Methods: Collagen matrix used with a coronally advanced flap was compared to a connective tissue graft used with a coronally advanced flap at 6 months and 5 years for root coverage achieved.
Results: Seventeen patients were available for the 5-year recall. Mean root coverage between 6 months and 5 years changed from 89.5% to 77.6% for collagen matrix and 97.5% to 95.5% for connective tissue. There was no significant difference between the therapies for changes in root coverage, keratinized tissue width, and probing depth. Patient satisfaction was similar for both therapies.
Conclusions: Collagen matrix is a viable long term alternative to traditional autogenous connective tissue when used in conjunction with a coronally advanced flap for root coverage procedures.
Dr. G’s comments: There is a trend for slightly better root coverage with autogenous tissue, but patients seem to prefer the lower morbidity of an allograft.
