Clinical Case Report

Conventional Loading of Six Implants in the Mandible and Final Restoration with a Full-Arch Metal-Ceramic FDP

Arne Boeckler, Dean Morton

A 68-year-old, completely edentulous male patient presented for evaluation and treatment options. He reported excellent general health and was taking no regular medication. He had been edentulous for approximately 12 years, having lost his teeth to periodontal disease and dental caries. The patient’s chief complaint was incompetent function. His secondary concerns included his appearance and the desire for a predictable outcome. He attributed his reduced functional capacity to his lower complete denture, which he described as poor. He was particularly concerned with the denture’s instability and poor fit. In general terms, he was satisfied with the maxillary complete prosthesis. The maxillary prosthesis was characterized by adequate retention, stability, and support, although the fit was considered less than ideal.

  • * 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.
