A dental implant system including an implant having an incisal portion for insertion into a alveolar receptor site formed in the jawbone to receive the implant, a collar having a beveled shape extending superiorly from the incisal portion with a smooth polished surface, a threadless cavity extending from the occlusal end of the implant partially into said embedded incisal portion with the cavity having a recessed groove adjacent the proximal end of the incisal portion, a removable healing cap adapted to be placed into the threadless cavity of said implant with said healing cap having a resilient shoulder projecting therefrom to engage said groove for forming a sealed interlock during an extended healing period and a single post abutment member for insertion into the threadless cavity of the implant after removal of the healing cap. An alternative embodiment of the implant system includes an implant having an incisal section with a vertical height of less than about 6mm for insertion into a very shallow bone receptor site formed in the jawbone of the patient, a plurality of projections laterally extending from a position near the apical end of the implant in a spider like arrangement so that they initially cover a broad subperiosteal surface adjacent mucosal tissue to give the implant lateral stability against lateral forces.
A press fit dental implant system comprising an implant having an apical portion with a straight section and a tapered section for insertion into a alveolar receptor site formed in the jawbone to receive the implant with the implant having an occlusal end and a proximal end, a collar having a beveled section extending superiorly from the apical portion, a threadless cavity extending interiorly from the occlusal end of the implant partially into its apical portion with the threadless cavity having a conical area within the beveled section of the collar and a recessed annular groove formed in said conical area below the occlusal end of the implant, a removable healing cap adapted to be placed into the threadless cavity of said implant with said healing cap having a beveled section contoured to match the beveled section in said collar, an annular resilient shoulder projecting from its beveled area to engage said recessed annular groove in said threadless cavity for forming a sealed interlock during an extended healing period, a domed top having at least one depressed area adapted to enable the top of the healing cap to be gripped mechanically or with the use of fingers for removal of the healing cap and a post abutment member for insertion into the threadless cavity of the implant after removal of the healing cap.
A dental implant system comprising an implant having an apical portion with a vertical height of less than about 6 mm for insertion into a very shallow bone receptor site formed in the jawbone of the patient, a coronal end section extending superiorly from the proximal end of the apical portion and a plurality of projections laterally extending from the apical portion in a spider like arrangement which initially cover a broad subperiosteal surface at the interface between the jawbone and mucosal tissue to give the implant lateral stability against lateral forces, wherein each of said plurality of projections have an outer tip at the terminal end of the projection extending downwardly at substantially ninety degrees from each of said projections and being adapted to engage openings formed in the jawbone surrounding said bone receptor site for providing lateral resistance to movement of the implant.
A dental implant system adapted to interlock a denture to a jawbone with the dental implant system comprising an implant having an incisal portion for insertion into an alveolar receptor site formed in the jawbone to receive the implant, a collar having a beveled section extending superiorly from the incisal portion, a threadless cavity extending from the occlusal end of the implant partially into said embedded incisal portion having a spherically shaped area adjacent the proximal end of the incisal portion and a male plug having a section adapted to be affixed to the denture with the male plug extending from the denture in alignment with the implant and a section for insertion into the cavity of the a vertical height of less than about 6 mm for insertion into a very shallow bone receptor site formed in the jawbone of the patient, a plurality of projections laterally extending from a position near the apical end of the implant in a spider like arrangement which initially cover a broad subperiosteal surface at the interface between the jawbone and mucosal tissue to give the implant lateral stability against lateral forces.
A dental implant system comprising an implant having an apical portion for insertion into a alveolar receptor site formed in the jawbone to receive the implant, a collar having a beveled section extending superiorly from the apical portion, a cavity extending from the occlusal end of the implant partially into said embedded apical portion for receiving a post abutment member and a distal section having a hollow area opening distally into the jawbone for forming an enclosure adapted for insertion of a bone morphogenic protein material wherein said distal section of the implant has a plurality of slitted projections surrounding said hollow area and extending lengthwise to permit the distal end to be crimped about the inserted bone morphogenic protein.
