58-year-old patient with no relevant medical history, with a vertical bone defect at the 3637 level caused by peri-implantitis. The patient comes to us after the implant has been removed.

Treatment: 3D bone reconstruction with the Khoury technique (autologous bone sheets) and placement of 2 Galimplant IPX® implants at 4 months. Bridge 36-37 in monolithic zirconia on rotational aesthetic straight abutments.

Initial clinical situation in which the absences of 36 and 37 and bone atrophy in that area are observed.

Soft tissues healed after implant exposure surgery and placement of 2mm height rotational aesthetic rectus multiposition abutments. The band of keratinized mucosa was 1-2mm. We would have preferred to perform a free graft to increase the keratinized mucosa, but the patient did not want to undergo such surgery.

Placement of the definitive monolithic zirconia prosthesis. The patient had a crossbite at 35 and the antagonist molars palatinized, so it was decided to do a rehabilitation of 36-37 also in a crossbite as the patient’s natural teeth were probably before losing them.
