Abstract
RATIONALE: The treatment of a patient with an intrabony defect using periodontal phenotype modification therapy (PhMT) is alternative approach in correcting intrabony defects and changing periodontal phenotypes. PATIENT CONCERNS: A 27-year-old male patient arrived with a severe intrabony defect and a poor periodontal phenotype. The patient received PhMT, which includes nonsurgical periodontal therapy, bone grafting, and orthodontic treatment. After 1 year, there were considerable changes in the intrabony defect, periodontal phenotype, and general oral health. DIAGNOSES: A 27-year-old male patient had a profound intrabony defect (10 mm) and a poor periodontal phenotype (thin gingiva, high frenum attachment). INTERVENTIONS: The patient received PhMT, which includes nonsurgical periodontal therapy (scaling and root planing), bone grafting (allograft), and orthodontic treatment (correcting tooth placement). After 1 year, there were considerable improvements: Intrabony defect reduction (from 10 to 3 mm), improved periodontal phenotype (thickened gingiva, decreased frenum attachment), and improved dental health (lower pocket depths, increased attachment levels). PhMT successfully repaired the intrabony deficiency and altered the patient's periodontal phenotype. OUTCOMES: Improved dental health and aesthetics were the result of the comprehensive treatment, which addressed the problem as well as the patient's underlying periodontal features. LESSONS: The efficacy of PhMT in correcting intrabony abnormalities and altering periodontal phenotypes is demonstrated in this case study. This strategy presents a viable remedy for patients with intricate periodontal requirements.
