Biomechanical Stability of Dental Implants in Augmented Maxillary Sites: Results of a Randomized Clinical Study with Four Different Biomaterials and PRF and a Biological View on Guided Bone Regeneration
Table 2
Cumulative statistical evaluation of ITVs obtained in the subperiosteal-tunnel-technique (SP) study and INTRALIFT (IL) study by a one-way ANOVA test, Student’s -test, and post hoc multiple comparisons by Fisher’s least significant difference (LSD) to test mean insertion-torque-values and variance in each group and mean difference significance between all groups.
