Healthy teeth are good for eating and digestion, however, tooth decay, loosening and even extraction are quite common in the elderly population. Some elderly people think that the loss of two or three or even a dozen teeth does not affect their normal life, so as long as they can eat, they do not set their teeth, but in the long run, they cannot chew what they should be able to eat, resulting in unbalanced nutrition, and also causing harm to the surrounding healthy teeth, and the effect of dental implants is discounted at the same time. Therefore, timely dental treatment and restoration is very important for the health of the elderly. Before veneering, the elderly should first check and treat the remaining teeth in the mouth, and do the necessary basic treatment for the teeth that can be preserved, and extract the severely loose or decayed roots, etc. Some patients also need soft tissue surgery and alveolar bone repair surgery. There are three main types of veneers: 1. Fixed restorations: for elderly people with a small number of missing teeth and good condition of the remaining teeth. Fixed restorations generally require three follow-up visits, the first for tooth preparation and impression taking, the second for trial wear, and the third for bonding, with each interval generally taking 7-10 days. 2.Activated restoration: It is suitable for the elderly with a large number of missing teeth and poor condition of the remaining teeth. Active restorations require two to three follow-up visits, the first for tooth preparation and impression taking, the second for trial wear, and the third for some complex dentures. 3.Full mouth restoration: for the elderly who have no teeth in their mouth. Full mouth restorations generally require four follow-up visits. The first time to take the mold, the second time to determine the distance between the upper and lower jaw, the third time to try the teeth to see if the elderly are satisfied with the facial appearance, whether the bite is comfortable and natural, and the fourth time to try to wear trim. For the elderly wearing movable dentures in the use of the following aspects should be noted: 1, the first wear often have a foreign body feeling, pronunciation is not clear, and even chewing inconvenience, nausea, vomiting, etc., which requires patience to wear a week or two can be used to, if the mucosal pressure pain or ulcers, you need to go to the hospital for denture repair. 2, take off the denture can not be too hard, can not bite in place with teeth, otherwise it will lead to snap ring or abutment fracture. 3, when first wearing dentures, it is best not to eat hard food, should first eat soft food, gradually adapt, but even later do not eat too hard food, so as not to cause denture breakage. 4, develop the habit of cleaning dentures, usually after meals or before bedtime to remove the dentures brush clean, or use denture cleaning tablets soaked in water to avoid food impurities deposited.
