To identify the most favorable sites that optimize initial stability and survival rate of orthodontic mini-implants, this study measured hard soft tissue thicknesses in median paramedian regions palate using cone-beam computed tomography (CBCT) determined possible sexand age-related differences these thicknesses.The sample comprised CBCT images 189 healthy subjects. The was divided into four groups according to age. A grid area set for measurement palate. Vertical lines were marked at intervals 0, 1.5, 3.0 mm lateral midpalatal suture, while horizontal 2-mm up 24 from posterior margin incisive foramen. Measurements made 65 points intersection between vertical lines.The palatal thickness decreased anterior region, with a decrease medial-to-lateral direction middle regions. While rather thick around aspects arch, it formed constant layer only 1-2-mm throughout Statistically significant observed sex age.The anterolateral as well suture seem be insertion mini-implants. differed by age sex; should considered planning placement
