Immediate and definitive hollow bulb obturator for partial maxillectomy – A case report.

Abstract Abstract: For patients with partial or total maxillectomy defects, prosthetic rehabilitation with an obturator prosthesis is the gold standard treatment, offering optimal functional and cosmetic outcomes. The hollow obturator prosthesis reduces the load on the underlying and surrounding tissues. It is fabricated using a simple, cost-effective technique. A wax pattern is generated to replicate the defect area, which is then filled with water, frozen and used as a template. The resulting ice block is sandwiched between two layers of heat-cured acrylic resin, ultimately forming the prosthetic device. After curing, a hole is made to remove the ice block, leaving a hollow space, which is then filled with cold-cure acrylic resin, and a lightweight, uniformly thick prosthesis is created.
