Study arms

  • Experimental
    Densah Bur Group

    Osteotomy site preparation using Densah burs in reverse (counterclockwise) condensing mode at 800-1500 rpm with copious sterile irrigation and gentle pumping motion, followed by early loading after 2 months.

    Procedure: Densah Bur Osseodensification

  • Experimental
    Modified Conventional Drilling Group

    Osteotomy site preparation using conventional drills sequentially in a clockwise direction, with the final drill operated in a counterclockwise direction, followed by early loading after 2 months.

    Procedure: Modified Conventional Drilling

Interventions

  • ProcedureDensah Bur Osseodensification

    Osteotomy site preparation using sequential Densah burs in reverse (counterclockwise) condensing mode at 800-1500 rpm with copious sterile saline irrigation and gentle pumping motion to preserve and compact bone.

  • ProcedureModified Conventional Drilling

    Sequential conventional drilling with the final drill operated in counterclockwise rotation to condense bone.

What researchers measure

Primary outcomes

  1. Implant Stability Quotient (ISQ)

    Implant stability measured using Resonance Frequency Analysis (RFA) with the Osstell Mentor device and SmartPeg. Measurements were recorded in four directions (every 90 degrees) and averaged per implant to provide an ISQ score (scale: 1 to 100, where higher scores indicate greater stability).

    Time frame: 12 months
