The goal of this clinical trial is to evaluate whether the magnetic mallet technique improves primary implant stability and clinical outcomes compared with conventional drilling during dental implant placement in the posterior maxilla with soft bone quality.
The main questions it aims to answer are:
Does the magnetic mallet technique result in higher primary implant stability compared with conventional drilling?
Does the magnetic mallet technique reduce surgical trauma and related complications compared with conventional drilling?
Researchers will compare the magnetic mallet technique with conventional drilling to determine differences in implant stability, bone response, and clinical outcomes.
Participants will:
Undergo dental implant placement using either the magnetic mallet technique or conventional drilling.
Be clinically and radiographically evaluated for implant stability and postoperative outcomes during follow-up
This study is a prospective clinical trial designed to compare the magnetic mallet technique with conventional drilling for dental implant placement in the posterior maxilla characterized by soft bone quality (D4 bone). Achieving adequate primary implant stability in this region remains a clinical challenge, and techniques that preserve and condense bone may improve treatment outcomes.
The magnetic mallet technique uses controlled electromagnetic impulses to prepare the implant site through bone condensation rather than bone removal, potentially enhancing primary stability and reducing surgical trauma. In contrast, conventional drilling relies on rotational cutting instruments that remove bone and may generate heat, which can negatively affect bone vitality.
Eligible participants requiring dental implants in the posterior maxillary region will be randomly allocated to one of two groups: implant site preparation using the magnetic mallet technique or conventional drilling. All implants will be placed following standardized surgical protocols.
Primary outcomes will include the assessment of primary implant stability using objective measurement methods. Secondary outcomes will evaluate peri-implant bone response, intraoperative and postoperative complications, and overall clinical performance during follow-up.
The results of this study aim to provide clinical evidence regarding the effectiveness and safety of the magnetic mallet technique compared with conventional drilling, particularly in soft posterior maxillary bone, to support evidence-based decision-making in implant dentistry

participants in this arm will undergo implant site preparation using the conventional drilling osteotomy technique according to standard clinical protocols before dental implant placement.
Device: Conventional drilling osteotomy
participants in this arm will undergo implant site preparation using the magnetic mallet osteotomy technique, which prepares the implant site through controlled bone condensation prior to dental implant placement.
Device: Magnetic mallet osteotomy
implant site preparation using sequential rotary drills according to standard protocol.

implant stability
Implant stability was assessed using Implant Stability Quotient (ISQ) values , ISQ \> 70: High stability. ISQ 60-69: Moderate stability. ISQ \< 60: Low stability.
Time frame: immediately after implant placement and at 3 months postoperatively
postoperative pain
Postoperative pain was assessed using a 10-point Visual Analog Scale (VAS), Visual Analog Scale (VAS), ranging from 0 (no pain) to 10 (worst possible pain).
Time frame: 7 days after surgery
Plan to share: Yes — individual participant data (IPD) that underlie the results reported in this study, after de-identification, will be shared with other researchers upon reasonable request. The data will be available beginning after publication of the primary results and may be used for academic and research purposes only.
