Dental bed atrophy, or alveolar bone resorption. After tooth extraction, especially in the front teeth, the alveolar bone resorbs to varying degrees in both height and width. After alveolar bone resorption, the effect of dental veneers will be affected, regardless of the type of veneers taken in the future. To prevent resorption of the alveolar bone. First of all, the doctor will suggest that the teeth to be extracted should be extracted as early as possible, if the time is too long, the alveolar bone may be resorbed due to inflammation and other reasons; secondly, patients with severe apical inflammation or defective labial and buccal bone can be implanted with artificial materials at the time of extraction or after a period of time in the extraction site, to preserve the width and height of the tooth bed; and very importantly, when extracting the teeth, use the minimally invasive extraction instrumentation, using minimally invasive extraction methods, to prevent the resorption of the alveolar bone, and the effect of veneers will be affected. The minimally invasive extraction method is used to preserve the alveolar bone as much as possible.
