   Abstract:	The mechanical fatigue resistance of the denture base seems to be a neglected part of treatment planning. Extreme overload can occur, which is only evaluated in the case of fracture. In full or partial edentia the dental base can be exposed to an extreme stress concentration which may be coupled with the incidental source of failure during processing of the denture. The aim of this lecture is to report cases, where we were able to overcome dental base fracture, which had not been foreseen earlier. In the first case a history of several fractures of an upper complete denture is presented. Metal net, framework and incorporation of glass fibres and reline werestages of the instructive problem solving process. In the second case a man wearing an overdenture with ball attachments under implant fixtures is presented. After multiple fractures of the dental base we used glass fibre reinforcement for repair. After this procedure there was an eventless period, which proves the mechanical resistanceof the denture base. In the third case presented both the denture base and the acrylic tooth were damaged. The multiple fracturecould also be treated with glass fibre reinforcement, which was successful. From these cases we concluded:1. Careful case history and treatment plan could have helped to overcome the subsequent problems.2. The clinical implication is that the glass fibre reinforcement can provide effective strength for the denture base. We could not neglect evaluation of the mucosa and bone support. In the following period we reinforced new dentures preventively with fibres in 15 cases. At the same time we also continued the repair the broken dentures of 10patients. The outcome exceeded our greatest expectations: no fracture was seen. However, further study is needed to extend the observation period.
