Mean maximum pullout forces for cylindrical and conical screws in the traditional and modified groups. In the traditional group, the cylindrical and conical repair screws had mean pullout strength values of 3386.90 ± 370.94 N and 3338.80 ± 548.37 N, respectively; these values were 5095.63 ± 859.67 N and 4755.99 ± 819.60 N in the modified group, respectively. (Groups without statistically significant difference are indicated with “+” symbol).
