Table 3.
Differences in regression coefficients (b) for implant length and implant diameter between the block densities for SICace®, SICmax®, and SICtapered®. b illustrated the mean percentage change in insertion torque per 1 mm change in implant length or diameter. Significant differences in the regression coefficients (b) in PCF 10 are denoted by * (p < 0.05) or § (p < 0.1). The term ratio reflects the quotient of bdiameter/blength.
