The selection of thermoplastic polymers for constructing these dentures hinges, in part, on their demonstrated low toxicity and minimal allergenic potential. This characteristic is critical because the denture base comes into direct and prolonged contact with the oral mucosa, requiring a material that does not induce inflammation, irritation, or other adverse tissue responses. For instance, a poorly biocompatible denture material could lead to localized tissue inflammation, ulceration, or even systemic allergic reactions in sensitive individuals. The lack of adverse reactions allows for their extended usage for the patients that need them.
The biocompatibility of these dentures is further enhanced by the manufacturing processes employed. Injection molding techniques, often used in their fabrication, minimize porosity and surface irregularities, reducing areas where bacteria can accumulate. A smooth, non-porous surface is less likely to harbor microorganisms that can contribute to inflammation and infection. Additionally, the absence of methyl methacrylate, a common component in traditional acrylic dentures known to cause allergic reactions in some patients, can further improve biocompatibility. The reduced risk of allergic reactions is shown in the fewer amount of patient’s complains when using this type of prosthesis.
In summary, the biocompatibility of a denture significantly impacts patient comfort, oral health, and long-term treatment outcomes.
