Abstrakt: Introduction: The presence of keratinized mucosa (KM) around natural teeth is believed to be beneficial in certain restorative, prosthetic, and orthodontic situations. Lack of adequate KM is common and predictably treated by autogenous gingival grafts (AGGs); however, AGGs have the disadvantages of harvest site morbidity, limited donor site availability, and compromised esthetics.
Case Presentation: This case series presents the use of the xenogeneic porcine bilayer collagen matrix (BCM) in increasing the width of attached KM around natural teeth. Patients with a limited amount of KM, shallow vestibule, and aberrant frenum attachment were treated using this graft material. The patients were followed up to 4.5 years postoperatively and were evaluated regarding the amount of KM, gingival margin stability, and tissue esthetics.
Conclusions: Within the limitations of the sample size of patients in this report, the BCM appears to be a viable alternative option to AGG for increasing the width of KM gingiva around teeth. This method resulted in gain of KM, gingival margin stability, vestibular deepening, aberrant frenum elimination, and favorable esthetics in terms of color matching, texture, and contour blending. This xenogeneic graft material could be used in cases where the autogenous graft supply is limited or in highly esthetically demanding cases. Additionally, it could be an alternative option when a second surgical site is not desired by the patient or a less invasive procedure is preferred by the clinician in certain medical conditions. Well-controlled long-term studies are required to validate our limited clinical observations.
