Description

Metal fiber post and core is a restorative technique used when a tooth has lost significant structure but still needs support for a crown. Here's a quick rundown: *What it is:* A *post* (usually metal or fiber) is placed in the root canal to act as an anchor. A *core* is built around it to recreate the tooth structure, which later supports a crown. *Types of Posts:* 1. *Metal Posts:* - Stainless steel, titanium, or gold alloy. - Strong but can cause root fractures due to rigidity. 2. *Fiber Posts:* - Made of carbon or glass fibers embedded in resin. - Flexible, closer to natural dentin, reducing fracture risk. - Preferred for aesthetic cases (tooth-colored). *When it’s used:* - Extensive decay or damage where the tooth can’t support a crown alone. - After root canal treatment (since the tooth is weakened). *Procedure:* 1. Root canal treatment (if not already done). 2. Post space is prepared in the canal. 3. Post is cemented, core material (composite or amalgam) is built up. 4. Tooth is prepared for a crown. *Pros & Cons:* _Metal Post:_ - Super strong. - Risk of corrosion, root fracture. - Not aesthetic (visible if gum recedes). _Fiber Post:_ - Aesthetic, biocompatible. - Less stress on root. - Might not be as strong in high-stress areas.
