[Clinical study on the stability of palatal implant anchorage].
OBJECTIVE
To evaluate the clinical stability of the palatal implant anchorage system in orthodontic treatment.


METHODS
Sixteen osseointegrated implants (5.0 mm in diameter, 6 mm length) were inserted in the median palatal suture area of 19 patients with malocclusion (average age: 18.22 +/- 7.10 years, from 11 years to 35 years 1 month) as anchorage of active orthodontic treatment with MBT appliance. The standard lateral cephalogram after implant placement and before implant removing was taken to compare the radiological parameters.


RESULTS
The successful rate of palatal implant anchorage was 84.2%. The average duration of 16 palatal implant was 23.08 +/- 8.06 months (from 10 months to 36 months). There were no statistical differences in all parameters from the implant placement to the end of treatment. IL-X was from (62.88 +/- 5.85) mm to (62.45 +/- 6.70) mm, IL-Y was from (36.66 +/- 5.41) mm to (37.96 +/- 4.90) mm, IAP-PP was from (73.81 +/- 8.84) degrees to (74.72 +/- 9.22) degrees, IAP-Y was from (62.09 +/- 9.33) degrees to (63.85 +/- 10.96) degrees, U6-Y is from (20.80 +/- 5.87) mm to (21.49 +/- 6.00) mm.


CONCLUSIONS
Stable palatal implant anchorage was maintained during active orthodontic treatment.
