  Cаse #3 Scenаriо: A 49-yeаr-оld male patient had been seen earlier by his general dentist and was later referred tо a periodontist for evaluation. When he presented to the initial evaluation, his chief complaint was “I have tenderness in the upper front gum area and it bleeds when I brush.” The patient is medically healthy and takes Aspirin occasionally for headaches.  The crowns in the maxillary central incisors had been delivered 3 months earlier. Periodontal exam revealed dental plaque–induced gingivitis and gingival (pseudo) pockets in the maxillary anterior sextant with 100% bleeding on probing in this sextant. Radiographic exam revealed normal bone levels throughout the dentition. It was clear that the margins of these crowns were more subgingival than the desired location, and accumulating plaque.   A radiograph of this area shows the distance from the maxillary anterior crown margins to the interdental bone is less than 1mm. What is a possible likely course of treatment needed to address the patient's CC?
