Simplified technique for the fabrication of a hollow obturator prosthesis using vinyl polysiloxane

Hollow Maxillary Complete Denture

“…It has also been proved that prosthesis weight can be reduced by making the denture base hollow. Different approaches like using a solid 3-dimensional spacer, including dental stone [3][4][5][6][7], cellophane wrapped asbestos [8], silicone putty [9,10], or modelling clay have been used during laboratory processing to exclude denture base material from the planned hollow cavity of the prosthesis. Fattore et al [4] and Holt [9] have used different techniques for fabricating a hollow prosthesis.…”

Rehabilitation of severely resorbed maxilla with a hollow maxillary complete denture

“…3 The extensive volume of the denture base material in prostheses provided to patients with large maxillofacial defects or severe residual ridge resorption, reduction in prosthesis weight may be achieved by making the denture base hollow. Various weight reduction approaches have been achieved using a solid 3-dimensional spacer, including dental stone , 4 cellophane wrapped asbestos, 5 silicone putty, 2,6 or modelling clay 7 during laboratory processing to exclude denture base material from the planned hollow cavity of the prosthesis. This clinical report describes a technique for fabrication of a hollow maxillary complete denture in a patient with resorbed maxillary and mandibular ridges and increased interridge distance.…”

Technique to Fabricate Hollow Maxillary Complete Denture Using 3D Printed Template

“…Different materials like dental stone, 12 cellophane‐wrapped asbestos, 13 silicone putty, 2,14 light‐body coated gauze, 9 salt, 15 modelling clay, 16 caramel, 17 thermocol, 18 and glycerine soap 19 have been used as 3D spacers and are retrieved after processing to produce a hollow cavity. A photopolymer resin (Dental SG resin, Formlabs Inc, USA) containing methacrylic ester and photoinitiator is specifically manufactured for printing 3D parts for use as surgical guides among other applications 20…”
