Study arms

  • Experimental
    Diode laser

    Soft tissue incision with 940 nm Gallium Aluminum Arsenide diode laser, at implant recovery settings (2.5 W output power, average power: 1.25 W, pulse length : 1.00 ms, pulse interval: 1.00 ms) in second-stage implant surgery.

    Device: 940 nm Gallium Aluminum Arsenide Diode Laser

What researchers measure

Primary outcomes

  1. Postoperative pain on 1st day

    Patients score pain intensity with numeric scale ranging between 0(no pain) to 10(most severe pain) on the postoperative 1st day. Pain scores on the postoperative 1st day in each group are compared.

    Time frame: 1st Day

  2. Postoperative pain on 2nd day

    Patients score pain intensity with numeric scale ranging between 0(no pain) to 10(most severe pain) on the postoperative 2nd day. Pain scores on the postoperative 2nd day in each group are compared.

    Time frame: 2nd Day

  3. Postoperative pain on 3rd day

    Patients score pain intensity with numeric scale ranging between 0(no pain) to 10(most severe pain) on the postoperative 3rd day. Pain scores on the postoperative 3rd day in each group are compared.

    Time frame: 3rd Day

Secondary outcomes

  1. Number of analgesics used daily

    Analgesic consumption per day on postoperative 1st, 2nd and 3rd days.

    Time frame: 3 days

  2. Intraoperative bleeding

    Bleeding during surgical procedure was scored by the physician as 1=minimal, 2=normal and 3=excessive bleeding

    Time frame: During operation
