CAD/CAM post and core |
A post and core is used to restore teeth that have undergone endodontic therapy and have significant loss of coronal structure. Traditionally, posts were cast in metal, but advancements in Computer-Aided Design and Computer-Aided Manufacturing (CAD-CAM) technology have introduced new possibilities for creating highly accurate, esthetic, and biocompatible post and core restorations. |
| Intervention |
Cast post and core |
A cast post and core is a custom-made metallic restoration fabricated in a dental laboratory to fit precisely into the prepared root canal and provide retention for a crown. It has been considered the gold standard for decades because of its high strength, adaptability to root canal anatomy, and proven clinical performance. Duration can be 1-2 years |

Brief Summary
|
The longevity and success of post and core restorations largely depend on the accuracy of fit between the post and the prepared root canal. Traditionally, cast metal posts and cores have been considered the gold standard due to their strength and adaptability. However, the advent of CAD-CAM technology offers a digital alternative that promises improved precision, reduced chairside time, and better standardization. This clinical trial aims to comparatively evaluate the clinical and radiographic accuracy of fit between cast metal post and core and CAD-CAM fabricated post and core systems, to determine which method provides superior adaptation and clinical performance. |
