Digital approach to fabricating an implant indexing device for dental implant abutments.

When dental implant abutments are fabricated, the use of an implant indexing device (IID) is recommended to evaluate the accuracy of a definitive cast. An IID is also useful to position multiple implant abutments on implants. Several methods have been used to fabricate an IID. However, the existing methods are labor-intensive. This article presents a digital workflow for fabricating an IID using computer-aided design and computer-aided manufacturing (CAD-CAM) technology with minimal human error.
