Core Features
This stainless steel screw post is purpose-built for endodontic restoration, with key features tailored to clinical needs:
1. Self-Tapping Thread Design
The external self-cutting thread creates a tight mechanical lock with the dentin wall, eliminating adhesive gaps and preventing loosening during long-term use.
2. Solid Stainless Steel Construction
Medical-grade stainless steel provides superior fracture resistance, making it ideal for posterior molar cases with high occlusal force.
3. Complete Size Compatibility
Our 12-Type and 20-Type series cover all common clinical root canal sizes, helping dental clinics simplify inventory management.
4. Cost-Effective Bulk Supply
As a factory-direct manufacturer, we offer competitive pricing for bulk orders, mixed-size packaging and customized OEM solutions for global dental distributors.
Clinical Applications
Screwed into the prepared root canal to provide stable mechanical fit for resin core and post core crown restorations, preventing the replacement material or crown from falling off.
Enhancing dental resistance:
Dispersing chewing stress, reducing the risk of fracture of remaining weak dental tissues, and prolonging the service life of affected teeth.
Suitable for residual root and crown restoration:
When most of the crown is missing and only the root remains, it serves as the foundation of the post core to support subsequent crown restoration and restore the shape and function of the tooth.
Ideal for bulk supply to dental clinics and labs worldwide.
Structure and Characteristics
Material:
Made of medical grade stainless steel, it has high strength, corrosion resistance, and can be repeatedly disinfected under high temperature and high pressure. It is safe and reliable for clinical use.
Design:
1. The shaft has self tapping threads that can be directly screwed into the prepared root canal wall, providing strong mechanical retention.
2. The tip is designed with a conical/rounded blunt shape, which guides the placement while reducing the risk of lateral penetration of the root canal wall.
3. The head is equipped with a card slot/square head structure, suitable for specialized screwdrivers, making it convenient for clinical screw in operations.
Specification:
Available in two full series: 12-Type and 20-Type, with S/M/L/XL specifications covering different root canal thicknesses for anterior and posterior teeth.
Key points for clinical use
Our medical-grade stainless steel posts feature stable strength and long service life for routine clinical use. Please follow the operating steps strictly:
- After finishing root canal therapy, confirm the working length via dental X-ray, then use professional drills to prepare the post space.
- Select the matching root canal post and screw it into the post space. Leave a section of the post exposed for subsequent resin core build-up.
- Control torque and insertion depth during installation. Excessive force may lead to root crack or tool fracture.
- Once the post is fixed, apply dental resin or adhesive to enhance bonding between the post and natural tooth tissue.
