Abstract

Abstract A dental implant system utilizing a root which is fixed to the jawbone. A post is supported to the root and has a crown connected thereto. A member is provided for cushioning forces applied to the crown and a stop is also included to limit the movement between the crown and the root upon the application of force to the crown.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 240 words
A dental implant system intended for placement in an alveolus of the jaw bone comprising: a. a root including means intended for fixing the root to the jawbone said root having a portion intended for extending into the alveolus, said root further including a surface having a transverse dimension in relation to said root portion extending into the alveolus, said root surface intended for being adjacent the outer surface of the jawbone; b. a post including means for supporting said post to said root; c. a crown connected to said post; d. means for cushioning forces applied to said crown, said cushioning means including a resilient member having a first element placed between said post and said portion of said root intended for extending into the alveolus; and a second element placed adjacent said surface of said root adjacent the outer surface of the jawbone; and e. means for attenuating relative movement between said crown and said root upon the application of force to said crown, said attenuating means including a spacer disposed adjacent said second element of said resilient member such that said second element of said resilient member lies between said surface of said root adjacent the outer surface of the jawbone and said spacer, said spacer including a surface intended for being capable of directly contacting said root surface adjacent the outer surface of said jawbone, thereby attenuating the relative movement between said crown and said root.
Claim 2
Dependent Claim 240 words
A dental implant system intended for placement in an alveolus of the jaw bone comprising: a. a root including means intended for fixing the root to the jawbone said root having a portion intended for extending into the alveolus, said root further including a surface having a transverse dimension in relation to said root portion extending into the alveolus, said root surface intended for being adjacent the outer surface of the jawbone; b. a post including means for supporting said post to said root; c. a crown connected to said post; d. means for cushioning forces applied to said crown, said cushioning means including a resilient member having a first element placed between said post and said portion of said root intended for extending into the alveolus; and a second element placed adjacent said surface of said root adjacent the outer surface of the jawbone; and e. means for attenuating relative movement between said crown and said root upon the application of force to said crown, said attenuating means including a spacer disposed adjacent said second element of said resilient member such that said second element of said resilient member lies between said surface of said root adjacent the outer surface of the jawbone and said spacer, said spacer including a surface intended for being capable of directly contacting said root surface adjacent the outer surface of said jawbone, thereby attenuating the relative movement between said crown and said root.
Claim 3
Dependent Claim 77 words
The dental implant system of claim 1 in which said spacer further includes a first portion disposed between said crown and said first element of said resilient member, and includes a second portion lying closer to said root surface adjacent the outer surface of the jawbone than said first portion of said spacer, said second portion of said spacer including said surface being capable of directly contacting said root surface adjacent the outer surface of the jawbone.
Claim 4
Dependent Claim 40 words
The dental implant system of claim 2 in which said surface of said spacer second portion lies adjacent to and apart from said root surface adjacent the outer surface of the jawbone in the absence of force upon said crown.
Claim 5
Dependent Claim 22 words
The dental implant system of claim 1 in which said first and second elements of said resilient member form an integral unit.
Claim 6
Dependent Claim 37 words
The dental implant system of claim 1 in which said post further includes a flange lying adjacent said spacer, and a crevice between said flange and said post, said post being movable in relation to said root.
Claim 7
Dependent Claim 21 words
The dental implant system of claim 1 in which said root further comprises means for holding artificial bone to said root.
Claim 8
Dependent Claim 29 words
The dental implant system of claim 6 in which said means for holding artificial bone to said root comprises a recessed portion formed on said root adjacent the jawbone.
Claim 9
Dependent Claim 125 words
A dental implant system for placement in an aveolus of the jaw comprising: a. a root including means intended for fixing the root to the jawbone; said root having a first portion intended for extending into the aveolus and a second portion outside the aveolus adjacent the jaw bone; b. a post including means for supporting said post to said root; c. a crown connected to said post; d. means for cushioning forces applied to said crown; and e. means for holding artificial bone to said second portion of said root adjacent the jawbone outside of the aveolus, said holding means comprising a lip formed on said root and extending radially from said root, and artificial bone held to said root by said holding means.
Claim 10
Dependent Claim 125 words
A dental implant system for placement in an aveolus of the jaw comprising: a. a root including means intended for fixing the root to the jawbone; said root having a first portion intended for extending into the aveolus and a second portion outside the aveolus adjacent the jaw bone; b. a post including means for supporting said post to said root; c. a crown connected to said post; d. means for cushioning forces applied to said crown; and e. means for holding artificial bone to said second portion of said root adjacent the jawbone outside of the aveolus, said holding means comprising a lip formed on said root and extending radially from said root, and artificial bone held to said root by said holding means.
Claim 11
Dependent Claim 30 words
The dental implant system of claim 8 in which said means for holding artificial bone to said root additionally comprises a recessed portion formed on said root adjacent the jawbone.
