Fastening channel through a dental restoration

A computer program product for configuring a fastening channel through a dental restoration of a patient for fastening a retaining means retaining the dental restoration,

• the computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions being executable by a processor of a computer device to cause the computer device to:
• receive a 3D digital restoration model of the dental restoration of the patient, the dental restoration comprising an artificial tooth;
• receive a definition of an implant configured to receive the retaining means to retain the dental restoration on the implant based on at least a part of a dentition of the patient, the definition of the implant comprising a central longitudinal axis of the implant;
• determine a relative positioning of the dental restoration relative to the implant;
• determine a position of the fastening channel extending from the implant through the artificial tooth, the fastening channel comprising a first end and a second end, the first end being a connecting end providing a connection to the implant, the second end being a mouth within an outer surface of the artificial tooth configured for receiving a fastening means for fastening the retaining means to retain the dental restoration on the implant;
• in case the position of the fastening channel violating a set of one or more pre-defined positioning criteria, automatically adjust the position of the fastening channel by angulating the fastening channel such that the positioning criteria are satisfied,
• the angulating of the fastening channel comprising tilting a first straight section of the fastening channel relative to a second straight section of the fastening channel, the second straight section being a straight extension of the central longitudinal axis of the implant extending from the first end of the fastening channel to the first straight section, the first straight section extending from the second straight section to the second end of the fastening channel, and
• manufacture the dental restoration using the 3D digital restoration model as template, the manufactured dental restoration being a physical copy of the respective template.
