The first step: communication between doctors and patients before treatment, fully understand the expectations and wishes of patients, and rule out acute pathological state and acute infection. For teeth with no therapeutic value, the extraction time should be drawn up according to the specific situation, and temporary repair or modification should be carried out.

Step 2: Remove the teeth that can't be preserved during periodontal treatment. The adjacent teeth were treated, the alveolar bone and soft tissue to be implanted were treated before implantation, and the surgical guide plate was made.

Step 3: After the first two steps, the implantation operation can be performed.

Step 4: Maintain a non-invasive and healthy environment in the implant area during the whole jaw surgery, and make a transitional denture, so that patients can have a functional and beautiful transitional prosthesis on the basis of ensuring the non-invasive implant area. Complete periodontal treatment and follow-up maintenance steps, and complete all root canal treatment and necessary crown preparation.

Step 5: Expose the implant and put it into the gum shaper. After gingivoplasty, re-evaluate and remove any remaining natural teeth that affect the prognosis according to the needs of completing tooth preparation.

Step 6: Make an impression on the dental implant, try it on, and then adjust the occlusion and fixation.

Step 7: After all the operations are adjusted, do a good job in maintenance and follow-up oral hygiene and family maintenance guidance.
