ABSTRACT:
A dental system including a precision base and an abutment pattern for making a cast custom abutment for attachment to a dental implant body in a patient's jawbone. The base is made of a cast-to metal such as a gold alloy, and the abutment pattern is made of a burn-out material such as plastic. Wax may be added to the pattern for shape augmentation, and the pattern may also be machined for shape reduction. The pattern has a tapered post which is angulated with respect to a central axis of the base, thereby enabling construction of an angulated abutment which corrects for imperfect placement of the implant body in the jawbone.
