Oral Lichen Planus Associated with the Peri-implant Mucosa
This case describes the ongoing management of a 64-year-old healthy, non-smoking female patient with erosive oral lichen planus (OLP) affecting the gingivae and the buccal and lingual mucosa. The peri-implant mucosa was also affected subsequent to implant placement. The patient had osseointegrated implants (four in the maxilla, four in the mandible) placed following extraction of hopeless teeth and a healing period. The patient had a history of OLP prior to implant placement and had been referred to an oral-medicine specialist for definitive diagnosis and treatment. She exhibited generalized oral mucosal involvement. Following a clinical assessment, biopsy, and blood tests, she was treated with topical corticosteroids. Systemic prednisolone was reserved for severe flare-ups. Amphotericin lozenges were used in combination with corticosteroid treatment to prevent the development of oral candidiasis.

* 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.
