Summary
Russian-designed "Turbo" orthodontic miniscrews show moderate primary stability, slightly less than "VectorTas" but better than "BioRay" miniscrews after 7 days of loading.
Area of Science:
- Orthodontics
- Biomaterials Engineering
- Dental Implantology
Background:
- Orthodontic miniscrews are crucial for anchorage in tooth movement.
- Assessing the stability of novel orthodontic devices is essential for clinical application.
Purpose of the Study:
- To experimentally compare the primary and secondary stability of Russian-designed "Turbo" orthodontic miniscrews against foreign analogues "Vector Tas" (USA) and "BioRay" (Taiwan).
Main Methods:
- Twelve self-drilling orthodontic miniscrews (4 each of "Vector Tas", "BioRay", "Turbo") were inserted into pig mandibles.
- Stability was measured using torque and Periotest immediately after insertion and after 7 days of loading at a 70° angle.
Main Results:
- All tested orthodontic miniscrews exhibited decreased torque and increased Periotest values after loading.
- The "Turbo" miniscrews demonstrated slightly lower primary stability compared to "Vector Tas".
Conclusions:
- The Russian-designed "Turbo" orthodontic miniscrews exhibit a stability profile between "Vector Tas" and "BioRay".
- Clinical performance of "Turbo" miniscrews requires further investigation despite promising results.
