Pre-Op

• Due to peri-implantitis at site #22 and malpositioning of implants in the maxillary anterior region (sites #11, #12, #21, and #22), implant removal using a Fixture Remover was planned, followed by implant replacement at #12 and #22.

Fixture Removal

• Neobiotech FR(Fixture Removal) Kit

View Product

• Removing prosthesis upper part

• Connecting Fixture Remover Screw (FR Kit)

• Removing the implants using Fixture Remover (FR Kit)

• Removed existing implants

Implant Placement and Provisional Restoration

• CMI IS-II active implants were placed buccally at #12 and #22 with intentional buccal exposure, considering occlusion and esthetics.

• Extensive guided bone regeneration (GBR) was performed to restore the alveolar defect and ensure proper implant positioning. The procedure utilized allograft bone, xenograft, and an absorbable barrier membrane.

• Suture

• Making provisional screw retained restorations by using temporary abutments

Final Restoration

• SCRP type of final restoration (labial view / lingual view)

• Panoramic radiograph of the final delivery of the prosthesis

Follow-Up

• 6-year follow-up panoramic radiograph, showing no evident bone loss

• Periapical radiograph of #12 and #22

• Labial view (6-year after final restoration)
