Metal posts are widely used in restorative dentistry to provide additional support for crowns and core buildups in teeth with significant structural loss. They are made from durable materials such as stainless steel, titanium, or gold-plated alloys, these posts reinforce weakened teeth by anchoring the restoration securely within the root canal.These are available in parallel-sided or tapered designs, metal posts cater to different anatomical and functional needs. Parallel posts offer better retention, while tapered posts mimic the natural root shape for a more conservative preparation. Some designs feature threading for enhanced mechanical retention, while others rely on passive cementation.Though highly durable, metal posts can sometimes transmit stress to the root, making proper case selection crucial.
