Case

0.0The average rating is 0 stars out of 5.

In 2004, the patient, a smoker, began dental treatment at the ACTA graduate clinic. She was a TV producer exposed to a lot of stress in her job and had a sick husband. Her maxillary teeth had been extracted, as had the mandibular canines, premolars, and molars, with the exception of tooth 34. She received a complete maxillary denture and a mandibular skeleton denture. In October 2007, her maxilla was augmented by an oral and maxillofacial surgeon; in March 2008, implants (Biomet 3i, Palm Beach, Florida, USA) were inserted at that same clinic. In 2008, the patient was presented at the Department of Oral Implantology and Prosthetic Dentistry to request restorations for her implants. An implant-supported overdenture was planned. She also asked if we could restore her occlusion with fixed prosthetics.

* 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.
