Primary Stability in Various Levels of Impacted Implants: An Ex Vivo Study
The aim of this study was to examine the primary stabilization of different vertically impacted bone implants. Implant stability was measured by resonance frequency analysis. Forty-five dental implants were used and divided into 3 groups. Group 1 was placed 4 mm (1/3 impacted), group 2 was placed 8 mm (2/3 impacted), and group 3 was placed 12 mm (fully impacted). Implant stability quotient values were measured on the longitudinal and transversal axis by 2 independent researchers. The fully impacted group showed the significantly highest value among the groups (P < .05). There were statistically varying implant-stability quotient values between researchers. None of the 1/3-impacted implants' value reached a 70 implant-stability quotient value.
