Patient Specific Implants (PSIs) for the Decompression of Odontogenic Cysts

A CBCT scan is performed before the surgical intervention.

Under local anesthesia, a full-thickness flap is prepared and cystostomy is performed.

A sample of the cyst lining is sent for histologic diagnosis.

The PSI is fixed on the surface of the bone using osteosynthesis screws.

The PSI enables the discharge of the cystic liquid into the oral cavity. The resulting decrease in cystic pressure induces bone healing. Patients are recalled monthly for controls and panoramic X-rays are performed to monitor the decompression.

Post-operative CBCT is performed six months after cystostomy to assess whether the cyst volume has been sufficiently reduced for enucleation, minimizing the risk of damage to anatomical landmarks.

Under local anesthesia a full-thickness flap is raised and the PSI is removed by unscrewing the osteosynthesis screws. The wall of the cyst is completely enucleated and the flap is sutured.

The residual cyst wall is sent for histopathologic examination.
