    Deeper insertion and perpendicular placement significantly improve temporary anchorage device (TAD) retention. Conversely, increasing the distance from the abutment head to the cortical plate reduces TAD stability.

    Area of Science:

    • Orthodontics
    • Biomaterials Engineering
    • Dental Implantology

    Background:

    • Temporary anchorage devices (TADs) are crucial for orthodontic anchorage.
    • Optimizing TAD insertion parameters is essential for predictable clinical outcomes.
    • Understanding factors influencing TAD retention is vital for successful treatment.

    Purpose of the Study:

    • To investigate how insertion depth, angulation, and distance from the cortical plate affect TAD retention.
    • To quantify the mechanical forces required to dislodge TADs under various insertion conditions.

    Main Methods:

    • 330 TADs from three manufacturers were inserted into synthetic bone at varying depths and angles.
    • Clinically relevant forces were applied to assess implant retention until failure.

    Installation Method to Enhance Quality Control for Fiber Reinforced Polymer Spike Anchors

    Published on: April 10, 2018

    Main Results:

    • Increased insertion depth consistently enhanced TAD retention across all tested devices.
    • Greater distance between the abutment head and cortical plate resulted in decreased retention.
    • A 90-degree insertion angle demonstrated significantly higher retention compared to 45 or 135 degrees.

    Conclusions:

    • Maximizing TAD penetration depth is key to achieving superior implant retention.
    • Minimizing the abutment head-to-cortical plate distance enhances TAD stability.
    • Optimal TAD placement at a 90-degree angle to the cortical plate maximizes retentive forces.
