An alternative method for fabrication of a closed hollow obturator

Rehabilitation of apartial maxillectomy patient with silicone relined hollow bulb obturator – Case report

“…Literature reveals that, numerous materials have been put forth for fabrication of hollow bulb obturator. They include cellophane wrapped asbestos 9 , putty consistency elastomer 10 , modeling clay 11 , plasterindex 12 , salt 13 or thermoplastic splint material 14 .Parel et al 15 , Schneider 16 have used ice, sugar in the defect portion during processing and later removed by creating holes after processing.El Mahdy 17 used double-flask technique for fabrication of the hollow bulb obturator. But these techniques requiremore laboratory steps, like processing of the obturator bulb and the dentulous area separately.…”

The Hollow Bulb Obturator Fabrication, Where do We Stand in 2017

“…These methods have the disadvantages of adding more weight to the obturator and extra thickness to the hollow bulb obturator walls [9]. Minsley et al [21] suggested the use of a plaster index for the fabrication of the hollow bulb of the obturator, while simultaneously fabricating a heat-cured acrylic denture base used for maxillomandibular records followed by final waxing and processing of the obturator. Another technique is the double-flask technique described by El Mahdy [22] allowing for the complete fabrication of the hollow bulb obturator from the wax try-in stage to completion of the prosthesis; however, this technique requires extra laboratory steps, including heat processing of the obturator bulb and the tooth portion separately with two denture flasks and then heat processing these sections for the second time togetherdouble processing.…”

Prosthetic rehabilitation of necrotic maxilla sequelae of faulty denture: report of a rare case

“…Complete denture was processed with hollow bulb obturator [13,14,16]. Polished surfaces were made concave to enhance retentive ability by utilizing muscular support.…”
