Abstract
Abstract A horizontal and vertical sheer stress distributor for a dental prothesis implant is formed by a cylindrical member threadedly inserted into a jaw bone cavity. An angular disposed through bore in the root member secures an elongated bar projecting angularly downward from the root member into the jaw bone adjacent the cavity.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
88 words
A dental implant for a prothesis, comprising: a substantially cylindrical root member having threaded bores and having a die threaded exterior for threadedly entering a jaw bone cavity, a root member stabilizing bar projecting through one of the root member threaded bores for entering a patient's jaw bone adjacent the jaw bone cavity; a prothesis having a base cooperatively received by the root member socket; and, anchor means including a first screw in another of the root member threaded bores for securing the prothesis to said root member.
Claim 2
Dependent Claim
88 words
A dental implant for a prothesis, comprising: a substantially cylindrical root member having threaded bores and having a die threaded exterior for threadedly entering a jaw bone cavity, a root member stabilizing bar projecting through one of the root member threaded bores for entering a patient's jaw bone adjacent the jaw bone cavity; a prothesis having a base cooperatively received by the root member socket; and, anchor means including a first screw in another of the root member threaded bores for securing the prothesis to said root member.
Claim 3
Dependent Claim
29 words
A dental implant according to claim 1 and further including; an eccentrically bored and counterbored substantially cylindrical implant abutment and interposed between said root member and said prothesis base.
Claim 4
Dependent Claim
29 words
A dental implant according to claim 2 in which the anchor means further includes: a lock screw in said implant abutment for precluding angular rotation of said first screw.
Claim 5
Dependent Claim
125 words
A dental implant for a prothesis, comprising: a substantially cylindrical root member externally die threaded for threadedly entering a jaw bone cavity having one end portion forming an upwardly open socket and an eccentric upwardly open threaded bore and having a throughbore angularly inclined with respect to its longitudinal axis; a root member stabilizing bar projecting through the root member angularly inclined bore for entering a patient's jaw bone adjacent the jaw bone cavity; a prothesis having a base cooperatively received by the root member socket; an eccentrically bored and counterbored substantially cylindrical implant abutment interposed between said root member and said prothesis base; and, anchor means including a first screw in the root member threaded bore for securing the prothesis to said root member.
Claim 6
Dependent Claim
125 words
A dental implant for a prothesis, comprising: a substantially cylindrical root member externally die threaded for threadedly entering a jaw bone cavity having one end portion forming an upwardly open socket and an eccentric upwardly open threaded bore and having a throughbore angularly inclined with respect to its longitudinal axis; a root member stabilizing bar projecting through the root member angularly inclined bore for entering a patient's jaw bone adjacent the jaw bone cavity; a prothesis having a base cooperatively received by the root member socket; an eccentrically bored and counterbored substantially cylindrical implant abutment interposed between said root member and said prothesis base; and, anchor means including a first screw in the root member threaded bore for securing the prothesis to said root member.
Claim 7
Dependent Claim
29 words
A dental implant according to claim 4 in which the anchor means further includes: a lock screw in said implant abutment for precluding angular rotation of said first screw.
Claim 8
Dependent Claim
133 words
A dental implant for a prothesis, comprising: a substantially cylindrical root member externally die threaded for threadedly entering a jaw bone cavity having one ned portion forming an upwardly open socket and an eccentric upwardly open threaded bore and having a through bore angularly inclined at an acute angle with respect to its longitudinal axis; a root member stabilizing bar secured in and projecting through the root member angularly inclined bore for entering a patient's jaw bone adjacent the jaw bone cavity; a prothesis having a base cooperatively received by the root member socket; an eccentrically bored and counterbored substantially cylindrical implant abutment interposed between said root member and said prothesis base; and, anchor means including a first screw in the root member threaded bore for securing the prothesis to said root member.
Claim 9
Dependent Claim
133 words
A dental implant for a prothesis, comprising: a substantially cylindrical root member externally die threaded for threadedly entering a jaw bone cavity having one ned portion forming an upwardly open socket and an eccentric upwardly open threaded bore and having a through bore angularly inclined at an acute angle with respect to its longitudinal axis; a root member stabilizing bar secured in and projecting through the root member angularly inclined bore for entering a patient's jaw bone adjacent the jaw bone cavity; a prothesis having a base cooperatively received by the root member socket; an eccentrically bored and counterbored substantially cylindrical implant abutment interposed between said root member and said prothesis base; and, anchor means including a first screw in the root member threaded bore for securing the prothesis to said root member.
Claim 10
Dependent Claim
29 words
A dental implant according to claim 6 in which the anchor means further includes: a lock screw in said implant abutment for precluding angular rotation of said first screw.
