Immediate dental implantation is a relatively complex treatment procedure that requires an experienced surgeon to strictly follow certain steps for implantation, as follows: 1. CBCT is routinely taken before surgery to measure the thickness, height and width of the alveolar bone, check the roots that need to be extracted, and determine whether the indications for immediate implantation are met; 2. The digital implant guide is used for the immediate implant surgery, and the patient is routinely sterilized and paved before the surgery, under local infiltration anesthesia, minimally invasive extraction, preparation of the implant socket according to the depth and diameter of the alveolar sockets, and expansion step by step, implantation of the appropriate length and diameter, guided bone tissue regeneration technology at the same time, and the feasibility of immediate crown restoration according to the initial stability of the implant; 3. If conditions permit, the patient can be fitted with a temporary crown. If conditions do not permit, the surgeon will choose to close the wound and wait for the implant to complete osseointegration before proceeding with the subsequent treatment.
