If the bone volume and bone density of the alveolar bone in the missing teeth area meets the implant conditions two years after tooth extraction, implant denture restoration can be carried out; if not, fixed partial denture restoration or removable partial denture restoration can be chosen as follows. The requirements of implant surgery on the alveolar bone of the missing teeth area include the bone of the labial, buccal and lingual palatal side of the implant should be healthy and its thickness should be more than 1.5mm, the distance between the implant and the natural neighboring teeth should not be less than 2mm, and the root end of the implant should be more than 2mm away from the upper edge of the mandibular canal, and the distance between the implants should be more than 3mm if two implants are needed. If the recipient area meets the above requirements and the patient’s general health status can tolerate the implant surgery, implant denture restoration is feasible. If the patient’s general health condition is poor, or there is osteoporosis, osteochondrosis, osteosclerosis, etc., implant prosthesis is not feasible, and fixed partial denture restoration or removable partial denture restoration can be chosen. For the same disease, different patients have different conditions and different treatment options, so it is recommended to go to the hospital to receive professional treatment.
