[Design and application of the framework to prevent fracture of the magnetic denture].
OBJECTIVE
To investigate the methods to prevent magnetic denture from fracture.


METHODS
17 cases were selected and divided into group A and group B. 9 cases in group A only used resin base, 8 cases in group B were strengthened with frameworks. The rates of fracture or fissure in denture base were observed for 5 years, Chi(2) test was used for statistical analysis.


RESULTS
In group A, 3 cases were found with damaged base, there was no fracture happened in group B. Chi(2) test showed that there was significant difference between the two groups (P<0.05).


CONCLUSIONS
Frameworks should be designed to improve the strength of the magnetic denture base. It is easy to manufacture and apply with satisfactory clinical effects.
