Sinus dental implant stabilizer

Claim 1

A sinus dental implant assembly stabilizer comprising a) an externally threaded elongated implant having an internal recess at one end, b) an insert removably fitting into said recess, and having a head projecting laterally beyond said recess, c) a washer capable of being removably held in fixed position by said implant and insert, and d) a nut having an opening to fit over said implant of a size and internally threaded for engagement with said implant, said nut being provided with means to hold said nut securely when said implant is being inserted into said nut.

Claim 6

A method of fixing a dental implant into a cavity bounded by sinus bone and tissue wherein the cavity is filled with particulate dental graft material which eventually is replaced by bone secured to the sinus bone, and placing a dental implant in said cavity for affixation to said bone, which comprises a) forming a bony infracture lateral window in the sinus bone from outside to within the sinus bone cavity, b) forming a first essentially vertical opening in the sinus bone from outside to within the sinus bone cavity, c) holding a nut within said cavity, said nut having a second opening in registry with the first opening in said bone, d) inserting through said first opening and second registered opening the dental implant of a dental implant stabilizer assembly so as to secure said implant to said nut, said implant at an end having a recess into which an insert is removably fitted, said insert having a head projecting laterally beyond said recess, said assembly further including a washer capable of being removably held in fixed position by said implant and insert, the insertion of said implant continuing until said bone is held between said nut and washer, e) partially filling said cavity with particulate dental graft material, f) restoring the bony infracture lateral window to an initial position, g) allowing the structure to set for a prolonged period of time, and h) thereafter removing from the end of said implant the inserted washer, whereby the formation of bone within said cavity and affixation of said implant to such formed bone are effected simultaneously.

Claim 7

A method of fixing a dental implant into a cavity bounded by sinus bone and tissue wherein the cavity is filled with particulate dental graft material which eventually is replaced by bone secured to the sinus bone, and placing a dental implant in said cavity for affixation to said bone, which comprises a) forming a bony infracture lateral window in the sinus bone from outside to within the sinus bone cavity, b) forming a first essentially vertical opening in the sinus bone from outside to within the sinus bone cavity, c) holding a nut within said cavity, said nut having a second opening in registry with the first opening in said bone, d) inserting through said first opening and second registered opening the dental implant of a dental implant stabilizer assembly so as to secure said implant to said nut, said implant at an end having a recess into which an insert is removably fitted, said insert having a head projecting laterally beyond said recess, said assembly further including a washer capable of being removably held in fixed position by said implant and insert, the insertion of said implant continuing until said bone is held between said nut and washer, e) partially filling said cavity with particulate dental graft material, f) restoring the bony infracture lateral window to an initial position, g) allowing the structure to set for a prolonged period of time, and h) thereafter removing from the end of said implant the inserted washer, whereby the formation of bone within said cavity and affixation of said implant to such formed bone are effected simultaneously.
