Abstract
A dental implant for anchoring attachments to the jawbone including a flat base embedded entirely within the bone tissue of the mandibular or maxillary ridge. A support head is connected to the base by a shank having a necked down portion spaced from the base and confined to the gingival. A stabilizer formation spaced lingually from the base in overlying relation to a rectangular opening formed therein, is connected to the edge portion of the base from which the shank projects.
Claims6
In a dental implant for anchoring an artificial tooth in the jawbone of a patient, having a substantially flat base embedded in the bone tissue and at least one substantially non-planar support connected to the base and projecting from the gingival line along a root axis of the tooth, the improvement including a shank extending between said support and the base along said root axis having a neck portion projecting from the ridge crest of the bone tissue toward said gingival line, said neck portion being dimensionally smaller than the base in a cross-sectional plane intersecting the lingual and buccal surfaces of the jawbone, said base including spaced edge portions extending in a mesial-distal direction from the shank transversely of the root axis and an intermediate portion, said intermediate portion being cross-sectionally thinner than the edge portions and having at least one opening formed therein, and a relatively rigid stabilizer connected to and spaced liqually from the base, said stabilizer being connected to one of the edge portions from which the shank projects and aligned with said opening in the base.
A dental implant for anchoring an artificial tooth in alignment with a root axis, comprising a blade type of base having spaced edge portions, a shank projecting from one of the edge portions of the base along said root axis and stabilizer means adapted to be embedded with the base entirely within a jawbone and extending only from said one of the edge portions laterally of the base and in offset relation to the shank for resisting turning moments applied to the base, said stabilizer means thereby increasing the spacing of the center of mass of the embedded implant relative to said one of the edge portions.
A dental implant for anchoring an artifical tooth in alignment with a root axis, comprising a blade type of base having an edge portion, a shank projecting from said edge portion of the base along said root axis, a support connected to the shank on which the artificial tooth is adapted to be seated, and stabilizer means extending laterally from the base and adapted to be embedded therewith entirely within a jawbone for establishing a center of mass enhancing resistance to turning moments applied to the base, said stabilizer means including a rigid element extending only from said edge portion of the base whereby the spacing of the center of mass relative to said edge portion is increased in offset relation to the root axis.
