An independent sample (15 subjects) showed high intraclass correlations ( r > 0.90) between replicate measurements of relative force, indicating low technical errors when multiple measurements are used. During T 0– T 1, the occlusion with clear overlay retainers showed a significant decrease in posterior surface area contact ( p 0.05). Assessments were made utilizing the T-Scan II (Tekscan, Inc., 307 West First St., South Boston, MA 02127) method of occlusal analysis at 3 time periods T 0, at debond all subjects received lower fixed canine to canine retainer and upper clear overlay retainers T 1, 2 weeks later 14 subjects received wrap-around retainers and the clear overlay retainer group was checked (18 subjects) T 2, occlusal contact assessment 2 months later for both groups.

Total 32 subjects, randomly assigned to two experimental groups, a clear overlay group and a wrap-around retainer group, were followed to assess occlusal changes. A prospective study to evaluate short-term changes in occlusal force and contact surface area associated with retainer wear.
