Table 1.

ISQ of all dental implants between two groups at each time point. N1: nonsmoking patient NO.1; N2: nonsmoking patient NO.2; N3: nonsmoking patient NO.3; N: the mean value of nonsmoking patient; S1: smoking patient NO.1; S2: smoking patient NO.2; S3: smoking patient NO.3; S: the mean value of smoking patient; ns: nonsense; ISQ: implant stability quotient. P value was calculated from two-sided t-test.
