Periodontal plastic surgery and regenerative periodontal surgery in a forty-seven-year-old patient with cleft lip and palate

Cleft lip and palate represent one of the most prevalent congenital malformations in humans, with an estimated prevalence of 0.45 per 1,000 individuals. During childhood and adolescence, affected patients undergo lengthy and complicated interdisciplinary treatment including treatment from specialists in pediatric medicine, oral and maxillofacial surgery, orthodontics, and otorhinolaryngology. The patient exhibited scarred adhesions with localized mucogingival deformities of the premaxilla (region 12 − 11), bilateral cleft lip and palate, and a complex underlying one-wall intrabony osseous defect on tooth 11, in addition to hard- and soft-tissue deficiencies at the dental implant in region 12. Following the administration of localized anti-infective periodontal therapy, regenerative periodontal surgery, regenerative surgical therapy of periimplantitis, and periodontal plastic surgery were performed. This resulted in a long-term, stable improvement in the clinical situation. Regenerative periodontal therapy and periodontal plastic surgery in patients with palato-alveolar cleft present a significant challenge due to the poor condition of the mucosa and gingiva adjacent to the defect and the insufficient bone dimensions. For this reason, it seems beneficial to include the periodontist in the interdisciplinary treatment team of a patient with cleft lip and palate from the outset. It is recommended that the patient be provided with dental prophylaxis measures and receive individualized oral hygiene instructions in addition to the main maxillofacial and orthodontic treatment. This approach would facilitate the identification of mucogingival issues at an early stage and the implementation of appropriate treatment.
