The patient’s intuitive impression after tooth extraction is that there is a bloody pit on the gums, and this pit will take some time to heal, so the timing of the denture also needs to be grasped. If it is an ordinary tooth extraction, there is no bone trauma (of course, minimally invasive extraction is better), so that the healing is faster, if you choose to set the movable dentures, then 2 months can be, the elderly appropriate extension of one month, if you choose to set the fixed dentures, then at least 3 months, such as the alveolar bone healing can be completely. The same reason the elderly delayed one month. Jinan Hospital of Traditional Chinese Medicine stomatology Mei Xingcheng If the extraction trauma is relatively large, in the process of extraction, to remove some of the alveolar bone, and there is no filling of bone powder in the case, set all types of dentures, in accordance with the above time to extend one month. There is a limit to the time point for dentures, but not the later the better, generally not more than half a year, otherwise the neighboring teeth of the extracted teeth, because of the lack of support, or heavy burden, will be tilted, resulting in increased difficulty in dentures.
