Digitally Designed Decompression Device for Treatment of Odontogenic Cysts: Technical Note

Area of Science:

• Oral and Maxillofacial Surgery
• Biomedical Engineering
• Digital Dentistry

Background:

• Odontogenic cysts are common jaw lesions requiring effective decompression.
• Traditional methods for cyst decompression can be invasive and lack precision.
• Advancements in digital technology offer new avenues for custom device fabrication.

Purpose of the Study:

• To describe the technical procedures for fabricating a custom decompression device for odontogenic cysts.
• To evaluate the safety and efficacy of a digitally designed and manufactured device.
• To highlight the integration of a digital workflow in creating patient-specific surgical aids.

Main Methods:

• Histologic confirmation of osteolytic jaw lesions via incisional biopsy.
• Acquisition of digital dental arch impressions using an intraoral scanner.
• Combined use of CBCT (Cone-Beam Computed Tomography) and STL/DICOM file matching.
• CAD software (Exocad) for designing the custom decompression device.
• 3D printing of a resin replica followed by casting in a surgical alloy.

Main Results:

• A custom-made clinical device was successfully fabricated using a digital workflow.
• The device facilitated effective decompression of osteolytic jaw lesions.
• The delivered device demonstrated a favorable safety profile during clinical application.

Conclusions:

• A digital workflow enables precise and efficient fabrication of custom decompression devices for odontogenic cysts.
• This approach offers a safe and effective alternative for managing osteolytic jaw lesions.
• The integration of digital dentistry principles enhances surgical planning and device customization.
