Definitions

  • the pericortical dental implant is in the form of a clamping device specifically adapted for attachment to either the mandible or maxilla wherein the clamp may be securely fastened to the bone structure to serve as a permanent base for the reception and mounting of an artificial tooth or in conjunction with other clamps to mount a partial or full denture.
  • the ultimate objective is to provide one or more artificial teeth which are finnly mounted within the mouth which will remain firm under the normal oral activities of the patient and which will appear natural to the sight.
  • dentures are not actually implanted but are merely fitted to the gums and may be held thereon as by adhesives or close interfitting with the gum. Many oral activities such as are frequently associated with eating of food substances such as com and sticky candy may cause the denture to become dislodged. Discomfort and inconvenience in proper denture hygiene are other common complaints lodged by denture wearers.
  • a pennanent bridge which consists of an artificial tooth supported by inlays that are cemented to the healthy natural teeth adjacent thereto.
  • This bridge generally provides a reasonably firm support for the artificial tooth, however it usually requires the removal of portions of the adjacent healthy teeth in order to provide the necessary structure for supporting the anchoring inlays and is not, therefore, entirely desirable in all cases.
  • Transosseous implants have also been used and these require burrowing into and through the bone and utilizing screw or pin fixation.
  • the required drilling through the'bone in this method often produces an intense postsurgical inflammatory response and accompanying bone resorption which may lead to the mobility of the implant when the same is subjected to the high stress of mastication, and consequently the followingloss of the implant.
  • a final form of implant is the subperiosteal implant which is applied beneath the mucosa in the periosteum which rests on the bone but without intraosseous engagement. While these implants have met with limited success, there are factors which mitigate against total successful use thereof. Since these implants are dependent upon fibrous tissue to hold them against the bone, and since fibrous tissue possesses a degree of elasticity, the net result is mobility of the implant when stress is applied thereto, thereafter followed by rejection. Maxillary subperiosteal implants are contraindicated in as much as the normal force of gravity will frequently prevent retention. It is also contraindicated in the maxilla because of the gross amount of cancellous bone present therein which will not support a subperiosteal implant due to rapid resorption of such cancellous bone.
  • periosteal implants usually required multiple surgical procedures (i.e., initial surgery for exposure of the mandible and obtaining an impression; followed by a healing period of up to 6 weeks, than a second surgical procedure consisting of reexposure of the mandible followed by implantation of the subperiosteal device).
  • the pericortical clamp of the instant invention herein disclosed obviates the difficulties inherent in the prior art methods disclosed above.
  • the clamp provides a firm, fixed base which more easily, quickly, and effectively supports a total or partial dental prosthesis.
  • a primary object of this invention is to provide means for mounting a dental prosthetic replacement which means is in the form of a clamp adapted to be fastened securely to either the mandible or maxilla of the patient.
  • Another object of the invention is to avoid the disadvantages common in the prior art of implantation by providing a clamping device that prevents any movement of the implant either lateral, torsional or longitudinal and yet will not place undue pressure upon the bone surface.
  • Still another object of this invention is to provide an inserter construction specifically adapted to place the implant clamp on the mandible or maxilla of the patient in a quick and simple operation.
  • Another object of the invention is to provide an implant device and inserter which may be readily applied by any dental surgeon and which includes a clamping device having two separate disengageable sections.
  • Another object of the invention is to provide an implant device formed of two sections, a clamp and an inserter, the latter being a tool to be used in inserting and tightening the clamp on the bone and which is then disengaged therefrom, leaving the implant clamp on the bone and about which the wound is closed.
  • Another object of the invention is to provide a fixed implant clamp which can be applied with minimum surgical dissection of soft tissue.
  • Still another object of the invention is to provide a firm, fixed implant base which can be attached to the maxilla.
  • Yet another object of the invention is to provide a dental implant device which is simple in construction, relatively cheap to manufacture and which is safe and efficient at all times and which may be removed at a later date if desired.

  • FIG. 13 is a perspective view similar to FIG. 12 showing the clamp portions being brought together.
  • the pericortical dental implant clamp of the present invention is shown generally at 10, and is formed in two pieces, the proximal half 11 and the distal half 12.
  • the clamp half portions are preferably formed from a biologically inert metal suitable for implantation in the human body.
  • Stainless steel, tantalum, or a cobalbchromium alloy commonly sold under the trademark Vitallium have been used as implant materials in recent years and would be acceptable for this particular application.
  • Each clamp half includes an upright vertical wall 13, 14 having a planer inner face.
  • the distal half 12 is provided with a pedestal 15 extending inwardly from the bottom of the vertical wall and the pedestal has elongated grooves 16 on the side sur faces thereof.
  • the front face of the pedestal is drilled and tapped as at 17.
  • the proximal clamp half 11 is formed with straddle arms 18 and 19 extending therefrom in a manner such as to fit closely about the pedestal 15 of the distal half 12.
  • Each of the straddle arms are tapered to an edge as at 19' and are formed on their inner surfaces with a rounded elongated tongue 20 as shown in FIG. 2.
  • each of the flat wall surfaces 13 and 14 are provided with relatively sharp bone-engaging spikes 21.
