In the field of dental implantology, insufficient bone volume has long posed a major clinical challenge. When dealing with cases involving narrow alveolar ridges or tight inter-dental spaces, conventional implant diameters often fall short. The WEGO Sedga Narrow Implant Series was developed precisely to address these anatomical constraints, offering a new, reliable solution for complex indications.
Why Choose a Narrow Dental Implant?
When bone volume is limited, narrow dental implants excel by providing a minimally invasive alternative. In anterior regions or cases of horizontal bone deficiency, these implants can be placed with reduced need for extensive bone grafting procedures—enhancing patient comfort and reducing healing time, while still ensuring long-term functional and aesthetic results.
The WEGO Sedga Narrow Implant Series is designed specifically for:
Limited interdental space
Narrow alveolar crest width
With thoughtful design rooted in clinical needs, Sedga maintains the trusted stability of previous WEGO implant systems, while introducing refined features to meet the demands of modern dental implant therapy.
Key Design Features
- External Insertion Groove: The external driver design improves anti-fracture strength and minimizes damage to internal structures during placement.
- Micro-Ring Neck: Reduces cortical bone stress during insertion, preserves crestal bone height, and increases bone-to-implant contact area.
- Advanced Thread Geometry
- Deep threads: Enhance primary stability via lateral bone compression
- Dual-thread: Increases insertion efficiency
- Asymmetric thread shape: Optimizes stress distribution, reduces bone resorption risk
- Micro-Tapered Shoulder: Promotes elastic rebound of bone and enhances soft tissue support for improved esthetics.
- Root-Mimicking Body: Simulates natural tooth morphology for greater cutting stability and simplified surgical workflow in complex bone conditions.
- Self-Tapping Design
- Dual-cutting flutes: Efficiently accommodates bone debris and reduces compression
- Sharp apex: Eases insertion and increases surgical accuracy
Clinical Indications & Advantages
- Minimal diameter of Φ3.0mm addresses interdental width constraints without bone augmentation, simplifying treatment.
- Two-stage design allows for angled abutments, achieving superior esthetic outcomes.
- Morse taper connection with press-fit abutment ensures high mechanical stability and minimizes bone resorption and inflammation.
- Proven mechanical strength: The Φ3.0mm implant with a 25° angled abutment has passed 5 million cycles of 30° lateral load testing with no failure at the implant-abutment interface.
