Clinical Case Report

Immediate Loading of Two Implants in the Mandible and Final Restoration with a Bar-Supported RDP

Geert Stoker

A 56-year-old female patient was referred to the clinic because of retention problems with her mandibular denture. She had been completely edentulous for more than 33 years and wore her sixth set of complete conventional dentures, which had been delivered 5 years previously. An oral surgeon had performed a vestibuloplasty in the interforaminal region of the mandible with a piece of skin tissue 12 years earlier. The panoramic radiograph and lateral cephalometric radiograph exhibited the hypotrophy of the inferior alveolar process. The mandible was a Cawood class VI,and the height of the mandible in the interforaminal zone was 15 mm.

  • * 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.
