Clinical Case Report
Minimally Invasive Treatment of a Patient in Her Nineties After Removing Implants Affected by Severe Peri-implantitis
A 93-year-old female patient presented in September 2010 with an enlarged swelling on the lingual side of her lower incisors. At the time, she was essentially healthy, except for reduced vision due to bilateral age-related macular degeneration. She had been a heavy smoker (about 30 cigarettes a day) for the past 20 years after becoming a widow. The patient lived at home by herself, with full-time domestic support. An extraoral examination revealed nothing adverse. Intraoral plaque control was anything but ideal, and a soft-tissue tumescence was visible around the lingual aspect of 41–42. Because the nature of the lesion was not clear, a biopsy was carried out that revealed the inflammatory nature of the lesion. The panoramic radiograph showed six irregularly distributed mandibular implants supporting a full-arch prosthesis, with various degrees of interproximal peri-implant resorption. The periapical radiograph revealed interproximal bone resorption mesially and distally to implant 41.

* 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.
