**3. Conclusion**

Long-term deterioration of acrylic dentures in the oral environment is still an unsolved problem. Their allergic potential, mainly due to the residual monomer, is well known. New choices of resins, with better properties compared with acrylics, have been constantly developed for dental applications. Alternative processing technologies, such as casting, injection, light curing, CAD/CAM milling, and 3D printing, have been aiming to improving their qualities.

Choosing the right material for manufacturing full or removable partial dentures is very important because it has direct effect on their characteristics and lifetime, especially in case of allergic patients.
