Transfer index of multiple angulated abutments in the restoration of an edentulous maxilla.

Osseointegration and the replacement of missing dentition with endosseous implants is a viable alternative to conventional prosthodontics with good long-term prognosis. This article describes a procedure for fabricating an index to accurately transfer the ideal position of several 17-degree angulated abutments from the master cast to the mouth in a predictable way. After the final try-in, evaluation of the space available and angulation of the implants is made to choose the appropriate abutments within the contours of the final restoration. A customized index was also developed to accurately transfer the position of those 17-degree angulated abutments from the master cast to the mouth in a precise manner.
