Comparison of Primary Stability of Implants Installed by Two Different Methods in D3 and D4 Bone Types: An Study.

Objective: The purpose of the study is to assess the method of implant insertion in D3 and D4 bones and influence of insertion torque for achieving better primary implant stability.

Materials And Methods: A total of 32 specimens (wood blocks) simulating D4 and D3 bone were grouped into 1, 2, 3, and 4. In groups 1 and 3, the implant and abutment were placed by manual method while in groups 2 and 4 by motor-driven method.
