Expansible dental implant

Claim 2

An expansible dental implant having a dental support portion and an implant portion adapted to be embedded in the jaw bone, said implant portion comprising at least two flat, juxtaposed, contacting members at least one of which is movable relative to the other in a plane parallel to the plane of the other member from an initial position in which the implant portion has a minimum effective width to an expanded position in which the width of the implant portion is substantially increased for anchorage thereof in the jaw bone.

Claim 3

The device as defined in claim 1 wherein said implant portion members are slidably connected together for sliding movement in relatively opposite directions.

Claim 4

The device as defined in claim 2 wherein said dental support portion comprises at least two members rigidly connected to the respective two members of said implant portion.

Claim 5

The device as defined in claim 1 wherein said implant portion members are pivotally connected together.

Claim 6

The device as defined in claim 4 wherein said dental support portion comprises at least two members rigidly connected to the respective two members of said implant portion.

Claim 7

The device as defined in claim 1 wherein one of said implant portion members comprises a fixed guide member, the other of said members being slidable in and projectable outwardly from said guide member.

Claim 8

In an expansible dental implant having a dental support portion and an implant portion adapted to be embedded in the jaw bone, the combination of at least two juxtaposed, smooth, flat, parallel contacting blade-shaped members and means slidably connecting the same together for sliding movement in parallel planes and in relatively opposite directions from an initial position in which the implant portion has a minimum effective width to an expanded position in which the width of the implant portion is substantially increased for anchorage thereof to the jaw bond.

Claim 9

In an expansible dental implant having a dental support portion and an implant portion adapted to be embedded in the jaw bone, the combination of at least two juxtaposed, smooth, flat, parallel contacting blade-shaped members and means slidably connecting the same together for sliding movement in parallel planes and in relatively opposite directions from an initial position in which the implant portion has a minimum effective width to an expanded position in which the width of the implant portion is substantially increased for anchorage thereof to the jaw bond.

Claim 10

The device as defined in claim 7 wherein said slidable connecting means comprise a pin carried by one of said members and slidable in a slot formed in the other member.

Claim 11

The device as defined in claim 7 together with a third blade-shaped member juxtaposed to the two first mentioned members so as to provide two outside members and an inside member slidably interposed therebetween, said slidable connecting means comprising a transverse pin extending between and rigidly connecting said two outside members together, said inside member being formed with a slot slidably receiving said pin.

Claim 12

The device as defined in claim 7 wherein each of said blade-shaped members has a horizontally elongated implant portion and a dental support portion projecting vertically from one end of the implant portion so that the dental support portions are spaced apart longitudinally in the initial contracted position of the implant portions and also that the implant portions may be urged to the expanded position by drawing the dental support portions together.

Claim 13

In an expansible dental implant having a dental support portion and an implant portion adapted to be embedded in the jaw bone, the combination of two flat, juxtaposed, contacting blade-shaped members having a substantially L-shaped configuration and including a substantially horizontal implant portion and a substantially vertical dental support portion integral therewith, and a pin pivotally connecting said members together at a point between the implant Portions and the dental support portions thereof so that the dental support portions are spaced apart when the implant portions are in the initial contracted position and also that the implant portions may be urged to the expanded position in planes parallel to their flat surfaces by drawing the dental support portions together.

Claim 14

In an expansible dental implant having a dental support portion and an implant portion adapted to be embedded in the jaw bone, the combination of two flat, juxtaposed, contacting blade-shaped members having a substantially L-shaped configuration and including a substantially horizontal implant portion and a substantially vertical dental support portion integral therewith, and a pin pivotally connecting said members together at a point between the implant Portions and the dental support portions thereof so that the dental support portions are spaced apart when the implant portions are in the initial contracted position and also that the implant portions may be urged to the expanded position in planes parallel to their flat surfaces by drawing the dental support portions together.

Claim 15

The device as defined in claim 11 together with means provided in said dental support portions for locking the same together in the expanded position of the device.

Claim 16

The device as defined in claim 11 which is further characterized in that the implant portions of said members are elongated and longitudinally curved, extending in relatively opposite directions from said pivot pin.

Claim 17

In an expansible dental implant, the combination of a fixed guide member adapted to be embedded in the jaw bone and provided with a curved, flat, open-ended track, and a curved, flat insert member slidable in the track of said guide member, the length of said insert member being greater than that of the guide member track so that in its inserted position the insert member projects at both ends from the guide member, one projecting end portion of the insert member constituting a dental support portion and the other projecting end portion thereof constituting an implant portion for embedding in the jaw bone.

Claim 18

In an expansible dental implant, the combination of a fixed guide member adapted to be embedded in the jaw bone and provided with a curved, flat, open-ended track, and a curved, flat insert member slidable in the track of said guide member, the length of said insert member being greater than that of the guide member track so that in its inserted position the insert member projects at both ends from the guide member, one projecting end portion of the insert member constituting a dental support portion and the other projecting end portion thereof constituting an implant portion for embedding in the jaw bone.

Claim 19

The device as defined in claim 14 wherein said guide member is also provided with a second curved open-ended track one end of which is confluent with one end of the first mentioned track, the two tracks curving in opposite directions from their confluent end, and a second curved insert member slidable in the second track of the guide member.

Claim 20

The device as defined in claim 14 together with a curved guide tube secured to said guide member and having open ends, and a curved stabilizing pin slidably inserted in said guide tube, said pin being projectable from the guide tube into the jaw bone.