  • the proximal clamp half is formed with a smooth bore hole 22 adapted for alignment with the tapped hole 17 of the distal half.
  • a machine screw 23 serves to connect the two clamp halves together in a selected position of engagement about a bone as shown in FIG. 4. The screw 23 passes through the hole 22 and into threaded engagement with the tapped hole 17 in the distal half 12.
  • Another tapped hole 24 is placed centrally of the wall of the proximal half 11 for a purpose to be later described.
  • a truncated conical mounting post 25 is secured centrally on the bottom face of the pedestal 15 by means of a mounting screw 26. (See FIG. 4).
  • the mounting post could be formed integrally with the pedestal although in the preferred embodiment the same is removable since various configurations of posts could be used if desired.
  • a square cross section post may be found desirable in certain applications.
  • An artificial tooth structure T may be cemented onto the mounting post 25 with the use of conventional dental cements.
  • other means for locking the tooth structure to the mounting post may be employed such as a resilient detent member within the recess of the artificial tooth adapted to snap into a groove provided on the surface of the mounting post (not shown).
  • the clamp 10 may be applied to either the mandible or maxilla of the patient and as shown in FIGS. 3 and 4 is placed on the mandible for mounting of an artificial tooth to take the place of a tooth that has been removed and is surrounded by natural teeth.
  • the detailed procedure for placing of the clamp will be described later herein in greater detail, however generally the application requires surgical procedures in order to expose the mandible and requires some scraping of the periosteum in order to provide intimate contact between the wall faces of the clamp and the bone surface.
  • the clamp is pushed down so that the face of the pedestal 15 is directly against the top surface of the bone and forces are applied to cause a tight gripping of the bone by the wall faces 13 and 14.
  • the spikes 21 will imbed themselves into the bone in order to provide a tight purchase and to prevent slippage of the clamp.
  • the spikes are designed to be of a length as not to interfere or impinge upon the neurovascular bundle which runs through the mandible or maxilla.
  • the normal restorative powers of the body cause rebuilding and growth of the tissues and, as shown in FIG. 4, the normal gum line G will extend around and above the clamp so as to completely cover the same.
  • the post 25 may be adjusted slightly in the vertical direction after completion of the surgery in order to make proper correction of the 5 bite and proper mating with the teeth on the opposite bone.
  • the clamp may be fabricated in various widths in' order to accommodate two or even more mounting posts.
  • the mounting posts may be angled with respect to the pedestal for areas such as the retromolar areas where curvature of the ridge crest may dictate such use.
  • Such angled posts may also be useful in achieving parallelism with a mesially or distally tilted tooth or implant abutment.
  • Various combinations of one or more implant clamps may be used for proper mounting of complete dentures.
  • the INSERTER While the pericortical implant clamp could be applied to the bone by hand and the screw 23 tightened with a conventional screwdriver, a novel inserting tool has been developed which greatly speeds application of the clamp and achieves a tighter and more secure purchase of the clamp on the bone.
  • This inserter is a modification of the bone clamp application tool shown in my earlier US. Pat. No. 3,477,429.
  • the improved inserter is shown in FIGS. 5 and 6 and is designated generally at 30.
  • the various components of the inserter may be formed of stainless steel or other suitable metallic material that can easily be sterilized.
  • the inserter consists of a generally cylindrical, although slightly tapered, barrel portion 31 having a flat end wall from which extend spring arms 32 and 33.
  • each of the spring arms may be part of a one-piece U-shaped construction and due to their length and design, are resilient and may be biased outwardly at their free end in a manner described in greater detail later herein.
  • the inner face of each of the spring arms is provided with a V-groove or guide track 34 for a portion of its length and terminating in a front shoulder stop 35.
  • the barrel has a through cutout 36 and the interior of the barrel defined within the cutout has a rear wall 37 and a front wall 38.
  • the rear wall 37 is axially bored as at 39 and the front wall 38 is bored at 40 to provide an opening coaxial with the opening 39 for reception of a hollow jack shaft 41.
  • the jack shaft is rotatable within the barrel and is retained from axial movement with respect to the barrel by means of retaining clips 42 and 43 received within annular grooves in the shaft.
  • a knurled hand knob 44 is secured to the rear end of the jack shaft in order to provide a convenient surface for manual rotation of the shaft.
  • the forward portion of the shaft is'formed with screw threads 45.
  • a screwdriver 46 is received within the axial bore of the jack shaft 41 and may be slid forwardly and rearwardly in an axial direction but is frictionally held in position by means of a friction grommet 47 mounted within the jack shaft 41.
  • the rear end of the shaft of the screwdriver is provided with a hand knob 48 having a knurled surface and being slightly smaller in diameter than the knob 44.
  • the forward end of the screwdriver is provided with a conventional flat blade configuration as shown at 49.
  • the end 45 of the jack shaft having threads thereon is threadedly received in a jack nut 50 located between the spring arms 32 and 33 and has an-upstanding front flange 51 mounted at the front end thereof which has flat, parallel side portions that are engageable against the spring arms in order to prevent rotation of the jack nut.
