ABSTRACT

Introduction: in 1969, Ochsenbein and Ross classified gingival morphology into two types: scalloped, thin, or flat gingiva, and thick gingiva. Additionally, Seibert and Lindhe introduced the term "gingival biotype" to categorize gingiva into "thick-flat" and "thin-scalloped" types. During the World Workshop on the Classification of Periodontal and Peri-Implant Diseases, the term biotype was replaced with phenotype, characterized by three-dimensional gingival volume with boundaries at the mucogingival junction and thickness of the vestibular and palatal/lingual bony cortical. External factors, such as overcontoured prosthetic restorations, orthodontic treatments, brushing trauma, or mucogingival procedures, can modify the phenotype. Case description: a 60-year-old female patient presented at the Periodontology Department of the Autonomous University of Baja California with a diagnosis of gingival and periodontal health in a reduced periodontium. The patient was non-periodontal but had primary occlusal trauma with a thickness of 0.8 mm (thin phenotype) and RT1 in tooth. Procedure: a surgical procedure was performed to increase the thickness and width of attached gingiva in the anterior mandibular region. The "VISTA" technique was employed, accompanied by an acellular dermal matrix of porcine origin. Conclusion: modifying gingival conditions in a site with a thin phenotype or prior to treatments such as orthodontics or prosthetics significantly improves outcomes. Healthy gingival tissue provides stability, protection, aesthetics, and function in conjunction with dental restorations or modifications.
