Late Placement of an Implant in a Maxillary Left Central Incisor Site
A 30-year-old female patient had lost tooth 21 and was referred to our clinic for consultation and treatment. Due to advanced apical infection, tooth 21 had been extracted two months earlier at another clinic and an acrylic-resin tooth had been bonded to the adjacent teeth. The patient desired implant treatment to avoid any damage to the adjacent natural teeth. While the patient had no history of any systemic disorder, she was a heavy smoker and exhibited medium to advanced periodontitis in the entire jaw. After the initial treatment to achieve a pocket probing depth of less than 4 mm and no bleeding on probing, a decrease in the height of the papillae mesial and distal to the extraction site and overall gingival recession were observed.

* 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.
