Torque-fitting and resonance frequency analyses of implants in conventional sockets versus controlled bone defects in vitro

摘要: Abstract The primary stability of implants should be high on insertion into fresh extraction sockets. Torque-fitting and resonance frequency analyses (RFA) are used to assess implant anchorage stability. torque-fitting RFA placed in conventional surgical sockets with controlled coronal bone defects was compared. possible relation between explored. O 3.3 mm × 12 mm were 16 finalized 2.8 mm pilot drills the right iliac crests two cadavers (control). In test group, prepared by drill followed 4.2 mm twist a depth 6 mm create circumferential (50% loss). Primary assessed using torque values (ITV) RFA. Mean ITV measurements for groups (7.83 ± 0.91 N cm 40.88 ± 3.57) significantly lower than controls (14.80 ± 1 N cm 66.31 ± 0.9) (P
