Abstract
Abstract A dental implant installation assembly which comprises three components, first, a dental implant having a biocompatible surface, a first end for being located in the alveolar cavity and a second end having formed therein a threaded opening, second a protective cap screw in the threaded opening in the implant, the screw having formed therein a female wrench-engaging cavity constructed and adapted to engage an insertable wrench, and, third, a holder having a gripping portion and a holding projection received in compression in the wrench-engaging cavity of the cap screw, the holder being releasable from the cap screw when the holder is bent relative to the head thereof is disclosed.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
217 words
A kit for performing dental implants comprising: a dental implant having a biocompatible surface, a first end which is constructed and adapted to be located within the interior of the alveolar cavity, and a second end which is adapted to be secured to a prosthesis, said second end having formed therein a threaded opening; an implant protective cap screw having a threaded portion constructed and adapted to be screwed into the threaded opening in the implant, and a head approximately the size of the second end of the dental implant for sealing the opening in said second end against tissue ingrowth during the initial healing period following installation of the implant into a patient, the head of the cap screw having formed therein a female wrench-engaging cavity constructed and adapted to engage an insertable wrench for turning the cap screw; and a holder for holding and installing the cap screw and dental implant, said holder comprising a gripping portion for permitting the dentist or surgeon to grip the holder, and a resilient cap screw holding projection constructed and configured to be received in compression in the wrench-engaging cavity of the cap screw for supporting the cap screw and implant during installation and for releasing the cap screw when the holder is bent relative to the head thereof.
Claim 2
Dependent Claim
217 words
A kit for performing dental implants comprising: a dental implant having a biocompatible surface, a first end which is constructed and adapted to be located within the interior of the alveolar cavity, and a second end which is adapted to be secured to a prosthesis, said second end having formed therein a threaded opening; an implant protective cap screw having a threaded portion constructed and adapted to be screwed into the threaded opening in the implant, and a head approximately the size of the second end of the dental implant for sealing the opening in said second end against tissue ingrowth during the initial healing period following installation of the implant into a patient, the head of the cap screw having formed therein a female wrench-engaging cavity constructed and adapted to engage an insertable wrench for turning the cap screw; and a holder for holding and installing the cap screw and dental implant, said holder comprising a gripping portion for permitting the dentist or surgeon to grip the holder, and a resilient cap screw holding projection constructed and configured to be received in compression in the wrench-engaging cavity of the cap screw for supporting the cap screw and implant during installation and for releasing the cap screw when the holder is bent relative to the head thereof.
Claim 3
Independent Claim
184 words
A method for installing dental implants which comprise a biocompatible surface, a first end which is constructed and adapted to be located within the interior of the alveolar cavity, and a second end which has formed therein a threaded opening and is adapted to be secured to a prosthesis, the method comprising the steps of: supporting a protective cap screw received in threaded opening in the implant, said cap screw having a head approximately the size of the second end of the dental implant for sealing the opening in said second end, the head of the cap screw having formed therein a female wrench-engaging cavity constructed and adapted to engage an insertable wrench for turning the cap screw, on a holder comprising a gripping portion for permitting the dentist or surgeon to grip the holder, and a resilient cap screw holding projection constructed and configured to be received in compression in the wrench-engaging cavity of the cap screw; inserting the implant thus supported into the alveolar cavity; and releasing the cap screw by bending the holder relative to the head of the cap screw.
Claim 4
Independent Claim
184 words
A method for installing dental implants which comprise a biocompatible surface, a first end which is constructed and adapted to be located within the interior of the alveolar cavity, and a second end which has formed therein a threaded opening and is adapted to be secured to a prosthesis, the method comprising the steps of: supporting a protective cap screw received in threaded opening in the implant, said cap screw having a head approximately the size of the second end of the dental implant for sealing the opening in said second end, the head of the cap screw having formed therein a female wrench-engaging cavity constructed and adapted to engage an insertable wrench for turning the cap screw, on a holder comprising a gripping portion for permitting the dentist or surgeon to grip the holder, and a resilient cap screw holding projection constructed and configured to be received in compression in the wrench-engaging cavity of the cap screw; inserting the implant thus supported into the alveolar cavity; and releasing the cap screw by bending the holder relative to the head of the cap screw.
Claim 5
Dependent Claim
166 words
A dental implant installation assembly comprising: a dental implant having a biocompatible surface, a first end which is constructed and adapted to be located within the interior of the alveolar cavity, and a second end which is adapted to be secured to a prosthesis, said second end having formed therein a threaded opening; an implant protective cap screw inserted into and threaded into the threaded opening in the implant, said screw having a head approximately the size of the second end of the dental implant, the head of the cap screw having formed therein a female wrench-engaging cavity constructed and adapted to engage an insertable wrench for turning the cap screw; and a holder having a gripping portion for permitting the dentist or surgeon to grip the holder by means of a resilient cap screw holding projection received in compression in the wrench-engaging cavity of the cap screw, said holder being releasable from the cap screw when the holder is bent relative to the head thereof.
Claim 6
