Abstract
CASE DESCRIPTION: Four cases of patients aged 41, 33, 43 and 68 years who presented periapical lesions and needed periodontal surgery for pre-prosthetic purposes. CLINICAL FINDINGS: The first case presented an intra-radicular retainer that was difficult to remove and likely to generate a root fracture. In addition, asymmetry of the gingival zenith was observed. The second case presented a complete crown at 16 with mesial marginal mismatch and subgingival margins distally. The third case presented a vestibular fistula with inflammation at the cervical level. The fourth case presented a vestibular fistula in the upper right lateral incisor. All patients showed apical lesions. TREATMENT AND OUTCOME: The first three cases received coronal lengthening and apical surgery in the same surgical procedure. In the fourth case, apical surgery was performed, and placement of implants 13 and 15 with a pontic of 14. During the clinical control and radiographs performed after the surgical procedures, bone filling of the lesion was found. CLINICAL RELEVANCE: Considering the results obtained, performing the periodontal and endodontic surgery procedures in a single surgical act is suggested. This reduces costs, travel, number of appointments, medication intake and post-surgical complications.
