Dental implants have revolutionized tooth replacement, offering durable and natural-looking solutions. However, like any mechanical device, implant components can sometimes fail. One common issue is a stripped implant abutment screw, which can complicate treatment and increase costs. This comprehensive article explores the causes, removal techniques, cost factors, and preventive measures related to replacing a stripped implant abutment screw. It also provides detailed insights into the "ove stripped implant abutment screw code" and practical guidance for patients and clinicians.
An implant abutment screw is a small but critical component that connects the dental implant fixture (embedded in the jawbone) to the abutment, which supports the crown or prosthesis. These screws are usually made of high-quality titanium and are designed to withstand significant forces during chewing.
A stripped implant abutment screw refers to damage to the screw head or threads, where the screwdriver can no longer properly engage the screw. This can happen due to over-tightening, using the wrong driver, or screw fatigue, making removal difficult without damaging the implant or prosthesis.
Several factors contribute to screw stripping:
- Incorrect Driver Use: Using a driver that does not match the screw head can strip the screw.
- Over-tightening: Excessive torque can damage the screw head or threads.
- Material Fatigue: Repeated tightening and loosening can weaken the screw.
- Poor Implant Placement or Angulation: Improper implant positioning can increase stress on the screw leading to loosening or stripping.
- Occlusal Forces: Heavy or off-axis biting forces can cause screw loosening and eventual stripping.
Removing a stripped screw is a delicate process that requires specialized techniques and tools to avoid damaging the implant fixture.
1. Scaler Technique: Using a sharp scaler to tease the screw fragment counter-clockwise, sometimes aided by ultrasonic vibration to loosen the screw.
2. Creating a Slot: A small round bur can carve a slot in the screw head, allowing a flat driver to remove it.
3. Reverse-Tapping Rotary Instruments: Specialized kits use reverse-tapping burs to engage and unscrew the broken or stripped screw.
4. Wooden Stick Method: Using a sharpened wooden stick (from a cotton swab) dipped in water and denture cleaner to grip and rotate the screw out.
5. Ultrasonic Scalers and Lubricants: Ultrasonic vibrations combined with lubricants like mineral oil help reduce friction and ease removal.
- Screw Removal Kits: Commercial kits like Salvin's Implant Rescue Kit provide guides, drills, and taps specifically designed for screw removal.
- Hand Instruments: Fine forceps and needle holders can be used to grasp loosened screw fragments.
- Dental Handpieces: High-speed handpieces with diamond burs create access slots or grooves.
The cost to replace a stripped implant abutment screw varies widely depending on the complexity of the case and geographic location.
- Difficulty of Removal: Simple cases where the screw can be removed quickly cost less, while complex removals requiring specialized tools and multiple visits cost more.
- Damage to Existing Prosthesis: Sometimes the crown or abutment must be sacrificed to access the screw, requiring fabrication of new components.
- Dentist Experience and Location: More experienced specialists or clinics in urban areas may charge higher fees.
- Additional Procedures: Bone grafting or soft tissue surgery may be necessary if complications arise.
- Materials Used: Premium screws and abutments (e.g., titanium, DLC-coated) increase costs.
| Procedure | Estimated Cost (USD) |
|---|---|
| Removing Broken Implant Screw | $70 - $150 (simple cases) |
| Repairing or Replacing Abutment | $300 - $1,000+ |
| New Abutment and Crown Fabrication | $1,000 - $3,000+ |
| Complex Surgical Procedures (if needed) | $2,000 - $5,000+ |
Prevention is critical to avoid the complications and costs associated with stripped screws.
- Use the Correct Driver: Always use the manufacturer-specified driver for the abutment screw.
- Apply Proper Torque: Follow recommended torque values to avoid over-tightening.
- Regular Maintenance: Periodic check-ups to detect early screw loosening.
- Optimal Implant Placement: Proper angulation reduces stress on screws.
- Occlusal Adjustment: Flattening cusps and reducing cantilever effects help minimize forces on screws.
The term "ove stripped implant abutment screw code" relates to the specific dental procedure codes used for billing and documentation when dealing with stripped or broken implant abutment screws. Accurate coding is essential for insurance claims and proper reimbursement.
- D6096: Removal of broken implant retaining screw. This code is typically billed when the clinician removes a fractured or stripped screw from an implant fixture.
- D6095: Repair of implant abutment (by report). This code covers repairs to the abutment, which might be necessary if the screw stripping has caused damage.
- D6056: Prefabricated abutment, includes placement.
- D6057: Custom abutment, includes placement.
Using these codes correctly ensures that the dental office can claim payment appropriately and that patients understand the services rendered.
The first step involves a thorough clinical examination and radiographic imaging (such as periapical X-rays or CBCT scans) to assess the implant's condition and the extent of screw damage.
If the screw head is stripped, the dentist may need to create an access slot using a small round bur or ultrasonic scaler to engage the screw with a flat-head driver or specialized removal tool.
Using the appropriate technique (reverse-tapping burs, ultrasonic scalers, or manual methods), the screw is carefully unscrewed and removed to avoid damage to the implant threads.
Once the screw is removed, the internal threads of the implant are cleaned of debris and inspected for damage. If threads are damaged, additional repair or replacement of the implant might be necessary.
A new implant abutment screw is selected, often from the same manufacturer to ensure compatibility. The screw is inserted and torqued to the manufacturer's specifications to prevent future stripping.
If the original crown or prosthesis was removed or damaged, it is reattached or remade. This may involve impressions and laboratory work to fabricate a new crown.
Regular follow-up appointments are scheduled to monitor the implant's stability and the screw's integrity, ensuring long-term success.
In rare cases, the stripped screw may be so damaged or fused that removal is impossible without risking implant damage. Options then include:
- Leaving the screw in place: If it does not compromise implant function or hygiene.
- Surgical removal of the implant: Followed by bone grafting and implant replacement.
- Custom abutments: Designed to bypass the damaged screw area.
These scenarios significantly increase treatment complexity and cost.
Patient: 52-year-old male with a dental implant in the lower right molar region.
Issue: The patient reported loosening of the crown. Upon examination, the implant abutment screw was found stripped, preventing crown removal.
Procedure: Using a screw removal kit with ultrasonic vibration and reverse-tapping burs, the dentist successfully removed the stripped screw without damaging the implant. A new abutment screw and crown were placed.
Cost: Removal ($120), new abutment screw and crown fabrication ($2,200), total $2,320.
Outcome: The patient regained full function with no complications after 12 months.
Replacing a stripped implant abutment screw can range from a simple, low-cost procedure to a complex, expensive treatment depending on the severity of the stripping, damage to the implant or prosthesis, and the techniques required for removal. Proper diagnosis, use of specialized tools, and adherence to manufacturer protocols are essential for successful screw retrieval and replacement. Preventive measures such as correct driver use and torque application significantly reduce the risk of screw stripping. Understanding the "ove stripped implant abutment screw code" helps in accurate billing and insurance processing. Patients experiencing loose or stripped screws should seek prompt dental care to avoid further complications.
Stripping usually occurs due to using the wrong screwdriver, over-tightening, implant misalignment, or repeated screw manipulation.
Simple screw removal and replacement can take less than an hour, while complex cases involving new abutments and crowns may take several weeks.
Yes, with specialized tools and careful techniques like reverse-tapping drills and ultrasonic scalers, screws can often be removed without implant damage.
Costs vary but typically range from $70 to $150 for removal alone; additional costs apply if new abutments or crowns are needed.
Use the correct driver, apply proper torque, maintain regular dental check-ups, and ensure proper implant placement and occlusal adjustments.
