6,803 medical device reports received by FDA name the brand "Byte Night Aligners" (aligner sequential); the manufacturer given most often on reports is Straight Smile; received from September 2024 to August 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

1,202 reports arrived in the 12 months to August 2026, down 79% from 5,601 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 (87.8%) and malfunction (12.2%); 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 patient problems coded most often are deformity/ disfigurement, tooth fracture and laceration(s). 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."
