Abstract
Temporary anchorage devices (TADs) have revolutionized orthodontic biomechanics by providing reliable, compliance-independent anchorage. However, achieving optimal clinical outcomes depends not only on accurate miniscrew placement, but also on appropriate abutment selection and precise transfer of the miniscrew position to the laboratory. This lecture, “From Placement to Precision: Mastering Miniscrews, TAD Abutments, and Lab Transfer,” presents a comprehensive and clinically oriented approach to these critical steps.
A detailed analysis of different TAD abutments will follow, highlighting their design features, clinical applications, and selection criteria according to specific treatment goals. The lecture will demonstrate how choosing the appropriate abutment enhances force delivery, appliance versatility, and overall treatment predictability.
A key component of the presentation is the accurate transfer of miniscrew position from the patient’s mouth to the laboratory. Both conventional and digital workflows will be discussed, including impression techniques, scan protocols, and integration into CAD/CAM systems. Strategies to minimize errors and ensure precise appliance fabrication will be emphasized.
Clinical cases will be presented to illustrate real-world applications, demonstrating how proper coordination between clinical placement, abutment selection, and lab communication leads to superior outcomes. This lecture aims to bridge the gap between chairside procedures and laboratory execution, empowering clinicians to fully harness the potential of miniscrew-based orthodontics.
Learning Objectives
