Early Loading of Two Implants in the Mandible and Final Restoration with a Retentive-Anchor-Supported RDP
A 63-year-old male edentulous and maladaptive patient presented with an inability to wear his existing complete maxillary and mandibular dentures. He had been edentulous for 41 years, and there had been three unsuccessful attempts by dentists to provide complete dentures for him. Efforts to wear both complete dentures were always initially encouraging, but over time, he invariably found that he was unable to wear the complete mandibular denture, and this pattern had persisted for 20 years. After seeing local newspaper advertisements, he requested having his complete mandibular denture stabilized with implants.

* 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.
