Abstract
Abstract A prosthetic implant to replace damaged or diseased bone, especially in the maxillofacial region, is produced by producing a digital representation of the region of interest by CAT scan, using the data to create a model by stereolithography, and using the data also to produce the implant by CNC machining. The implant is an entire replacement extracts excised surgically, without need for reconstructing bone or soft tissue.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
102 words
A method of making a prosthetic implant comprising the steps of: obtaining a set of data defining body parts of interest from a patient in three dimensions, using said set of date to create a three dimensional model of at least part of the body parts of interest, and using the three dimensional model to develop and fit to size a prosthetic implant which entirely replaces body parts which are missing or are to be excised from the patient and which includes a body surface of skin and mucous membrane, and wherein the prosthetic implant extends through the skin or mucous membrane.
Claim 2
Independent Claim
102 words
A method of making a prosthetic implant comprising the steps of: obtaining a set of data defining body parts of interest from a patient in three dimensions, using said set of date to create a three dimensional model of at least part of the body parts of interest, and using the three dimensional model to develop and fit to size a prosthetic implant which entirely replaces body parts which are missing or are to be excised from the patient and which includes a body surface of skin and mucous membrane, and wherein the prosthetic implant extends through the skin or mucous membrane.
Claim 3
Independent Claim
45 words
A method of treating damaged, diseased or missing body parts having sound adjacent bone structures which comprises excising damaged or diseased body parts and selected adjacent parts, and replacing excised or missing parts entirely by a prosthetic implant secured to the sound adjacent bone structures.
Claim 4
Independent Claim
45 words
A method of treating damaged, diseased or missing body parts having sound adjacent bone structures which comprises excising damaged or diseased body parts and selected adjacent parts, and replacing excised or missing parts entirely by a prosthetic implant secured to the sound adjacent bone structures.
Claim 5
Dependent Claim
49 words
The method of claim 2 , in which both bone and soft tissue are replaced by a single prosthetic implant made of a material having a surface, wherein soft tissue is capable of growing onto the surface of said material in a manner to prevent the incursion of infection.
Claim 6
Dependent Claim
12 words
The method of claim 3 , in which said material is titanium.
Claim 7
Dependent Claim
60 words
The method of claim 2 , carried out by obtaining a set of data defining the body parts of interest in three dimensions, using said set of data to create a three dimensional model of at least part of the body parts of interest, and using the model to develop and fit to size the prosthetic implant prior to surgery.
Claim 8
Dependent Claim
17 words
The method of claim 1 , in which said body surface is the palate or nasal cavity.
Claim 9
Dependent Claim
23 words
The method of claim 1 , in which the set of data defining the body parts of interest is produced by CAT scanning.
Claim 10
Dependent Claim
19 words
The method of claim 7 , in which the data resulting from the CAT scanning is manipulated by computer.
Claim 11
Dependent Claim
33 words
The method of claim 8 , in which the data is manipulated to derive from a CAT head scan a set of data defining three dimensionally only the bony structures of a skull.
Claim 12
Dependent Claim
21 words
The method of claim 9 , in which a three dimensional model may conveniently is produced from aid data by stereolithography.
Claim 13
Dependent Claim
14 words
The method of claim 1 , wherein said prosthetic implant is made of titanium.
Claim 14
Dependent Claim
123 words
A prosthetic implant to entirely replace body parts which are missing or are to be excised from a patient and which includes a body surface of skin and mucous membrane, and wherein the prosthetic implant is capable of extending through the skin or mucous membrane, said implant being obtained using a method comprising the steps of: obtaining a set of data defining body parts of interest in three dimensions, using said set of data to create a three dimensional model of at least part of the body parts of interest, and using the three dimensional model to develop and fit to size the prosthetic implant; and said prosthetic implant is provided with mechanical attachment for the releasable attachement of a further prosthetic device.
Claim 15
Dependent Claim
123 words
A prosthetic implant to entirely replace body parts which are missing or are to be excised from a patient and which includes a body surface of skin and mucous membrane, and wherein the prosthetic implant is capable of extending through the skin or mucous membrane, said implant being obtained using a method comprising the steps of: obtaining a set of data defining body parts of interest in three dimensions, using said set of data to create a three dimensional model of at least part of the body parts of interest, and using the three dimensional model to develop and fit to size the prosthetic implant; and said prosthetic implant is provided with mechanical attachment for the releasable attachement of a further prosthetic device.
Claim 16
Dependent Claim
19 words
The prosthetic implant of claim 12 , provided with mechanical attachment means for the releasable attachment of a denture.
Claim 17
Dependent Claim
15 words
The prosthetic implant of claim 12 , wherein said prosthetic implant is made of titanium.
Claim 18
Dependent Claim
52 words
The prosthetic implant of claim 12 , wherein said mechanical attachment means for the releasable attachment of a further prosthetic device comprises a connector block, said connector block comprising a body and a post extending from the body, the post being formed with passages for rivets for attachment to a surgical plate.
Claim 19
Dependent Claim
26 words
The prosthetic implant of claim 15 , wherein the body of said connector block is rectangular and wherein said connector block is formed integrally from titanium.
