Abstract
A second-stage healing abutment for forming and preserving in the mucosa above a dental implant a transmucosal opening large enough to receive an artificial tooth which faithfully replicates a natural tooth being restored, and a companion transfer coping having identical transmucosal portions for forming in a laboratory model a faithful replica of the transmucosal opening in which to fabricate the artificial tooth, and methods of using the same.
Claims19
A method of preparing an anatomically correct dental restoration for installation on a natural or artificial root comprising the steps of preparing in the gingiva overlying said root an opening to the gingival aspect of said root said opening having at the gingival surface substantially the full cross-sectional size and non-round shape of a natural tooth emerging through said gingiva from said root, making a model of said gingiva replicating substantially identically said opening and said gingival aspect of sad root, forming on said model an artificial tooth substantially replicating in said opening the emergence shape and contours of said natural tooth, and installing said artificial tooth on said root.
A healing member for use in dental implant surgery following placement of a dental implant fixture at an edentulous site in a patient's jawbone, said member having a transmucosal section for establishing through the mucosa overlying said jawbone at said site an opening exposing the sub-gingival end of said fixture, said section having at one end substantially the cross-sectional size and shape of said end of said fixture, said section having at its other end substantially the cross-sectional size and non-round shape of a natural tooth at said site where said tooth emerges from said mucosa, and means to attach said one end of said member to said fixture.
A transfer coping for use in making a rigid model of a patient's edentulous jawbone site containing root means in the jawbone and an opening through the overlying mucosa exposing the gingival end of said root means, which opening has at one end substantially the cross-sectional size and shape of said gingival end and at its other end substantially the cross-sectional size and non-round shape of a natural tooth at said site where said tooth emerges through the surface of said mucosa, said coping having a transmucosal section sized and having a non-round shape so as to substantially mate with the size and non-round shape of said opening and a supragingival section adapted for embedment in resilient modelling material, said supragingival section including means to restrain said coping against turning in said modelling material, and means to attach said transmucosal section to said root means within said opening.
A set of components for use in making an artificial tooth which emulates a natural tooth missing from a patient's jawbone site containing root means in said jawbone, said set including a healing member having a first transmucosal section for establishing in the mucosa overlying said jawbone at said site an opening exposing the gingival end of said root means through said mucosa, said first transmucosal section being attachable at one end to said root means, and having at said one end substantially the cross-sectional size of said gingival end and at its other end substantially the cross-sectional size and non-round shape of said natural tooth where said tooth emerged through the surface of said mucosa, means to attach said one end of said first transmucosal section to said gingival end, said set further including a transfer coping for making a rigid model of said site faithfully replicating said opening, said coping being attachable at one end to said gingival end, and having at said one end a second transmucosal section which is substantially identical to said first transmucosal section and remote from said one end a supragingival section adapted for embedment in resilient modelling material, means to attach said second transmucosal section to said root means through said opening, said supragingival section including means to restrain said coping against turning in said modelling material.
