A hybrid dental implant system is described and illustrated, which provides the dental profession with an implant system having a built-in contingency option by being able to go from a fixed implant modality to a retentive nonstress bearing removable one. The implant system includes a sleeve member adapted to be surgically inserted into the jawbone of a patient for alternatively receiving a fixed implant member or retentive implant member. The fixed implant member having a stress breaking device, is designed for supporting a crown and bridge prosthesis. The retentive implant member having an inciso-apically movable insert allows the underside of a denture to exert occlusal and masticatory forces upon the underlying soft gum tissue, thereby dissipating such forces before they are transmitted to the implant itself. Should an abutment tooth anterior or posterior to a fixed implant fail, the fixed implant member is simply screwed out of its retaining sleeve member and a retentive implant member is screwed into its place for retaining a full or partial denture.
A dental implant system for attaching a dental prosthesis to a jawbone underlying gum tissue, said implant system comprising a sleeve member to be secured within an upper portion of said jawbone, fixed implant means to be received by said sleeve member for securing said prosthesis, said fixed implant means including a fixed implant member received by said sleeve member and a fixed implant insert secured to said prosthesis and received by said fixed implant member to prevent movement of said fixed implant insert along the longitudinal axis of said sleeve member, and retentive implant means to be alternately received by said sleeve member upon removal of said fixed implant means for retaining said prosthesis while said prosthesis is at least partially supported by said gum tissue, said retentive implant means including a retentive implant member received by said sleeve member, and said retentive implant member including a retentive lip arranged circumscribing the interior surface thereof, and a retentive implant insert secured to said dental prosthesis and received by said retentive implant member for retaining said dental prosthesis while said prosthesis is being supported by said gum tissue, said retentive implant insert having a recess larger than said retentive lip for receiving said retentive lip therein to permit movement of said retentive implant insert along the longitudinal axis of said sleeve member.
