Mandibular Rehabilitation with Replacement of Old Implants and Immediate All-on-4

The patient is a 76-year-old female. She complained of difficulties chewing, a lack of aesthetics and discomfort in the mandible. After the intra-oral examination and the completion of the complementary tests, we verified the existence of 4 remaining mandibular teeth in very poor condition. She had one root with a big cyst, and 2 old implants with a less than ideal position to be used in a total rehabilitation.

The treatment plan involved extraction of the remaining teeth and roots. Extraction of the two old implants. Leveling off the bony platform and the placement of 4 implants with immediate load.
