprising an implanting portion defined by a flat anchoring plate structure having at least one opening therein, and a mounting portion defined by an elongated post structure extending from a substantially central surface area of one face of said plate structure in a direction substantially perpendicular to said one face, and said post structure including means for mounting an artificial tooth or tooth structure on a free end length portion of said post structure.
  • said mounting means consists of a thread provided on said post structure along said free end length portion thereof, said thread being cooperable with a complemental thread of a fastening means for an artificial tooth or tooth structure to be secured onto said free end length portion of said post structure.
  • An artificial tooth implant device intended for. insertion into and permanent retention within a recess of corresponding configuration formed in a front face portion or in a rear face portion of a jawbone structure, said device comprising a flat anchoring plate having two opposite transverse edges and two opposite substantially parallel longitudinal edges, at least one opening formed in said plate, said opening having a dimension sufficient to permit the jawbone structure provided with said device to grow through said opening, a post structure extending from a central portion of said plate in a direction substantially perpendicular thereto, and means for securing an artificial tooth or tooth structure on said post structure.
  • An artificial tooth implant device intended for insertion into and permanent retention within a recess of corresponding configuration formed in a front face portion or in a rear face portion of a jawbone structure, said device comprising a flat anchoring plate having two opposite transverse edges and two opposite substantially parallel longitudinal edges, at least on opening formed in said plate, said opening having a dimension sufficient to permit the jawbone structure provided with said device to grow through said opening, a hollow post structure extending from a central portion of said plate in a direction substantially perpendicular thereto, said hollow post structure being provided with an internal thread adapted to cooperate with an external thread formed on a fastening means for an artificial tooth or tooth structure to be secured onto said post structure.
  • said fastening means consists of arod member having a length portion provided with said external thread and a length portion bent relative to said threaded length portion so as to form a predetermined .angle therewith.
  • said anchoring plate is bent longitudinally so as to present two plate portions diverging from a transverse median portion, said post structure projecting from the middle of the outer face of said median portion in a direction substantially perpendicular thereto.
  • one of said arcuate longitudinal edges of the anchoring plate is provided with a cut-out permitting to effect a longitudinal deformation of the plate in such direction as to move the mutually facing edges of the cut-out towards each other to thereby vary the radius of curvature of the arcuate anchoring plate.
