Abstract
Abstract A dental implant for anchoring attachments to the jawbone including an endosseous blade-like base embedded entirely within the bone tissue of the mandibular or maxillary ridge. A juxtaosseous support abutment is connected to the base by a shank having a neck portion spaced from the base and confined to the gingival. The base is received within a trough surgically cut into the jawbone and stabilized therein by cross-sectionally rounded enlargements of edge portions extending in mesial-distal directions relative to the shank.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
82 words
A dental implant for anchoring an attachment to a jawbone, comprising an endosseous blade type of base having two spaced edge portions, a shank projecting from one of the edge portions on which the attachment is supported, said edge portions being elongated relative to the shank in a mesial-distal direction and endosseous stabilizer means adapted to be embedded with the base entirely within said jawbone, including a rounded cross-sectional enlargement of the base continuously along the other of the spaced edge portions.
Claim 2
Dependent Claim
82 words
A dental implant for anchoring an attachment to a jawbone, comprising an endosseous blade type of base having two spaced edge portions, a shank projecting from one of the edge portions on which the attachment is supported, said edge portions being elongated relative to the shank in a mesial-distal direction and endosseous stabilizer means adapted to be embedded with the base entirely within said jawbone, including a rounded cross-sectional enlargement of the base continuously along the other of the spaced edge portions.
Claim 3
Dependent Claim
40 words
The combination of claim 1 wherein said one of the edge portions is provided with a tool receiving groove, whereby the other of the edge portions of the implant base may be seated within a trough precut into the jawbone.
Claim 4
Independent Claim
135 words
A device for permanently anchoring an attachment in the mouth of a patient, said device comprising an implanting portion in the form of a comparatively thin blade having an opening provided therein and a support portion adapted to have a juxtaosseous structure secured thereon, said implanting portion including a first edge from which the support portion extends, the first edge having a tool receiving groove spaced from the support portion through which the implanting portion is seated within a trough cut into the bone structure of the patient, and a second edge spaced from the first edge remote from the support portion, said second edge being formed entirely as a cross-sectionally rounded enlargement of the blade extending in a mesial-distal direction relative to the support portion to stabilize the implanting portion within the bone structure.
Claim 5
Independent Claim
135 words
A device for permanently anchoring an attachment in the mouth of a patient, said device comprising an implanting portion in the form of a comparatively thin blade having an opening provided therein and a support portion adapted to have a juxtaosseous structure secured thereon, said implanting portion including a first edge from which the support portion extends, the first edge having a tool receiving groove spaced from the support portion through which the implanting portion is seated within a trough cut into the bone structure of the patient, and a second edge spaced from the first edge remote from the support portion, said second edge being formed entirely as a cross-sectionally rounded enlargement of the blade extending in a mesial-distal direction relative to the support portion to stabilize the implanting portion within the bone structure.
Claim 6
Dependent Claim
22 words
The combination of claim 3 including a rigid stabilizer element extending laterally from the second edge in overlaying relation to said opening.
Claim 7
Dependent Claim
82 words
A dental implant for anchoring an attachment, comprising a blade having at least one opening formed therein, a shank projecting from the blade in offset relation to the opening, and a support connected to the shank to which the attachment is adapted to be secured, said blade including recessed side surfaces through which the opening extends, a first edge from which the shank projects and a second elongated edge remote from the shank that is a cross-sectionally rounded enlargement of the blade.
Claim 8
Dependent Claim
82 words
A dental implant for anchoring an attachment, comprising a blade having at least one opening formed therein, a shank projecting from the blade in offset relation to the opening, and a support connected to the shank to which the attachment is adapted to be secured, said blade including recessed side surfaces through which the opening extends, a first edge from which the shank projects and a second elongated edge remote from the shank that is a cross-sectionally rounded enlargement of the blade.
Claim 9
Dependent Claim
102 words
A bone implant having a thin blade portion adapted to be implanted in a jawbone and at least one integral neck portion projecting from said blade portion externally of the bone, said blade portion having at least one longitudinal end remote from said neck portion, two elongated edges extending in spaced relation to each other from said end transversely of the neck portion and a tool-receiving recess formed in one of said edges between the neck portion and said end, the other of the edges being formed by a continuous cross-sectionally rounded enlargement of the blade portion to produce a stabilizing effect.
Claim 10
Dependent Claim
102 words
A bone implant having a thin blade portion adapted to be implanted in a jawbone and at least one integral neck portion projecting from said blade portion externally of the bone, said blade portion having at least one longitudinal end remote from said neck portion, two elongated edges extending in spaced relation to each other from said end transversely of the neck portion and a tool-receiving recess formed in one of said edges between the neck portion and said end, the other of the edges being formed by a continuous cross-sectionally rounded enlargement of the blade portion to produce a stabilizing effect.
