You can make all-ceramic teeth after gum recession, which needs to be combined with a full-mouth surface tomogram. If the neighboring teeth on both sides of the missing tooth are relatively stable and the gingival recession does not reach the cervical 1/3 of the neighboring teeth, the neighboring teeth can be used as abutment teeth, dental preparation and all-ceramic fixed bridge bonding restoration can be made, and when the recession is obvious, the bridge can be made close to the tissue surface to enhance the aesthetics of the denture. If the x-ray shows that the width and height of the jawbone at the missing tooth can meet the conditions for implantation, implants can be placed in the alveolar bone, and bone powder and periosteum can be placed at the same time to restore the height of the alveolar ridge, and after the formation of bone healing, all-ceramic crowns can be made to connect with the implants to perform the chewing function.
