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

The aim of the work is to describe the technical procedures adopted to realize a custom-made clinical device, designed through a digital workflow, to improve the decompression of odontogenic cysts. After an incisional biopsy to confirm the histologic nature of the osteolytic jaw lesion, a digital impression of the dental arches, obtained by intraoral scanner, and a CBCT of the jaws, were acquired. The STL (Standard tessellation language) and DICOM files were matched and the decompression device was designed by the use of CAD software (Exocad, 3.1). The 3D-printed resin replica was obtained and cast with a surgical alloy. The delivered device proved to be safe and effective in decompressing the osteolytic lesions.
