An investigation was conducted via telephone with the dental office to obtain further information related to the report that the device column motor failed, causing the overhead to drift down and touch the patient's head.The office stated a dental hygienist was positioning the patient for a pan scan using the orthoralix 9200 dde when the column motor failed and the overhead pan drifted down and was leaning on the patient's head.The patient was an (b)(6) female of average height (b)(6).The hygienist raised the overhead with her arm and removed the patient from the device.When overhead was released, it drifted down the column towards the floor.There was no injury to the patient or staff.There was no first aid administered to the patient.In addition, the office had followed up to make sure the patient was okay the following day.At this time, the office has not determined if the unit will be repaired or replaced.This concludes the investigation.

Manufacturer Narrative

The assembly, motor reducer, column was returned to the manufacturer for investigation.The main drive motor was examined and a physical inspection of the gear train revealed that the main drive pully had become loose and was spinning on the output drive shaft.It was observed that the set screw had backed off from the registration dimple on the output drive shaft.Based on the visual evaluation, the main drive motor was unable to hold the overhead in the upward position against the weight of the upper assembly as a result of the set screw backing off from the registration dimple on the output drive shaft.The root cause for the set screw backing off is inconclusive.This concludes the investigation.
