An Alternative Method for Incorporating Fiber Meshes in Complete Upper Dentures

The most commonly used material for constructing complete dentures is polymethyl methacrylate (PMMA). However, the strength characteristics of PMMA, such as impact and fatigue strength, are poor, fracturing PMMA a common problem in prosthodontic practice. Reinforcing with various materials, carbon fibers, glass fibers (fiberglass), ultrahigh modulus polyethylene has been suggested to strengthen denture-base material. A encountered when packing resin on these specimens fiber slippage beyond denture edges. present study proposes an alternative method incorporating meshes into dentures, whereby thin filament self-polymerizing at perimeter mesh produced, giving clear stable shape that fits upper jaw cast. During placement shaped cast, positive-negative relationship created between which immobilizes during incorporation process.
