Immediate Loading of Six Implants in the Maxilla and Final Restoration with a Full-Arch Gold/Ceramic FDP Involving the Concept of Tilted Implants
A 61-year-old male patient with a failing fixed maxillary rehabilitation and a fixed mandibular rehabilitation requested a new fixed maxillary rehabilitation. The patient was wearing a temporary metal-reinforced maxillary bridge inserted two years before the consultation. He reported that his previous dentist did not want to insert a definitive framework because he considered the residual teeth to have a negative prognosis. The patient reported a history of recurrent caries and endodontic complications as the main reason for the previous extractions. The anamnesis was negative for periodontal disease and bruxism. The patient’s chief compliant was the mobility of his maxillary prosthesis, which needed to be re-cemented frequently, and discomfort during chewing.Moreover, the patient was not satisfied with the esthetic appearance of his maxillary teeth, which he found too long. The patient asked for a stable and comfortable fixed maxillary rehabilitation and firmly rejected any removable solution.

* General SAC assessment modifiers that are also part of the ERA. To avoid redundancy they are listed in this section even if no complete ERA has been made.
** Not applicable to the ERA of immediate placement cases and replaced by "Socket Integrity" listed below under "Surgical SAC Classification". For all other placement types this value is a classification determinant and listed here even if no complete ERA has been made.
