What kind of teeth is the most suitable after tooth extraction is determined by the condition of the teeth in the mouth after tooth extraction. If only a few teeth are missing and the width and height of the alveolar bone are suitable, it is recommended to use implant restoration to set the teeth. Implant restoration does not damage other teeth, and after the implant is planted in the area of the missing teeth, then it is connected to a porcelain or all-ceramic crown. For those who are not able to accept implant restorations, a porcelain bridge or all-ceramic bridge can also be used, which requires grinding down the healthy teeth on both sides of the mouth, and then applying porcelain crowns on both the healthy and missing teeth to restore the missing teeth. If the number of missing teeth in the mouth is relatively large after tooth extraction, the alveolar bone resorption is more serious, especially in the elderly patients, for this group of people can also be used for activity denture repair.
