Conventional Loading of Eight Implants in the Maxilla and Final Restoration with a Full-Arch Gold-Ceramic FDP
A 35-year-old Caucasian female presenting with advanced periodontal disease involving both the maxillary and the mandibular dentition was referred for evaluation. The patient, a non-smoker in good general health, requested treatment for recurrent periodontal abscesses, tooth mobility, and discomfort during chewing, as well as restoration of her missing teeth with a fixed prosthesis to improve mastication and esthetics. All residual maxillary teeth exhibited plaque deposits, deep pockets, bleeding on probing, and class III mobility and were evaluated as hopeless. All residual mandibular teeth except tooth 37 could be maintained after periodontal therapy.

* 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.
