The Use of a Porcine Collagen Matrix for the Prevention of Buccal Bone Wall Resorption During Implant Placement in the Aesthetic Zone.
Trial Parameters
Brief Summary
Aim: To provide a comparative assessment of the clinical and radiographic effect of porcine collagen matrix when placed buccally at the time of single implant placement in the aesthetic zone vs autogenous connective tissue graft in terms of buccal bone resorption and soft tissue augmentation 6 months post operative. Histological assessment and patient reported outcomes were reported
