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.
