Abstract:

BACKGROUND: The complete denture is a common repair form of prosthodontics clinical work, but the early fracture on the middle plate of complete denture is an important factor influencing the life of complete denture.
OBJECTIVE: To analyze the early failure of complete denture from a view of the mechanics.
METHODS: Based on the stress analysis, structural analysis, material property analysis of the plate, the real cause of early failure in the middle section was identified, thus proposing a new proposal to solve early fracture, improve fatigue strength of complete denture, and extend the service life of complete denture.
RESULTS AND CONCLUSIONS: The existing plastic manufacturing complete denture of high quality and high fatigue strength was superior to plate skeleton complete denture made of alloy steel or cast steel in the following aspects: ① prolonging the service life (generally permanent life is not available); ② reducing prices by 100% or lower; ③ comforting due to small quality.
