The first step in fitting an All-On 4 is to prepare the placement of the four dental implants. An X-ray is taken to determine the state of the bone, and using digital surgical guidance, the implantologist selects 4/6 different anchorage points, strategically placed to ensure the best possible strength and stability of the prosthetic arch, avoiding the maxillary nerves. She will then incise the gums, drill into the bone and insert the titanium implants, which will be covered by a recovery cap, helping the screws to integrate into their bony and gingival environment. The first session, devoted to implant placement, can last from 1 to 2 hours, with each implant requiring 15 to 30 minutes of surgery. In 80% of cases, the operation is performed under local anesthetic. However, depending on the patient’s sensitivity and comfort, the dental surgeon may use moderate sedation or general anesthesia. In this case, a 1-night stay in Tijuana may be necessary. Most patients are able to return to their normal routine the day after the initial operation.
After 2 to 6 months, once the implants have been perfectly integrated and healed, and the type and shade of teeth have been chosen with the patient, the second appointment will be devoted to the integration of the definitive prosthesis, custom-made by the dental technician according to the 3-D images.
