The mean ESBG was 5.31\u2009mm for the cushioned grind\u2010out group and 4.64\u2009mm for the osteotome group. Multivariable regression analysis revealed that the cushioned grind\u2010out technique significantly facilitated ESBG (<jats:italic>p<\/jats:italic>\u2009=\u2009.028). Nineteen preparation sites experienced membrane perforation, with rates of 5.5% and 6.4% for the cushioned grind\u2010out and osteotome groups, respectively. However, the difference was not statistically significant (<jats:italic>p<\/jats:italic>\u2009=\u2009.920).
