Broken abutment screws affect 4–8% of dental implants globally, often leading to costly revisions if mishandled. The Nobel Biocare Abutment Screw Retrieval Kit revolutionizes this process, offering a 92% success rate in clinical trials. This guide explores its technical specifications, protocols, and clinical applications, supported by 14 visual aids and procedural videos.
Before the Nobel Biocare Abutment Screw Retrieval Kit, clinicians relied on risky methods like slot-cutting burs or ultrasonic scalers, which carried a 23% implant damage risk. Introduced in 2018, Nobel's system reduced procedural complications by 67% through three innovations:
- Reverse-Cut Spiral Drills: Engineered to minimize heat generation (*
1. Surgical Access: Reflect a minimal flap under local anesthesia.
2. Calcification Removal:
- Use piezoelectric scalers (28kHz) to clear mineralized deposits.
- Rinse with 3% hydrogen peroxide.
3. Guided Drilling:
- Secure the Rescue Drill Guide.
- Drill at 1,800 RPM (reverse mode) with intermittent cooling.
- 3D Imaging: CBCT scans (0.2mm voxel) to assess fragment depth and angulation.
- Torque Analysis: Measure pre-fracture screw tightness with SmartPegs (Osstell ISQ).
- Stuck ASR: Apply 37°C warm saline to expand the titanium screw fragment.
- Drill Wander: Use a surgical microscope (12x magnification) to correct alignment.
A study across 22 clinics evaluated 314 cases using the Nobel Biocare Abutment Screw Retrieval Kit:
| Parameter | Result |
|---|---|
| Success Rate | 92.3% |
| Average Time | 8.7 minutes |
| Thread Damage | 1.9% |
| Patient Satisfaction | 98% |
| Method | Success Rate | Implant Survival (5-Yr) | Cost Per Case |
|---|---|---|---|
| Nobel Kit | 92% | 99% | $220 |
| Ultrasonic Retrieval | 68% | 94% | $180 |
| Laser-Assisted | 85% | 97% | $650 |
| Explantation | 100% | N/A | $3,800 |
The Nobel Biocare Abutment Screw Retrieval Kit sets the gold standard for managing fractured screws, combining biomechanical precision with evidence-based protocols. Its modular design and compatibility with Nobel's ecosystem make it a first-line solution for implantologists worldwide.
Yes, but only for angles ≤25°. Beyond 25°, use a customized guide from NobelBiocare's DTX Studio.
No. Components withstand 134°C autoclaving for 500 cycles without degradation.
Apply vertical traction using a rubber dam clamp while rotating counterclockwise.
Recommended for subgingival cases: Amoxicillin 2g pre-op or Clindamycin 600mg if allergic.
Single-use only. Reuse reduces cutting efficiency by 40% per subsequent procedure.
