Retreatment of a Patient with Multiple Biological and Technical Complications and Failures
A 66-year-old patient presented because of retention loss of the tooth-supported FDP in the right maxilla (x-13-x-11). The mandibular full-arch implant-supported reconstruction (x-i34-i33-x-x-x-x-i43-i44-x) had suffered extreme wear. His medical history revealed high blood pressure, controlled with anti-hypertensive medication. The patient was a light smoker (2 to 3 cigarettes per day). The existing reconstructions had been performed alio loco about five years previously. That treatment had taken an extensive amount of time, and as early as during the fabrication of the reconstructions, multiple complications had occurred with the provisionals.

* 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.
