The Merit to Phenotypic Modification Treatment for Dental Implants: Two Case Reports.

INTRODUCTION: The American Academy of Periodontology convened a Best Evidence Consensus workgroup in August 2019 in Chicago, IL to address whether the conversion of a thin to a thick tissue phenotype through various phenotype modification therapy (PhMT) can positively influence peri-implant health. CASE SERIES: PhMT was applied to two dental implant cases using subepithelial connective tissue grafting to increase peri-implant keratinized tissue. These cases demonstrated that when PhMT was used in either a reactive or proactive manner, the keratinized tissue improvement can support long-term peri-implant health. CONCLUSION: PhMT can prevent further gingival recession and provide a more stable environment conducive to maintaining peri-implant health.
