A method and apparatus for augmenting an endentulous alveolar ridge of a patient comprises the steps of (1) making a provisional denture-stent with a hollow space on the underside to account for the width, height and extent of the desired augmentation; (2) making an incision in, and reflecting, the gingiva where the augmentation is desired; (3) inserting bone graft material on the cortical plate; (4) suturing the gingiva; and (5) inserting the provisional stent over the bone graft material.

A submergible or non-submergible (âone stageâ) screw-type implant for use in the immediate post-extraction site of a patients tooth. In order to increase the ability of regenerated bone to anchor the implant, an upper portion of the implant has a preferably generally conical shape and has a plurality of spherical projections sintered to its outer surface to make it suitable for bone integration and retention. The lower portion of the implant has a cylindrical shape with threads extending over a portion thereof. A channel is located through the threads and is shaped so that one side forms a cutting edge that makes the lower portion of the implant self-tapping into the bone at the base of the tooth extension socket.

Biocompatible adhesive protective dressings, and methods of manufacturing and using the same, having properties suitable for use on moist tissues such as gingiva. The dressing may include a flexible sheet, e. g. a metal foil, with an irradiated gamma radiation sensitive adhesive on one surface. The properties of gamma sensitive adhesives are modified by exposure to gamma radiation so as to increase their adhesiveness and volume. The dressing may be applied to human or animal tissue to protect the tissue from the environment, and retain autogenous and other substances at the application site. The dressing may be used at surgical sites or wounds.

An improved assembly of a syringe and a nozzle tip for aspirating marrow blood from a surgical site and a method for using this improved syringe. The syringe includes a nozzle tip of special construction which has a sleeve portion, which fits on the free end of the barrel of the syringe, and a curved aspirating nozzle end. The nozzle tip includes a filter screen of preselected mesh size. A sufficient amount of marrow blood is aspirated through the curved aspirating nozzle end and the filter screen of the nozzle tip, thereby moving a preselected amount of marrow blood into the barrel of the syringe. The aspirated marrow blood then mixes with the granules of bone regeneration material disposed in the barrel of the syringe to form a viscous fluid mixture therein. The excess marrow blood, if any, is expelled through the curved aspirating nozzle end by applying a moderate manual pressure to the plunger of the syringe. After visual inspection of the formed viscous fluid mixture in the syringe, the nozzle tip is then manually removed from the syringe and the viscous fluid mixture is applied to a surgical site by applying manually pressure on the plunger of the syringe.

A method for preserving the alveolar ridge surrounding a presently extracted root socket by backfilling the socket with bone graft material and installing an implant in the root socket area either immediately before backfilling or after backfilling and a delay in which new bone is allowed to grow into the bone graft material. In one embodiment, the dental implant is installed apically into the root socket immediately following root extraction. The open area of the root socket surrounding the implant is then backfilled with bone graft material immediately after implant placement. The implant is preferably a threaded implant (but it can be a cylinder-type) which is placed approximately three to six millimeters apically to said root socket. The bone graft material comprises synthetic bone alloplast such as Bioplant HTR and is hydrated using the patients own blood obtained from the patients bleeding extraction socket after penetration but prior to insertion of the bone graft material and the implant into said root socket. As an alternate embodiment, the presently extracted root socket is filled with bone graft material and primary or non-primary closure of the extraction site is performed.
