a
Same letters mean no statistical differences; a, b, c. The Shapiro-Wilk normality test was performed and the nonparametric test results are presented in parentheses when normality is not satisfied. APT indicates anteroposterior thickness; AS, anterior space; ArS, articular slope; LS, lateral space; MLT, mediolateral thickness; MS, medial space; PS, posterior space; SD, standard deviation; SS, superior space; VHF, vertical height of fossa;. * P < .05, ** P < .01, *** P < .001.
