Precision Endodontic Metal Screw Posts (Cross-Head System)
When reconstructing endodontically treated teeth with extensive coronal destruction, achieving predictable retention for core materials is paramount. Our Dental Metal Screw Posts provide a time-tested, dependable mechanical anchor inside the root canal. Manufactured from resilient, non-corrosive surgical stainless steel (also available in gold-plated coating), they offer superior tensile stability, precise apical threading, and anti-rotational core retention.
Key Clinical Advantages & Features
- Slotted Cross-Head Design: The precision-milled cross slots provide dual functionality: effortless engagement with standard manual insertion keys/drivers, and expansive undercuts that mechanically lock composite core materials to prevent crown dislodgement.
- Engineered Thread Geometry: Calibrated micro-threads distribute occlusal and masticatory loads evenly along the canal wall, avoiding localized stress spikes and preventing root fracture during seating[cite: 46].
- High Mechanical Resilience: Manufactured from medical-grade surgical alloy, offering exceptional flexural resistance without bending or fatiguing under masticatory chewing forces[cite: 46].
- Broad Dimensional Versatility: Available in 20 distinct proportional combinations of lengths (S, M, L, XL) and diameters (Φ1.05mm to Φ1.80mm), providing ideal anatomical adaptation for anterior roots, premolars, and divergent molar root canals[cite: 46].
- 100% Autoclavable: Safe for repeated hospital-grade steam autoclaving at 134°C / 273°F without loss of thread sharpness or structural degradation.

Step-by-Step Clinical Protocol
- Prepare and enlarge the root canal to the desired apical depth using a matched low-speed reamer/drill, avoiding eccentric wall movement[cite: 46].
- Using the dedicated manual wrench key, test-insert the selected screw post to verify length and passive depth[cite: 46].
- Remove the post, thoroughly rinse, disinfect, and dry the root canal and post surface[cite: 46].
- Coat the post lightly with permanent dental luting cement (glass ionomer or resin cement) and screw home gently without excessive apical force[cite: 46].
- Proceed with core build-up using composite resin or glass ionomer around the retention cross-head[cite: 46].
