Abstract
Abstract A sterile kit for inserting an implant to which a dental prosthesis may be fastened, includes an implant (14) having a combined insertion tool/transfer pin (50) secured thereto by a screw (16), with a carrier (52) mating with the combined insertion tool/transfer pin to start the implant into a hole prepared therefor. The method of use includes taking an impression as soon as the implant is secured in the bone, thereafter removing the combined insertion tool/transfer pin, inserting a healing screw (38), and forming the model of the mouth and ultimate prosthesis and abutments in a laboratory while the several month healing process takes place.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
178 words
A method of providing an implant secured to a reconstruction site in a cavity in the bone of a patient, to which a prosthesis may be fastened, comprising: providing a sterile kit including an implant, an impression transfer pin secured to the implant and capable of use as an insertion tool for inserting the implant into a cavity provided therefor in the bone of a patient, a screw retaining the transfer pin to the implant, and a carrier for handling the aforementioned parts while beginning the process of inserting the implant into the bone; using the carrier, starting the implant into the cavity; dislodging the carrier from the other ones of said parts and removing the carrier from said site; inserting the implant into its intended position in the bone, selectively utilizing an additional tool as necessary; taking an impression of the site so as to permit preparing a model of the site; loosening said screw and removing said screw and said pin from said implant and from said site; and fastening a healing abutment to said implant.
Claim 2
Independent Claim
178 words
A method of providing an implant secured to a reconstruction site in a cavity in the bone of a patient, to which a prosthesis may be fastened, comprising: providing a sterile kit including an implant, an impression transfer pin secured to the implant and capable of use as an insertion tool for inserting the implant into a cavity provided therefor in the bone of a patient, a screw retaining the transfer pin to the implant, and a carrier for handling the aforementioned parts while beginning the process of inserting the implant into the bone; using the carrier, starting the implant into the cavity; dislodging the carrier from the other ones of said parts and removing the carrier from said site; inserting the implant into its intended position in the bone, selectively utilizing an additional tool as necessary; taking an impression of the site so as to permit preparing a model of the site; loosening said screw and removing said screw and said pin from said implant and from said site; and fastening a healing abutment to said implant.
Claim 3
Dependent Claim
20 words
A method according to claim 1 wherein said site is in a mouth and said prosthesis includes a replacement tooth.
Claim 4
Dependent Claim
51 words
A method according to claim 1 including, following said fastening step: allowing the site to heal while concomitantly, using said impression, preparing a prosthesis to be fastened to the implant; and when healing is complete, forming an incision at and removing said healing abutment, and fastening the prosthesis to the implant.
Claim 5
Independent Claim
224 words
A method of providing an implant secured in a hole in the maxilla or mandibular bone of a patient, to which a dental prosthesis may be fastened, comprising: providing a sterile kit including an implant, an impression transfer pin secured to the implant and capable of use as an insertion tool for inserting the implant into a hole provided therefor in the bone of a patient, a screw retaining the transfer pin to the implant, and a carrier for holding the aforementioned parts while beginning the process of inserting the implant into the bone; using the carrier, starting the implant into the hole; dislodging the carrier from the other ones of said parts and removing the carrier from the mouth; inserting the implant into its intended position in the bone, selectively utilizing an additional tool as necessary; taking an impression of the mouth so as to permit preparing a model of the mouth; loosening said screw and removing said screw and said transfer pin from said implant and from the mouth; fastening a healing abutment into said implant; thereafter allowing the gum to heal for at least one month while concomitantly, using said impression, preparing a prosthesis to be fastened to the implant; and when healing is complete, forming an incision at and removing said healing abutment, and fastening the prosthesis to the implant.
Claim 6
Independent Claim
224 words
A method of providing an implant secured in a hole in the maxilla or mandibular bone of a patient, to which a dental prosthesis may be fastened, comprising: providing a sterile kit including an implant, an impression transfer pin secured to the implant and capable of use as an insertion tool for inserting the implant into a hole provided therefor in the bone of a patient, a screw retaining the transfer pin to the implant, and a carrier for holding the aforementioned parts while beginning the process of inserting the implant into the bone; using the carrier, starting the implant into the hole; dislodging the carrier from the other ones of said parts and removing the carrier from the mouth; inserting the implant into its intended position in the bone, selectively utilizing an additional tool as necessary; taking an impression of the mouth so as to permit preparing a model of the mouth; loosening said screw and removing said screw and said transfer pin from said implant and from the mouth; fastening a healing abutment into said implant; thereafter allowing the gum to heal for at least one month while concomitantly, using said impression, preparing a prosthesis to be fastened to the implant; and when healing is complete, forming an incision at and removing said healing abutment, and fastening the prosthesis to the implant.
Claim 7
Dependent Claim
22 words
A method according to claim 4 wherein said step of fastening a healing abutment comprises inserting a healing screw into said implant.
Claim 8
Dependent Claim
82 words
An implant kit, comprising: a sterile package, said sterile package including: a screw; an implant; a transfer pin shaped so as to be able to function as an insertion tool in inserting said implant into a cavity prepared therefor in the bone of the patient, said transfer pin being secured to said implant by means of said screw; and a carrier disposed to engage said transfer pin so that manipulation of said carrier may start said implant into the cavity prepared therefor.
Claim 9
Dependent Claim
82 words
An implant kit, comprising: a sterile package, said sterile package including: a screw; an implant; a transfer pin shaped so as to be able to function as an insertion tool in inserting said implant into a cavity prepared therefor in the bone of the patient, said transfer pin being secured to said implant by means of said screw; and a carrier disposed to engage said transfer pin so that manipulation of said carrier may start said implant into the cavity prepared therefor.
Claim 10
Dependent Claim
37 words
An implant kit according to claim 6 wherein said implant is threaded, and said carrier engages said transfer pin so that rotation of said carrier imparts rotation to said implant so as to threadably engage the cavity.
