Multidisciplinary treatment combined with a modified apically positioned flap technique for generalized stage III grade C periodontitis: A five-year follow-up case report.

RATIONALE: The management of patients with generalized stage III grade C periodontitis involves complex considerations, particularly in cases of inadequate peri-implant keratinized mucosa. We present a case study highlighting the multidisciplinary management of periodontitis and the feasibility of a modified apically positioned flap procedure to increase the width of the keratinized mucosa at the implant site during the second stage of implant surgery.

PATIENT CONCERNS: A 45-year-old woman presented to our hospital with a 4-year history of tooth mobility that caused difficulty chewing and bleeding gums when brushing.

DIAGNOSES: The patient was diagnosed with generalized stage III grade C periodontitis.

INTERVENTIONS: The patient underwent a initial periodontal therapy, periodontal surgery, endodontic treatment, implant treatment, prosthodontic treatment, soft tissue augmentation procedures during the second stage of implant surgery, and supportive periodontal therapy.

OUTCOMES: The patient showed a healthy periodontal status and stable occlusal function after 5 years of follow-up.

LESSONS: Multidisciplinary management of generalized stage III grade C periodontitis requires full consideration of systematic periodontal therapy, personalized treatment planning, and patient compliance; in particular, a modified apically positioned flap procedure may serve as an option for soft tissue augmentation at the dental implant site.
