Study summary

The study aims toward using autogenous bone grafts to solve decreased bone quantity in anterior maxilla while allowing the patient to recieve implants simultaneously (same time of grafting).

Read the detailed description
  • Chin bone ring will be harvested from patient's(10 in number) chin to augment the recent extraction socket with buccal bone defect, followed by implant placement.
  • The process of harvesting and placement of ring will be computer guided which adds lots of accuracy to the bone ring required size from the donor site and the proper placement of both the ring and the implant at the recipient site

Study arms

  • Experimental
    Interventional arm (Ridge augmentation with simultaneous implant placement)

    Chin bone ring is harvested using surgical guide to augment 1. anterior maxillary defective recent extraction sockets OR 2. remaining roots that need extraction and are accompanied with labial bone loss Associated with simultaneous implant placement with the aid of surgical guides

    Procedure: Ridge augmentation using chin bone ring with simultaneous implant placement

Interventions

  • ProcedureRidge augmentation using chin bone ring with simultaneous implant placement

    surgical guides are to be used to harvest chin bone ring, the rings are to be used for bone augmentation in extraction sockets (salama and salama classsification type II),simultaneously implant placement.
