FDA's MAUDE database holds 3,538 reports that name the brand "AstraTech Impl EV 4.2S 9mm OS" (implant endosseous root-form), received between February 2021 and August 2026; the manufacturer given most often on reports is Dentsply Implants Manufacturing. Spellings of one product vary from report to report.

812 reports arrived in the 12 months to August 2026, up 18% from 689 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 (99.9%) and malfunction (0.1%); across all implant, endosseous, root-form reports (product code DZE) death is recorded in 0% and malfunction in 0.8%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are failure to osseointegrate (67.1%), loss of osseointegration (16.6%) and osseointegration problem (13.9%). The patient problems coded most often are failure of implant, inflammation and osteolysis. 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."
