Values are presented as mean±standard deviation (mm).
ANOVA: analysis of variance.
a)Statistically significant decrease in height compared to baseline (P<0.05) by 1-way ANOVA; No statistically significant difference in graft height change was detected among different tooth types (P>0.05) by ANOVA for repeated measures.
