Root Causes About Why My Dental Implant Screw Fell Out

Surgical Technique Factors:

  • Improper torque control: Incorrect torque during implantation, either too high or too low, may lead to screw loosening. Excessive torque can cause screw head fracture or excessive compression, damaging surrounding bone tissue. Insufficient torque may result in inadequate screw grip, leading to decreased implant stability.
  • Improper implant depth: If implant screws are not inserted to the appropriate depth, they may not fully utilize the support of the bone structure. Resulting in insufficient stability.
  • Angle error: The angle of implant screws should precisely match the optimal contact surface between the implant and bone structure. Any deviation may lead to uneven stress distribution, increasing the risk of loosening.

Material Selection:

  • Screw material: The biocompatibility, mechanical strength, and corrosion resistance of materials directly affect the long-term performance of screws. Poor-quality materials may result in corrosion, fatigue, or fracture under load.
  • Design flaws: The design of implant screws should consider load distribution and stress points. Inappropriate design may lead to unnecessary stress concentration during use, causing loosening.

Patient-Related Factors:

  • Bone issues: Patients with osteoporosis or insufficient bone density may have weaker bone tissue support for implants, potentially resulting in improper integration.
  • Lifestyle habits: Tobacco use, diabetes, or other conditions that may affect bone metabolism and healing. They can directly affect implant stability and long-term success rates.

  • Postoperative infection: Infections during or after surgery may can result in inflammation around the implant site. Which may hinder integration with bone tissue, leading to screw loosening.

Solutions After Dental Implant Screw Fell Out

1. Immediately re-fix or replace screws:

  • Once screw loosening or detachment is detected, promptly recall the patient for treatment. Inspect for any damage to the screw, replace if necessary with a new one, and ensure correct torque for re-fixation.

2. Use high-quality implant materials:

  • Select Johoty’s high-grade titanium alloy implant screws, which typically offer higher reliability and durability. Utilizing high-quality dental implant screws can reduce loosening issues caused by material defects.

3. Optimize implantation technique:

  • Ensure every step of the implantation procedure is up-to-date with the latest standards through ongoing effective training and education. Particularly focusing on implant angle and depth, crucial factors affecting implant stability.

4. Precise torque control:

  • Employ torque wrenches during implant screw installation. Strictly adhering to our recommended torque settings to avoid over-tightening or loosening.

5. Regular implant inspections:

  • Schedule regular implant maintenance and check-ups, utilizing X-rays or other imaging techniques to monitor the status of implants and screws. This aids in early problem detection and intervention.

6. Comprehensive patient assessment:

  • Conduct thorough oral and systemic health evaluations of patients before surgery to determine suitability for implant procedures. Special measures may be required for patients with osteoporosis or other conditions affecting bone healing.

7. Improve patient oral hygiene habits:

  • Guide patients regarding appropriate oral hygiene habits, and undergo regular professional teeth cleanings to reduce infection risks. And maintain a healthy environment around implants.

8. Interdisciplinary collaboration:

  • Collaborate closely with oral surgeons, prosthodontists, and periodontal specialists when dealing with complex implant issues. Leveraging each other’s expertise to develop optimal treatment plans.

Preventive Measures Before Dental Implant Screw Fell Out

Precise Surgical Planning and Execution:

  • Thorough preoperative planning: Utilize high-precision imaging techniques, such as CBCT (cone beam CT) to assess the patient’s bone condition and anatomy. Enabling the formulation of a rational implantation plan.
  • Accurate implantation technique: Ensure precise control of angle, depth, and position during implantation. It is to avoid screw overstress or improper loading due to technical errors.

Correct Torque Application:

  • Use of torque wrenches: Employ torque wrenches with preset torque values for screw fixation to prevent overtightening or loosening. Ensuring consistency and reliability with each operation. Regular tool calibration: Periodically calibrate and maintain torque wrenches to ensure their accuracy and functionality. Preventing operational errors due to tool malfunctions.
