Brief Summary

This study aims to evaluate the effect of biological drilling osteotomy protocol compared to conventional osteotomy protocol in delayed implant placement in the posterior mandible regarding implant stability Type of study design: Randomized Clinical Trial In patient indicated for delayed implant placement in the lower posterior mandible will the use of biological drilling protocol osteotomy compared to conventional drilling protocol osteotomy differ regarding implant stability at three months?

Outcome Measures

Primary Outcomes (1)

  • Implant stability (Implant Stability Quotient )

    Scale ranges from 1 to 100, the higher the Implant stability quotient the more stability

    Measurements will be taken immediately post surgical ,3 weeks,2 month and 3 months post surgical

Secondary Outcomes (4)

  • Crestal bone level changes

    Measurements will be taken immediately post surgical and after 3 months post surgical

  • Post-Operative Pain ( visual analogue scale)

    7 days post surgically

  • Post-operative swelling (Verbal rating scale)

    Swelling will be assessed 7 days post surgically

  • Post-Operative patient's Satisfaction

    3 months post surgically

Study Arms (2)

Biological drilling osteotomy protocol

EXPERIMENTAL

* Local infiltration anesthesia will be applied to all the patients participating in this study. * Full thickness mucoperiosteal flap reflection with 15c blade. * Osteotomy site preparation through sequential biologic drilling in healed bony site with a pilot drill at 800 rpm with irrigation initiates the drilling process, which is then followed by drills of different sizes and shapes at low speeds at 150rpm without irrigation. * The implant will be positioned in the osteotomy site and a healing collar will be placed. * The mucoperiosteal flap will be sutured in an interrupted manner with 5-0 proline suture material

Procedure: Biological drilling osteotomy protocol

Conventional drilling osteotomy protocol

ACTIVE COMPARATOR

* Local infiltration anesthesia will be applied to all the patients participating in this study. * Full thickness mucoperiosteal flap reflection with 15c blade. * Preparation for osteotomy site with conventional sequential drilling in healed bony site at 1200 rpm with irrigation. * The implant will be positioned in the osteotomy site and a healing collar will be placed. * The mucoperiosteal flap will be sutured in an interrupted manner with 5-0 proline suture material.

Procedure: Conventional drilling osteotomy protocol

Interventions

* Osteotomy site preparation through sequential biologic drilling in healed bony site with a pilot drill at 800 rpm with irrigation initiates the drilling process, which is then followed by drills of different sizes and shapes at low speeds at 150rpm without irrigation. * The implant will be positioned in the osteotomy site and a healing collar will be placed.

Biological drilling osteotomy protocol

* Preparation for osteotomy site with conventional sequential drilling in healed bony site at 1200 rpm with irrigation. * The implant will be positioned in the osteotomy site and a healing collar will be placed.
