TPS implants were applied as the retention of dentures to 6 patients and the mobility of the 20 TPS implants in situ was examined with PERIOTEST®.The result was as follows.
1. The PERIOTEST® value (PT value) after inserting was -2.90 on the average(stdev:1.93).
2. The average PT value of TPS implants with functional loading was -3.20(stdev:1.13).
3. TPS implants showed no changes from minus PT value to plus PT value with the passage of time.
On investigation it was considered that TPS implants were very useful as the retention of dentures.
