Replacement of a Maxillary Right Central Incisor Using an Immediate Restoration Protocol
A healthy 54-year-old male was referred to a specialist prosthodontic clinic for the management of the maxillary right central incisor, tooth 11. It had been endodontically treated approximately 20 years before and was decoronated during trauma to the mouth. Emergency treatment provided by the referring general dentist provisionally restored the tooth with a prefabricated post and full coronal resin restoration. The patient requested a fixed replacement of tooth 11. The patient displayed a moderate lip line and, on wide smiling, a display of the interproximal papilla, and 1 mm of cervical gingival margin.

* 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.
