Abstract
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 that 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 made of a resilient gingiva replicating material in which to fabricate the artificial tooth, and methods of using the same.

Claim 7
Dependent Claim
34 words
The method of claim 5 wherein the healing member second transmucosal section shape is round with a diameter substantially replicating the width of the natural tooth where the natural tooth emerged from the gingiva.
Claim 8
Dependent Claim
47 words
The method of claim 1 wherein the making of the model further comprises: making an impression of the transfer coping; placing the gingiva-replicating material around the transfer coping; and making the model from the impression and the gingiva-replicating material with the transfer coping in the impression material.
Claim 9
Dependent Claim
35 words
The method of claim 1 wherein the gingiva opening and the healing member are round substantially replicating the width of the natural tooth where the natural tooth emerged from the gingiva at the gingival surface.
Claim 10
Independent Claim
197 words
A method of preparing an artificial tooth for placement on a natural or artificial root means with an overlying gingiva layer having an opening in said layer to the root means, which comprises: fastening a healing member to the root means through said opening, the healing member having a cross-sectional shape substantially replicating the emergence shape of the natural tooth where the natural tooth emerged from the root means to the gingival surface; causing the gingiva opening to form to the healing member shape; removing the healing member from the root means; fastening a transfer coping to the root means, the transfer coping substantially replicating the dimensions and contours of the healing member in said gingiva opening; making an impression of the transfer coping and the surrounding gingiva area; placing resilient gingiva-replicating material on the impression and around the transfer coping; making a model from the impression and the gingiva-replicating material with the transfer coping in the impression material for substantially replicating in the model the gingiva opening to the root means formed by the healing member; forming the artificial tooth in said replicated opening on the model; and installing the artificial tooth to the root means.
Claim 11
Independent Claim
197 words
A method of preparing an artificial tooth for placement on a natural or artificial root means with an overlying gingiva layer having an opening in said layer to the root means, which comprises: fastening a healing member to the root means through said opening, the healing member having a cross-sectional shape substantially replicating the emergence shape of the natural tooth where the natural tooth emerged from the root means to the gingival surface; causing the gingiva opening to form to the healing member shape; removing the healing member from the root means; fastening a transfer coping to the root means, the transfer coping substantially replicating the dimensions and contours of the healing member in said gingiva opening; making an impression of the transfer coping and the surrounding gingiva area; placing resilient gingiva-replicating material on the impression and around the transfer coping; making a model from the impression and the gingiva-replicating material with the transfer coping in the impression material for substantially replicating in the model the gingiva opening to the root means formed by the healing member; forming the artificial tooth in said replicated opening on the model; and installing the artificial tooth to the root means.
Claim 12
Dependent Claim
35 words
The method of claim 9 wherein the gingiva opening and the healing member are round substantially replicating the width of the natural tooth where the natural tooth emerged from the gingiva at the gingival surface.
Claim 13
Dependent Claim
29 words
The method of claim 9 wherein two different silicone materials are used for the impression material and the gingiva- replicating material to prevent bonding between said two silicone materials.
Claim 14
Independent Claim
150 words
A method of preparing an anatomically correct dental restoration for installation on a natural or artificial root fixed in jawbone 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 of a natural tooth emerging through said gingiva from said root, furnishing a solid material substantially replicating physical properties of bone overlaid with soft material substantially replicating physical properties of gingiva, forming in said soft material an opening replicating substantially identically said opening in said gingiva and forming in said solid material a substantial replica of said gingival aspect of said root, forming on said replica of said root an artificial tooth substantially replicating in said opening in said soft material the emergence shape and contours of said natural tooth, and installing said artificial tooth on said root.
Claim 15
