Immediate Flapless Placement of an Implant in a Maxillary Left Central Incisor Site
A 29-year-old female patient presented for treatment to replace the upper left central incisor tooth with an implant- supported restoration. The tooth had been intermittently symptomatic for the previous 12 months. The tooth had originally suffered trauma about 15 years previously. Several endodontic treatments had been performed, including an apicectomy procedure to retain the tooth. The patient was healthy and a non-smoker. She had reasonable expectations in regard to esthetic outcomes and the risk of marginal tissue recession following treatment. At medium smile, the gingival margins of the upper teeth were visible, with a display of 3 to 4 mm of the gingival margins. Gingival recession of tooth 21 and a discrepancy in the gingival levels between teeth 11 and 21 was observable during normal speech and smile.

* 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.
