Thirty Pretreatment CBCT images of orthodontic patients, age 13-30 years were selected. The
samples were divided based on Square, Ovoid & Tapered arch form using Palatal bone thickness
was measured on both the right and left sides. The thicknesses of palatal hard tissue were
measured at the various coronal planes. Data were analyzed by One way ANOVA. The level of
significance was established at P<0.05. Bone thickness is highest anteriorly at mid palatal suture.
This is consistent for all the three arch forms, & it is statistically significant. Bone thickness
reduces posteriorly. When compared within three arch forms, bone thickness is found to be
highest in tapered arch form.Square arch form is having bone thickness higher than Ovoid arch
form. Bone thickness measurements on Right & left are significantly similar.Anterior mid palatal
region is suitable site for palatal mini-implant placement. Higher bone thickness in Tapered arch
form allows more sites for mini-implant placement. Bone thickness was higher in Square arch
form compared to Ovoid arch form
