Functionalization of a Volume-Stable Collagen Matrix Using Liquid Platelet-Rich Fibrin: A Case Report Presenting a New Approach for Root Coverage
Abstract
This case report presents a novel approach for root coverage of multiple gingival recessions with a volume‐stable collagen matrix functionalized with injectable platelet‐rich fibrin (i‐PRF). A patient with multiple gingival recessions in the anterior maxilla was submitted to root coverage by coronally advanced flap with split–full–split incisions. Blood collection was performed before surgery and i‐PRF was obtained after centrifugation (relative centrifugal force (RCF) 400 g, 2700 rpm, 3 minutes). A volume‐stable collagen matrix was soaked with i‐PRF and applied as a substitute for autogenous connective tissue graft. A mean root coverage of 83% was observed after a 12‐month follow‐up period, and only slight modifications were detected in a 30‐month follow‐up consultation. The association of a volume‐stable collagen matrix with i‐PRF successfully treated multiple gingival recessions with reduced morbidity since a connective tissue collection was avoided.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
