After all teeth are missing, the use of complete denture restoration can restore most of the chewing function, improve pronunciation and facial appearance, and also relieve various psychological stresses caused by missing teeth. Gao Weinuo, Department of Stomatology, Xiyuan Hospital, Chinese Academy of Traditional Chinese Medicine It usually takes four visits from taking the first impression to wearing the dentures. That is: taking an impression – determining the occlusal relationship – trial teeth – wearing teeth. After the full denture is put in, because the soft, thick and thin mucosa (commonly known as the dental bed) is sandwiched between the harder denture and the alveolar bone, the thin mucosa is more likely to produce pressure and pain. If you experience pain or other discomfort, you will need to have it adjusted by your doctor. A special reminder is that it is best to keep your denture in place the day before your follow-up appointment so that the denture can be used to quickly and accurately diagnose and treat the painful area using the indentation left on the dental bed. In addition, complete dentures are not as stable as those with retainers, and they are not accustomed to be worn at first, especially the lower jaw denture, which tends to loosen and fall off when speaking or eating. After excluding the reasons of denture fabrication, it is necessary to practice and adapt gradually under the guidance of a physician. The adaptation period varies from person to person and generally takes 1-3 months. In conclusion, a successful full denture requires the joint efforts of both the patient and the doctor, and also depends on the patient’s oral conditions. Users are advised to adopt an optimistic and patient attitude, not to rush and blindly compare. They should actively cooperate with the physician and master the use of the new denture as soon as possible.
