Outcome Measures

Primary Outcomes (1)

  • Vertical bone height. (mm)Changes in augmented bone after transcrestal approach sinus augmentation.

    Measuring the changes in augmented bone volume after transcrestal approach sinus augmentation.

    Pre op; immediately post-op, at 6 months and 3 years from second stage surgery.

Secondary Outcomes (4)

  • Procedure time measurement. (min)

    The procedure time measurement will start after flaps are elevated at pilot drilling (2.4mm diameter). and it will be stopped when the implant was inserted and insertion torque was assessed.

  • Patients and operator satisfaction. (1-10 ruler scale)

    At the suture removal visit - 14 days after procedure.

  • Complications

    During the procedure, During the follow up - 14 days, 6 months after intervention.

  • The success rate of osseointegrated implants. (%)

    At 6 months and 3.5 years after intervention.
