What is a primary advantage of a computer milled abutment compared to a cast abutment?

A primary advantage of a computer milled abutment compared to a cast abutment is that it does not usually involve laboratory misfits. This is largely due to the precision and consistency achieved through computer-aided design and manufacturing processes. When an abutment is computer milled, it is produced using digital scans and modeling, which allows for a high level of accuracy that reflects the unique anatomical complexities of each patient’s implant site.

In contrast, cast abutments often rely on the traditional method of creating a wax pattern that is then cast in metal. This process can introduce variables, such as shrinkage of the material or inaccuracies in the impression techniques, which may lead to misfits that require adjustments or remakes. The computer milling process minimizes these concerns, leading to a more reliable fit directly from the milling machine, enhancing the overall success of the prosthetic restoration.

This level of precision and reduced potential for error is crucial in implant dentistry, where proper fit is associated with better functional outcomes and patient satisfaction. While other options bring up notions related to cost, impression types, or accuracy, they do not emphasize how computer-milled abutments streamline the workflow and improve fitting reliability, which is a significant benefit in modern dental implant practices.
