FDA's MAUDE database holds 534 reports that name the brand "Invisalign System" (aligner sequential), received between September 2010 and December 2024; the manufacturer given most often on reports is Align Technology. Spellings of one product vary from report to report.

0 reports arrived in the 12 months to August 2026, against 28 in the 12 months before. FDA releases MAUDE data monthly; reports can arrive months after an event, so the newest months grow in later releases. The event types recorded are injury (86.9%) and other (13.1%); across all aligner, sequential reports (product code NXC) death is recorded in 0% and malfunction in 14%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are insufficient device problem information (13.1%), patient-device incompatibility (2.1%) and biocompatibility (1.1%). The patient problems coded most often are tooth loss, swelling and anaphylactic shock. FDA states that "MDR data alone cannot be used to establish rates of events, evaluate a change in event rates over time or compare event rates between devices. The number of reports cannot be interpreted or used in isolation to reach conclusions about the existence, severity, or frequency of problems associated with devices." It adds that the reporting system "has limitations, including the potential submission of incomplete, inaccurate, untimely, unverified, or biased data."
