However, while aligners are effective for a range of malocclusions, they present limitations in achieving certain complex tooth movements—particularly anchorage-dependent mechanics such as molar intrusion, anterior retraction, or bodily translation.
This is where Temporary Anchorage Devices (TADs) have emerged as a valuable adjunct
The systematic review titled “Temporary Anchorage Devices in Clear Aligner Therapy: A Systematic Review” comprehensively analyzes the current literature on how skeletal anchorage systems can enhance the biomechanical efficiency of aligner therapy.
The authors evaluated a broad set of clinical trials, case series, and reports to determine the effectiveness, predictability, and safety of combining TADs with clear aligners in both extraction and non-extraction cases.
Key insights include:
TADs provide absolute anchorage to counteract unwanted reciprocal forces during retraction or intrusion.
Their use allows orthodontists to expand the limits of aligner therapy, treating malocclusions that were once considered beyond the scope of clear aligners alone.
Clinical applications include distalization of molars, anterior intrusion in gummy smile patients, and retraction of incisors in extraction cases without compromising posterior anchorage.
This review offers a practical and evidence-based foundation for clinicians looking to integrate skeletal anchorage into their aligner treatment plans
It also identifies gaps in the current research and calls for more randomized clinical trials with standardized protocols.
