Abstract
Abstract A dental implant includes a generally longitudinal body having a first portion for receiving an artificial tooth and a second portion for engaging the hard tissue of a person receiving the implant, the second portion having coronal end adjacent the first portion, and a apical end, and a surface characterized by a texture compatible with osseointegration of hard tissue with the second portion, the second portion having a contour adjacent its coronal end having a generally saddle shaped configuration so that upon implantation, the surface of the second portion extends further from the apical end between adjacent teeth than it does in front or behind the artificial tooth.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
108 words
A dental implant comprising: a generally longitudinal body having a first portion for receiving an artificial tooth and a second portion for engaging the hard tissue of a person receiving the implant, the second portion having coronal end adjacent the first portion, and a apical end, and a surface characterized by a texture compatible with osseointegration of hard tissue with the second portion, the second portion having a contour adjacent its coronal end having a generally saddle shaped configuration so that upon implantation, the surface of the second portion extends further from the apical end between adjacent teeth than it does in front or behind the artificial tooth.
Claim 2
Dependent Claim
108 words
A dental implant comprising: a generally longitudinal body having a first portion for receiving an artificial tooth and a second portion for engaging the hard tissue of a person receiving the implant, the second portion having coronal end adjacent the first portion, and a apical end, and a surface characterized by a texture compatible with osseointegration of hard tissue with the second portion, the second portion having a contour adjacent its coronal end having a generally saddle shaped configuration so that upon implantation, the surface of the second portion extends further from the apical end between adjacent teeth than it does in front or behind the artificial tooth.
Claim 3
Dependent Claim
108 words
A dental implant having a tooth attaching part for receiving an artificial tooth, and a root that is adapted to be placed into a hole drilled in a patients jaw, to replace the root of a tooth, the root of the implant having a surface texture that promotes attachment of bone tissue of the jaw to the surface of the implant, the surface extending from one end (apical) of the implant towards the tooth attaching part and having a contoured shape that promotes additional bone attachment between the teeth, and less attachment in front of and behind the teeth, to simulate natural greater bone growth between the teeth.
Claim 4
Dependent Claim
108 words
A dental implant having a tooth attaching part for receiving an artificial tooth, and a root that is adapted to be placed into a hole drilled in a patients jaw, to replace the root of a tooth, the root of the implant having a surface texture that promotes attachment of bone tissue of the jaw to the surface of the implant, the surface extending from one end (apical) of the implant towards the tooth attaching part and having a contoured shape that promotes additional bone attachment between the teeth, and less attachment in front of and behind the teeth, to simulate natural greater bone growth between the teeth.
Claim 5
Dependent Claim
83 words
A dental implant having a tooth attaching coronal end and an apical end for implanting in hard tissue of a patient, and buccal, lingual, mesial proximal, and distal proximal surfaces, comprising: a hard tissue receptive surface extending from an apical end of the implant towards a coronal end, the hard tissue receptive surface on at least one of the distal proximal, and mesial proximal surfaces being longer than the hard tissue receptive surface on at least one of the buccal and lingual surfaces.
Claim 6
Dependent Claim
83 words
A dental implant having a tooth attaching coronal end and an apical end for implanting in hard tissue of a patient, and buccal, lingual, mesial proximal, and distal proximal surfaces, comprising: a hard tissue receptive surface extending from an apical end of the implant towards a coronal end, the hard tissue receptive surface on at least one of the distal proximal, and mesial proximal surfaces being longer than the hard tissue receptive surface on at least one of the buccal and lingual surfaces.
Claim 7
Dependent Claim
25 words
The dental implant of claim 3 in which the hard tissue receptive surface comprises microscopic surface features for promoting hard tissue attachment, and/or reducing resorption.
Claim 8
Dependent Claim
15 words
The dental implant of claim 4 in which the hard tissue receptive surface is rough.
Claim 9
Dependent Claim
15 words
The dental implant of claim 5 in which the hard tissue receptive surface is etched.
Claim 10
Dependent Claim
15 words
The dental implant of claim 5 in which the hard tissue receptive surface is grit-blasted.
Claim 11
Dependent Claim
20 words
The dental implant of claim 5 in which the hard tissue receptive surface is coated with a bone receptive coating.
Claim 12
Dependent Claim
25 words
The dental implant of claim 3 in which the hard tissue receptive surface comprises macroscopic surface features for promoting hard tissue attachment, and/or educing resorption.
Claim 13
Dependent Claim
15 words
The dental implant of claim 9 in which the hard tissue receptive surface is threaded.
Claim 14
Dependent Claim
18 words
The dental implant of claim 9 in which the hard tissue receptive surface is a stepped conical surface.
Claim 15
Dependent Claim
16 words
The dental implant of claim 3 comprising a collar adjacent a coronal end of the implant.
Claim 16
Dependent Claim
14 words
The dental implant of claim 12 in which the collar has a smooth surface.
Claim 17
Dependent Claim
34 words
The dental implant of claim 12 in which the collar extends further towards the apical end of the implant at the buccal and lingual surfaces that at the distal proximal and mesial proximal surfaces.
Claim 18
Dependent Claim
28 words
The dental implant of claim 14 in which the collar has a substantially constant width, measured from the apical end of the implant towards the coronal end thereof.
Claim 19
Dependent Claim
15 words
The dental implant of claim 12 comprising a tooth mounting part at the coronal end.
