Abstract
Method for producing a base part of a set of artificial teeth, or a set of artificial teeth having a base part, comprising the step of forming the base part by a rapid prototyping process, e.g. 3D lithography and, in particular, 3D laser lithography. Furthermore, the invention relates to a method of establishing a data set representing the shape of a base part of a set of artificial teeth, wherein a gum area or a model thereof is scanned and/or a model of a base part is scanned and/or the shape of the base part is simulated on a computer.
Claims24
A method of producing a base part of a set of artificial teeth, or a set of artificial teeth having a base part, wherein in the base part or on the base part the artificial teeth are provided, wherein the base part is individual for each individual patient and wherein the base part is fitted onto a gum area in which teeth are missing, comprising the steps of:
- recording the shape of a gum area, using the recorded shape of the gum area for fully or partly determining the interior shape of the base part, modeling a model of the base part onto a model of the gum area, recording the shape of the model of the base part and using the recorded shape of the model of the base part for fully or partly determining the outer shape of the base part;
- or
- recording the shape of a model of a gum area, using the recorded shape of the model of the gum area for fully or partly determining the interior shape of the base part, modeling a model of the base part onto the model of the gum area, recording the shape of the model of the base part and using the recorded shape of the model of the base part for fully or partly determining the outer shape of the base part;
- the method further comprising the steps of:
- forming the base part with fastening means for artificial teeth, said fastening means being formed integrally with the base part, the lower end of an artificial tooth being provided with a recess into which a fastening means can be inserted;
- and
- forming the base part by a computer-aided production process.
A method of establishing a data set representing the shape of a base part of a set of artificial teeth, or the shape of a set of artificial teeth including a base part,
- wherein in the base part or on the base part the artificial teeth are provided, wherein the base part is individual for each individual patient and wherein the base part is fitted onto a gum area in which teeth are missing, wherein
- a) a gum area or a model thereof is scanned, the method further comprising the steps of:
- fully or partly determining the interior shape of the base part by using the scanned gum area or the scanned model thereof;
- modeling a model of the base part onto the model of the gum area, recording the shape of the model of the base part and using the recorded shape of the model of the base part for fully or partly determining the outer shape of the base part;
- the method further comprising the steps of:
- forming the base part with fastening means for artificial teeth, said fastening means being formed integrally with the base part, the lower end of an artificial tooth being provided with a recess into which a fastening means can be inserted;
- and/or
- b) a model of a base part is scanned and/or
- c) the shape of the base part is simulated on a computer.
