Values are presented as mean±SD.

HW1, change in horizontal ridge width 1 mm; HW3, change in horizontal ridge width 3 mm; HW5, change in horizontal ridge width 5 mm; VHB, change in ridge height at the buccal crest; VHL, change in ridge height at the lingual crest; VMC, change in the vertical height measured at the mid-crestal area; SD, standard deviation.
