Study arms

  • Experimental
    Magnetic Mallet Group

    osteotomy site preparation using magnetic mallet

    Procedure: Magnetic Mallet Technique

  • Experimental
    Conventional Drilling Group

    osteotomy site preparation using conventional drilling technique

    Procedure: Conventional Drilling Technique

Interventions

  • ProcedureMagnetic Mallet Technique

    Osteotomy preparation for dental implant placement using a magneto-dynamic device (Magnetic Mallet) that delivers controlled percussive forces to condense bone and prepare the implant site in the posterior maxilla. Implants will be placed and early loaded after 2 months.

  • ProcedureConventional Drilling Technique

    Osteotomy preparation for dental implant placement using traditional drilling technique in bone and prepare the implant site in the posterior maxilla. Implants will be placed and early loaded after 2 months.

What researchers measure

Primary outcomes

  1. Implant stability

    The analysis of resonance frequency analysis (RFA) w made using an Osstell Mentor apparatus

    Time frame: 9 months

  2. Bone Density measurement

    Relative bone density records will be collected from the bucco-palatal view of the cross sectional plane using the Hounsfield unit

    Time frame: 9 months

  3. Marginal Bone Loss (MBL)

    For the calculation of marginal bone loss (MBL), the implant was used as a reference

    Time frame: 9 months
