Abstract
Abstract A tooth replacement including an implant (24), abutment (2), and crown, where the abutment is shaped to match the tooth being replaced in inclination, orientation and gingival emerging profile. A method is also claimed where measurements of the teeth adjacent to the implant are taken along with other relevant oral measurements. These measurements are input to a computer which generates data for guidance and control of the forming of an abutment, including at least the size, shape, inclination, and orientation of the abutment. The abutment shape corresponds to that of the tooth being replaced, but of a reduced size such that the crown attached to the abutment matches the tooth being replaced. Preferentially, the abutment is both the healing and the permanent abutment which saves time, money and aggravation. The abutment is made of anyone or combinations of several metals and materials benign to the body, as are known in the art.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
145 words
A method for replacing a tooth, said tooth having shade and contoured surfaces, by an implant, abutment and crown comprising the steps of: measuring the teeth adjacent to the implant site, where said measurements define the size, position, orientation and inclination of the tooth being replaced, determining the type of tooth being replaced from the position in the jaw, said type being selected from the group consisting of central, lateral, cuspid, first bicuspid, second bicuspid, first molar, second molar and third molar, implanting a base, contouring an abutment to conform to the gingival emerging size and shape of the tooth being replaced, and further contouring the abutment to follow said respective shape and contours of the tooth being replaced, attaching the abutment to the base, and attaching a crown to the abutment, where the crown matches the shape and contours of the tooth being replaced.
Claim 2
Independent Claim
145 words
A method for replacing a tooth, said tooth having shade and contoured surfaces, by an implant, abutment and crown comprising the steps of: measuring the teeth adjacent to the implant site, where said measurements define the size, position, orientation and inclination of the tooth being replaced, determining the type of tooth being replaced from the position in the jaw, said type being selected from the group consisting of central, lateral, cuspid, first bicuspid, second bicuspid, first molar, second molar and third molar, implanting a base, contouring an abutment to conform to the gingival emerging size and shape of the tooth being replaced, and further contouring the abutment to follow said respective shape and contours of the tooth being replaced, attaching the abutment to the base, and attaching a crown to the abutment, where the crown matches the shape and contours of the tooth being replaced.
Claim 3
Dependent Claim
103 words
A method as defined in claim 1 wherein the step of measuring comprises the steps of: measuring the relative positions of the adjacent and other teeth to the position of the implant, abutment and crown, measuring the angles of the adjacent teeth and the angle of the face construction relative to the angles of the implant, abutment and crown, inputting said measurements into a computer, programming the computer to determine the size, orientation, inclination and shape of the tooth being replaced from said measurements, outputting from the computer information to guide and control the contouring of the abutment surfaces and the abutment dimensions.
Claim 4
Dependent Claim
50 words
A method as defined in claim 2 further comprising the steps of: under the guidance of the computer, fabricating an abutment to match the gingival emerging profile of the tooth being replaced, and fabricating a crown to match the shape, size and inclination and orientation of the tooth being replaced.
