Patient Specific Implants (PSIs) for the Decompression of Odontogenic Cysts
Sponsor: Semmelweis University
Summary
This study aims to assess the feasibility of the decompression of odontogenic cysts using Patient Specific Implants anchored subperiosteally using osteosynthesis screws.

Conditions
Interventions
Preoperative Cone Beam Computed Tomography (CBCT) scan
A CBCT scan is performed before the surgical intervention.
Cystostomy
Under local anesthesia, a full-thickness flap is prepared and cystostomy is performed.
Histology to confirm the initial diagnosis
A sample of the cyst lining is sent for histologic diagnosis.
Patient Specific Implant
The PSI is fixed on the surface of the bone using osteosynthesis screws.
Cyst decompression
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.
CBCT
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.
Enucleation
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.
Histology performed on the entire lining of the cyst
The residual cyst wall is sent for histopathologic examination.
