A jaw prosthesis, also called a chin implant or denture, is a medical device designed to replace missing or damaged parts of the jaw. This can be especially important for people suffering from trauma, disease or congenital conditions that affect the structure and function of the jaw. A prosthesis helps to restore not only the physical appearance of the jaw but also its functionality, allowing for improved speech, chewing and overall quality of life. There are several types, including removable prostheses and fixed implants. Removable options are often used when extensive tissue loss has occurred, while fixed implants integrate with the bone, offering a more permanent solution. Advances in technology such as 3D printing and biocompatible materials have significantly improved the design and effectiveness of jaw prostheses, making them more comfortable and durable for patients. Regular follow-ups with dentists are essential to ensure proper fit and function and to monitor potential complications.
