Abstract
Abstract A thermoplastic, one-piece coping insert adapted for use with a dental implant anchoring means includes a shaft that fits into an opening in a dental implant, an abutment head joined to the shaft and adapted to conform to, and fit smoothly on, or in the top surface of the dental implant, a bendable restriction or groove to facilitate preferential bending of the insert at the restriction when the insert is heated to the softening temperature of a thermoplastic, and a relatively unbendable post atop the restriction for receiving and supporting a dental prosthesis such as one or more prosthetic teeth.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
126 words
A coping insert made of thermoplastic material, and adapted for use with an endosseous dental implant anchoring means comprising a shaft means adapted for insertion into a passage in said endosseous dental implant anchoring means; abutment head means atop, and joined to said shaft means, said abutment head means being adapted to conform to the top surface of said endosseous dental implant anchoring means; restriction means atop and joined to said abutment head means, said restriction means comprising a region of reduced cross-section having a size and shape sufficient to facilitate preferential bending at said restriction means when said coping insert is heated to the softening temperature of the thermoplastic; and atop, and joined to said restriction means, means for engaging and supporting dental prosthesis means.
Claim 2
Dependent Claim
126 words

Claim 6
Dependent Claim
133 words
A one-piece, thermoplastic coping insert adapted for use with an endosseous dental implant anchoring means comprising shaft means adapted for insertion into a passage in said endosseous dental implant anchoring means; abutment head means integrally joined to said shaft means, said abutment head means being adapted to conform to, and to abut the top surface of said endosseous dental implant anchoring means; means for engaging and supporting dental prosthesis means; and restriction means comprising a region of reduced cross-section linking the upper end of said abutment head means to the lower end of said engaging/supporting means, said restriction means being adapted to bend when said insert is heated to the softening temperature of the thermoplastic from which said insert is made without bending or distorting said abutment head means or said engaging/supporting means.
Claim 7
Dependent Claim
133 words
A one-piece, thermoplastic coping insert adapted for use with an endosseous dental implant anchoring means comprising shaft means adapted for insertion into a passage in said endosseous dental implant anchoring means; abutment head means integrally joined to said shaft means, said abutment head means being adapted to conform to, and to abut the top surface of said endosseous dental implant anchoring means; means for engaging and supporting dental prosthesis means; and restriction means comprising a region of reduced cross-section linking the upper end of said abutment head means to the lower end of said engaging/supporting means, said restriction means being adapted to bend when said insert is heated to the softening temperature of the thermoplastic from which said insert is made without bending or distorting said abutment head means or said engaging/supporting means.
Claim 8
Dependent Claim
38 words
The insert of claim 5 wherein said shaft means includes at least one groove means for facilitating removal of the portion of the shaft means below said groove means by severing said shaft means through said groove means.
