Sample size estimation
The sample size for this study was estimated using t-tests. The power sample size was calculated to detect a difference of 0.5 mm in vertical and horizontal bone resorption between the test and control groups. A power analysis in G-Power suggested a sample size of 16 participants, assuming 0.90 power with an α = 0.05. However, the sample size was increased to 20 patients due to the risk of drop-out during follow-up.The sample size calculation was done using G-Power software version 3.1.9.7 [
