Manufacturer Narrative

The exact date of the event is unknown.The provided event date was chosen as a best estimate based on the date that the manufacturer became aware of the event.The complainant was unable to provide the suspect device lot number; therefore, the device manufacture date and expiration date is unknown.Initial reporter address: (b)(6).Device code 1562 captures the reportable event of bite block material separation.A bite blox was received for analysis, along with the piece that had reportedly detached.A visual evaluation of the returned device found damage to the dental rim and a piece of dental rim was detached.No other issues were noted.Based on the evaluation of the returned device, it is most likely that the user experienced excessive force which caused the device to break from the front face to the dental rim and detach a piece of the dental rim.It is possible that device handling during insertion or removal could have contributed to the reported event.Therefore, the most probable cause of the reported event is adverse event related to procedure, which indicates that the adverse event occurred during the procedure and the device had no influence on event.A manufacturing batch record review was unable to be performed as the lot number is unknown.However, a ship history review was performed to identify the most probable lots, and a dhr history review on the most probable lots did not identify any deviations within manufacturing/service processes that could have contributed to the event.
