NCT07825896

Brief Summary

Background: Teeth loss in the posterior mandible initiates residual ridge resorption, this causes difficulty in implant placement so ridge augmentation must be done either simultaneous with implant placement or in a staged approach Aim: To evaluate the effect of autogenous sticky bone with PRF membrane and xenograft with collagen membrane with simultaneous implant placement clinically on primary and secondary implant stability, and radiographically on bucco-lingual width gain, bone density and crestal bone loss

Outcome Measures

Primary Outcomes (4)

  • Change in implant stability

    Implant stability will be recorded immediately after placement (1ry stability) and after 6 months (2ry stability ) by using osstell device. The result is presented in form of ISQ value from 1 to 100, the higher the ISQ the higher the stability of implant

    up to 6 months

  • change in bucco-lingual bone thickness

    All participants in the study will be advised to undergo CBCT before implant placement to measure bucco-lingual bone thickness, and again 7 days postoperatively and 6 months after implant placement to assess the following.

    up to 6 months

  • change in marginal bone level

    At buccal, lingual, mesial, and distal sites will be evaluated radiographically from the shoulder of the implant to the alveolar crest. The mean marginal bone loss after the placement of implants will be calculated by subtracting baseline value from the values obtained at 6 and 9 months post implant placement

    up to 9 months

  • change in ridge width

    Will be measured immediately and after 6 months, bone width will be measured for each implant at three levels (2, 5, and 10 mm from the alveolar crest) and the mean will be calculated for each implant at each time interval.

    up to 6 months

Secondary Outcomes (3)

  • change in pain scores

    up to 7 days

  • change in edema scores

    up to 7 days

  • change in bone density

    up to 6 months
