A 50-year-old female patient, a non-smoker, presented to the private office with a crown-restored and endodontically treated tooth, 16. Due to pain symptoms, there was a need for treatment. Another clinician had previously offered the patient a treatment option including root-canal retreatment and/or apical root resection, and she requested a second opinion. Radiographic examination revealed a less than ideal rootcanal therapy that had caused periapical osteolysis. After evaluating all the different treatment options, it was decided to extract tooth 16 and replace it with a dental implant and crown.

* 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.
