Prosthetic superstructure

A prosthetic superstructure for use with a dental prosthesis, said superstructure comprising a locking device accommodated in said dental prosthesis and adapted to be secured to a connecting part of an implant, said locking device comprising locking parts movable into a locking position in locking relationship with said connecting part and an unlocking position out of locking relationship with said connecting part, an adjustment device for moving said locking device into said locking and said unlocking positions, and an actuating device disposed in a false tooth on the dental prosthesis for actuating said adjustment device, said locking device being accommodated in a first false tooth of the dental prosthesis, said adjustment device comprising a shaft which passes through a second false tooth of said dental prosthesis, said second tooth being juxtaposed to said first false tooth, said false tooth in which said actuating device is accommodated being juxtaposed to said second false tooth.

A prosthetic superstructure for use with a dental prosthesis, said superstructure comprising a locking device accommodated in said dental prosthesis and adapted to be secured to a connecting part of an implant, said locking device comprising two locking parts movable into a locking position in locking relationship with said connecting part and an unlocking position out of locking relationship with said connecting part, said two locking parts having juxtaposed sides each having juxtaposed generally semi-circular recesses which together form a generally cylindrical recess when said two locking parts are in their locking position, an adjustment device for moving said locking device into said locking and said unlocking positions, said adjustment device including an adjustment shaft having a cam section extending into said generally cylindrical recess, and an actuating device disposed in a false tooth on the dental prosthesis for actuating said adjustment device.

A prosthetic superstructure for use with a dental prosthesis, said superstructure comprising a locking device accommodated in said dental prosthesis and adapted to be secured to a connecting part of an implant, said locking device comprising two locking parts movable into a locking position in locking relationship with said connecting part and an unlocking position out of locking relationship with said connecting part, said locking device comprising a housing having an opening, said locking device further comprising pivot means for pivotably supporting said two locking parts in said housing for pivotal movement in opposite directions between said locking position and said unlocking position, said two locking parts each having a cam portion, an adjustment device for moving said locking device into said locking and said unlocking positions, said adjustment device including an adjusting shaft mounted on said housing and having a cam section engageable with said cam portion of said two locking parts, whereby rotation of said adjusting shaft effects movement of said two locking parts between said locking and said unlocking position, and an actuating device disposed in a false tooth on the dental prosthesis for actuating said adjustment device.

A prosthetic superstructure for use with a dental prosthesis, said superstructure comprising a locking device accommodated in said dental prosthesis and adapted to be secured to a connecting part of an implant, said locking device comprising two locking parts movable into a locking position in locking relationship with said connecting part and an unlocking position out of locking relationship with said connecting part, said locking device including a housing and pivotal supports on said housing and on said two locking parts for pivotally supporting said locking parts on said housing for movement between said locking and said unlocking position, said pivotal supports including recesses in said locking parts, said recesses having the configuration of a partial cylinder which extends over the width of the locking parts, said housing having projections having the configuration of a partial cylinder corresponding to the partial cylindrical configuration of said recesses such that said recesses receive said projections to provide a pivotal relationship therebetween, an adjustment device for moving said locking device into said locking and said unlocking positions, and an actuating device disposed in a false tooth on the dental prosthesis for actuating said adjustment device.

A prosthetic superstructure for use with a dental prosthesis, said superstructure comprising a locking device accommodated in said dental prosthesis and adapted to be secured to a connecting part of an implant, said locking device comprising locking parts movable into a locking position in locking relationship with said connecting part and an unlocking position out of locking relationship with said connecting part, an adjustment device for moving said locking device into said locking and said unlocking positions, and an actuating device disposed in a false tooth on the dental prosthesis for actuating said adjustment device, said actuating device including a fork-shaped abutment member and a carrier moveable relative to said fork-shaped abutment member.

A prosthetic superstructure for use with a dental prosthesis, said superstructure comprising a locking device accommodated in a first false tooth of said dental prosthesis and adapted to be secured to an anchoring part in the mouth of the person on which the dental prosthesis is used, said locking device comprising locking parts movable into a locking position in locking relationship with said anchoring part and an unlocking position out of locking relationship with said anchoring part, and an actuating device disposed in a second false tooth on the dental prosthesis, said actuating device having an operable relationship with said locking means for effecting actuation of said locking device between said locking position and said unlocking position.
