[Glass fiber polymerization--an effective method of increasing fracture resistance of the denture base (case...

Three cases are presented to demonstrate how the application of glass fibres could be integrated into the treatment plan of removable dentures. In Case one the lack of space excluded the use of chrome-cobalt framework, but glass fibre reinforcement for the implant prothesis, secured by ball attachments, ensured structural stability. In Case two in order to keep the upper canine, an overdenture was constructed, which incorporated glass fibres in its dental base to prevent fracture propagation there. In Case three where the transfer of an extremely great chewing load to the dental base caused repeated fractures, the complex treatment of second framed work, fibres reinforcement and reline gave a stable satisfactory result over a long-term monitoring period. It was concluded, as presented, that the application of glass fibre reinforcement polymerised in the denture base can ensure structural stability and prevent fracture.
