Abstract
Abstract An arrangement of artificial teeth, preferably made of methacrylate, in which the teeth are mounted at the roots end in the natural sequence on a flexible plastic strip made of acrylate plastic in such manner that movement of the teeth in relation to each other is possible without their disengagement from said plastic strip. The arrangement is suitable for the manufacture of an artificial partial or total denture, in that on a preformed prosthesis in which a part of the teeth can already be contained on the complete prosthesis base, a fixing substance is applied to the free remaining part of said prosthesis base, and the dental arrangement is fitted into it.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
88 words
Dental arrangement for the manufacture of an artificial partial or total denture comprising at least two artificial teeth connected in natural sequence, characterized in that the artificial teeth are mounted along the roots side on a strip made of a plastic selected from acrylic or methacrylic esters which are flexible or remain soft in such a manner that the relative movement of the teeth with respect to one another horizontally as well as in the vertical direction is possible without disengagement of the teeth from the plastic strip.
Claim 2
Dependent Claim
88 words
Dental arrangement for the manufacture of an artificial partial or total denture comprising at least two artificial teeth connected in natural sequence, characterized in that the artificial teeth are mounted along the roots side on a strip made of a plastic selected from acrylic or methacrylic esters which are flexible or remain soft in such a manner that the relative movement of the teeth with respect to one another horizontally as well as in the vertical direction is possible without disengagement of the teeth from the plastic strip.
Claim 3
Dependent Claim
33 words
Dental arrangement according to claim 1, characterized in that the plastic of the strip is compatible with a plastic located on the upper side of a dental prosthesis and/or with an embedding plastic.
Claim 4
Dependent Claim
25 words
Dental arrangement according to claim 1 or 2, characterized in that the acrylic or methacrylic ester has a total of more than 6 carbon atoms.
Claim 5
Dependent Claim
15 words
Dental arrangement according to claim 3, characterized in that the ester is a hexyl ester.
Claim 6
Dependent Claim
145 words
Process for the manufacture of an artificial partial or total denture consisting essentially of the steps of: applying, on an already prepared prosthesis, in which a part of the teeth may already be contained on the complete prosthesis base, a first fixing substance to the free remaining portion of the prosthesis base; fitting in said first fixing substance one or more dental arrangements, which contain the missing teeth in their natural order, the missing teeth being mounted on the roots side on a strip made of an acrylic or methacrylic ester plastic which is flexible or remains soft, in such a manner that relative movement of the teeth with respect to one another, horizontally as well as in the vertical direction, is possible without disengagement of the teeth from the prosthesis base; and applying a second fixing substance which hardens around the fitted dental arrangement.
Claim 7
Dependent Claim
145 words

Claim 8
Dependent Claim
29 words
A process according to claim 5, wherein said second fixing substance is a rapid-hardening substance of monomer acrylic or methacrylic acidic ester which hardens around the fitted dental arrangement.
