Abstract
Aim: is to evaluate the insertion torque and initial stability of solid tapered threaded implants versus core- vent implant versus double grooved threaded implants.

Methodology: Blocks of fresh bovine bone samples were collected for the study. The bone blocks were stabilized by embedding them in dental plaster. A total of 24 implants were used for this study, a) Solid tapered threaded implants; b) double grooved threaded implants, c) Core-vent tapered threaded implants. Implant from each group was inserted in each bone block at insertion torque pre adjusted manually with a ratchet (cod BM-0292) and the maximum insertion torque was 90N/cm, firstly each implant from each group was inserted at torque 30N/cm then calibrate the part of implant inserted within bone by calibrating the part of implant outside the bone using digital caliber and subtracting the measure from whole implant length 12 mm, the same steps are done at torque 40N/cm and at torque 50N/cm. The removal torque of each implant was measured after implant insertion at torque 40N/cm by unscrewing the fixture using a ratchet. The implants inserted until the head of the implant was flush with the surrounding bone level. RFA measurements were carried out using the Osstell device.
