Split denture

A system for configurating a split denture, wherein the denture is a try-in denture, the system comprising a computer device with a processor operatively coupled to a computer-readable storage medium storing computer-readable program instructions which, when executed by the processor, cause the processor to control the system to:

• provide a digital 3D model of a denture, the denture comprising a plurality of teeth,
• split the digital 3D model of the denture into a digital 3D model of a base part and a digital 3D model of a teeth part,
• the base part comprising a first artificial gingiva portion, the base part further being configured to support the teeth part,
• the teeth part comprising the plurality of teeth of the denture and a second gingiva portion, the teeth part being configured to be mounted on the base part,
• provide the digital 3D model of the split denture for generating base part and the teeth part,
• the system further comprises one or more manufacturing devices for generating the base part using the 3D model of the base part and the teeth part using the 3D model for the teeth part,
• wherein for generating the base part a different first material or different first combination of materials with a different first degree of hardness is used compared to a second material or second combination of materials with a second degree of hardness used for generating the teeth part,
• wherein the first material or first combination of materials used for generating the base part is harder with the first degree of hardness being higher than the second degree of hardness of the second material or second combination of materials used for generating the teeth part, the lower second degree of hardness allowing for adjustments by a dentist.

A computer program product comprising a non-volatile computer-readable storage medium having computer-readable program instructions embodied therewith for configurating a split denture, wherein the denture is a try-in denture, wherein execution of the computer-readable program instructions by a processor causes the processor to control a computer device to:

• provide a digital 3D model of a denture, the denture comprising a plurality of teeth,
• split the digital 3D model of the denture into a digital 3D model of a base part and a digital 3D model of a teeth part,
• the base part comprising a first artificial gingiva portion, the base part further being configured to support the teeth part,
• the teeth part comprising the plurality of teeth of the denture and a second gingiva portion, the teeth part being configured to be mounted on the base part,
• provide the digital 3D model of the split denture for generating base part and the teeth part,
• the computer device further controlling one or more manufacturing devices to generate the base part using the 3D model of the base part and the teeth part using the 3D model of the teeth part,
• wherein for generating the base part a different first material or different first combination of materials with a different first degree of hardness is used compared to a second material or second combination of materials with a second degree of hardness used for generating the teeth part,
• wherein the first material of first combination of materials used for generating the base part is harder with the first degree of hardness being higher than the second degree of hardness of the second material or second combination of materials used for generating the teeth part, the lower second degree of hardness allowing for adjustments by a dentist.
