Complete and partial dentures are prosthetic devices designed to replace missing teeth and restore function and aesthetics. Complete dentures are used when all teeth are missing in a jaw, whereas partial dentures replace only some teeth and are supported by the remaining natural teeth. Modern dentures are made from acrylic, metal, or flexible materials, offering improved comfort and aesthetics. The process involves taking impressions, fabricating the dentures, and making necessary adjustments for a proper fit. Regular maintenance, including cleaning and periodic relining, is essential to ensure their longevity. With advancements in dental technology, modern dentures now provide better fit, appearance, and functionality, improving the quality of life for individuals with missing teeth.
