Abstract
A 12-month prospective consecutive case series study was conducted to evaluate the effectiveness of a novel porcine collagen matrix to correct moderate to severe buccogingival recession defects. A total of 10 healthy patients (8 women and 2 men; age range: 30 to 68 years) with 26 maxillary and mandibular recession gingival defects > 4 mm deep were included. Healthy maturation of gingival tissues with natural color and texture matching the adjacent soft tissue areas were observed at all reevaluation visits. Complete root coverage was not achieved in all cases, possibly due to severe buccal bone loss in most of the selected cases, which negatively impacted the results. Nevertheless, when a novel porcine collagen matrix was used, a mean root coverage of 63.15% was achieved, and gains in clinical attachment level and keratinized tissue height were seen. Future randomized clinical trials are needed to further explore the potential of porcine collagen matrix for treatment of localized gingival recession defects.
