Assessment of the Correlation between the Implant Distance and Primary Stability by Resonance Frequency Analysis

Table 1

Correlation analysis (alpha = 0.05).

Type	Variable 1	Variable 2
Hemimandible	Distance	Primary stability	0.122	0.252
Hemimandible	Density	Primary stability	0.271	0.010
Hemimandible	Cortical bone	Primary stability	0.162	0.128
Hemimandible	Tactile sensation	Primary stability	−0.185	0.081
Hemimandible	Torque	Primary stability	0.175	0.099
Polyurethane foam	Distance	Primary stability	−0.112	0.136

This table shows the variables that can modify the primary implant stability. Bone density is the only variable correlated to the primary stability () in the natural bone and the artificial bone.
